Stable version in 13.X branch

Hi,

I deployed 13.1.1 last month and just some point to check:

• my irule had to be updated (but if you don't use this functionnality, it's OK)

https://support.f5.com/csp/article/K81239824

Otherwise no bug, ASM worked fine and LTM too, on an infra of over 1000 vs so you can go ahead with this version :-).

And as mentionned tiziano check release notes in all case (folow best practice).

regards,
