Redmine 6.1 Upgrade (Jul 2026)

If you notice any issues with redmine, please contact

New and improved

  • Reactions — you can now give a 👍 (and other reactions) on issues, comments, news, and forum messages.
  • More editor buttons — the wiki/issue toolbar now has emoji, horizontal-rule, link, and image buttons. Typing ## autocompletes an issue reference.
  • Auto-watch — issues you create or comment on are now watched automatically, so you get updates without manually clicking "Watch." You can adjust this under My account → Auto-watch.
  • WebP images are now supported in attachments and thumbnails.
  • Checklists and the distraction-free editor (zenedit) have been updated to their current versions.

Changes to be aware of

  • Notification default — brand-new accounts default to "Only for things I watch or I'm assigned to." Existing accounts keep whatever setting you already had, so nothing changes for you unless you want it to (My account → Email notifications).
  • Stronger password rules — the next time you change your password, it can't match your login, name, or email address.
  • Issue tags have been removed — the issue-tagging plugin was retired (it saw little use). Wiki-page tags still work as before.
