This release also includes two noteworthy breaking changes. One is a follow-up on the slugify breaking change from last release. We did not update the validation check for config options that need to be valid slugs. This means that some of your config values might be invalid. Keep an eye at the console as we have a new message to tell you which ones are wrong.
This issue also impacts the entity registry, which could contain in some rare cases invalid entity IDs. Expect entity IDs to change if they contained a double underscore (which becomes 1) or if they started/ended in an underscore (which will be removed).
