Mp3tag v3.12 released

Mp3tag v3.12 released

Welcome to 2022! It’s my wish that the year has started well for you and that it has something new to offer.

I've just released Mp3tag v3.12 and wanted to outline some of the new features and changes:

Microsoft Store version with context menu

The Microsoft Store version now also comes with a Explorer context-menu extension so that there should be no real differences between the Store version and the standalone version anymore.

MusicBrainz Cover Size

Album covers imported from MusicBrainz can be quite large in their original size (up to several MB). I've now added an configuration option at Options → Tag Sources to choose the size from 250px, 500px, 1200px, and Original.

Open in Windows File Explorer

It's now possible to open files in Explorer from within Mp3tag. This was previously only possible via a user-defined tool at Options → Tools and is now officially built-in — including file selection in Explorer.

:rocket: Download the new version

:orange_heart: Support my work as an Indie Developer

As always, thank you for reading, your interest and your support.

Enjoy and take care

FYI: I uninstalled the standalone version (kept my settings) and installed the Windows Store version -- the context menu item did not show up until I restarted Windows Explorer (right-click->restart in Task Manager; log out or reboot would have also worked).

Thanks for getting that in, was the only hold-up for me. :slight_smile:
