[tex-live] Biber issue after update

It is true that Biber requires the PAR module.
We can't feasibly provide it (or any other Perl modules) in TL.
So, try running:

cpan install PAR

(Or whatever distro way you have to install CPAN modules.)

On older systems biber may not work at all, and nothing can be done
about that. But I expect 5.26.0 should be ok. --hope this helps, karl.
