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.

perldelta - what is new for perl v5.8.1 DESCRIPTION
This document describes differences between the 5.8.0 release and the 5.8.1 release. Incompatible Changes Core Enhancements Tied Arrays with Negative Array Indices Formerly, the indices passed to "FETCH", "STORE", "EXISTS", and "DELETE" methods in tied array class were always non-negative. If the actual argument was negative, Perl would call FETCHSIZE implicitly and add the result to the index before passing the result to the tied array method. This behavior is now optional. If the tied array class contains a package variable named $NEGATIVE_INDICES which is set to a true value, negative values will be passed to "FETCH", "STORE", "EXISTS", and "DELETE" unchanged. Warnings Perl 5.8.0 forgot to add some deprecation warnings. These warnings have now been added. Pseudo-hashes really are deprecated Pseudo-hashes were deprecated in Perl 5.8.0 and will be removed in Perl 5.10.0, see perl58delta for details. Each attempt to access pseudo-hashes will trigger the warning "Pseudo-hashes are deprecated". If you really want to continue using pseudo-hashes but not to see the deprecation warnings, add: no warnings 'deprecated'; 5.005-style threads really are deprecated 5.005-style threads (activated by "use Thread;") were deprecated in Perl 5.8.0 and will be removed in Perl 5.10.0, see perl58delta for details. Each attempt to create a 5.005-style thread will trigger the warning "5.005 threads are deprecated". If you really want to con- tinue using 5.005 threads but not to see the deprecation warnings, add: no warnings 'deprecated'; Modules and Pragmata Utility Changes New Documentation Performance Enhancements Installation and Configuration Improvements Selected Bug Fixes New or Changed Diagnostics Changed Internals New Tests Known Problems Platform Specific Problems 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.
