Currently running Koha 16.11.11.000 on Ubuntu 14.04.5 LTS, which was
previously installed by package method (previous versions).
And about Koha page shows, Perl version as: 5.018002
and It is mentioned that update from 16.11.11 to 16.11.14 requires Perl
5.10 at https://koha-community.org/koha-16-11-14-release/
Does update in Koha automatically brings Perl 5.10 or should it be manually
