RUBY server update 2.3.12.0 and licencing

RUBY SERVER UPDATE 2.3.12.0

A reminder to all technicians that the process of updating from RUBY 2.3.10 and 2.3.11
to 2.3.12 will cause the licence to expire, and it will be necessary to reregister the
software. This is because of a bug that was present in 2.3.10 and 2.3.11 causing the
licence to expire during the updating process. Updating to 2.3.12.0 from version 2.3.9
or earlier will not cause any problems.
