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.

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.

use v5.35 (or higher) declaration.

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.
:win32 IO pseudolayer is removed (this happened in 5.35.2).
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)
Macros have been added to perl.h to facilitate version comparisons:
Inline functions have been added to embed.h to determine the position of the least significant 1 bit in a word:
Use of the
mktables debugging facility would cause perl to croak since v5.31.10; this problem has now been fixed.
makedepend logic is now compatible with BSD make (fixes GH #19046).
perl5300delta mistakenly identified a CVE whose correct identification is CVE-2015-1592.
