- 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.

- Version 2.6.4
- 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.

- Version 2.6.3
- Instead of using an MD5 of URLs for custom repository friendly_ids,
RMT now builds an ID from the name.

- Version 2.6.2
- 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server, RMT would have an outdated file, which caused some errors.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.

- Version 2.6.1
- Fixed an issue where relative paths supplied to `rmt-cli import repos`
caused the command to fail.
