Customize columns in the list of related and sub issues

You can now customize the columns and sort order for the "Related issues" and "Subtasks" lists on the issue page. This allows you to personalize the view by adding custom fields, hiding unnecessary columns, and arranging them as you like.

Previously, the list was fixed to display a predefined set of columns, such as Status, Assignee, Start date, Due date, and % Done.

This feature can be configured under Administration → Settings → Issue tracking → "Related and sub issues list defaults". By enabling the "Show table headers" option, the column titles will also be visible in the list.

These settings are common to all projects within your entire Redmine instance.

• Expected version: Redmine 6.1.0
• Official site issue: Feature #42477: Configurable columns for the lists of child and related issues

Button to copy text formatted with <pre> tags to the clipboard

A new button will be added to copy preformatted text (source code displayed as-is within Markdown's ``` or Textile's <pre>) to the clipboard. The button appears when you hover over the preformatted text.

• Expected version: Redmine 6.1.0
• Official site issue: Feature #29214: Button to copy pre code block content to the clipboard

Role deletion error message now displays a list of projects where the role is in use

On the 'Roles and permissions' page (under 'Administration'), when you click 'Delete' for a role, the subsequent message will now list any projects currently using that role. Each project name in this list is a link that directs you to the 'Members' tab of the respective project's settings page.

In earlier versions, a warning would appear if a role was in use, but you needed to manually find out which projects were affected. Starting with the upcoming version, you can simply click a project name in the message to go straight to the 'Members' tab of its settings, allowing for immediate review of how the role is utilized in that project.

• Expected version: Redmine 6.1.0
• Official site issue: Feature #42441: Improve error message on role deletion by listing projects using the role
