## Backward Incompatibilities {#sec-nixpkgs-release-26.11-incompatibilities}

<!-- To avoid merge conflicts, consider adding your item at an arbitrary place in the list instead. -->

- `hurl` has been updated to `8.x.x` which has some breaking changes. See [upstream changelog](https://github.com/Orange-OpenSource/hurl/releases/tag/8.0.0) for details.
- `python3Packages.django-health-check` has been updated to major version 4. See its [migration guide](https://codingjoe.dev/django-health-check/migrate-to-v4/) and [changelog](https://github.com/codingjoe/django-health-check/releases/tag/4.0.0) for breaking changes.

- `libgdata` has been removed, as it was archived upstream and relied on the insecure libsoup 2.4.

- `uhttpmock` providing 0.0 ABI was removed. `uhttpmock_1_0` providing 1.0 ABI was renamed to `uhttpmock` and `uhttpmock_1_0` was kept as an alias.

- `requireFile` now sets `meta.license = lib.licenses.unfree` by default. Users of `requireFile`-based derivations that preserve this default will need to explicitly allow their evaluation as described in [](#sec-allow-unfree).

- `librest` providing 0.7 ABI was removed. `librest_1_0` providing 1.0 ABI was renamed to `librest` and `librest_1_0` was kept as an alias.

## Other Notable Changes {#sec-nixpkgs-release-26.11-notable-changes}

<!-- To avoid merge conflicts, consider adding your item at an arbitrary place in the list instead. -->

- Package-URL (PURL, https://github.com/package-url/purl-spec) metadata identifier has been added for `fetchgit`, `fetchpypi` and `fetchFromGithub` fetchers.
  `mkDerivation` has been adjusted to reuse this information.
  Package-URLs allow reliably identifying and locating software packages.
  Maintainers of derivations using the adapted fetchers should rely on the `drv.src.meta.identifiers.v1.purl` default identifier and can enhance their `drv.meta.identifiers.v1.purls` list once they would like to have additional identifiers.
  Maintainers using `fetchurl` for `drv.src` are urged to adapt their `drv.meta.identifiers.purlParts` for proper identification.
