We re-install ecFlow with ecFlowUI from time to time at ECMWF on the workstations and on ecgate (see Getting Started with ecFlowUI). On this page we will document the main features and improvements with each installation. Note that this page was only started in December 2016 and so does not contain updates from the previous months. The release notes for the 'core' of ecFlow are here.

We recommend that you 'Watch' this page in order to receive e-mail notifications when it is updated.

Updates for version 5.9.0

Area	Description	Notes
Remote access via teleport	Improvement: remote access to ecFlow servers at ECMWF was improved as described here: Using ecFlowUI via the ECMWF Teleport gateway
Log server	New feature: added new request type to the log server to transfer only the portion of the log file from a given byte offset. With this ecFlowUI can highly optimise file transfer from log servers supporting this option (see below).
Log server	Improvement: previously the log server applied a text filter on the file contents it transmitted. This filter is now removed and the log server sends the full file contents leaving the optional filtering to the client applications.
Log output	Improvement: the log file access has been refactored internally to optimise loading updates for the currently viewed log file. When pressing the (blue) reload button in the Output panel: for files served by a logserver an incremental file transfer is initiated whenever the logserver is supporting this request type for local files only the increment is added to the text viewer when there is no increment (the file did not change) the text viewer is not updated at all (previously it always reloaded the whole file) A full reload can still be initiated by using the Load whole file button under the More actions submenu. In the same submenu the Load current jobout file button was added to load the current jobout file.
Log output	Improvement: rearranged buttons in the Output panel. Some buttons were moved into a menu accessible from the More actions button to the right.
Log output	Improvement: the progress bar for remote file transfers now only appears after a delay so it is not visible for short enough transfers. Previously it appeared immediately the file update was requested.
Log output	Improvement: added options to show/hide the directory listing panel at the bottom. This can be done using the toggle button at the top of the Output panel. On top of that a close button was added to the directory panel. When the directory panel is hidden it is also disabled and ecFlowUI does not try to update it automatically.
Log output	New feature: added button to the directory listing panel in the Output panel to show detailed information about how the directory information was updated.
Log output	Improvement: In the various views and info labels the file size label for files larger than 1 GB is now displayed with 1 decimal place precision, e.g. 1.3 GB (previously it was displayed as an int).
Node search	New feature: added new Status change option called "older than" to the filter. It is used to filter nodes with status changes older than the specified period.
System server list	New feature: the system server list access has been redesigned. Previously a centrally installed file defined this list for each ecflow installation at ECMWF. From this version on multiple system server files can be defined independently from the actual installation using either the ECFLOW_SYSTEM_SERVERS_LIST environment variable or specific settings in the ecFlowUI configuration dialogue. See the full description here: System server list files in ecFlowUI
Timeline and server load	Improvement: added button (see the << or >> icon) to show compacted file information in the Timeline and Server load panels. In compact mode only the file name is visible in the file information label, but the full information is still displayed as a tooltip.
Manage servers	Improvement: when changing a host or port or renaming a server all the user interface components (views and panels) are automatically adjusted to the changes. Note: when the host or port altered the original server will be removed from the tree view and a newly created one will be added to the end of the tree.
Manage servers	Improvement: reports error for newly created servers when host or port contain whitespace characters. When a server added/modified in the ui the following rules are applied: name: cannot contain whitespace characters except space. Cannot start or end with space. host: cannot contain whitespace characters port: can only contain digits user: cannot contain whitespace characters
Preferences dialog	Improvement: when opening the Preferences dialog it will show the last used tab in the current configuration category.
Command line help	Improvement: when ecflow_ui is started with the -h option (help) the version info is also displayed
Context menu	Fix: fixed an issue when shortcuts were not visible in the the node context menus.
Context menu	Fix: fixed an issue when setting variable value for multiple nodes was only applied to the first selected node.
Info panel	Fix: fixed an issue when Info panel tabs were not notified about selection change when they became unselected
Output panel	Fix: fixed issue when a stray coloured rectangle appeared in the Output panel message label when it was selected

Updates for version 5.8.1

Area	Description	Notes
Log output	Fix: fixed an issue when fetching remote log output via the log server did not work in the Output panel

Updates for version 5.8.0

Description

Notes

Log server

New feature: The server settings tab now contains two parameters in the "Fetching files" section to define custom log server host/port for the given server (by default these are specified by the ECF_LOGHOST and ECF_LOGPORT variables).

When both the server and port are non-empty their values are used to connect to the log server instead of using the ECF_LOGHOST and ECF_LOGPORT ecflow variables.

When a custom logserver host/port is defined for a given server it is displayed in the tooltip in the tree view.

Log output

Improvement: when refreshing the output of a running task in the Output panel, the text view occasionally scrolled to the beginning of the file. This was improved and now the text view always scrolls to the end of the file in these situations.

Log output

Improvement: the text view in the Output panel now only switches into large file view mode when the file size is >= 40MB (the previous limit was 1MB).

Log output

New feature: added button to the Output panel to control text wrapping in the log output panel. Please note it does not work in large file view mode (for file size >= 40 MB).

Log output

New feature: improved text navigation actions in the text view in the Output panel. There are 4 new buttons available to go to the start/end of the document or start/end of the current line. On top of that the text navigation shortcuts were improved and harmonised between the standard and large file view modes. The current list of navigation shortcuts are as follows:

Action	Linux (Leap42)	MacOS
start of document	Ctrl+Home	Cmd+Up
end of document	Ctrl+End	Cmd+Down
start of line	Home	Cmd+Left
end of line	End	Cmd+Right
scroll up by one row	Up	Up
scroll up by one row	Down	Down
scroll up by viewport	Page Up	Fn+Up
scroll up by viewport	Page Down	Fn+Down

Log output

New feature: added button (see the << or >> icon) to show compacted file information in the Output panel. In compact mode only the file name is visible in the file information label, but the full information is still displayed as a tooltip.

Installation

Improvement: ecFlowUI can now be built with both Qt6 and and Qt5. If both versions are available the build process automatically selects Qt6.

Exit

Fix: fixed an issue when ecFlowUI crashed on exit when multiple windows were open

Exit

Fix: fixed an issue when an empty window appeared on the screen on exit

Tree view

Fix: fixed an issue when the node status was not updated automatically in the tree view

Tree view

Fix: fixed an issue when ecFlowUI crashed if the z key was pressed in the tree view with no nodes selected

Timeline

Fix: fixed an issue when could not cancel log file transfer in the Timeline panel

Updates for version 5.7.0

Area	Description	Notes
Startup	New feature: the ecflow_ui command now allows to use the -cmd option to specify a command that the executable (ecflow_ui.x) should be started through. E.g. ecflow_ui -cmd proxychains4 will invoke the executable as proxychains4 ecflow_ui.x
Search dialog	New feature: The internal widget type of the Search dialog was changed (technically it was converted from a QDialog to a QMainWindow) so that users can minimise/maximise it. This conversion causes a change in behaviour: when the parent ecFlowUI window is minimised/maximized the Search dialog does not follow it (since it is no longer a QDialog) pressing enter still invokes the search but the search button is not highlighted any longer (this is only available in a QDialog)
Trigger graph	New feature: double-click on a node in the trigger graph looks up the node in the tree view
Node Context Menu	New feature: the Clear threshold flag action was added to the node context menu. Can be accessed on tasks as: Special -> Clear threshold flag
Node Context Menu	New feature: the Clear restored flag action was added to the node context menu. Can be accessed on restored nodes as: Special -> Clear restored flag
Search dialog	New feature: the archived, restored, no_script and threshold (=slow job creation) flags were added to the flags option the Search dialog.
Session manager	New feature: the list shown in the session manager is now sortable
Shell command history	Fix: fixed an issue when the shell command history popped up even when it was disabled in the Preferences

Updates for version 5.6.0

Area	Description	Notes
Server Load	New feature: the Server load tab has been redesigned and the log file fetching mechanism works in the same way as in the Timeline tab (documentation is available here). Please note that at the same time the standalone Server load viewer was removed from ecFlowUI.
Timeline	New feature: added combo box to the duration view mode in the Timeline panel to control what duration is actually shown. There are these two options now: First duration in period (valid for the first submitted and active duration pair in the currently selected period) Mean duration (valid for the whole log period) Please note that Mean duration is a newly added option.
Timeline	New feature: the dialog showing the task details now opens up in non-blocking mode
Node Context Menu	New feature: the Set complete and Set aborted actions are now available on suspended nodes
Search	Fix: fixed an issue when selecting an item in the search result view caused a crash
Output log	Fix: fixed an issue when the text view in the output tab did not scroll automatically to relevant keywords (e.g. aborted)

Updates for version 5.5.2

Updates for version 5.5.0

Area	Description	Notes
Date and time attributes	Improvement: there are more details displayed about date and time attributes in the Tree view and Info panel.
Log output	Improvement: when the text filter is used in the Log output panel the number of matching lines are displayed next to the filter expression widget. By default this feature is disabled, it can be enabled in Tools → Preferences → Appearance → Other.
Info panel	Improvement: it is now possible to hide the text labels on the main Info panel tabs and show only the icon decorations. This option is disabled by default, it can be enabled via Tools → Preferences → Appearance → Other.
Info panel	Improvement: context menu for multiple selection now works both in the Node log and Server log info panel tabs.
Context menu	Improvement: when a shell command is run from the context menu and either stdout or stderr is generated a popup window appears showing the shell output and the shell command history. This windows can now be prevented from popping up by using the options added to Tools → Preferences → Menus→ Shell commands. By default the window appears for both stdout and stderr output.
Tree view	Fix: fixed an issue when the 'clock' icon on a node incorrectly showed whether the node has any holding time dependencies
Info panel	Fix: fixed an issue when the icon pixmap on the close button of the Info panel was not visible.
Manage servers dialog	Fix: fixed an issue when ticking the Use ssh option on the edit server dialog caused a crash
Context menu	Fix: fixed an issue when the Shell command history dialog always appeared after running a shell command form the node context menu (it should have only appeared when stdout or stderr were generated).

Updates for version 5.4.0

Area	Description	Notes
Triggers	New feature: the Triggers tab in the info panel now contains a new view showing the dependencies between nodes in a graph layout. The algorithm to generate the graph is the same that was used in ecflowview. The type of the connections between the nodes/attributes are indicated by the line colours. The possible connector types are as follows: direct trigger (black) trigger via dependency (blue) parent child relationship (red) The line colours and some other properties can be changed from Tools → Preferences → Appearance → Triggers:
Tree view	Improvement: allows moving suites within the same server using the plug command in the context menu (implemented via Special → Mark for move and Special→ Move marked node here ). The moved suite is inserted before the target one.
Startup	ecFlowUI 5 uses a different config directory to ecFlowUI 4. If this directory does not exist it is automatically created using the contents of an existing ecflowUI 4 configuration. From this version on the session description is not copied over from version 4. As a result ecflowUI will start afresh showing an empty tree on first start up.
Output log	Fix: fixed an issue when the env variable HTTP_PROXY was mistakenly used in getting the output log from a log server
Triggers	Fix: fixed an issue when the trigger view did not show some limits with relative paths

Updates for version 5.3.1

Area	Description
Servers	Fix: fixed an issue when loading an unavailable server caused a crash
Manage servers dialog	Fix: fixed an issue when after changing a server host or port the server became unavailable on next load (the port number was incorrectly set as the remote user id and this blocked the communication).

Statusbar clock

Fix: fixed an issue when the clock in the statusbar could not be hidden

Updates for version 5.2.3

Area

Description

Startup

From this version ecFlowUI will use a different config directory to enable the clear separation of ecFlow4 and ecflow5 related settings!

In the pre-5.2.3 versions the config settings were stored by default in

${HOME}/.ecflow_ui

From this version on the setting will be stored in

${HOME}/.ecflow_ui_v5

If this directory does not exist yet and we start ecFlowUI without the -confd option a new config directory will be created by copying the contents of the old config directory.

Tools → Preferences → Appearance → Node Labels.

By default the Default style is used (the other ones are disabled).

Icons/flags

New feature: new icons representing server log and checkpoint file error flags were added to the tree/table views. At the same time the meaning of the 'slow disk write' icon changed. The table below gives details about all these icons (available on servers only) :

Description	Associated flag	How to clear flag from context menu?
Error in opening/writing to log	LOG_ERROR	Special → Clear log error flag

To add a variable column use the "V+" icon in the table view control panel. Alternatively variables can be added to the table from the Variables panel's context menu:
Tree view	New feature: Leaf nodes can be automatically expanded when clicking on the parent node. This feature can be turned on/off in Tools → Preferences → Appearance → Tree view using option: Automatically expand leaf nodes. By default this option is off.
Node icons	Improvement: The clock icon can now distinguish two kinds of time dependencies: holding and non-holding ones. In holding mode, when there is an active cron, time or today attribute set on the node the clock icon appears with a white face. In non-holding mode, when the time attributes are defined but not active the face of the clock in the icon is yellow.
Context menu	New feature: A new action called URL command was added to the Special submenu. This action executes the command (via the shell) defined by the ECF_URL_COMMAND ecflow variable of the given node.
Context menu	New feature: The visibility of the Defstatus node context menu in the various menu modes (User, Operator or Administrator) can now be controlled via Tools → Preferences → Menus using option: Node context menu control. By default the Defstatus menu appears in all menu nodes.
About dialog	New feature: the paths to the ecFlowUI log files are now displayed in the About dialog

Updates for version 4.10.0

Installation date 2018-07-10

Area	Description	Notes
Server load	Experimental feature: a new info panel tab called Server Load was added to display various diagnostics about the given server. Note that this module will only be built if the installed version of Qt has the QtCharts component.
Table view	New feature: When a new table view is added the Table Filter dialog automatically appears so that the table filter could be defined before the actual table data is loaded. This can result in much faster initial loading of the table view. This feature can be turned on/off in Tools → Preferences → Appearance → Table view using option: Popup filter dialog when new table view is added. By default this option is on.
Table view	Improvement: The first column in the table view (node path) is sorted by the node index in the given tree instead of the path string itself. This significantly speeds up the table view.
Panels	Improvement: The Suites, Zombies, Server Settings and Server Load info panels, which belong to a given server, are now always visible whichever child node of the given server is selected. Previously these tabs were only visible when a sever node was selected.
Commands	Improvement: when a command sent to a given server fails, the server state is automatically refreshed
Node log	Improvement: added horizontal scroll bar to node log panel

Updates for version 4.9.0

Installation date 2018-04-05 (version 4.9.0)

	Description	Notes
Output log	New feature: if an output file has the extension "`.html`" it will be rendered as HTML. Note that only static HTML is supported, not JavaScript.	Example output with an HTML table
Server sync	Improvement: to further reduce polling commands sent to busy servers, the default behaviour of ecFlowUI is now to increase the sync drift interval at 1.4 times its previous value after each sync. This behaviour is configurable, both globally and per-server from the Server Settings dialog.
Server sync	Improvement: ecFlowUI now drops all its handles with a server when it resets its communication with that server, thus avoiding the accumulation of client handles on the server
Suite filter	Improvement: ecFlowUI now saves its suite filter settings as soon as they are changed (previously they were only saved on closedown)
Tree view	Improvement: when an alias is removed, the selection no longer jumps to the top node
Tree view	Fix: fixed issue where a time icon could be shown on nodes that did not have time attributes
Main UI	Fix: fixed issue where the user interface could hang when trying to write its settings to an erroneously locked settings file
	See also below for more improvements in version 4.9.0

Installation date 2018-02-16 (version 4.9.0)

	Description	Notes
Log output	New feature: a text filter interface was added to the Output panel. It can be controlled via these buttons: The first button makes the text filter bar visible, while the second one shows the context menu of the text filter. The text filter is defined by a regular expression and runs the UNIX grep command to perform the actual filtering of the output file. It can be used in two modes: match: in this mode only the lines matching the regular expression are shown no match: in this mode only the lines not matching the regular expression are shown To run the filter type in the regular expression into the text line editor and press enter. When there are marching lines in the output the regular expression editor and the filter icon turn green otherwise they turn red. To clear the filter just clear the regular expression editor or choose the Clear filter action from the context menu. The filter remains active when switching between output files and selecting new nodes. The actual filter can be saved and then loaded using the filter context menu. To manage the saved filters start up the Text Filter Manager dialog from the context menu.

Notifications

New feature: A new option was added to control the notification popup dialog (in Tools → Preferences → Notifications) as:

Switch to parent's virtual desktop from popup dialog

Having this option enabled if we click on a node in the notification popup dialog the window manager automatically switches to the virtual desktop where the main ecFlowUI window is located and moves the popup dialog into this desktop. By default this option is disabled.

Notifications

Improvement: Colours are available again to decorate the notification interface. The colour selected for a notification type (in Tools → Preferences → Notifications) is used in the following way:

the button in the notification statusbar is only coloured when there are notifications available in the given category
in the notification popup dialog a coloured label shows the name of the given notification category above the list of tasks

For the "aborted" notifications by default the notification background and text colours are automatically taken from the settings of the aborted status itself. This can be overridden form Tools → Preferences → Notifications → Aborted via the "Use aborted status colour" option. When this option is unticked we can set our own custom colours for the "aborted" notifications.

Triggers	New feature: the Triggers panel was completely redesigned to display a table-based representation of triggers. See Viewing dependencies
Refresh	New feature: the refresh server button in the left hand side of the toolbar was turned into a more advanced widget providing better interaction with and more details of the refresh process of the selected server. The new interface comprises the following components (from left to right): refresh button label with the server name progress bar showing the countdown to the next automatic refresh. It also displays the total length of the current refresh period, and the current length of the drift if it is active for this server label showing the time (in local time) of the last server refresh (hidden by default in automatic refresh mode) The properties of this widget (e.g. the visibility of the last refresh time) can be controlled from the dialog in Tools → Preferences → Appearance → Toolbar
Context menu	New feature: a menu mode was added to control which commands are actually shown in the node context menu. The menu mode has these three categories: User (default) Operator Administrator The User mode allows most operations, but for safety prevents certain actions on suites and servers. The Operator and Administrator modes allow suites to be begun, nodes to be removed and servers to be unlocked. Administrator mode additionally enables the Force and Order menus. The current menu mode is displayed in the window title bar of ecFlowUI. To change the menu mode use: Tools → Preferences → Menus → Toolbar
Suite filter	New feature: the Filter only this suite action was added to the Special menu of the node context menu in the Tree view. This action automatically redefines the suite filter on the current server to filter only the suite of the selected node. To view other suites again, edit the suite filter.

Description

Notes

Tree view

New feature: a new tree view layout called 'Compact' is now available. This 'Compact' layout works exactly in the same way as the tree view in ecflowview and saves some vertical space. To switch between the original layout, now called 'Standard' layout, and the new one use Edit → Preferences → Appearance → Tree view → Tree layout style.

Panels

New feature: to help with smaller displays, a new button was added to the panel headers (tree view, table view and info panel) to maximise the panel area. When this button is pressed the panel occupies all the available space in the given tab and the other panels become hidden. At the same time a warning message appears in the header saying "Panel maximised". By pressing the button again the original panel layout in the tab is restored.

Breadcrumbs

New feature: the breadcrumbs are now located in the panel header, saving some vertical space (previously they had their own area just below the panel header). When "Breadcrumbs" is on (toggle via the cogwheel icon) the breadcrumbs are visible in the header, otherwise the node path is simply shown as text.

Why panel

New feature: the top-down Why (through the children) is now displayed in the Why info panel alongside with the bottom-up Why (through the parents). As an additional improvement the node statuses are now colour-coded and the parts of the expression which are false are highlighted (with a darker background). Also, the attribute notation became clearer and both the nodes and attributes are now hyper-linked.

Limits

New feature: the limit editor now shows the list of nodes consuming the given limit. With the provided buttons the selected node paths can be removed ('Remove' button) or the whole list can be cleared ('Reset' button).

Limits

New feature: it is now possible to choose between circular and rectangular limit shapes (see Edit → Preferences → Appearance → Attributes → Limit shape). The default limit shape is "circle". The rectangular shape allows for a more compact view.

Triggers

New feature: the colours used for trigger and complete rendering can now be controlled from Edit → Preferences → Appearance → Attributes.

Info panel

New feature: the 'Info', 'Manual', 'Script' and 'Job' Info panels can now be manually refreshed with the provided button

Info panel

New feature: the "detached" state in the popup (i.e. dialog) info panel is now represented with a separate "chain" button just like in the docked info panel. As a further improvement the "detached" option is saved for the popup info panel.

Info Panel

New feature: flags of the selected node are now displayed in the 'Info' info panel

Tree view

New feature: the last selected node per tree view is saved on exit and restored on startup

Icons

Change: some of the node icons were improved, the changes are summarised below:

Previous	Current	Description
		Node has had a user action since its last requeue (see the Node Log for details)
		Complete by default status or by complete expression
		Has been restarted
		Slow server write

Table view

Change: when a selection is broadcast to the table view (e.g. from a tree view, search result view etc) it will only be visible there if it matches the filter set on the table view. The previous behaviour was that the broadcast selection was always shown in the table view even if it did not match the filter.

Output log

Change: line numbers are no longer shown in the output log ('Output' panel) to save space. Line numbers are still shown for the Script and Job.

Repeats

Improvement: in the repeat editor the current value for date repeats can be selected from the list at the bottom of the editor

Command

Improvement: when a command sent to the server fails, a dialog pops up showing the error message

Context menu

Improvement: the 'Cancel' command was renamed 'Remove' and was made available for suites, tasks and families

Context menu

Improvement: the context menu now better handles the situation where multiple nodes and attributes are selected

Limits

Fix: fixed issue when the limit text was incorrectly turned red when the limit reached, but did not exceed, its maximum

Limits

Fix: fixed issue when the limit maximum could not be set to zero

Context menu

Fix: fixed issue when stray context menu appeared in panel headers

Update

Fix: fixed issue when setting the server update frequency did not always make effect immediately

Server list file

Fix: fixed issue when a malformed server list file caused a crash

Zombies

Fix: fixed issue when commands did not work for multiple zombie selection in the Zombies info panel

Variables

Fix: fixed issue when deleting a variable caused a crash

Stability

Fix: fixed additional crashes

Updates for version 4.5.0

Installation date 2017-01-10

Area	Description	Issue
Nodes	Improvement: tree and table views will now always show the selected node, even if it does not match the filtering criteria. For example, if a tree view has a status filter which does not display completed nodes, and the user clicks on a completed node from a search result or a notification, then it will appear in any tree or table view that is in the linked state.	ECFLOW-813
Tree view	Improvement: when the result of a search is an attribute and it is clicked on, it becomes selected in any linked tree views	ECFLOW-839
Variables panel	Improvement: the variables panel now has a horizontal scrollbar, allowing the easy viewing of long variables	ECFLOW-830
Shutdown	Fix: fixed occasional crash on shutdown	ECFLOW-832

Variables	Fix: fixed issue where the "Add variable" button was disabled in the Variables panel
Tree	Fix: fixed issue where the "Order top/bottom" command did not work for suites in the tree view

Installation date 2016-09-26

Area	Description	Notes
Trigger view	New feature: a new tab called "Triggers" was added to the Info panel. It displays a list-based trigger dependency view. See Viewing dependencies - 2016
Triggers	New feature: triggers can now be edited by either double-click on them or selecting "Edit ..." from their context menu.
Server List	New feature: ecFlowUI now updates its local server list with the centrally maintained system server list on every startup. See Server management
Migrate/restore	New feature: The Migrate and Restore commands are now available for suites and families from the Special context menu. Besides, a new icon representing the "Migrated" flag was added to the tree and table views. This is ON by default. This can be set from the Icons menu from the header of the tree view panel. Please note that this feature will only work with servers running ecFlow version 4.4 or above.
Why panel	New feature: Node paths appearing in the Why panel are now hyperlinked. Clicking a hyperlink results in broadcasting the selection to the other views (tree/table).
Info panel	New feature: If an "aborted reason" is available for a node its full text is displayed in the "Info" tab in the info panel.
Limits	Improvement: if a limit exceeds its maximum value the values beyond the maximum are rendered with a different colour (blue by default). This colour can be customised in Preferences → Appearance → Attributes → Limit exceed colour. As a warning, when the value exceeds the maximum the numbers for the limit value and maximum value are rendered in red.
Table view	Improvement: the table view now remembers the width and the visibility of the table columns.
Table view	Fix: fixed issue when the node status was always rendered with gradient shading in the table view. It now respects the setting in Preferences → Appearance → Status → Status rendering option.
Node search	New feature: a "Clear options" button was added to the Node search dialog to clear the query options set for the nodes and attributes.
Icons	Improvement: the icon pixmaps are now displayed in the Show icon menu (in the header of tree view panel).
Configuration	Fix: fixed issue when window geometry and layout was incorrectly saved

Updates for version 4.3.0

Installation date 2016-08-25

Area	Description	Notes
ecFlowUI	Improvement: the way in which node selections are propagated between different panels has been clarified. Now, there is a 'link' icon at the top-right of every panel. When this is solid, it means that this panel will respond to node selections in the other panels. For example, if an Info Panel is linked, selecting a node in any Tree View or Table View in that tab will cause the contents of the Info Panel to be updated for that node. If it is 'unlinked', then its contents will not change when nodes are clicked in different panels. This latter state is what used to be called 'detached'.
Tree view	Improvement: the status filter has been redesigned to avoid confusion. A status' visibility is always clearly shown in the filter (highlighted with shading), with "Show all" and "Hide all" buttons
Info panel	Improvement: it is now possible to view the output for queued and submitted jobs, but with a message to warn that they may not be current
Suite filter	Improvement: the suites in the suite filter are now listed alphabetically
Suite filter	Improvement: ecFlowUI now allows an empty suite filter
Info panel	Improvement: if it is not possible to retrieve a directory listing for the job output files, a warning message is displayed with the reason why
Custom commands	Fix: fixed crash when a custom command required further input from the user; a pop-up message will now appear
Table view	Fix: fixed issue in the Table View where navigating the nodes with the keyboard did not update the node displayed in the Info Panel
Info panel	Fix: fixed an inefficiency in retrieving the job output files and scripts when the log server does not return anything

Tree View	Fix: fixed issue where changes in node order were not reflected in the tree

Installation date 2016-07-26

Area	Description	Notes
Version	Note that you need to load the 'dev' module of ecflow to get the 4.3.0 test version: module swap ecflow/dev ecflow_ui
Startup	New feature: Added new command-line option to start up a temporary session showing the given server. Usage: ecflow_ui -ts <host> <port> On closure, the session can be optionally saved or discarded. To see the list of saved sessions, start ecFlowUI with the session manager: ecflow_ui -s
Suite filter	Improvement: the interface to the suite filter has been redesigned for greater clarity.
Suite filter	Fix: Fixed issue where clicking 'Unselect All' broke the suite filter if it contained unloaded suites.
Output log	New feature: the initial search conducted on an output log is now configurable from the Preferences dialog in the Edit menu.
Output log	Fix: fixed issue where output from the wrong output log file could sometimes be displayed if the logs are larger than 1MB and are retrieved from the server rather than being read from local disk.
Output log	Fix: fixed issue where a regexp search on large output log files did not work
Output log	Fix: fixed issue where clicking inside the scrollbar area of the output log viewer could scroll more lines than one page, meaning that lines could be missed if using this mechanism to scan through a log file
Node actions	Fix: fixed issue where clicking on the context menu's title (showing the node selection) caused the first action in the menu to be executed on the selected nodes. Clicking here now performs no action.
Node actions	Improvement: ecFlowUI syncs with the server immediately after issuing a command to it. Previously there was a delay.
Edit panel	Fix: fixed issue where an error in a script was not shown to the user, for example when an ecFlow variable is used but not defined. Now a panel is displayed in this case, showing the message from the server.
Refresh	Improvement: reduced the number of duplicated Refresh buttons in the user interface, as they could cause confusion. To refresh/sync with a server, use the green refresh button at the top-left of the window (shortcut: F5). The Refresh menu offers more options.
Testing	New feature: a new script has been added in order to allow installers to quickly check that ecFlowUI is working. It will start a local ecFlow server, load a suite and launch ecFlowUI in a temporary session to view the test server. The script is installed with ecFlow, and is run like this: ecflow_test_ui.sh

Installation date 2016-06-30

Area	Description	Notes
Attribute search	New feature: the search dialog was extended and is now also capable of finding attributes. See Searching for nodes.
Tabs	Improvement: the title of the tabs in the main interface is now automatically adjusted to the available space. When a lot of tabs are open it makes the navigation easier. The way the tab title is drawn has also been changed and the close button was removed from the current tab. To close a tab right-click on a tab and select "Close tab" from the menu.
Tabs	New feature: to improve the tab navigation a new button () was added to the right edge of the main tab bar. By pressing it the list of the open tabs appears in a drop down menu with the current tab being highlighted in bold.
Icons	New feature: a new icon representing the "Killed" flag was added to the tree and table views. This is OFF by default. This can be set from the Icons menu from the header of the tree view panel.
Tree view	Fix: fixed issue where the tree was not expanded on node lookup
Tree view	Fix: fixed issue where the default node status was incorrectly displayed in the node tooltip
Breadcrumbs	Fix: fixed issue where the server status was not updated in the breadcrumbs
Output panel	Improvement: the column-width of the list of available output files are automatically adjusted to their contents when the output panel is first loaded.
Output panel	Improvement: a failed text search will no longer put the cursor to the top of the output file
Documentation	New page: Viewing and editing variables

Updates for version 4.1.0

Installation date 2016-05-11

Area	Description	Notes
Startup	New feature: ecFlowUI now supports the notion of multiple sessions so that different configurations can be stored. See Session management for more information.
Variables panel	New feature: The Variables panel can now distinguish and filter the shadowed variables. A variable is called 'shadowed' if it is redefined later in the node hierarchy. For example, it could be defined at the family level, and then again in a task within that family; in this case, the variable defined in the family is 'shadowed' by the one in the task and will not be used. Shadowed variables are displayed in grey. They can be shown/hidden with the 'VV' button in the Variables panel. By default shadowed variables are visible in the panel.
Variables panel	Improvement: the add, edit and delete variable actions are always applied to the node selected in the Info Panel (i.e. the topmost node in the Variables panel), even if they are inherited from an ancestor node.
Info panel	Fix: fixed issue where selecting a node in the breadcrumbs of a non-detached Info panel did not result in selecting the same node in the tree view
Output panel	Improvement: the list of available output files is now refreshed when the Reload button in the Output panel is clicked.
Tree view	Improvement: improved rendering for limits
Tree view	Improvement: improved rendering for number of children displayed next to servers and nodes
Tree view	New feature: the tooltip shown in the tree view can now be enabled/disabled through the configuration dialog (Edit -> Preferences -> Appearance -> Tree view). By default the tooltip is enabled for servers, nodes and attributes.
Exit	New feature: no confirmation dialog pops up on exit. However, a confirmation dialog is still shown if there are multiple windows open and a window with multiple tabs are to close.

Attributes	New feature: labels, events, meters, limits and repeats appearing in the tree view can now be edited. Usage: Events can be changed using the "Set" and "Clear" context menu actions Labels, meters, limits and repeats have their own editor that can be started up by either double-click or using the Edit action from the context menu.
Attributes	New feature: a tooltip is available for all the attributes displayed in the tree view
Attributes	New feature: some graphical features of the attributes can be configured from the attributes setting dialog (Edit -> Preferences -> Appearance -> Attribute).
Meters	New feature: the threshold of a meter is now displayed in the meter progress bar. Normally the meter progress bar is drawn only with one colour but if the meter value exceeds its threshold the progress bar changes colour from that value onwards. Both the meter colour and the meter threshold colour can be defined in the configuration dialog mentioned above.
Completes	New feature: the complete attribute now appears in the tree view when "Triggers" are selected in the Show attributes menu. The visual representation of completes is the same as for triggers but the text colour is blue instead of black.
Notifications	New feature: clicking on a node in the Notifications result dialog will automatically select the same node in the first tree view where it is available
Search	Fix: fixed issue where the Info panel dialogs could not be started up from node search list context menu
Tree view	Fix: fixed issue where removing and adding back a server to the tree view caused random crashes

Tree view	New feature: added an option to draw the branch lines between the nodes in the tree view. This feature can be controlled from the configuration dialog (Edit -> Preferences -> Appearance -> Tree view). By default this feature is disabled.
Tree view	Fix: fixed issue where updating a tree view with a node status filter enabled caused random crashes
Configuration	Fix: fixed issue where setting font sizes in the configuration menu caused a crash.
Logging	Improvement: Log messages are no longer sent to standard output by default, but are written to a log file under `$TMPDIR`. In the event of an unexpected exit, the last part of this file, along with a backtrace if available, will be sent to the developers. To bypass this behaviour and to see the log messages as they are generated, start ecflow_ui with the `-log` option. Note that the startup script `ecflow_ui_bt` is deprecated, as the backtrace functionality is now built into the main startup script.

Update	New feature: added options to gradually increase server update period when the user does not ask for updates manually. It can help to avoid overloading busy servers. This feature can be controlled from the server setting dialog (Edit -> Preferences -> Server options). Usage: When option Increase server update period when inactive is enabled the server update period is increased at every automatic update until the maximum period is reached. If the user in the meantime updates the server manually the update period is set back to its original value and whole process starts again. Option Server update period increment defines the update period increment in seconds Option Do not increase server update period over defines the maximum update period in minutes. By default this feature is enabled.
Output logs	New feature: a new button was added to the Output panel. By clicking on it a popup window shows detailed information about the output log file shown in the panel.
Generated variables	New feature: generated variables are now clearly distinguishable from user variables in the Variables panel. They have a green colour and an icon decoration (with letter 'G' in it).

Installation date 2016-02-18

Area	Description	Notes
Managing large output files	New feature: large output files are now displayed much faster requiring far less memory than before. Although the output text viewer looks and behaves the same for all file sizes internally ecFlowUI uses a newly developed text editor for files larger than 5 MB.
	New feature: when an output file is transferred from the logserver a progress bar is shown indicating the current status of the file transfer.
	New feature: output files transferred from the logserver are cached. The cache holds a file for two minutes starting from the moment the file is unloaded from the viewer (we select another output file or click on another node). If we view the output file within these two minutes ecFlowUI will use the cache and will not transfer the file again from the logserver. However if we click on the Refresh button the cache is bypassed and the latest version of the current output file is fetched from the logserver.
	New feature: for improved efficiency, when viewing output files larger than 5 MB the text search works in "confirm" mode where the search is only initiated when `Enter` is hit or one of the search arrows is pressed. For files smaller than this size the search is still instantaneous (it is initiated as we type in the text). The "confirm" mode is clearly indicated by a message bar above the text search panel.
Display node type in the tree view	New feature: the type of the nodes can now be displayed in the tree view. Each type is represented by its first character as follows: S: suite F: family T: task A: alias A different visual representation is used for the "Classic view" and the "Modern View". In "Classic view" the node type is drawn to the left of the node rectangle into a separate box, while in "Modern view" the node type is drawn straight into the status box. This feature can be switched on/off in the Configure dialog (Edit -> Preferences -> Appearance ->Tree view -> Display node type), the default setting is on.
Output tab preserves its content	Improvement: the Output tab now preserves its content: if we click on another tab in the Info panel and click back to the Output tab it does not need to reload the file.
Custom command	Improvement: the node context menu shows the last 10 custom commands that were run. See Creating and running custom commands for more details.
Context menu	Improvement:the 'Special' submenu has been re-added to the node context menu

Installation date 2016-01-20

Area	Description	Notes
Expand/collapse nodes in tree	New feature: the node context menu in the tree view now contains the "Expand all children" and "Collapse all children" actions to expand/collapse the sub-tree below the given node.
Abort text	New feature: ecflow allows an abort to pass a string (possibly containing instructions on how to fix the abort etc.). This string is displayed now next to an aborted node in the tree view using the same text colour as the aborted status. The abort string might be clipped if it is too long, but the node tooltip always shows the whole string.
Copy node path	New feature: the node context menu now has an action to copy the node path (or a list of paths for multiple selection) to the clipboard.
Icons	New feature: Some of the icon names and icon pixmaps were changed. Changes in the node icons: The icon previously named "Messages" was renamed as "Has node log entry" and its pixmap was changed to: Changes in the Info panel tab icons: The Manual tab's icon was changed to: The Output tab's icon was changed to: The Server log tab's icon was changed to: The tab previously called "Messages" was renamed "Node log" and its icon was changed to:
Custom command	Improvement: it is possible to run your own custom commands on nodes - select a set of nodes, then choose Custom... from the context menu. The improved custom command editor now presents a list of the available ecflow client commands, along with the help pages for each. Remember to put the <full_name> tag at the end of the command - this will be replaced with the list of selected nodes. The ability to save and load custom commands, and to add them to the context menu will be available in a later version.
Node tooltip	Improvement: the node tooltip in the tree view now contains the description of the icons of the node. The tooltip also shows the abort text if it is available.
Manual	Fix: fixed issue where the manual was not shown.
Info panel	Fix: fixed issue where the info panel dialog always stayed on top of the main window and could not be be properly minimised.
Server log	Fix: fixed issue where the server log crashed for local log files.
Context menu	Fix: fixed issue where certain menu options depending on the server state did not work.

Installation date 2015-12-09

Area	Description	Notes
Text search	New feature: all found occurrences of the search term can be highlighted. This option is OFF by default as it can be expensive with very large log files. Activate from the search options control, or press ALT-A to toggle.
Output logs	Improvement: logs served by a log server are now transferred asynchronously, allowing the user interface to respond during that time. Note that there can still be a delay in displaying large log files (say > 30MB) - solutions to this are being evaluated, but some improvement has already been made.
Windows	Improvement: the current configuration of tabs and windows, along with their loaded servers, is now saved whenever the set of loaded servers is modified.
Node search	Fix: fixed issue where constructing a search with both a node name and a node path caused a crash.
Info Panel	Fix: fixed issue where the info panel could not be reduced to a small horizontal size due to the length of the file info panel at the top.

Installation date 2015-12-03

Area	Description	Notes
Font	New feature: fonts are now customisable for the tree view, the table view and for the text browsers/editors in the Info Panel tabs.The font family and size can be changed through the Edit -> Preferences -> Fonts dialog. For the text browsers/editors in the Info panel tabs the text size can be changed directly by either using Ctrl+wheel or the Increase/Decrease font size buttons in the tabs.
Tree and table view background	New feature: These background colours can now be customised via Edit -> Preferences -> Appearance ->Tree view and Table View.
List of attributes shown in a tree view.	New feature: By default all the attributes except the variables and generated variables are shown in a newly created tree view. This default list can be changed in Edit -> Preferences -> Tree view.
