 - Clear the release notes and move them to the wiki (see "Write the release notes" below).
 - Translations on Transifex:
     - Pull translations from Transifex into the master branch.
-    - Create [a new resource](https://www.transifex.com/bitcoin/bitcoin/content/) named after the major version with the slug `qt-translation-<RRR>x`, where `RRR` is the major branch number padded with zeros. Use `src/qt/locale/bitcoin_en.xlf` to create it.

     - In the project workflow settings, ensure that [Translation Memory Fill-up](https://help.transifex.com/en/articles/6224817-setting-up-translation-memory-fill-up) is enabled and that [Translation Memory Context Matching](https://help.transifex.com/en/articles/6224753-translation-memory-with-context) is disabled.
     - Update the Transifex slug in [`.tx/config`](/.tx/config) to the slug of the resource created in the first step. This identifies which resource the translations will be synchronized from.
-    - Make an announcement that translators can start translating for the new version. You can use one of the [previous announcements](https://www.transifex.com/bitcoin/communication/) as a template.

     - Change the auto-update URL for the resource to `master`, e.g. `https://raw.githubusercontent.com/bitcoin/bitcoin/master/src/qt/locale/bitcoin_en.xlf`. (Do this only after the previous steps, to prevent an auto-update from interfering.)
