[Koha] Koha 18.05.00 released

[Jonathan Druart]

Hello everybody,

It is with great pleasure that the Koha community announces the release of
Koha 18.05, a major release of the Koha open source integrated library
system.

Read the full release notes here:
https://koha-community.org/koha-18-05-released/

If you do not usually read the release notes, you should at least read the
new "Important notes" section at the top.

The Debian packages for this new version will be available soon. Stay tuned!

They are supposed to work out-of-the-box on:
* Debian Jessie (8)
* Debian Stretch (9)
* Ubuntu Xenial (16.04 LTS)
And should work without too much trouble under Ubuntu Bionic (18.04 LTC),
check the install wiki page for more information.

Cheers,
Jonathan
