Redmine

Setting the target version to 7.1.0.

I have updated the patch. The changes from the original patch are as follows.

• The MIME type is now separated from the date and time by a comma instead of being enclosed in parentheses, for example "Redmine Admin, 08/31/2026 01:07 PM, application/pdf". A value in parentheses placed right after the time could be read as a supplement to the time, especially by users who are not familiar with MIME types.
• The description of the attachment is now displayed on its own line instead of being joined to the author and the date with " - ". Previously, the author and the date started at a different position depending on the presence and the length of the description. This matters more now that the MIME type is added to the same line.
• For Microsoft Office (Office Open XML) and OpenDocument files, the name of the type such as "Microsoft Word Document" or "OpenDocument Spreadsheet" is now displayed instead of the MIME type. This is because their MIME types are among the longest and the hardest to understand, despite the fact that these files are the most likely to be attached. For example, it is difficult to tell that "application/vnd.openxmlformats-officedocument.wordprocessingml.document" is a Word document. Users can still see the original MIME type in a tooltip by hovering the mouse pointer over the name.

All other MIME types are still displayed as they are. Most MIME types, such as application/pdf, image/jpeg and application/zip, are short and tell what the file is at a glance, so there is no need to replace them with names.

The MIME types that are displayed as names are as follows.

Committed the patches in r25128, r25129 and r25130.

The attachment preview page now displays the MIME type of the attachment on the line that shows the author and the creation date.

For Microsoft Office and OpenDocument (LibreOffice) files, a friendly name such as "Microsoft Word Document" is displayed instead of the MIME type, because their MIME types such as "application/vnd.openxmlformats-officedocument.wordprocessingml.document" are long and do not convey the kind of file to most users, although these files are attached frequently. The MIME type of such a file is available as a tooltip on the friendly name. The MIME types for which a friendly name is displayed, and their friendly names, are defined in the constant Redmine::MimeType::FRIENDLY_NAMES in source:trunk/lib/redmine/mime_type.rb@25130#L60.
