Earlier today the auto-update system for WordPress updated some sites from version 5.5.2 to version 5.5.3-alpha. This was due to an error caused by preparations being made for the 5.5.3 release. The 5.5.3-alpha version at this point was functionally identical to 5.5.2 as no development work had been started on 5.5.3, however the following changes may have been made:

The default “Twenty” themes installed as part of the pre-release package.
The “Akismet” plugin installed as part of the pre-release package.

These themes and plugins were not activated and therefore remain non-functional unless you installed them previously. It is safe to delete these features should you prefer not to use them.

The version of your WordPress installation can be reverted to 5.5.2 by visiting the update panel (visiting Dashboard > Updates) and clicking the Re-install WordPress button. This will get a new copy of WordPress, but will not affect your content or uploaded files.

Details can be found in the related ticket at https://core.trac.wordpress.org/ticket/51679
