I've updated compare-locales with two important fixes:
- License header fix for ini files, bug 760998
- l10n-merge now works with multiple errors per file, bug 756448
I've also updated the license to MPL2.
Update your local installs with the usual commands, like
pip install -U compare-locales
The l10n dashboard is already running the new code, I'll file a bug to get the production builds updated probably tomorrow.
