What's new
Subtasks
Break a big issue into smaller ones. The parent shows 3/5 on the board and its subtasks
sit under it instead of taking columns of their own. Archive the parent and they go with
it, restore it and they come back.
Links between issues
Mark what blocks what, what is related and what is a duplicate. Both issues carry the link, so the blocker is visible from either end, on the issue page and on the board.
Watch an issue
You now choose what you hear about. Unsubscribe from a noisy issue and it stays quiet, even after you comment on it again. Issues you create, get assigned, comment on or are mentioned in subscribe you on their own, and Preferences turns that off.
Draw on screenshots
Circle the bug and save. The image updates everywhere it is already used, so you need neither another tool nor a second upload. Attachments are preview cards you can open and look at.
A faster new issue dialog
Paste a big screenshot and the Create issue button stays where it is. Custom fields sit in tabs and attachments in a thumbnail strip, so the whole dialog fits on one screen.
The activity log, by status
The log groups the issue's history into the stretches it spent in each status: how long it sat there and what was said while it did. Preferences picks the view it opens with.
Polish
Better contrast in dark theme, long titles shown in full, dialogs that scroll again, a navigation rail in preferences, and permissions that match what you can actually do.
