1.5.5

Patch Changes

  • 9603b8d: Update the bundled calendar-link library from 2.11.4 to 2.11.6 and Recharts
    from 3.10.0 to 3.10.1. Calendar exports and the statistics and comparison
    charts show the same dates, values and tooltips as before.

    The Fair Events calendar button now passes all-day events to the calendar
    as plain dates, so they stay on their day in every timezone. Without this,
    the updated library would have moved them one day later for visitors in
    UTC+12 timezones, such as New Zealand in winter or Fiji.

    1.5.4

Patch Changes

  • 0c94b22: Calculate Calendar Button repeat dates the same way Fair Events does. An event that repeats until a chosen date now includes the occurrence that falls on that date, even when it starts later in the day, and the editor’s occurrence calendar marks the right end day in timezones behind UTC. Existing blocks keep their saved repeat rule until the repeat settings are edited.
