Make sure to check out the explanation about “Fire starts here”, and the possible l10n alternative “It starts here”. Strings will be exposed in a few hours.
The onboarding has been updated for Windows 10, with a new panel using strings that were translated for a different panel. You might want to double check that.
A reminder that the deadline to update your localization is May 23 (next Sunday).
Please take a look when you have a chance, as there are important things to know before jumping into translations. The new strings will be available before the end of the day, and probably get one more update over the week-end.
