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.
Added the Configure option -Dusedefaultstrict to enable strict by default in perl programs when not invoked with -e or -E. This is a diagnostic tool for development.
We now trap SIGBUS when Configure checks for va_copy.
va_copy
On several systems the attempt to determine if we need va_copy or similar results in a SIGBUS instead of the expected SIGSEGV, which previously caused a core dump.
[GH #18148]
Tests were added and changed to reflect the other additions and changes in this release.
The same manifest is now used for Visual C++ and gcc builds.
Previously, MSVC builds were using the /manifestdependency flag instead of embedding perlexe.manifest, which caused issues such as GetVersionEx() returning the wrong version number on Windows 10.
GetVersionEx()
The re module has a new function optimization, which can return a hashref of optimization data discovered about a compiled regexp.
optimization
Fixed a bug in which some regexps with recursive subpatterns matched incorrectly.
[GH #18096]

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.
