Multilingual App Toolkit support ended on October 15, 2025
The Multilingual App Toolkit has been deprecated. This toolkit reached end-of-support on October 15, 2025, and is no longer supported.
If you are an existing user of the Multilingual App Toolkit, you can continue to use it without any loss of functionality after this date. However, no further updates are planned, and new installations will not be possible after October 15, 2025.
As this toolkit uses the industry standard XLIFF format, consider using a similar Computer-Aided Translation (CAT) tool that supports this format.
