[Koha] Koha 17.11.13 release

[Fridolin SOMERS]

The Koha community is proud to announce the release of Koha 17.11.13.

This is a maintenance release.

The full release notes are available at 
https://koha-community.org/koha-17-11-13-release/

Debian packages will be upgraded in a few days.

Pay attention to Bug 21955 integration : Cache::Memory should not be 
used as L2 cache.
This means Memcached is more than recommanded on production servers.

Have a nice end of the year and merry christmas ;)

Hohoho,
