(To view the differences between the 5.6.0 release and the 5.7.0 release, see L<perl570delta>. To view the differences between the 5.7.0 release and the 5.7.1 release, see L<perl571delta>. To view the differences between the 5.7.1 release and the 5.7.2 release, see L<perl572delta>.) =head1 Changes This is just a selected list of some of the more notable changes. The numbers refer to the Perl repository change numbers; see L<Changes58> (or L<Changes> in Perl 5.8.1). In addition to these changes, lots of work took place in integrating threads, PerlIO, and Unicode; general code cleanup; and last but not least porting to non-UNIX lands such as Win32, VMS, Cygwin, DJGPP, VOS, MacOS Classic, and EBCDIC. =over 4 =item 11362 add LC_MESSAGES to POSIX :locale_h export tag =item 11371 add DEL to [:cntrl:] =item 11375 make h2ph understand constants like 1234L and 5678LL =item 11405 Win32: fix bugs in handling of the virtualized environment =item 11410 fix a bug in the security taint checking of open() =item 11423 make perl fork() safe even on platforms that don't have pthread_atfork() =item 11459 make switching optimization and debugging levels during Perl builds easier via the OPTIMIZE environment variable =item 11475 make split()'s unused captures to be undef, not '' =item 11485 Search::Dict: allow transforming lines before comparing =item 11490 allow installing extra modules or bundles when building Perl =item 11516 add -Wall in cflags when compiling with gcc to weed out dubious C practices =item 11541 pluggable optimizer =item 11549 WinCE: integrate the port =item 11589 Win32: 4-arg select was broken =item 11594 introduce the perlivp utility for verifying the Perl installation (IVP = Installation Verification Procedure) =item 11623 rename lib/unicode to lib/unicore to avoid case-insensitivity problems with lib/Unicode =item 111631 remove Time::Piece =item 11643 document that use utf8 is not the right way most of the time =item 11656 allow building perl with -DUSE_UTF8_SCRIPTS which makes UTF-8 the default script encoding (not the default since that would break all scripts having legacy eight-bit data in them) =item 11725 division preserving 64-bit integers =item 11743 document the coderef-in-@INC feature =item 11794 modulo (%) preserving 64-bit integers =item 11825 update to Unicode 3.1.1 =item 11865 add the \[$@%&*] prototype support =item 11874 oct() and hex() in glorious 64 bit =item 11877 Class::Struct: allow recursive classes =item 11993 fix unpack U to be the reverse of pack U =item 12056 VMS: waitpid enhancements =item 12180 unpack("Z*Z*", pack("Z*Z*", ..)) was broken =item 12243 Devel::Peek: display UTF-8 SVs also as \x{...} =item 12288 Data::Dumper: option to sort hashes =item 12542 add perlpodspec =item 12652 threadsafe DynaLoader, re, Opcode, File::Glob, and B =item 12756 support BeOS better =item 12874 read-only hashes (user-level interface is Hash::Util) =item 13162 add Devel::PPPort =item 13179 add the sort pragma =item 13326 VMS: fix perl -P =item 13358 add perlpacktut =item 13452 SUPER-UX: add hints file =item 13575 Win32: non-blocking waitpid(-1,WNOHANG) =item 13684 introduce the -t option for gentler taint checking =item 14694 add the if pragma =item 14832 implement IV/UV/NV/long double un/packing with j/J/F/D =item 14854 document the new taint behaviour of exec LIST and system LIST =back =head1 Reporting Bugs If you find what you think is a bug, you might check the articles recently posted to the comp.lang.perl.misc newsgroup and the perl bug database at http://bugs.perl.org.
