They used to + be lost when the 'free' callback was invoked at the end of an + eval block or string. + + Fix : The 'reset RMG flag' workaroundn used to allow wizards with + both 'uvar' and 'clear' magics to be cast onto a hash, has been + made thread-safe. + +0.50 2012-06-24 23:00 UTC + + Fix : Less memory is leaked when a wizard is freed during global + destruction, or when an exception is thrown from a 'free' + callback. + + Fix : [RT #77991] : t/17-ctl.t fails on perl 5.14 and 5.16. + This was actually an issue with ActivePerl, and this test + has learned to cope with it. + Thanks Gisle Aas for reporting. + + Tst : t/35-stash.t has been taught about perl 5.17.1. + + Doc : Many clarifications. + +0.49 2012-06-05 21:40 UTC + This is a maintenance release.

This (should) fix RT #51483. + Thanks Christian Walde for helping to reproduce this failure + and extra testing. + + Rem : Support for development perls from the 5.11 branch but older + than the 5.11.0 release was removed. This could cause more + recent setups to fail. + + Tst : Threads tests are now only run on perl 5.13.4 and higher. + They could segfault randomly because of what seems to be an + internal bug of Perl, which has been addressed in 5.13.4. + There is also an environment variable that allows you to + forcefully run those tests, but it should be set only for + author testing and not for end users. + +0.43 2010-06-25 23:35 UTC + + Add : The new constant VMG_COMPAT_GLOB_GET tells you whether get magic + is called for globs.

This includes the 'sig' option + to wizard(), the getsig() and gensig() functions, and the SIG_* + constants. + +0.38 2009-10-04 16:10 UTC + + Dep : All the signature-related features are DEPRECATED and will be + removed in december 2009. This includes the 'sig' option to + wizard(), the getsig() and gensig() functions, and the SIG_* + constants. + Afaik those features were never used in real life, and they make + the XS code slow and brittle. If you want your wizards to be + globally available, you'll have to handle that yourself by + storing them in a hash. + + Doc : More examples in a new COOKBOOK section. + + Fix : Compatiblity with the 5.11.0 release. The new compatibility + constant VMG_COMPAT_ARRAY_PUSH_NOLEN_VOID was added to cover + this. + + Fix : Work around Kwalitee test misfailures. + +0.37 2009-08-25 15:25 UTC + + Add : The new constant VMG_FORKSAFE can be tested to know whether the + module will behave nicely when fork()ing. It's currently always + true except on Windows where you need perl 5.10.1 for it to be + true. + + Doc : Nits and clarifications. + +0.36 2009-07-05 16:30 UTC + + Chg : getdata() now returns an empty list when no magic is present. + It used to return undef but did not croak as stated in the doc. + Thanks Matt S. Trout for pointing this out. + + Fix : Building and tests with ActiveState Perl 5.8 build >= 822. + +0.35 2009-05-15 20:50 UTC + This is a maintenance release. Users of 0.34 can skip this update. + + Chg : uvar magic used to be enabled for 5.9.5. It now requires 5.10 or + later. + + Fix : Silence compilation warnings for cxinc(). + + Rem : The workaround introduced in 0.31 for the "Unknown errors" issue + was removed, as regression tests show that 0.34 provides a + better fix. + + Tst : Skip t/40-threads.t on 5.8.x with old versions of threads and + threads::shared. + +0.34 2009-04-19 16:55 UTC + + Fix : Destruction of wizards in require. + + Fix : "panic: restartop" in 5.10 when dieing at compile time triggers + a destructor. + +0.33 2009-03-26 00:00 UTC + + Chg : cast() and getsig() now croak too when an invalid signature is + passed. + + Fix : It was possible to generate with gensig() the same signature + twice before actually defining the wizards. + + Tst : More stash tests. + + Tst : Test when the magic takes place in some cases. + + Tst : Improved coverage for the op object feature. + +0.32 2009-03-01 13:45 UTC + + Chg : dispell() and getdata() now croak when an invalid signature is + passed. + + Doc : More examples and a brand new synopsis. + + Fix : The signature is no longer stored in the mg_private member of + the MAGIC struct. This fixes possible clashes with magics from + other extensions. + + Fix : op info objects weren't blessed into the right class. + + Fix : Races when initializing the op names cache under threads. + +0.31 2009-02-19 23:50 UTC + + Doc : A somewhat better introduction. The FUNCTION section was moved + before CONSTANTS and HISTORY since it's more important. And + 'assignation' is really 'assignment', says Ricardo. :) + + Fix : The op_info features are now thread safe. + + Fix : Segfaults that occured when trying to get the op name during + global destruction. + + Fix : Segfaults and wrong "Unknown error" exceptions that happened + when dieing in require caused a free callback to fire. + Thanks Florian Ragwitz for reporting. + +0.30 2009-02-12 17:05 UTC + + Add : You can now get in all the callbacks either the name or a B::OP + object representing the current op if you pass the new 'op_info' + option to wizard() with respective values VMG_OP_INFO_NAME and + VMG_OP_INFO_OBJECT. + + Doc : Document magic on array/hashes values. + + Fix : Completely skip free callbacks during global destruction. + + Tst : Tests now pass again on 5.8.3 and lower (they were broken since + 0.27). + + Tst : Test magic on symbol table and on array/hash values. + +0.29 2009-02-08 11:10 UTC + + Add : Set $_[2] to the default length for len magic on scalars. + + Chg : Perl 5.8 is required. + + Chg : The CLONE method will no longer be defined for non-threaded + perls. + + Doc : Nits. + + Fix : The logic for turning off the GMAGICAL flag on hashes when no + uvar magic is involved could do nasty things on tied hashes. + + Upd : More resources in META.yml. + +0.28 2009-01-24 17:05 UTC + + Add : The 'copy_key' option to wizard(), that enables the safe edition + of $_[2] in uvar callbacks to redirect actions to another key. + + Fix : Exception objects thrown from callbacks at compile time were not + available in $@. + + Fix : free callbacks triggered during global destruction could lead to + segfaults because the wizard was already freed. + + Fix : Refcount of scalars with free callback. + + Fix : Segfaults when using get or uvar magic simultaneously with clear + magic. + + Doc : The documentation about what the callbacks take and should + return is now somewhat clearer. + +0.27 2009-01-18 23:40 UTC + + Fix : Offset of 1 with len magic on scalars. + + Fix : Segfaults that seem to happen when one croak in a callback at + compile time (thanks Ash Berlin for the testcase). + + Upd : Resources in META.yml (Florian Ragwitz) + + Tst : Large cleanup resulting in a wider set of tested behaviours. + +0.26 2008-11-29 22:05 UTC + + Fix : Leaks of cloned coderefs that access lexicals. + + Fix : Building with maint-5.8 and blead (thanks Andreas Koenig). + +0.25 2008-11-12 19:40 UTC + + Fix : Compatibility with 5.8.9. + + Fix : Old Pod::Coverage don't ignore CLONE. + + Upd : META.yml spec updated to 1.4. + +0.24 2008-10-12 14:55 UTC + + Fix : Really fix it. + +0.23 2008-10-11 17:25 UTC + + Fix : Building on perls with multiplicity but not ithreads. + +0.22 2008-09-29 19:40 UTC + + Doc : Explain how magic differs from overloading. + + Fix : Disable thread safety for perl 5.8 on Windows.

The VMG_COMPAT_SCALAR_LENGTH_NOLEN + constant was added to cover this. + + Tst : More tests for t/22-len.t. + +0.14 2008-03-24 12:35 UTC + + Fix : t/16-huf.t failures on Solaris and FreeBSD caused by not + updating mg->mg_ptr after Renew-ing it on dispell. + + Fix : Undefining MGf_DUP caused the wizard's magic to be wrongly + initialized. MGf_DUP now appears as true from the user point of + view, but the dup callback isn't actually set. + + Fix : Warnings with blead due to copy callbacks now taking an I32 (API + change #33256). + + Fix : vmg_svt_val() and vmg_uvar_del() aren't required if no uvar + magic is available. + + Tst : Tests now output the version of optional modules loaded. + 0.13 2008-03-19 14:35 UTC + Doc : Link to coverage report. + Fix : Correct dependencies listing in META.yml.
