We see this as the +lesser of two evils. +.PP +This will only affect people who have a threaded perl 5.8.1, and compiled +modules which use these calls, and now attempt to run the compiled modules +with 5.8.2. The fix is to re-compile and re-install the modules using 5.8.2. +.SH "Core Enhancements" +.IX Header "Core Enhancements" +.SS "Hash Randomisation" +.IX Subsection "Hash Randomisation" +The hash randomisation introduced with 5.8.1 has been amended. It +transpired that although the implementation introduced in 5.8.1 was source +compatible with 5.8.0, it was not binary compatible in certain cases. 5.8.2 +contains an improved implementation which is both source and binary +compatible with both 5.8.0 and 5.8.1, and remains robust against the form of +attack which prompted the change for 5.8.1. +.PP +We are grateful to the Debian project for their input in this area. +See "Algorithmic Complexity Attacks" in perlsec for the original +rationale behind this change. +.SS Threading +.IX Subsection "Threading" +Several memory leaks associated with variables shared between threads +have been fixed. +.SH "Modules and Pragmata" +.IX Header "Modules and Pragmata" +.SS "Updated Modules And Pragmata" +.IX Subsection "Updated Modules And Pragmata" +The following modules and pragmata have been updated since Perl 5.8.1: +.IP Devel::PPPort 4 +.IX Item "Devel::PPPort" +.PD 0 +.IP Digest::MD5 4 +.IX Item "Digest::MD5" +.IP I18N::LangTags 4 +.IX Item "I18N::LangTags" +.IP libnet 4 +.IX Item "libnet" +.IP MIME::Base64 4 +.IX Item "MIME::Base64" +.IP Pod::Perldoc 4 +.IX Item "Pod::Perldoc" +.IP strict 4 +.IX Item "strict" +.PD +Documentation improved +.IP Tie::Hash 4 +.IX Item "Tie::Hash" +Documentation improved +.IP Time::HiRes 4 +.IX Item "Time::HiRes" +.PD 0 +.IP Unicode::Collate 4 +.IX Item "Unicode::Collate" +.IP Unicode::Normalize 4 +.IX Item "Unicode::Normalize" +.IP UNIVERSAL 4 +.IX Item "UNIVERSAL" +.PD +Documentation improved +.SH "Selected Bug Fixes" +.IX Header "Selected Bug Fixes" +Some syntax errors involving unrecognized filetest operators are now handled +correctly by the parser. +.SH "Changed Internals" +.IX Header "Changed Internals" +Interpreter initialization is more complete when \-DMULTIPLICITY is off. +This should resolve problems with initializing and destroying the Perl +interpreter more than once in a single process. +.SH "Platform Specific Problems" +.IX Header "Platform Specific Problems" +Dynamic linker flags have been tweaked for Solaris and OS X, which should +solve problems seen while building some XS modules. +.PP +Bugs in OS/2 sockets and tmpfile have been fixed. +.PP +In OS X \f(CW\*(C`setreuid\*(C'\fR and friends are troublesome \- perl will now work +around their problems as best possible. +.SH "Future Directions" +.IX Header "Future Directions" +Starting with 5.8.3 we intend to make more frequent maintenance releases, +with a smaller number of changes in each. The intent is to propagate +bug fixes out to stable releases more rapidly and make upgrading stable +releases less of an upheaval. This should give end users more +flexibility in their choice of upgrade timing, and allow them easier +assessment of the impact of upgrades. The current plan is for code freezes +as follows +.IP \(bu 4 +5.8.3 23:59:59 GMT, Wednesday December 31st 2003 +.IP \(bu 4 +5.8.4 23:59:59 GMT, Wednesday March 31st 2004 +.IP \(bu 4 +5.8.5 23:59:59 GMT, Wednesday June 30th 2004 +.PP +with the release following soon after, when testing is complete. +.PP +See "Future Directions" in perl581delta for more soothsaying. +.SH "Reporting Bugs" +.IX Header "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/. There may also be +information at http://www.perl.com/, the Perl Home Page. +.PP +If you believe you have an unreported bug, please run the \fBperlbug\fR +program included with your release. Be sure to trim your bug down +to a tiny but sufficient test case. Your bug report, along with the +output of \f(CW\*(C`perl \-V\*(C'\fR, will be sent off to perlbug@perl.org to be +analysed by the Perl porting team. You can browse and search +the Perl 5 bugs at http://bugs.perl.org/ +.SH "SEE ALSO" +.IX Header "SEE ALSO" +The \fIChanges\fR file for exhaustive details on what changed. +.PP +The \fIINSTALL\fR file for how to build Perl. +.PP +The \fIREADME\fR file for general stuff. +.PP +The \fIArtistic\fR and \fICopying\fR files for copyright information. |
