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.
