What are freezes, translation deadlines etc?
A string freeze is a date when translatable strings and user- interfaces are frozen. It’s a point in time as of which no new strings or modification of existing strings marked for translation are allowed for this project. The purpose of the string freeze is to help ensure high quality translations in the final release, by giving translators adequate time to finish their work and to guarantee that this work will end up in the final release. The translation deadline is a point in time as of which all translations which have been contributed/submitted are guaranteed to get in the release. Translators know they have up to this date to work, and the maintainer needs to package or re-package the project’s final release after this date.
