What is Leantime?

Leantime swaps role ranks for real permissions and syncs with your calendar app.

Leantime moved from 3.10 to 3.14 between October and 10 November. v3.14.0 replaces role-rank checks with specific permission checks across projects, timesheets, users, API keys, to-dos, milestones and sprints, and opens the calendar to plugins; a new CalDAV plugin syncs both ways with Nextcloud, Radicale and Apple Calendar. Earlier releases added mobile push, per-project modules, global search and self-updating plugins.

What is Sugar Calendar?

Sugar Calendar stops being a second copy of your schedule, with two-way Google sync.

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.

Leantime vs Sugar Calendar: editorial side-by-side

L5.0

Leantime swaps role ranks for real permissions and syncs with your calendar app.

◆ Current state

Leantime moved from 3.10 to 3.14 between October and 10 November. v3.14.0 replaces role-rank checks with specific permission checks across projects, timesheets, users, API keys, to-dos, milestones and sprints, and opens the calendar to plugins; a new CalDAV plugin syncs both ways with Nextcloud, Radicale and Apple Calendar. Earlier releases added mobile push, per-project modules, global search and self-updating plugins.

◆ Where it's heading

The release cadence is roughly one feature version every two weeks, split between finer access control and a plugin marketplace that carries more functionality. Core changes increasingly exist to give plugins stable hooks, as the calendar rework shows.

◆ Prediction

Expect more marketplace plugins built on the new calendar and permission hooks, and further permission work extending to the remaining modules.

S5.0

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.
