We have attempted to update the documentation to reflect the changes listed in this document. If you find any we have missed, open an issue at https://github.com/Perl/perl5/issues.
Additionally, the following selected changes have been made:
Document that caller() does not see try{} blocks
document how to create a remote-tracking branch for every PR
document how to get a PR as a local branch
Fix description of what Perl does with unencoded strings
Tests were added and changed to reflect the other additions and changes in this release. Furthermore, these significant changes were made:
Split Config-dependent tests in t/opbasic/arith.t to t/op/arith2.t
A set of cop_hints_exists_{pv,pvn,pvs,sv} functions was added, to support checking for the existence of keys in the hints hash of a specific cop without needing to create a mortal copy of said value.
An aid has been added for using the DEBUG macros when debugging XS or C code. The comments in perl.h describe DEBUG_PRE_STMTS and DEBUG_POST_STMTS. which you can #define to do things like save and restore errno, in case the DEBUG calls are interfering with that, or to display timestamps, or which thread it's coming from, or the location of the call, or whatever. You can make a quick hack to help you track something down without having to edit individual DEBUG calls.
Make REFCOUNTED_HE_EXISTS available outside of core
Fix a memory leak in regcomp.c (GH #18604)

The list above is almost certainly incomplete as it is automatically generated from version control history. In particular, it does not include the names of the (very much appreciated) contributors who reported issues to the Perl bug tracker.
Many of the changes included in this version originated in the CPAN modules included in Perl's core. We're grateful to the entire CPAN community for helping Perl to flourish.
