Sourced from icalendar's changelog.

7.2.2 (2026-07-20)

Documentation

- Fixed duplicate ``vInt.min`` and ``vInt.max`` descriptions in the API reference that caused the Read the Docs build to fail.
7.2.1 (2026-07-20)
Security fixes

• Fixed GHSA-qjcq-q7h7-r74v <https://github.com/collective/icalendar/security/advisories/GHSA-qjcq-q7h7-r74v>_: a crafted REPEAT on a VALARM could exhaust memory or CPU via :attr:Alarm.triggers <icalendar.cal.alarm.Alarm.triggers> and :class:~icalendar.alarms.Alarms. Expansion is now capped at icalendar.config.MAX_ALARM_REPEAT. Its default is 10000. Set to -1 to disable the cap. :class:~icalendar.prop.integer.vInt now also enforces the :rfc:5545 signed 32-bit integer range on parse. @​SashankBhamidi
