 If this pull request will result in a new version-numbered release (see the "Version numbers" section above), then also do the following:
 
-- [ ] Add a new level 2 header to `CHANGELOG.md` just above the header of most recent previous version-numbered release. The header should follow the following format, where `version_number` is your new version number from the "Version numbers" section above and `date` is today's date.
+- [ ] Add a new level 2 header to `CHANGELOG.md` just above the header of most recent previous version-numbered release. The header should follow the following format, where `version_number` is your new version number from the "Version numbers" section above:
+
       ```
-      [${version_number} - ${date}] [${version_number}]
+      [${version_number}]
       ```
+
 - [ ] Move all unreleased changes under the `[Unreleased]` header on line 8 of `CHANGELOG.md` to instead be under your new header from the previous step.
 - [ ] Near the bottom of `CHANGELOG.md`, underneath the line which begins with `[Unreleased]:` add a line which follows the following format, where `version_number` is the same as the previous step and `previous_version_number` is the most recent version number prior to your new one:
+
       ```
       [${version_number}]: https://github.com/wesnel/elsewhere/compare/v${previous_version_number}...v${version_number}
       ```

 - [ ] Near the bottom of `CHANGELOG.md`, edit the line which begins with `[Unreleased]:` to contain your new `version_number` from the previous step:
+
       ```
       [Unreleased]: https://github.com/wesnel/elsewhere/compare/v${version_number}...HEAD
       ```
