Open Planner Studio v2026.7.7

What's New in v2026.7.7

This release delivers phase 2.8b: hour planning — schedule in hours and minutes, plan day and night shifts, and zoom the Gantt down to the hour. It also overhauls date entry throughout the app.

Hour planning (off by default)

• One master switch: hour planning lives behind a single new setting, off by default. Leave it off and the app looks and behaves exactly as before. Files that contain hour data still compute correctly and the app offers to enable the switch — nothing is ever silently rounded.
• Work-time bands: calendars can now carry real working times per weekday — multiple blocks per day (morning + afternoon around a break), night shifts that cross midnight, and true 24/7 calendars where the clock never stops.
• Shift presets: one click sets up Day shift, 2-shift, Night shift or 24/7 — and you can save your own presets. A full per-weekday editor sits behind "Set per weekday…" for anything exotic, showing the derived hours per day as you edit.
• Hours in the schedule: give any task a duration in hours via three synced fields (days, hours, total hours — whole numbers, live-converted through the task's calendar). Tasks on hour calendars start and finish mid-day; a follow-up task can start at 12:00 sharp, and concrete can cure 48 clock-hours through the weekend.
• Hour timescale: zoom in far enough (with the switch on) and the Gantt shows an hour scale; dragging snaps to whole hours, never finer.
• Split task bars: an hour task spanning breaks or nights can show its real work blocks. Choose never / when selected (default) / always in the settings.
• Mixed projects: combine day tasks and hour tasks freely (or disable mixing in the settings). A warning icon on the duration column explains when calendars with different day lengths meet.

Dates: type, don't click

• Native date pickers are gone. Every date field is now a segmented text field (dd | mm | yyyy): type two digits and it jumps to the next segment, paste any common format, press Enter to confirm. Errors only show once you leave the field — never while typing.
• Date notation setting: choose dd-mm-yyyy, mm-dd-yyyy or yyyy-mm-dd and every table, panel, tooltip, report and print follows — including the segment order of the input fields.

Interoperability

• Minute precision end-to-end: Primavera P6 and MS Project files no longer have their hour-level durations rounded to whole days on import — the single biggest data-loss point is gone. Work-time bands, shift calendars and hour durations round-trip through IFC 4.3, P6 XML and MSPDI.
• Day-based files stay byte-identical on round-trip; a file only becomes hour-mode when it genuinely contains sub-day information.

Fixed

• Calendar dialog: Cancel now truly reverts all changes (the dialog works on a buffer until you Apply) and Enter confirms in the calendar dialog and project wizard.
• The "fixed winter break" toggle was removed from the holiday generator — add such periods manually instead; old files load unchanged.
• Opening the per-weekday editor on a standard calendar no longer silently changes its hours per day (the implied lunch break is now materialised as a real gap).
• Various date-field polish: values display as dd-mm-yyyy, clicking a filled segment lets you type over it, and schedule dates on hour tasks carry their time of day.

Quality

• Scheduling regression suite grown from 290 to 319 hand-computed cases plus four dedicated check batteries (date/time substrate 55, hour calendars 92, adapters 38, holidays) — all green, with the 23 example files verified byte-identical.
• All new UI text translated in 14 languages.
