Title: mat2 0.12.0
Date: 2020-12-18 20:00

There is a new minor version of MAT2: [0.12.0](https://0xacab.org/jvoisin/mat2/tags/0.12.0),
with no major new features but a couple of enhancements.

# Changelog

- Improve significantly MS Office formats support
- Fix some typos in the Nautilus extension
- Improve reliability of the mp3, pdf and svg parsers
- Improve compatibility with ffmpeg when sandboxing is used
- Improve the dolphin extension usability
- libmat2 now raises a `ValueError` on malformed files while trying to 
  find the right parser, instead of returning `None`

I'm pretty happy about the reliability improvements, since it means less grumpy
users. An other nice surprise is that [someone](https://www.romainvigier.fr/)
spent the time to write an [GTK user interface](https://gitlab.com/rmnvgr/metadata-cleaner)
for mat2, and it looks amazing:

It also helped refining libmat2 to make it easier to be used by external projects.

# Conclusion

A medium release, with nice surprises, and hopefully fewer bugs.
As usual, if you know some python, help is
[more than welcome](https://0xacab.org/jvoisin/mat2/issues?label_name%5B%5D=good+first+issue).
