Monthly Update: Preview of New Features in Pre-release Redmine! Adobe Illustrator File Previews and More (August 2026 Commit Highlights)
I would like to introduce the new features that were committed to the official Redmine repository last month. Let's check out the new features that make Redmine even more useful.
This month, I'll highlight 2 issues out of the 41 committed in August 2026.
What is Redmine?
Redmine is open source project management software. It can be freely installed on self-hosted servers or used via cloud services. For more information about Redmine, visit the official site.
Support for Adobe Illustrator File Previews
Adobe Illustrator files (.ai) attached to Redmine can now be previewed directly in the browser, just like PDF files. Previously, thumbnails could be displayed, but previews were not supported.

Preview Adobe Illustrator files directly in the browser
This feature supports Illustrator files saved with PDF compatibility enabled, which is the default in Adobe Illustrator. Files saved in the older PostScript format cannot be previewed.

A dedicated icon has also been added for Illustrator files
- Implemented version: Redmine 7.1.0
- Official site issue: Feature #44362: Preview PDF compatible Adobe Illustrator files
Latest Note Author Added to the Assignee Dropdown
When editing an issue, the "Author / Previous assignee" group in the assignee dropdown now also includes the user who posted the latest note. This makes it easier to assign the issue back to someone you have been discussing it with, without searching through the full list of members.
The "Author / Previous assignee" group introduced in Redmine 6.0 has also been renamed to "Author / Recent participants" to reflect this change.

The issue author, previous assignee, and latest note author are shown together
- Implemented version: Redmine 7.1.0
- Official site issue: Feature #44021: Include the latest note author in the assignee dropdown's "Author / Previous assignee" group and rename it to "Author / Recent participants"
