[2347](https://github.com/pulp/pulp_rpm/issues/2347)
- Added a per-package changelog entry limit with a default value of 10, which is controlled by a setting named KEEP_CHANGELOG_LIMIT. This only impacts the output of [dnf changelog $package]{.title-ref} - it is always possible to get the full list of changelogs using [rpm -qa --changelog $package]{.title-ref} if the package is installed on the system. This limit can yield very substantial savings time and resources for some repositories.

Bugfixes

- Added a sync_policy parameter to the /sync/ endpoint which will replace the mirror parameter and provides options for how the sync should be carried out. The mirror parameter is deprecated but will retain its current function.

- Fixed sync of repositories using 'sha' as an alias for the sha1 checksum-type.

[9625](https://pulp.plan.io/issues/9625)
- Ensured that RPM plugin uses only a worker working directory and not /tmp which could have caused the out-of-disc-space issue since it's not expected that Pulp uses /tmp.
