Overview
Concrete tool for verifying release schedules against published calendars provided by verify_release_calendar.py.
Description
The verify_release_calendar.py script fetches the Confluence release plan wiki page and the Google Calendar iCal feed, parses both into structured data (Release and CalendarEntry dataclasses), and cross-references them to identify discrepancies.
Usage
Run before starting any release cycle to validate the schedule.
