[Fridolin SOMERS]

The Koha community is proud to announce the release of Koha 17.11.15.

This is a maintenance release.

The full release notes are available at 
https://koha-community.org/koha-17-11-15-release/

Debian packages will be upgraded in a few days.

I may end this maintaining with 19.05 release in may, so last version 
should be 17.11.18.
