Tk::804delta - what is new for perl/Tk 804 DESCRIPTION
This document describes differences between the Tk800 series and the Tk804 series. Incompatible Changes In Tk804.028, there are some additional incompatible changes: Return values of some Tk::Wm methods (e.g. aspect, wmGrid, iconposition, resizable ...) were changed from returning tclish lists (e.g. "1 2 3 4") to perlish lists (1,2,3,4). Tk::Wm::wmTracing needs argument for setting on/off, without argument just return the current value. All Tk804 releases have the following incompatible changes: Tk804 will only work with perl 5.8.0 and above. For older perl versions look for Tk800.025. curselection of Tk::Listbox now returns an array reference in scalar context. This means you have to write my(@selected) = $listbox->curselection or my(@selected) = @{ $listbox->curselection } now. The fontActual method now returns the pixel value instead of the point value for -size. Pixel values are expressed as negative numbers. Some enhancements from the "dash" patches are lost for now (i.e. -tile, -troughtile ...). The -state option is not available anymore for Tk::Text tags. Use -elide instead. Enhancements Tk804 is Unicode-aware. It is possible to build Tk with Xft support on X11. This is strongly recommened if you are planning to make use of Unicode rendering capabilities of Tk. It also gives anti-aliased fonts for regular text (if you have TrueType or Type1 fonts and they are in your fontconfig config file). The new method chooseDirectory is available as a standard directory selector. Tk::PNG and Tk::JPEG are bundled now with the perl/Tk distribution, providing support for the image formats png and jpeg. Improvements to Tk::Listbox: new option -activestyle, new methods itemconfigure and itemcget, new virtual event <<ListboxSelect>>. More tests. New Widgets Tk::Labelframe An alternative to Tk::LabFrame. Tk::Panedwindow An alternative to Tk::Adjuster. Tk::Spinbox An alternative to the CPAN module Tk::NumEntry. Selected Bug Fixes Changed Internals Platform Specific Problems Future Directions Reporting Bugs If you find what you think is a bug, you might check the articles recently posted to the comp.lang.perl.tk newsgroup. If you believe you have an unreported bug, please send a mail to <ptk@lists.stanford.edu> and/or <nick@ing-simmons.net>. Be sure to trim your bug down to a tiny but sufficient test case. SEE ALSO

perl582delta - what is new for perl v5.8.2 DESCRIPTION
This document describes differences between the 5.8.1 release and the 5.8.2 release. If you are upgrading from an earlier release such as 5.6.1, first read the perl58delta, which describes differences between 5.6.0 and 5.8.0, and the perl581delta, which describes differences between 5.8.0 and 5.8.1. Incompatible Changes For threaded builds for modules calling certain re-entrant system calls, binary compatibility was accidentally lost between 5.8.0 and 5.8.1. Binary compatibility with 5.8.0 has been restored in 5.8.2, which necessitates breaking compatibility with 5.8.1. We see this as the lesser of two evils. 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. Core Enhancements 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. 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. Threading Several memory leaks associated with variables shared between threads have been fixed. Modules and Pragmata Updated Modules And Pragmata The following modules and pragmata have been updated since Perl 5.8.1: Devel::PPPort Digest::MD5 I18N::LangTags libnet MIME::Base64 Pod::Perldoc strict Documentation improved Tie::Hash Documentation improved Time::HiRes Unicode::Collate Unicode::Normalize UNIVERSAL Documentation improved Selected Bug Fixes Some syntax errors involving unrecognized filetest operators are now handled correctly by the parser. 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. Platform Specific Problems Dynamic linker flags have been tweaked for Solaris and OS X, which should solve problems seen while building some XS modules. Bugs in OS/2 sockets and tmpfile have been fixed. In OS X "setreuid" and friends are troublesome - perl will now work around their problems as best possible. 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 o 5.8.3 23:59:59 GMT, Wednesday December 31st 2003 o 5.8.4 23:59:59 GMT, Wednesday March 31st 2004 o 5.8.5 23:59:59 GMT, Wednesday June 30th 2004 with the release following soon after, when testing is complete. See "Future Directions" in perl581delta for more soothsaying. 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. If you believe you have an unreported bug, please run the perlbug 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 "perl -V", 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/ SEE ALSO
