Nixpkgs 25.05: More Backward Incompatibilities, Updates, and Removals

- `postsrsd` upgraded to `>= 2.0.0`, with some different behaviors and configuration settings. Notably, it now defaults to listening on a socket rather than a port. See [Migrating from version 1.x](https://github.com/roehling/postsrsd/blob/2.0.10/README.rst#migrating-from-version-1x) and [Postfix Setup](https://github.com/roehling/postsrsd?tab=readme-ov-file#postfix-setup) for details. - `renovate` was updated to v39. See the [upstream release notes](https://github.com/renovatebot/renovate/releases/tag/39.0.0) for breaking changes. Like upstream's docker images, renovate now runs on NodeJS 22. - The hand written `perlPackages.SearchXapian` bindings have been dropped in favor of the (mostly compatible) `perlPackages.Xapian`. - `varnish` was updated from 7.5.0 to 7.7.0, see [Varnish 7.6.0 upgrade guide](https://varnish-cache.org/docs/7.6/whats-new/upgrading-7.6.html) and [Varnish 7.7.0 upgrade guide](https://varnish-cache.org/docs/7.7/whats-new/upgrading-7.7.html#whatsnew-upgrading-7-7). - The `config` triple for `aarch64-darwin` has been changed from `aarch64-apple-darwin` to `arm64-apple-darwin` to match the Apple toolchain and LLVM’s expectations. - The `electron` packages will now provide their headers (available via `electron.headers`) in extracted form instead of in a tarball. - The udev rules of the `libjaylink` package require users to be in the `jlink` instead of `plugdev` group now, since the `plugdev` group is very uncommon for NixOS. Alternatively, access is granted to seat sessions. - The `ephemeral` package was removed due to upstream archival in early 2022. - The `gotenberg` package has been updated to 8.16.0, which brings breaking changes to the configuration from version 8.13.0. See the [upstream release notes](https://github.com/gotenberg/gotenberg/releases/tag/v8.13.0) for that release to get all the details. - `zammad` has had its support for MySQL removed, since it was never working correctly and is now deprecated upstream. Check the [migration guide](https://docs.zammad.org/en/latest/appendix/migrate-to-postgresql.html) for how to convert your database to PostgreSQL. - The `vocal` package was removed due to upstream archival. The upstream developer suggests using `gnome-podcasts` or `kasts` instead. - `timescaledb` requires manual upgrade steps. After you run ALTER EXTENSION, you must run [this SQL script](https://github.com/timescale/timescaledb-extras/blob/master/utils/2.15.X-fix_hypertable_foreign_keys.sql). For more details, see the following pull requests [#6797](https://github.com/timescale/timescaledb/pull/6797). PostgreSQL 13 is no longer supported in TimescaleDB v2.16. - `paperless-ngx` has been updated to minor version 2.15 which switched the web server from Gunicorn to Granian. If you set Gunicorn specific envs (usually contain GUNICORN) they must be updated. - [testers.shellcheck](https://nixos.org/manual/nixpkgs/unstable/#tester-shellcheck) now warns when `name` is not provided. The `name` argument will become mandatory in a future release. - `tauon` 7.9.0+ when launched for the first time, migrates its database to a new schema that is not backwards compatible. Older versions will refuse to start at all with that database afterwards. If you need to still use older tauon versions, make sure to back up `~/.local/share/TauonMusicBox`. - `aws-workspaces` has dropped support for PCoiP networking. - [GIMP 3.0](https://www.gimp.org/news/2025/03/16/gimp-3-0-released/) available as `gimp3`. - `grafana-agent` and `services.grafana-agent` have been removed in favor of Grafana Alloy (`grafana-alloy` and `services.alloy`), as they depend on an EOL compiler version and will become EOL during the 25.05 lifecycle. Grafana recommends migrating to `grafana-alloy` (`services.alloy`). See https://grafana.com/docs/alloy/latest/set-up/migrate/ for details. - `slskd` has been updated to v0.22.3, which includes breaking changes to `script` integrations. Please review the [changelog](https://github.com/slskd/slskd/releases/tag/0.22.3)
