Changelog

10.5.4 (2026-11-15)

• (@GermanBluefox) Function block diagrams: a STATE_OUT is no longer shown as deviating when the state holds the value with float precision only (#2461)

10.5.3 (2026-11-11)

• (@GermanBluefox) Fixed: the cursor of the script editor jumped to the start of the script after the first typed character (when nothing else had updated the editor since the script was opened) and after saving

10.5.2 (2026-11-11)

• (@GermanBluefox) Added: function block diagrams - the online view marks a STATE_OUT block whose state somebody else changed (VIS, another script, by hand) and shows the value the state holds; the new option "Write the value back" of STATE_OUT writes the value of the diagram back then, at most once a second (#2442)
• (@Voodoo2man) Added: Blockly category selection for member IDs and change/ack filters to the enum trigger (#1960)

10.5.1 (2026-11-10)

• (@GermanBluefox) Added: function block diagrams - blocks can be pinned (pin button on the block, its menu or the properties): "Arrange automatically" leaves them where they are and arranges the other blocks around them (#2443)
• (@GermanBluefox) Added: function block diagrams - a link can be moved to another input by dragging its connected input; let go where no input is, it is deleted - a mere click on it keeps it (#2438)
• (@GermanBluefox) Added: function block diagrams - the PID block has the output RUN: TRUE while the controller works, i.e. none of MAN, RST and HOLD is active (#2440)
• (@GermanBluefox) Changed: function block diagrams - the online view shows the value of a link that is not BOOL at the input of the target block instead of in the middle of the link (#2444)

10.5.0 (2026-11-07)

• (@GermanBluefox) Added: script functions readDir, fileExists, chmodFile and chownFile for files in the DB, and chmodObject and chownObject to change the access rights and the owner of objects and states (only with the option "Enable command setObject"), each with an ...Async variant
• (@GermanBluefox) Added: function block diagrams - block CHARCURVE (characteristic curve, e.g. a heating curve): OUT on the straight lines through 2 to 10 points X1/Y1 ... Xn/Yn, kept at the Y of the outer points beyond them; the points are inputs, so they can be connected too, and the properties show the curve (#2433)
