7.1.1 (2026-05-18)

New features

- Created an :attr:`~icalendar.prop.dt.period.vPeriod.ical_value` property for the :class:`~icalendar.prop.dt.period.vPeriod` component. @ZairKSM (`Issue [#876](https://github.com/collective/icalendar/issues/876) <https://github.com/collective/icalendar/issues/876>`_)
- Created a :meth:`~icalendar.prop.recur.weekday.vWeekday.ical_value` property for the :class:`~icalendar.prop.recur.weekday.vWeekday` component, mirroring the existing pattern on :class:`~icalendar.prop.boolean.vBoolean`. @mvanhorn (`Issue [#1360](https://github.com/collective/icalendar/issues/1360) <https://github.com/collective/icalendar/issues/1360>`_)
Bug fixes

- Strictly validate BINARY property values in :attr:`vBinary.from_ical() &lt;icalendar.prop.binary.vBinary.from_ical&gt;` and reject malformed Base64 input instead of silently accepting invalid characters. @uwezkhan (`Issue [#1349](https://github.com/collective/icalendar/issues/1349) &lt;https://github.com/collective/icalendar/issues/1349&gt;`_)
