complete restructuring, improvement and addition of the OpenSCADA libraries in the SQLite files;
general documentation enhancements, appending for the all libraries documentation and revision for most module documentation.

- FIX:ElFigure: The mirroring support is completed in the implementing for the common, shape Arc draw and it generic and image fills. The filling by image prevented from lacks at accessing outside the image.
- FIX:Diagram:
  - FIX:Trends: Expanded in the time scale building for many days with the time complete hiding and show the first value in the left, using the timezone offset. Appended for support the big time range intervals per month.
  - Disabled in limiting the requested archive values precision, for long counters.
  - Improved in the remote work on slow channels and with the value buffers period in 10 seconds.
- Text,Media,Box: Expanded to display the activity cursor.
- FormEl: Some views (Line edit, Text edit, Combo box, List, Tree, Table) expanded for custom background and border by the visualiser specific attributes "vs_background", "vs_border".
- Appended for the visualiser specific attribute "vs_winTitle" of the dynamic window title value.
FIX:Vision:
- Optimisation the remote development:
  - The projects tree switched to download the branches partially at expanding, to improve it work on slow connections.
  - The widgets tree improved in the work on slow connections, disabling the widgets' icons downloading at the threshold of the complete tree downloading time more for 5 seconds and enabling that at the time less for 0.1 second.
- Expanded for the planning of the updating period depending to the real connection quality of the runtime mode, like to UI.WebVision.
- FIX: Common fixes and improvements of the runtime window modes:
  - FIX: Manual scaling of the runtime window (for full-screen or maximise) improved and fixed in the processing the sign isResizeManual.
  - FIX: Fixed in starting to the full-screen mode and not full scaling at restoring to not zero window position.
- FIX:FormEl:
  - FIX:Table: Tables fitting improved to use maximum width from the widget size and the maximum view port, but the maximum view port only can be uninitiated here yet. Final fix for the tables fitting, moving the procedure in events: create, resize and show. Prevented from casual crashing.
  - FIX:Date: Fixed for crashing at setting configuration.
- FIX: Fixed for the master page regular replacing (crashing) and scaling into the run-time mode.
- FIX: The runtime executing was fixed from crashing in closing external windows at closing the main window.
- FIX: Fixed in the properties edition dialogues of Pages/Libraries and Widgets for:
  - preventing for closing at Esc;
  - disabling for timeouted cancelling of the LineEdit;
  - unbinding the edited state from the visibility for TextEdit;
  - preventing from the changes loss into the tab "Process";
  - appending for warnings about the inherited calculation procedure changing.
- The focus control rewrote to the VCA-widgets specific one and not Qt-widgets, like to UI.WebVision, what prevents some problems.
- ElFigure: The figure edition switched to the normal mode, without any transformation (rotation and mirroring).
FIX:WebVision:
- FIX:Main operation:
  - FIX: The JS function servSet() of writing to the server switched to the synchronous mode to prevent loses.
  - The main checking of the background objects is made unified and expanded for support the optional background objects, to decrease the overall number of the background objects, where the obligatory currently are: "ElFigure", "Diagram", "Document", "FormEl"; and the optional is only "Text".
  - The main window vertical expanding threshold set to 10% of the window decreasing size and to 50% for shrinking, to prevent flicking on FireFox for notes about block the external windows. The built-in scaling mode set to use-enable in relation from window.devicePixelRatio equal to 1, on the WebBrowser level.
  - Significantly improved in the connection losses detection for the main page reload, for the cases of return back to already closed sessions in WebBrowser.
  - Appended for implementation the visualiser specific attribute "userSetVis".
  - FIX: Restored in the full widgets tree reloading to restore the function of removing missed widgets in the visualiser at their removing into the VCA-engine.
  - FIX: Prevented from spare and separate requesting of the included pages' content, in the starting.
  - FIX: Improved for the focus control behaviour and fixed to prevent mouse events to behind pages.
- Appended for the pages cache be controlled in the lifetime and the pages maximum number, both on the server and WebBrowser side, then the module is more suitable now to work in the operative mode!
- Sessions control:
  - Expanded for the possibility of the opened sessions manual closing from the administrator user.
  - FIX: The ordinal users prevented from connection to foreign sessions.
  - FIX: The main requesting code of GET significantly simplified to prevent of reconnections to the VCA-sessions without the local ones.
  - Appended for the state of the opened sessions on the control page, including the connected project and the user.
- FIX:Status bar:
  - Appended for the alarm level with a function of the global quietation, sending "ws_alarmLev".
  - Expanded for the VCA-styles support in their display and changing.
  - FIX: Fixed in form the statusbar size, updating and preventing from its flicking at the master page updating.
- FIX:FormEl:
  - FIX:{Tree,Table}: Are fixed for true counting the border width and padding in the result geometry.
    - FIX:Tree: Fixed for processing the empty string in the end. Appended for scaling the control tree images.
- Expanded for setting the VCA visual elements at the "class" attribute to "Primitive {WPrimitive}" and the "id" attribute to the widget identifier like to "wdg_{id}", for simplifying the customisation.
FIX:QTStarter: The function updLookFeel() fixed for the void return type. Right mouse key and context menu emulation is added at holding the left mouse key during the time set by the command line option --simulRightMKeyTm. This time set to 2 seconds for Android.
FIX:QTCfg:
- FIX: Fixed for applying forgotten changes of the editable widgets at switching to a different node. The TextEdit items fixed for the editing sate detection, what is unbidden from the visibility.
- The Node groups hint is added for a command of the node adding.
- The moving operations, in the configuration table, expanded by the hot keys "Ctrl+Up" and "Ctrl+Down".
- Optimisation the remote work:
  - Prevented from the navigation tree updating at selecting any item.
  - Makes slower the cycle of the periodic updating after the busy dialog appearing.
- Set fast for the closing time of the configurator window with many OpenSCADA inactive external hosts, by early notifying the host tasks.
WebUser: Expanded by the DAQ-templates support.

10 Special

FIX:FLibSYS:
- FIX:IO: write() fixed for the default data type obtain, wrong data type obtaining set safe.
- CRC: Completed by using normal polynomials, the input and output references and the XOR for output.
- VArchObj: Access to the archive writing functions restricted only for users in the group "Archive".
