October 25, 2026 (XV4 build 25689)
Improved
•Added the new macro function StrDatesConcatenateEx which extends the functionality and options available in the existing macro function StrDatesConcatenate.
•.Added compilation errors 110204, 110205 and 110206 to prevent the use of spurious or improperly place return instructions in user-defined macro functions.
•The technical support module now exports the current script as XML, converts your InDesign templates and output files to IDML, and gathers temporary data logs, all in one ai.zip package that you can submit all these to an AI assistant, such as ChatGPT, that is able to understand the Q++Studio scripts saved as XML as well as InDesign documents saved as IDML files.
•Added a gateway help topic destined for AI assistants that are reading the Q++Studio documentation, and an extended section describing the details of the XML representation of data structures in Q++Studio, as well as some case examples.
•Removed screen flicker during lengthy operations of the holidays synchronization dialog.
Fixed
•When editing mixed-source tokens, the translations of the parent language would not be displayed (18-oct-2026).
•The macro function FormatTime could apply a double rounding in some rare case, such as when bRoundMinutes was true and the format contained minutes (n/nn) but no seconds (s/ss) and adding another 30 seconds to the internal formatting of time function would not cross midnight (9-oct-2026).
•Some regular expressions in the search dialogs for holidays, saints and slogans, might have been processed in case-sensitive mode despite the expectation that the regular expression was case insensitive (9-oct-2026).
•.Fixed a bug in the 64-bit database server engine that would occur in extremely rare boundary conditions (7-oct-2026).
September 30, 2026 (XV4 build 25589)
New
•Q++Studio's support for all versions of InDesign, from InDesign 2020 to InDesign 2026, now includes tested support for the latest update to InDesign 2026 (version 21.6 of September 10, 2026).
Improved
•The dialog that is used to link one of your holidays to one of the qppstudio worldwide public holidays database holidays, during holidays synchronization, now preselects any target holiday whose rule is the same or similar to that of your source holiday.
•The number of allowed instructions when, using InDesign, has been increased to 1024K.
•You can now specify the observance of a recurring holiday using observance labels within holiday name variations, meaning that different occurrences of the same recurring holiday can have different observances.
•When inside the macros editor, you can now easily see the relationship between any line of source code and the compiled code line(s) that stem from these, and vice-versa, for any line of compiled code you can see the source line it was generated from.
•Added 4 columns to the planetary data export containing the morning and evening planetary visibility according to our approximation to the criteria used in the USNO Astronomical Phenomena and Astronomische Grundlagen publications.
•Improved the scope and efficiency of the macro function GetHolObservanceFromTable.
•In the XML Script Editor, it is now also possible to insert a scriptline as well as replace the currently selected scriptline.
•Improved the calculation of Bhutanese solar calendar holidays, such as the Blessed Rainy Day, by rounding up the calculated date when the fractional solar component is at least 30;60 which matches every official announcement by the Government of Bhutan since 2016.
Fixed
•Fixed borderline cases of lunar visibility for MUIS (Singapore), JAKIM (Malaysia), and MABIMS (Indonesia and Brunei), as well as setting the exact cutoff date when each of these 3 umbrella organizations changed criteria in 2021-2022 (27-sep-2026).
•Some of the positions displayed in the planetary visibilities and astronomical phenomena of the astronomical data export would use geocentric coordinates when the Excel workbook header specified that these were topocentric coordinates (27-sep-2026).
•Fixed a memory leak in the sql query editor of the database querying dialog (26-sep-2026).
•Fixed a latent issue that could cause InDesign diary generation to abort when framing and shading minicalendar dates (Alpha, 25-sep-2026).
•The azimuth in planetary tokens and the planetary data export was south-based rather than the standard north-based azimuth (13-sep-2026).
•Fixed a bug in the implementation of the macro functions GetHolidayText and GetHolTextOverrideFromTable (12-sep-2026).
•Fixed a bug in the macro compiler which would occur when the call to a user defined function.was placed immediately after the equality sign and followed by the addition of another term (7-sep-2026).
•Fixed a boundary-condition bug in the calculation of Bhutanese lunar calendar holidays, such as the Traditional Day of Offerings for the calendar years 2030-2032, when testing possible leap-day or leap-month variants for the first day of the month of Pausa/rgyal (1-sep-2026).
August 31, 2026 (XV4 build 25530)
New

Improved
•Beginning in the summer of 2026, we began what we call “reverse-training” of AI assistants on the Q++Studio documentation ("training" the documentation to work better with AI assistants). As this reverse-training progresses, we will continue to update the topic on using AI assistants with the Q++Studio documentation.
•When using InDesign, text frames that are grouped and then anchored, possibly multiple times, are now processed normally.
Fixed
•Fixed the incorrect occurrence of message 180405 when trying to run Q++Studio on an Azure Virtual Desktop (AVD) which does not identify itself as a desktop version of Windows (Alpha, 9-aug-2026).

Fixed
•Fixed an exceedingly rare error which would occur when trying to edit the begin/end rules of daily scriptlines which had initially been set in early 2022 as a weekly scriptline and later changed to a daily scriptline, in both case referring to ISO week numbers as the basis for the begin/end rule (Lecas, 22-july-2026).
•Messages 186410 and 186415 would be generated spuriously, along with their corrective action (restoring the apply text formatting to option back to Token Only), in all cases where the apply text formatting to option was set to anything other than Token Only or All text in Box/Cell (JMata, 18-July-2026).

•Fixed an issue when trying to apply character or paragraph styles within an InDesign table (9-june-2026).
•Fixed a rarely occurring bug which generated a spurious, but harmless, message 174480 during scanning if a minicalendar was in an InDesign table which was anchored in a box with 9 or more objects anchored before it (4-june-2026).

Fixed
•Added code to prevent future, and fix past, de-synchronization between some of the database tables and their auto-increment fields (JMata, 18-apr-2026).
•Under certain rare circumstances, zap tokens and conditional tokens would not be processed correctly. Namely, when containing conditions with tokens of a different DayValue than that of the zap or conditional token, in backtrack every month templates containing more than one month per page, and referring to DayValues in any month except the first of the page (Finocam, 16-apr-2026).
