Monthly Update: Preview of the New Features in Pre-release Redmine! In-browser Preview for Office Documents and More (March 2026 Commit Highlights)

I introduce the new features that have been committed in the official Redmine repository and will be included in the upcoming release. Let's preview the upcoming features that will make Redmine even more useful.

This month, I'll highlight 4 issues out of the 17 committed in March 2026.

• In-browser Preview for Office and LibreOffice Documents
• Support for CSS text-decoration Property
• "Watched items" Added to Email Notification Settings
• CSV Export for Project Member Lists

In-browser Preview for Office and LibreOffice Documents

Microsoft Office files (.docx, .xlsx, .pptx) and LibreOffice files (.odt) attached to issues or other modules can now be previewed directly in the browser without downloading them.

This feature significantly improves productivity by allowing users to quickly check the content of attached documents without leaving the Redmine interface.

• Expected version: Redmine 7.0.0
• Official site issue: Feature #8959: Preview of office and libreoffice documents

Support for CSS text-decoration Property

The CSS text-decoration property can now be used in text formatting for issue descriptions, Wiki pages, and more.

This allows for more flexible styling, such as strikethrough, underlines, or wavy lines, using standard CSS syntax within the supported text formatting.

• Expected version: Redmine 7.0.0
• Official site issue: Feature #42444: Allow text-decoration in text formatting

"Only for things I watch" Added to Email Notification Settings

A new "Only for things I watch" option has been added to the email notification settings in My Account.

Previously, users would receive notifications for issues they were watching based on broader settings. With this new option, you can choose to receive notifications only for the issues you are explicitly watching, even if you are not the author or assignee. This makes it much easier to filter and manage the volume of notification emails.

• Expected version: Redmine 7.0.0
• Official site issue: Feature #37978: Add "Watched items" to email notification options

CSV Export for Project Member Lists

The project member list (Project Settings → Members) can now be exported in CSV format.

This is particularly useful for auditing permissions or managing a large number of members. It allows administrators to easily extract the member list for reporting or further analysis in spreadsheet software.

• Expected version: Redmine 7.0.0
• Official site issue: Feature #37480: CSV export for project members list
