version 0.9907 ================================== Full version object support, with patch for bug in Perl 5.10.0 core version support. YOU SHOULD INSTALL THIS RELEASE WHEN USING VERSION OBJECTS IN PERL 5.10.0. There was a bug caused by objects serialized by YAML that will cause Perl 5.10.0 to segfault. As long as some module calls 'use version', then the replacement code will take effect and Perl will not crash. Major Changes in 0.9907 - 2014-01-12 ===================================== Lots of optimizations of XS and C code courtesy of Daniel Dragan (bulk88@hotmail.com). Lots of minor tweaks as well. Resolves: https://rt.cpan.org/Ticket/Display.html?id=91892 https://rt.cpan.org/Ticket/Display.html?id=91867 https://rt.cpan.org/Ticket/Display.html?id=91987 https://rt.cpan.org/Ticket/Display.html?id=92051 IMPORTANT CHANGE - 0.9906 is the last release that fully supports Perl releases prior to 5.6.2. It is just too much trouble to continue to fight to maintain full backward compatibility. Major Changes in 0.9906 - 2014-01-04 ===================================== Applied C89 compatibility fix from Karl Williamson to vxs.inc. Added back support for $version::LAX and $version::STRICT to resolve: https://rt.cpan.org/Ticket/Display.html?id=88458 https://rt.cpan.org/Ticket/Display.html?id=91858 https://rt.cpan.org/Ticket/Display.html?id=91868 Major Changes in 0.9905 - 2014-01-04 ===================================== Major rewrite of XS code to permit easier inclusion in core Perl (mostly written by Father Chrysostomos <sprout@cpan.org>). XS code is no longer supported for any Perl < v5.10, although the pure Perl code still works going back to 5.005_04. In addition, the version::vpp class is now completely independent and can be use'd exactly like the base version class. It is still better to use the base class for compatibility purposes. Major Changes in 0.9904 - 2013-08-20 ===================================== Final upstream changes from bleadperl. Resolves RT tickets: https://rt.cpan.org/Ticket/Display.html?id=87513 https://rt.cpan.org/Ticket/Display.html?id=87983 Major Changes in 0.9903 - 2013-08-18 ===================================== Upstream test changes from bleadperl. Include version::vpp even when installing XS version. Subtle locale test changes. Major Changes in 0.9902 - 2013-03-05 ===================================== Upstream test changess from bleadperl. Support env PERL_ONLY=1 as well as --perl-only. version::new with no arguments reads past the end of the stack. Major Changes in 0.9901 - 2012-04-26 ===================================== Fix problem with short floating point alpha versions (e.g. 0.52_0). Major Changes in 0.99 - 2012-04-26 ===================================== Apply missing patch from core Perl to prevent overflow with ludicrous versions. Major Changes in 0.98 - 2012-04-25 ===================================== Apply patch from core Perl to prevent overflow with ludicrous versions. Major Changes in 0.97 - 2012-02-28 ===================================== Minor tweak to locale test to skip if no locales are installed at all. Major Changes in 0.96 - 2012-02-06 ===================================== Merge in upstream changes from bleadperl. Improved locale tests. Major Changes in 0.95 - 2011-11-12 ===================================== Restore compatibility in replacement UNIVERSAL::VERSION with the behavior of Perl 5.14.x, essentially by reverting the changes in https://rt.perl.org/rt3/Ticket/Display.html?id=95544 Fix segfault error with strings that begin with 'v', especially the string 'version'. Resolves: https://rt.cpan.org/Ticket/Display.html?id=72365 Forbid all math operations on version objects in base class (this was already the case for XS code but the pure Perl was lacking). Resolves: https://rt.cpan.org/Public/Bug/Display.html?id=70950 Major Changes in 0.94 - 2011-08-21 ===================================== Clarify documentation on advisability of using leading 'v' (it isn't mandatory, but it is much more likely to DTRT). Resolves: https://rt.cpan.org/Public/Bug/Display.html?id=70120 Use a localized DIE handler when attempting to load the XS code, in case the caller has its own DIE handler. Resolves: https://rt.cpan.org/Public/Bug/Display.html?id=70260 Major Changes in 0.93 - 2011-07-27 ===================================== Fix problem with UNIVERSAL::VERSION noted by Father Chrysostomos. Major Changes in 0.92 - 2011-07-26 ===================================== Forbid negative versions. Make replacement UNIVERSAL::VERSION return the original $VERSION scalar if called without a requested version. Resolves https://rt.perl.org/rt3/Ticket/Display.html?id=95544 Rewrite code so that we just override all subs for Perl >= 5.9.0 (when version.pm was added to the core). Major Changes in 0.91 - 2011-06-05 ===================================== Fix compilation/linking on Strawberry Perl, resolves https://rt.cpan.org/Ticket/Display.html?id=68611 Major Changes in 0.90 - 2011-06-01 ===================================== Make all tests pass even with older Test::More releases. Resolves https://rt.cpan.org/Ticket/Display.html?id=68588 Major Changes in 0.89 - 2011-05-31 ===================================== Change behavior of pure Perl qv/declare to match the core/XS behavior; do not use parent's new() class for derived classes. This breaks encapsulation but I can justify it because qv/declare is a very specific thing that shouldn't be casually overridden (unless you do it directly in the subclass). Major Changes in 0.88 - 2010-12-19 ===================================== Fix Makefile.PL to make Strawberry Perl happy. Resolves: https://rt.cpan.org/Public/Bug/Display.html?id=63991 Major Changes in 0.87 - 2010-12-09 ===================================== Remove Build.PL since there are modules in the Module::Build tool chain that require version.pm, leading to circular dependencies. This also allows Module::Build itself to depend on version.pm. Major Changes in 0.86 - 2010-11-26 ===================================== is_strict/is_lax were not exported correctly (which no one noticed). Also pull in strict/lax tests from core. Major Changes in 0.85 - 2010-10-25 ===================================== Don't include MYMETA.yml file in distro Major Changes in 0.84 - 2010-10-24 ===================================== Restore public API vcmp() broken in 0.83 Major Changes in 0.83 - 2010-10-17 ===================================== Changed vverify API (David Golden). Improved heuristic for non-magical v-strings (Perl 5.6.0-5.8.0). Install in proper patch post-@INC reordering. Major Changes in 0.82 - 2010-04-13 ===================================== Still more changes to sync with Perl 5.12.0-as-released. Rewritten POD thanks to many hands, but mostly David Golden. Vastly improved Regex definitions from Zephram. Major Changes in 0.81 - 2010-02-01 ===================================== Merge in changes from bleadperl that will be part of Perl 5.12.0. Completely rewrite pure Perl code to operate exactly like the XS code, through the creation of a character-array class called charstar. Now the pure Perl code and XS code can be more easily be synchronized. Major Changes in 0.80 - 2010-01-21 ===================================== No outwardly visible changes. This release is to fix an assertion error with certain picky/older compilers. NOTE: this is not the version object code that will be part of Perl 5.12.0, which will be released shortly as 0.81. Major Changes in 0.79 - 2010-01-03 ===================================== No outwardly visible changes. This release is to match the code that will part of Perl 5.12.0, but which doesn't affect the external API of the CPAN release. Major Changes in 0.78 - 2009-10-12 ===================================== More changes to improve the non-magic v-string heuristics, this time affecting both the pure Perl and XS backends. NOTE: these fixes only matter if you are running Perl 5.6.x to 5.8.0 (inclusive). Beginning with Perl 5.8.1, v-strings are now magical and version.pm no longer has to guess. Resolves: https://rt.cpan.org/Ticket/Display.html?id=50347 Also resolve the issue where attempting to install CPAN releases on top of core releases (e.g. 5.10.0 and 5.10.1) would not DTRT. Resolves: https://rt.cpan.org/Ticket/Display.html?id=49667 Major Changes in 0.7702 - 2009-09-07 ===================================== Add additional contraints to the code which tries to guess whether something is a v-string or not for Perl 5.6.0 through 5.8.0 (inclusive). Resolves: https://rt.cpan.org/Ticket/Display.html?id=49348 Major Changes in 0.7701 - 2009-07-28 ===================================== Special RHEL4.x/Fedora4.x Are Too Stupid to Live Release. Those distros have never updated beyond Perl 5.8.5/5.8.6 respectively. Consequently, they contain a complete broken Test::More::use_ok which doesn't load the package into the correct namespace: https://rt.cpan.org/Ticket/Display.html?id=48268 thus causing mysterious test failures. No version.pm code was changed at all. :( Major Changes in 0.77 - 2009-07-26 =================================== Complete POD rewrite to document common usage in version.pod and put all of the implementation details into version::Internals. Resolve a number of RT tickets: RT#48135 - Compilation failure using MS VC++ 7.0. RT#47980 - Remove need for runtime class loading in pure Perl code RT#46921 - locale and eval action at a distance. RT#45241 - mistaken regex to convert large exponential numbers to non-exponential form before scanning. Please read the POD documentation for usage/details. See the CHANGES file for full details of all changes to the module behavior. INSTALLATION To install this module type the following: $ perl Makefile.PL $ make $ make test # make install This release includes an optional pure Perl implementation (in case you don't have a C-compiler or if some reason you want your code to be much slower). You can test it by replacing the first line above with: $ perl Makefile.PL --perl_only and it will install the Perl only version. DEPENDENCIES The same C compiler used to build Perl (or not). Module::Build 0.2611 or better. Module::Build installs fine under 5.005_03 or better, though the optional dependency Archive::Tar doesn't. If you install Module::Build without any of the optional dependencies, you can safely install version.pm. COPYRIGHT AND LICENCE This module can be distributed under the same terms as Perl.
