June 6th-11th
News
Following the fixes to [1]Scope::Upper, Dave Mitchell [2]reapplied his
change to eval behavior.
Dave Mitchell has [3]reworked the Perl_sv_vcatpvfn_flags() function,
resulting in 104 commits, 8 bug fixes, 4 buffer sizing and length
calculation overflow/wraps, 4 optimizations (leading to a 15% speed
improvement), and more changes.
Dave Mitchell also [4]suggests changing a sprintf "%c" with a negative
argument to behave the way chr() does, returning a UNICODE_REPLACEMENT
character and a warning.
We are now tracking tickets blocking 5.26.1 in [5]Perl #131533.
[6]Encode is [7]upgraded to version 2.90.
