When a UTF-8 constant string was used as the hash key in an insert operation, such as $hash{'über maus'} = 1;, and the string could be converted into a single byte representation, the flag noting the original encoding (HVhek_WASUTF8) was not always retained.
When this occurred, the relevant scalars returned by keys %hash would not be in the original, expected UTF-8 encoding.
The original encoding is now captured and propagated. [GH #24266]
When a constant IV or NV was used as a hash key, such as in my %hash = ( 42 = 0 );>, and was preemptively stringified into a hash key, the fact that the numerical value came first was lost. This unintentionally modified deparse output for such keys.
The numerical values are now carried across, and flags on the key variable reflect the original data type.
Note: This now preserves the form of constant keys supplied to tied hashes in list assignments. [GH #24302]
"defer_error" in perlapi, formerly known as qerror, and "op_clear" in perlapi are now part of the API.
Perl 5.43.2 hid Perl non-API function declarations unless you defined PERL_EXT or PERL_CORE, so these non-API functions no longer had visible declarations.
A small number of CPAN modules used these APIs and a stricter GCC 15 started enforcing C99 disallowing implicit function declarations, producing build failures.
Added qerror() as a deprecated public alias for defer_error() to allow existing users of that name to build successfully.
Perl 5.43.10 represents approximately 4 weeks of development since Perl 5.43.9 and contains approximately 21,000 lines of changes across 240 files from 20 authors.
Excluding auto-generated files, documentation and release tools, there were approximately 17,000 lines of changes to 120 .pm, .t, .c and .h files.

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.

If you find what you think is a bug, you might check the perl bug database at https://github.com/Perl/perl5/issues. There may also be information at https://www.perl.org/, the Perl Home Page.
If you believe you have an unreported bug, please open an issue at https://github.com/Perl/perl5/issues. Be sure to trim your bug down to a tiny but sufficient test case.
If the bug you are reporting has security implications which make it inappropriate to send to a public issue tracker, then see "SECURITY VULNERABILITY CONTACT INFORMATION" in perlsec for details of how to report the issue.
