 - `idris2` was updated to v0.7.0. This version introduces breaking changes. Check out the [changelog](https://github.com/idris-lang/Idris2/blob/v0.7.0/CHANGELOG.md#v070) for details.
 
+- `neo4j` has been updated to 5, you may want to read the [release notes for Neo4j 5](https://neo4j.com/release-notes/database/neo4j-5/)
+
+- `services.neo4j.allowUpgrade` was removed and no longer has any effect. Neo4j 5 supports automatic rolling upgrades.

 - `nitter` requires a `guest_accounts.jsonl` to be provided as a path or loaded into the default location at `/var/lib/nitter/guest_accounts.jsonl`. See [Guest Account Branch Deployment](https://github.com/zedeus/nitter/wiki/Guest-Account-Branch-Deployment) for details.
 
 - Invidious has changed its default database username from `kemal` to `invidious`. Setups involving an externally provisioned database (i.e. `services.invidious.database.createLocally == false`) should adjust their configuration accordingly. The old `kemal` user will not be removed automatically even when the database is provisioned automatically.(https://github.com/NixOS/nixpkgs/pull/265857)
