Redmine version 6.1.0 is in the starting blocks. In total, almost 70 issues have been implemented — from small optimizations to completely new features. In this blog post we provide an overview and highlight some key features. You can find the complete changelog on Redmine.org.

Our plugins in v4.1.0 do not yet support the new Redmine version 6.1.0. This will only be the case with one of the subsequent plugin versions. We always recommend checking the minimum requirements first and contacting us if you have any questions.

Key Features for Greater Comfort in Daily Work

Redmine 6.1.0 contains many detailed improvements for users:

  • Copy functions for content: Both API keys and content from pre code blocks can now be copied directly to the clipboard (Feature #5953, #29214).
  • Sticky header for Redmine issues: When scrolling in an issue, the subject will remain visible in the future (Feature #42684).
  • Reactions to content: Issues, notes, news, and forum posts can now be given reactions (Feature #42630).
  • Better display on HiDPI displays: Inserted images automatically adjust to the correct size (Feature #38504).

Note: High Dots Per Inch (HiDPI) is a high pixel density screen, also known as a Retina display.

More Control Over Projects and Tasks

There are also relevant new features for project managers and administrators:

  • Configurable columns for child/related issues: List views can be designed somewhat more flexibly (Feature #42477).
  • New format Progress bar for custom fields: A new custom field format “Progress bar” will be introduced for better visualization of % Done (Feature #42335).
  • Option for time tracking on closed issues: Companies can now determine whether time entries are allowed after closing or not (Feature #13596).
  • Auto-watch configurable: Default settings for automatically watching issues are customizable (Feature #42880).

Note: The dashboard function of the additionals plugin provides its own dashboard, which displays watched content. There you can always find a list of currently watched, open issues.

Technical Improvements

In addition to the visible features, Redmine 6.1.0 also brings many technical innovations under the surface:

  • OAuth2 support for API apps: Redmine can now function as an OAuth2 provider (Feature #24808). More information about OAuth 2.0.
  • Support for Ruby 3.4 (Feature #41976) as well as the Trilogy database adapter (Feature #42675). This makes Redmine fit for modern infrastructures.
  • Stimulus as new JavaScript framework: More modern technology under the hood provides more flexibility for future extensions (Feature #42510). More about the Stimulus framework here.
  • Bullet gem integrated: This automatically detects inefficient database queries, which can improve performance (Feature #42555).

Performance and Usability

Several optimizations improve speed and user-friendliness:

  • Faster loading times in the activity list through optimized queries (Features #42077, #42043).
  • Improved performance for Gantt charts and roadmap views (Features #42663, #42682).
  • Revised display of history tabs for a better, more modern overview (Feature #40744).

Conclusion

Redmine 6.1.0 is a well-thought-out further development and is particularly interesting for users who use Redmine daily. They benefit from comfort functions like sticky headers, copy buttons, and reactions. Administrators appreciate more configuration options and modern interfaces. In addition, the developer community has created a solid foundation for the future with Stimulus and OAuth2.

Anyone who already uses Redmine productively should mark this update on their calendar: It brings not only new features but also numerous optimizations that improve stability and performance.
