This blog is updated daily.
A general description is here.
The included version of PCRE has been updated to 8.34.
There is support to use the shipped Olson time-zone database and (64-bit) time-zone conversion code: use ‘configure’ option ‘--with-internal-tzcode’. (It might be necessary to set environment variable ‘TZ’ on OSes where this is not already set.)
The included version of PCRE has been updated to 8.34. This fixes bugs and makes the behaviour closer to Perl 5.18. In particular, the concept of ‘space’ includes ‘VT’ and hence agrees with POSIX's.
