perldelta - what is new for perl v5.35.3


This document describes differences between the 5.35.2 release and the 5.35.3 release.

If you are upgrading from an earlier release such as 5.35.1, first read perl5352delta, which describes differences between 5.35.1 and 5.35.2.


With this release, the experimental switch feature, present in every feature bundle since they were introduced in v5.10, has been removed from the v5.36 bundle. If you want to live dangerously and use it, you'll have to enable it explicitly.
