- `postgresql`'s `pythonSupport` argument has been changed. It is now enabled by default, but to use PL/Python the extension needs to be added explicitly with `postgresql.withPackages`. If you were using `postgresql.override { pythonSupport = true; }` before, change it to `postgresql.withPackages (ps: [ ps.plpython3 ])`. The same applies to `perlSupport`/`plperl` and `tclSupport`/`pltcl` respectively.

- Rust packages will need to regenerate their `cargoHash`.
  Cargo 1.84.0 changed the format of `cargo vendor` output, which invalidated all existing `rustPlatform.fetchCargoTarball` hashes.
  To preserve Nix’s invariants, it has been replaced with `rustPlatform.fetchCargoVendor`, an independent implementation prioritizing format stability.
  `rustPlatform.buildRustPackage` now uses `rustPlatform.fetchCargoVendor` by default; a hash mismatch error is expected in third‐party Rust packages when updating to Nixpkgs 25.05.
  Packages wishing to maintain compatibility with Nixpkgs 24.11 must set `useFetchCargoVendor` to `true` explicitly.
  `rustPlatform.importCargoLock` may also be appropriate in some circumstances.

- `cassandra_3_0` and `cassandra_3_11` have been removed as they have reached end-of-life. Please update to `cassandra_4`. See the [changelog](https://github.com/apache/cassandra/blob/cassandra-4.0.17/NEWS.txt) for more information about the upgrade process.

- `mariadb_105` has been removed as it has reached end-of-life in 2025-06. Please update to `mariadb_106`.

- NetBox was updated to `>= 4.2.0`. Have a look at the breaking changes
  of the [4.1 release](https://github.com/netbox-community/netbox/releases/tag/v4.1.0)
  and the [4.2 release](https://github.com/netbox-community/netbox/releases/tag/v4.2.0),
  make the required changes to your database, if needed, then upgrade by setting `services.netbox.package = pkgs.netbox_4_2;` in your configuration.

- `nodePackages.expo-cli` has been removed, as it was deprecated by upstream. The suggested replacement is the `npx expo` command.

- The `conduwuit` matrix server implementation has officially been discontinued by upstream and the package has thus been marked as vulnerable, as it is a security-sensitive package that has reached EOL.

- NetBox version 4.0.X available as `netbox_4_0` was removed. Please upgrade to `4.2`.

- `golangci-lint` has reached `v2`. Please read the changes and view the migration guide [here](https://golangci-lint.run/product/changelog/#200).

- `i3status-rust`-package no longer enables `notmuch` by default. It can be enabled via `withNotmuch`.

- `ocis-bin` has been renamed to `ocis_5-bin`. Future versions will have the major version suffix.

- All support for 32‐bit Darwin systems has been dropped.

- `substituteAll` and `substituteAllFiles` have been deprecated in favor of `replaceVars` and will be removed in the next release.

- Default ICU version updated from 74 to 76

- The packages `signald`, `signaldctl` and `purple-signald` have been dropped as they are unmaintained upstream and have been incompatible with the official Signal servers for a long while.

- Apache Kafka was updated to `>= 4.0.0`. Please note that this is the first release which operates
  entirely without Apache ZooKeeper support, and all clusters need to be migrated to KRaft mode. See
  the [release announcement](https://kafka.apache.org/blog#apache_kafka_400_release_announcement)
  for more details.

- `ast-grep` remove `sg` command to prevent conflict with `sg` command from shadow-utils. If you need legacy sg command compatibility with old code, you can use `ast-grep.override { enableLegacySg = true; }`

- rename package `wtf` to `wtfutil`.

- `python3Packages.beancount` was updated to 3.1.0. Previous major version remains available as `python3Packages.beancount_2`.

- `wastebin` has been updated to 3.0.0. See the [Changelog](https://github.com/matze/wastebin/blob/master/CHANGELOG.md#300) for breaking changes to the configuration.

- `binwalk` was updated to 3.1.0, which has been rewritten in rust. The python module is no longer available.
