"This update for rmt-server fixes the following issues :

Update to version 2.6.5: Solved potential bug of SCC repository URLs
changing over time. RMT now self heals by removing the previous
invalid repository and creating the correct one.

Add web server settings to /etc/rmt.conf: Now it's possible to
configure the minimum and maximum threads count as well the number of
web server workers to be booted through /etc/rmt.conf.

Instead of using an MD5 of URLs for custom repository friendly_ids,
RMT now builds an ID from the name.

Fix RMT file caching based on timestamps: Previously, RMT sent GET
requests with the header 'If-Modified-Since' to a repository server
and if the response had a 304 (Not Modified), it would copy a file
from the local cache instead of downloading. However, if the local
file timestamp accidentally changed to a date newer than the one on
the repository server, RMT would have an outdated file, which caused
some errors. Now, RMT makes HEAD requests to the repositories servers
and inspect the 'Last-Modified' header to decide whether to download a
file or copy it from cache, by comparing the equalness of timestamps.

Fixed an issue where relative paths supplied to `rmt-cli import repos`
caused the command to fail.

Friendlier IDs for custom repositories: In an effort to simplify the
handling of SCC and custom repositories, RMT now has friendly IDs. For
SCC repositories, it's the same SCC ID as before. For custom
repositories, it can either be user provided or RMT generated (MD5 of
the provided URL). Benefits :

  - `rmt-cli mirror repositories` now works for custom
    repositories.

  - Custom repository IDs can be the same across RMT
    instances.

  - No more confusing 'SCC ID' vs 'ID' in `rmt-cli` output.
    Deprecation Warnings :

  - RMT now uses a different ID for custom repositories than
    before. RMT still supports that old ID, but it's
    recommended to start using the new ID to ensure future
    compatibility.

Updated rails and puma dependencies for security fixes.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
