Sugar Calendar vs ZenTao: editorial side-by-side
Sugar Calendar stops being a second copy of your schedule, with two-way Google sync.
◆ Current state
Sugar Calendar Events now syncs with a chosen Google calendar in either direction, or both, and adds Google Meet links to the event editor. Deleted Google events move to the Trash on the site rather than disappearing. Days earlier it added Gia AI, a chat that turns a sentence into a draft event, edits existing events and reports on registrations.
◆ Where it's heading
The plugin's sweep of manual work around an event has moved from attendee tasks to event creation itself. Both October releases remove double entry: Gia parses a description into fields, and Google sync removes the second calendar. Each post is still a how-to rather than a release note, with versions left unstated.
◆ Prediction
Attendee answers and registration data remain the obvious material for Gia, which can already report on registrations. The posts do not say whether Outlook or other calendars will follow Google.
ZenTao
2.5PM
ZenTao posts a 22.0 beta with no notes in the feed.
◆ Current state
The only tracked ZenTao entry is the 22.0 beta tag from October 21. It links to a changelog file in the repository and contains no description of what changed.
◆ Where it's heading
A beta of a new major version suggests a larger release is in progress, but nothing in the feed says what it contains.
◆ Prediction
Unclear: the entry does not show what 22.0 changes or when a stable version will follow.
