+ Fix : [RT #115792] : Latest blead stack unwind work causes infloop
in a test.
A change in how the core frees temporary values after eval
interacted badly with Variable::Magic and caused infinite loops
when a free callback was attached to a wizard. This change was
temporarily reverted, but is going to be reinstated, and
Variable::Magic is now able to play nicely when this happens.
Thanks Peter Rabbitson for reporting and David Mitchell for
providing a fix.

+ Chg : A large chunk of boilerplate XS code, which is also used in
other XS modules, has been factored out of the main .xs file
to a collection of .h files in the xsh subdirectory.
+ Fix : [RT #128989] : Bleadperl v5.25.3-266-g1d7e644 breaks V::M.
Len magic is no longer called for negative array indices
fetches, so the relevant tests are now skipped.
Thanks Andreas Koenig for reporting.
0.59 2015-10-05 19:05 UTC
+ Chg : The magic callbacks are now always executed in a new stack.
This should have no negative impact (performance-wise or
behaviour-wise) on your code, but may actually fix some obscure
bugs.
+ Fix : [RT #107294] : Crash during install of Variable-Magic-0.58
running "t\18-opinfo.t".
A recent change in the core implementation of transliterations
caused an undefined behaviour when it interacted with this
module, which resulted in visible stack corruption on Win32
perls compiled with MSVC when the op_info feature was enabled.
This was fixed by using a separate stack for the magic
callbacks.
Thanks Peter Stokes for reporting and providing greatly
helpful feedback.
+ Fix : The object op_info feature will now handle correctly Unicode
transliteration, multideref and custom ops.

+ Add : If a non-len magic callback returns a reference, it will now
only be freed at the end of the statement that caused the
magic to trigger. This allows the user to attach free magic
(or a plain destructor) to a token returned from the callbacks
in order to defer an action after the magic is processed by
perl.
+ Fix : Test failures of threads tests on systems with harsh resource
constraints causing the threads to exit() during run.
-------------------
0.57 2015-04-17 15:20 UTC
+ Chg : The new environment variable to enable thread tests on older
perls is PERL_FORCE_TEST_THREADS. Note that this variable
should only be turned on by authors.
+ Fix : Segfaults when the module is loaded by several threads (or
Windows emulated processes) ran in parallel.
+ Fix : Segfaults when the module is loaded in a thread, which spawns
itself a new thread, and that child thread outlives its parent.
+ Fix : Small memory leaks of structures required for thread safety.
+ Fix : Update the Windows ActivePerl + gcc 3.4 workaround for
ExtUtils::MakeMaker 7.04. Thanks Christian Walde for reporting
and feedback on this issue.
+ Tst : The global destruction test will now be exercised on any perl
that has DEBUGGING set.
+ Tst : Optional capturing tests in t/17-ctl.t that were only run when
Capture::Tiny was present were converted to an IPC::Open3
based helper and will now be run everywhere.
0.56 2015-03-11 15:15 UTC
+ Fix : [RT #101410] : Install fails in blead
Even though the change that caused this error was reverted from
blead, lvalue uses of ERRSV have been removed from this module
so that there will be no breakage when this change is possibly
reintroduced in the following months.
Thanks Dave Rolsky for reporting.
+ Tst : $ENV{$Config{ldlibpthname}} is now preserved on all platforms,
which will address failures of t/17-ctl.t with unusual
compilers (like icc) that link all their compiled objects to
their own libraries.
+ Tst : The global destruction test is now only run on perl 5.13.4 and
higher, and only if either Perl::Destruct::Level is installed
or PERL_DESTRUCT_LEVEL is set and the perl is a debugging perl.
This will solve rare crashes of t/15-self.t on perl 5.13.3 and
older.
0.55 2014-10-20 23:45 UTC
+ Fix : [RT #99319] : t/18-opinfo.t: test failure due to change in
perl 5 blead
The new METHOP op class added in perl 5.21.5 is now supported.
Thanks James E Keenan for reporting.
0.54 2014-09-22 17:30 UTC
+ Add : The new constant VMG_COMPAT_CODE_COPY_CLONE evaluates to true
if your perl calls 'copy' magic when a magical code prototype
is cloned, which is currently the case for perl 5.17.0 and
above.
+ Fix : [RT #90205] : copy magic on subs puts raw CV in $_[3]
$_[3] will now contain a reference to the cloned code when
'copy' magic is called for a coderef.
Thanks Lukas Mai for reporting.
+ Fix : t/35-stash.t has been taught about perl 5.21.4.
+ Fix : Tests using run_perl() in t/17-ctl.t will no longer fail on
Android.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.

0.51 2012-08-18 15:00 UTC
+ Fix : It is now safe to call dispell() from inside 'free', 'copy' and
'uvar' callbacks to dispell the magic currently in use.
Thanks Clinton Gormley for reporting.
+ Fix : Exceptions thrown from inside a 'free' callback are now always
consistently propagated outside of the callback. 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

order to install a no-op callback.
Thanks Florian Ragwitz for the suggestion.
0.47 2011-10-27 16:55 UTC
+ Add : The new constant VMG_COMPAT_HASH_DELETE_NOUVAR_VOID evaluates
to true when "delete $hash{key}" does not call 'delete' uvar
magic in void context.
+ Chg : The MAGIC tokens created by this module no longer use the
mg_private member for storing a "magical" signature.
+ Fix : Triggering magic in a thread on a variable cloned from the main
interpreter, and when the wizard already went out of scope,
will not segfault anymore.
+ Opt : The pointer table is no longer needed to ensure thread safety.
The size of the object code is about 8% smaller for threaded
perls.
+ Tst : Threads tests will not fail anymore if resources constraints
prevent the system from creating all the required threads.
Changes from previous:
0.46 2011-01-23 16:45 UTC
+ Fix : [RT #64866] : Assertion failure with perl 5.13.9.
The real problem was that dispell() wasn't properly resetting
the magical sv flags, which became visible in the test suite
only with perl 5.13.9.
Thanks Joshua ben Jore for reporting.

+ Tst : Capture::Tiny will be used in t/17-ctl.t if and only if it can
capture a simple run.
0.44 2010-09-24 19:10 UTC
+ Fix : Broken linkage on Windows with gcc 3.4, which appears in
particular when using ActivePerl's default compiler suite.
For those setups, the Variable::Magic shared library will now
be linked against the perl dll directly (instead of the import
library). 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.

related features were removed. This includes the 'sig' option
to wizard(), the getsig() and gensig() functions, and the SIG_*
constants.
Upstream changes:
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.

Magic is Perl way of enhancing objects. This mechanism let the user
add extra data to any variable and overload syntaxical operations
(such as access, assignation or destruction) that can be applied
to it. With the module Variable::Magic , you can add your own magic
to any variable without the pain of the C API.
