### 0.1.0-alpha.1
- First alpha release of the Gravity Forms Google Calendar Add-On.
- Added a feed action that creates a Google Calendar event from a submission, taking its time from mapped Date and Time fields with either a fixed duration or mapped end fields, plus support for all-day events and iCalendar recurrence rules.
- Added a Calendar Event field so visitors can register for events that already exist on a calendar, with capacity counted from Gravity Forms entries, remaining places shown in the choice label, and an optional write-back that adds the registrant to the event as a guest.
- Added a Booking Slot field that offers only times genuinely free on the target calendar, computed from a weekly schedule, date exceptions, and Google's freebusy data across the target and any conflict calendars.
- Added Google Meet link creation, calendar invitations for mapped and fixed guests, and the {googlecalendar_event_link}, {googlecalendar_meet_link}, {googlecalendar_start} and {googlecalendar_end} merge tags.
- Added a filterable Google Calendar column on the entries list, and a Send Test button on the feed.
- Added cancel and reschedule syncing when an entry is edited, trashed, deleted, or its payment refunded, and support for holding event creation until payment is received.
- Added bring-your-own OAuth 2.0 authentication, with an explicit reconnect notice when Google rejects the stored refresh token.
