Mp3tag v3.00 released

Mp3tag v3.00 released

We’ve reached v3.00 :raised_hands:

All of you who are in there since v2.50 (released in 2012) or even v2.00 (released in 2002) know how many changes, improvements, and new features went into Mp3tag throughout the years. And yes, it means that we did this now 100 times since v2.00 (not counting the ~5 beta versions per final release).

As you probably can tell, I’m proud today. I also feel tremendous gratitude towards everyone who has supported me on that ongoing journey.
Thanks a lot for being part of this!

I’ve also wanted to take the opportunity to detail some of the new features and changes for you.

Action "Adjust cover" to resize cover art

Many hardware players have certain limitations on the size of cover art and then it's sometimes just nice to scale down this 10000x10000 cover to a reasonable size. You can also use this action type to convert from JPEG to PNG or vice versa. It's quite handy and I hope it improves your workflow.

MusicBrainz tag sources with multiple search criteria

The MusicBrainz tag source now also offers two distinct search fields for album and artist and adds support for MUSICBRAINZ_RELEASEGROUPID along the way.

Accessibility related improvements

I've reworked most of the menu-drawing code in high-contrast modes so that it is now more in line with the native menus that the various supported versions of Windows are providing. Also, some buttons and menus were not accessible to screen readers ‐ if you're noticing something like that, please let me know.

:rocket: Download the new version (it's v3.00! :tada:)

:orange_heart: Support my work as an Indie Developer

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