perl5353delta - 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.
switch
All warnings are enabled automatically within the scope of a use v5.35 (or higher) declaration.

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:
now notes that an invocant only needs to be an object or class name for method calls, not for subroutine references.
notes the :win32 IO pseudolayer is removed (this happened in 5.35.2).
:win32
notes the new location for functions moved from Pod::Html to Pod::Html::Util that are no longer intended to be used outside of core.
The makedepend step is now run in parallel by using make
This reduces the time for
time sh ./makedepend MAKE=make cflags
from 5 seconds to 2 seconds with MAKEFLAGS=-j8
Configure now tests whether #include <xlocale.h> is required to use the POSIX 1003 thread-safe locale functions or some related extensions. This prevents problems where a non-public xlocale.h is removed in a library update, or xlocale.h isn't intended for public use. (github #18936)
#include <xlocale.h>
Macros have been added to perl.h to facilitate version comparisons: PERL_GCC_VERSION_GE, PERL_GCC_VERSION_GT, PERL_GCC_VERSION_LE and PERL_GCC_VERSION_LT.
PERL_GCC_VERSION_GE
PERL_GCC_VERSION_GT
PERL_GCC_VERSION_LE
PERL_GCC_VERSION_LT
Inline functions have been added to embed.h to determine the position of the least significant 1 bit in a word: lsbit_pos32 and lsbit_pos64.
lsbit_pos32
lsbit_pos64
Use of the mktables debugging facility would cause perl to croak since v5.31.10; this problem has now been fixed.
mktables
makedepend logic is now compatible with BSD make (fixes GH #19046).
makedepend

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.
