 There are some notable changes worth mentioning.
 
 ## Restrict experimental features to unstable releases only
-PR [#11920](https://github.com/lampepfl/dotty/pull/11920) restricts usage of experimental features only to nightlies and snapshots. This change ensures that changes deemed experimental will not propagate into the wider ecosystem provided that wider ecosystem depends on stable releases. This is needed so that if an experimental feature is removed from the language, the ecosystem will not be impacted.

 ## New `unsafeNulls` language feature
 PR [#9884](https://github.com/lampepfl/dotty/pull/9884) adds a new language feature which enables explicit nulls checks. From now on, you can use an import `import scala.language.unsafeNulls` to enable the feature, no compiler flags needed. For discussion, see the PR linked above, and for more information on the feature, see the [documentation](https://dotty.epfl.ch/docs/reference/other-new-features/explicit-nulls.html).
