Original changelog

1.0.2

• Fixed: in Firefox Nightly 57, the list of available locales was not being built neither in the toolbar button nor in the languages window of the add-on, making impossible to switch between languages.

1.0.1

• Added a new localization: Catalan (ca). Thanks to Xavi Ivars from Softcatalà, via babelzilla.org, for providing it.
• Other minor fixes.

1.0.0

• Changed: the minimum supported application versions are now Firefox 52, Thunderbird 52 and SeaMonkey 2.46.
• Fixed: the default destination for the "Get more language packs…" command has been updated for some cases:
  • Users of beta builds of Firefox and Thunderbird will find the language packs released for their exact beta build number, instead of the first packs released for that application version.
  • The new Firefox Developer Edition, built now from Beta Firefox builds instead, is now supported.

Compatibility

• Firefox 52.0 - 56.*
• Thunderbird 52.0 - 56.*
