Version history / Release notes / Changelog / What's New


# Version 89.0 "And the Melody Still Lingers On (Night in Tunisia)" 2024-12-27

## New features and enhancements

* mkvmerge: AC-3 writer: mkvmerge will now use the codec ID `A_AC3` even for streams with bitstream IDs 9 or 10 instead of the deprecated codec IDs `A_AC3/BSID9` & `A_AC3/BSID10`. Fixes #2387.
* MKVToolNix GUI: multiplexer: the mechanism for setting track languages to specific values upon adding a file has gotten a new option to always set the language, no matter whether or not the source container provided a track language or what it was set to.
* all command-line tools: implemented an escape mechanism for when you want to use the `@` sign as the first character in an argument to an option such as `--title`. To escape it the `@` sign has to be doubled as in `--title @@midnight`. Implements #3768.

## Bug fixes

* mkvmerge, mkvpropedit, MKVToolNix GUI's multiplexer & header editor: the MIME type for TrueType & OpenType fonts will be set properly to either the current MIME types `font/ttf` & `font/otf` or to the legacy MIME types `application/x-truetype-font` & `application/vnd.ms-opentype` depending on whether the "use legacy font MIME types" option is disabled or enabled, even if the MIME database used by Qt returns the wrong one or even other MIME types such as `application/x-font-ttf` & `application/x-font-otf`. This was the case on Windows due to Qt 6.7.3 switching to a different embedded MIME database. Partially fixes #3751.
* MKVToolNix GUI's multiplexer & header editor: ensured that both the legacy & the current font MIME types are always present in the MIME type combo boxes of attachments, no matter what Qt's MIME type database contains. Partially fixes #3751.
* MKVToolNix GUI: the "disable tooltips" option in the preference will now disable the tooltip for the status bar, too.

@ Tagoria: How old are you?

Yoù're provided with this highly functional, top notch software for FREE!

Not that it'd occur to you to leave a "thank you",

you rate it 1/10, even on "value for money".

There's someone working for your benefit, for free,

you might wanna show some gratitude.

And if you got a prob with that app, it works like a charm

for the vast majority of users, so in your case...

.....PEBCAK
