+7. Review the changes to the language strings file carefully. You may need to:
+
+    * Edit new strings so they meet [Moodle's guidelines for language strings](https://moodledev.io/general/development/policies/codingstyle#language-strings).
+    * Revert changes to any Moodle-updated language strings that were fixed for spelling, grammar, and consistency in past releases to meet Moodle's guidelines. For example, from the [`en_fix` issues](https://tracker.moodle.org/issues/?jql=summary%20~%20%22en_fix%22%20order%20by%20createdDate%20desc). Review the `git` history of the language strings file to verify.
