3 0.64 2024-03-18 23:20 UTC
4 This is a maintenance release. The code contains no functional change.
5 Satisfied users of version 0.63 can skip this update.
6 + Add : Contributing guidelines are now listed in the new
8 + Fix : [RT #151104] : fix for t/18-opinfo.t broken under blead
9 Some optimization in core made t/18-opinfo.t fail since perl
10 5.39.7, but that was reverted before 5.40 was released.
11 This fix will make this test pass even when the optimization
12 is reinstantiated after release freeze.
13 Thanks David Mitchell for reporting and providing a fix.
15 0.63 2022-09-20 21:45 UTC
16 This is a maintenance release. The code contains no functional change.
17 Satisfied users of version 0.62 can skip this update.
18 + Fix : [RT #144052] : Add support for 5.37.3s PADSV_STORE optimization
19 B.pm-related tests have been taught about this new thing.
20 Thanks Richard Leach for contributing a patch.
23 0.62 2017-11-04 16:35 UTC
24 + Fix : [RT #123314] : Compatibility with CV-in-stash optimisation
25 Thanks Father Chrysostomos for reporting and contributing a
28 0.61 2017-01-24 15:30 UTC
29 + Fix : [RT #115792] : Latest blead stack unwind work causes infloop
31 A change in how the core frees temporary values after eval
32 interacted badly with Variable::Magic and caused infinite loops
33 when a free callback was attached to a wizard. This change was
34 temporarily reverted, but is going to be reinstated, and
35 Variable::Magic is now able to play nicely when this happens.
36 Thanks Peter Rabbitson for reporting and David Mitchell for
40 0.60 2016-09-06 22:30 UTC
41 + Chg : A large chunk of boilerplate XS code, which is also used in
42 other XS modules, has been factored out of the main .xs file
43 to a collection of .h files in the xsh subdirectory.
44 + Fix : [RT #128989] : Bleadperl v5.25.3-266-g1d7e644 breaks V::M.
45 Len magic is no longer called for negative array indices
46 fetches, so the relevant tests are now skipped.
47 Thanks Andreas Koenig for reporting.
49 0.59 2015-10-05 19:05 UTC
50 + Chg : The magic callbacks are now always executed in a new stack.
51 This should have no negative impact (performance-wise or
52 behaviour-wise) on your code, but may actually fix some obscure
54 + Fix : [RT #107294] : Crash during install of Variable-Magic-0.58
55 running "t\18-opinfo.t".
56 A recent change in the core implementation of transliterations
57 caused an undefined behaviour when it interacted with this
58 module, which resulted in visible stack corruption on Win32
59 perls compiled with MSVC when the op_info feature was enabled.
60 This was fixed by using a separate stack for the magic
62 Thanks Peter Stokes for reporting and providing greatly
64 + Fix : The object op_info feature will now handle correctly Unicode
65 transliteration, multideref and custom ops.
67 0.58 2015-07-21 16:00 UTC
68 + Add : If a non-len magic callback returns a reference, it will now
69 only be freed at the end of the statement that caused the
70 magic to trigger. This allows the user to attach free magic
71 (or a plain destructor) to a token returned from the callbacks
72 in order to defer an action after the magic is processed by
74 + Fix : Test failures of threads tests on systems with harsh resource
75 constraints causing the threads to exit() during run.
77 0.57 2015-04-17 15:20 UTC
78 + Chg : The new environment variable to enable thread tests on older
79 perls is PERL_FORCE_TEST_THREADS. Note that this variable
80 should only be turned on by authors.
81 + Fix : Segfaults when the module is loaded by several threads (or
82 Windows emulated processes) ran in parallel.
83 + Fix : Segfaults when the module is loaded in a thread, which spawns
84 itself a new thread, and that child thread outlives its parent.
85 + Fix : Small memory leaks of structures required for thread safety.
86 + Fix : Update the Windows ActivePerl + gcc 3.4 workaround for
87 ExtUtils::MakeMaker 7.04. Thanks Christian Walde for reporting
88 and feedback on this issue.
89 + Tst : The global destruction test will now be exercised on any perl
90 that has DEBUGGING set.
91 + Tst : Optional capturing tests in t/17-ctl.t that were only run when
92 Capture::Tiny was present were converted to an IPC::Open3
93 based helper and will now be run everywhere.
95 0.56 2015-03-11 15:15 UTC
96 + Fix : [RT #101410] : Install fails in blead
97 Even though the change that caused this error was reverted from
98 blead, lvalue uses of ERRSV have been removed from this module
99 so that there will be no breakage when this change is possibly
100 reintroduced in the following months.
101 Thanks Dave Rolsky for reporting.
102 + Tst : $ENV{$Config{ldlibpthname}} is now preserved on all platforms,
103 which will address failures of t/17-ctl.t with unusual
104 compilers (like icc) that link all their compiled objects to
106 + Tst : The global destruction test is now only run on perl 5.13.4 and
107 higher, and only if either Perl::Destruct::Level is installed
108 or PERL_DESTRUCT_LEVEL is set and the perl is a debugging perl.
109 This will solve rare crashes of t/15-self.t on perl 5.13.3 and
112 0.55 2014-10-20 23:45 UTC
113 + Fix : [RT #99319] : t/18-opinfo.t: test failure due to change in
115 The new METHOP op class added in perl 5.21.5 is now supported.
116 Thanks James E Keenan for reporting.
118 0.54 2014-09-22 17:30 UTC
119 + Add : The new constant VMG_COMPAT_CODE_COPY_CLONE evaluates to true
120 if your perl calls 'copy' magic when a magical code prototype
121 is cloned, which is currently the case for perl 5.17.0 and
123 + Fix : [RT #90205] : copy magic on subs puts raw CV in $_[3]
124 $_[3] will now contain a reference to the cloned code when
125 'copy' magic is called for a coderef.
126 Thanks Lukas Mai for reporting.
127 + Fix : t/35-stash.t has been taught about perl 5.21.4.
128 + Fix : Tests using run_perl() in t/17-ctl.t will no longer fail on
131 0.53 2013-09-01 17:50 UTC
132 This is a maintenance release. The code contains no functional change.
133 Satisfied users of version 0.52 can skip this update.
134 + Fix : [RT #86338] : typo fix.
135 Thanks dsteinbrunner@pobox.com for the patch.
136 + Tst : Author tests are no longer bundled with this distribution.
137 They are only made available to authors in the git repository.
139 0.52 2012-11-05 02:30 UTC
140 + Add : The new constant VMG_COMPAT_SCALAR_NOLEN evaluates to true
141 when your perl does not call 'len' magic for scalars, which
142 is the case for perl 5.17.4 and above.
143 This fixes RT #80388.
144 + Tst : t/35-stash.t has been taught about perl 5.17.4.
145 + Tst : Author tests overhaul.
147 0.51 2012-08-18 15:00 UTC
148 + Fix : It is now safe to call dispell() from inside 'free', 'copy' and
149 'uvar' callbacks to dispell the magic currently in use.
150 Thanks Clinton Gormley for reporting.
151 + Fix : Exceptions thrown from inside a 'free' callback are now always
152 consistently propagated outside of the callback. They used to
153 be lost when the 'free' callback was invoked at the end of an
154 eval block or string.
155 + Fix : The 'reset RMG flag' workaroundn used to allow wizards with
156 both 'uvar' and 'clear' magics to be cast onto a hash, has been
159 0.50 2012-06-24 23:00 UTC
160 + Fix : Less memory is leaked when a wizard is freed during global
161 destruction, or when an exception is thrown from a 'free'
163 + Fix : [RT #77991] : t/17-ctl.t fails on perl 5.14 and 5.16.
164 This was actually an issue with ActivePerl, and this test
165 has learned to cope with it.
166 Thanks Gisle Aas for reporting.
167 + Tst : t/35-stash.t has been taught about perl 5.17.1.
168 + Doc : Many clarifications.
170 0.49 2012-06-05 21:40 UTC
171 This is a maintenance release. The code contains no functional change.
172 Satisfied users of version 0.48 can skip this update.
173 + Fix : [RT #77644] : t/17_ctl.t fails in test 44 since 5.17.0.
174 This test has been taught about perl 5.17.0.
175 Thanks Reini Urban for reporting.
176 + Tst : t/99-kwalitee.t will be skipped when only problematic versions
177 of its dependencies are available.
179 0.48 2012-02-17 23:40 UTC
180 + Add : You can now pass a reference to undef as the magic callback in
181 order to install a no-op callback.
182 Thanks Florian Ragwitz for the suggestion.
184 0.47 2011-10-27 16:55 UTC
185 + Add : The new constant VMG_COMPAT_HASH_DELETE_NOUVAR_VOID evaluates
186 to true when "delete $hash{key}" does not call 'delete' uvar
187 magic in void context.
188 + Chg : The MAGIC tokens created by this module no longer use the
189 mg_private member for storing a "magical" signature.
190 + Fix : Triggering magic in a thread on a variable cloned from the main
191 interpreter, and when the wizard already went out of scope,
192 will not segfault anymore.
193 + Opt : The pointer table is no longer needed to ensure thread safety.
194 The size of the object code is about 8% smaller for threaded
196 + Tst : Threads tests will not fail anymore if resources constraints
197 prevent the system from creating all the required threads.
199 0.46 2011-01-23 16:45 UTC
200 + Fix : [RT #64866] : Assertion failure with perl 5.13.9.
201 The real problem was that dispell() wasn't properly resetting
202 the magical sv flags, which became visible in the test suite
203 only with perl 5.13.9.
204 Thanks Joshua ben Jore for reporting.
206 0.45 2010-11-21 23:15 UTC
207 This is a maintenance release. The code contains no functional change.
208 Users of 0.44 can skip this update.
209 + Doc : C++ compilers are officially NOT supported.
210 + Doc : The minimum perl 5.10.0 requirement for uvar magic has been
212 Thanks Peter Rabbitson for pointing this out and contributing a
214 + Tst : Tune for perl 5.13.7.
215 + Tst : Capture::Tiny will be used in t/17-ctl.t if and only if it can
216 capture a simple run.
218 0.44 2010-09-24 19:10 UTC
219 + Fix : Broken linkage on Windows with gcc 3.4, which appears in
220 particular when using ActivePerl's default compiler suite.
221 For those setups, the Variable::Magic shared library will now
222 be linked against the perl dll directly (instead of the import
223 library). This (should) fix RT #51483.
224 Thanks Christian Walde for helping to reproduce this failure
226 + Rem : Support for development perls from the 5.11 branch but older
227 than the 5.11.0 release was removed. This could cause more
228 recent setups to fail.
229 + Tst : Threads tests are now only run on perl 5.13.4 and higher.
230 They could segfault randomly because of what seems to be an
231 internal bug of Perl, which has been addressed in 5.13.4.
232 There is also an environment variable that allows you to
233 forcefully run those tests, but it should be set only for
234 author testing and not for end users.
236 0.43 2010-06-25 23:35 UTC
237 + Add : The new constant VMG_COMPAT_GLOB_GET tells you whether get magic
238 is called for globs. It's true starting perl 5.13.2.
239 + Chg : All callbacks are now called within an eval-like context.
240 Only free callbacks used to be called that way.
241 + Fix : Some exceptions thrown from a free callback could be lost.
242 + Fix : Croak messages could sometimes be repeated several times.
243 + Fix : t/41-clone.t segfaulting with perl 5.13.2.
245 0.42 2010-05-19 00:15 UTC
246 This is a maintenance release. The code contains no functional change.
247 Users of 0.41 can skip this update.
248 + Fix : Test failures with perl 5.13.
249 + Tst : Improve coverage.
251 0.41 2010-03-15 17:35 UTC
252 + Doc : Tweaks and fixups.
254 + Fix : Compatibility with the soon-to-be-released perl 5.12.0.
255 + Fix : Correctly propagate the errors thrown when variable destruction
256 happens at compile-time and not from inside eval STRING.
257 Thanks Florian Ragwitz and Ash Berlin for reporting.
259 0.40 2010-01-06 23:20 UTC
260 + Fix : Possible memory miswrites when passing data arguments to cast().
261 + Fix : Minor C portability tweaks.
263 0.39 2009-12-01 00:05 UTC
264 + Add : You can use a function name as a callback by passing a string
265 reference to wizard() instead of a code reference.
266 + Fix : Compatiblity with perl 5.11.1 and 5.11.2.
267 + Fix : Scalars stored into the data slot no longer leak.
268 + Fix : Thread destruction should not segfault anymore.
269 + Opt : As a result of removing the deprecated features, less memory is
270 used for both threaded (a pointer table is used instead of a
271 hash) and non-threaded (no global structure is needed anymore)
273 + Rem : As advertised in the precendent version, all the signature
274 related features were removed. This includes the 'sig' option
275 to wizard(), the getsig() and gensig() functions, and the SIG_*
278 0.38 2009-10-04 16:10 UTC
279 + Dep : All the signature-related features are DEPRECATED and will be
280 removed in december 2009. This includes the 'sig' option to
281 wizard(), the getsig() and gensig() functions, and the SIG_*
283 Afaik those features were never used in real life, and they make
284 the XS code slow and brittle. If you want your wizards to be
285 globally available, you'll have to handle that yourself by
286 storing them in a hash.
287 + Doc : More examples in a new COOKBOOK section.
288 + Fix : Compatiblity with the 5.11.0 release. The new compatibility
289 constant VMG_COMPAT_ARRAY_PUSH_NOLEN_VOID was added to cover
291 + Fix : Work around Kwalitee test misfailures.
293 0.37 2009-08-25 15:25 UTC
294 + Add : The new constant VMG_FORKSAFE can be tested to know whether the
295 module will behave nicely when fork()ing. It's currently always
296 true except on Windows where you need perl 5.10.1 for it to be
298 + Doc : Nits and clarifications.
300 0.36 2009-07-05 16:30 UTC
301 + Chg : getdata() now returns an empty list when no magic is present.
302 It used to return undef but did not croak as stated in the doc.
303 Thanks Matt S. Trout for pointing this out.
304 + Fix : Building and tests with ActiveState Perl 5.8 build >= 822.
306 0.35 2009-05-15 20:50 UTC
307 This is a maintenance release. Users of 0.34 can skip this update.
308 + Chg : uvar magic used to be enabled for 5.9.5. It now requires 5.10 or
310 + Fix : Silence compilation warnings for cxinc().
311 + Rem : The workaround introduced in 0.31 for the "Unknown errors" issue
312 was removed, as regression tests show that 0.34 provides a
314 + Tst : Skip t/40-threads.t on 5.8.x with old versions of threads and
317 0.34 2009-04-19 16:55 UTC
318 + Fix : Destruction of wizards in require.
319 + Fix : "panic: restartop" in 5.10 when dieing at compile time triggers
322 0.33 2009-03-26 00:00 UTC
323 + Chg : cast() and getsig() now croak too when an invalid signature is
325 + Fix : It was possible to generate with gensig() the same signature
326 twice before actually defining the wizards.
327 + Tst : More stash tests.
328 + Tst : Test when the magic takes place in some cases.
329 + Tst : Improved coverage for the op object feature.
331 0.32 2009-03-01 13:45 UTC
332 + Chg : dispell() and getdata() now croak when an invalid signature is
334 + Doc : More examples and a brand new synopsis.
335 + Fix : The signature is no longer stored in the mg_private member of
336 the MAGIC struct. This fixes possible clashes with magics from
338 + Fix : op info objects weren't blessed into the right class.
339 + Fix : Races when initializing the op names cache under threads.
341 0.31 2009-02-19 23:50 UTC
342 + Doc : A somewhat better introduction. The FUNCTION section was moved
343 before CONSTANTS and HISTORY since it's more important. And
344 'assignation' is really 'assignment', says Ricardo. :)
345 + Fix : The op_info features are now thread safe.
346 + Fix : Segfaults that occured when trying to get the op name during
348 + Fix : Segfaults and wrong "Unknown error" exceptions that happened
349 when dieing in require caused a free callback to fire.
350 Thanks Florian Ragwitz for reporting.
352 0.30 2009-02-12 17:05 UTC
353 + Add : You can now get in all the callbacks either the name or a B::OP
354 object representing the current op if you pass the new 'op_info'
355 option to wizard() with respective values VMG_OP_INFO_NAME and
357 + Doc : Document magic on array/hashes values.
358 + Fix : Completely skip free callbacks during global destruction.
359 + Tst : Tests now pass again on 5.8.3 and lower (they were broken since
361 + Tst : Test magic on symbol table and on array/hash values.
363 0.29 2009-02-08 11:10 UTC
364 + Add : Set $_[2] to the default length for len magic on scalars.
365 + Chg : Perl 5.8 is required.
366 + Chg : The CLONE method will no longer be defined for non-threaded
369 + Fix : The logic for turning off the GMAGICAL flag on hashes when no
370 uvar magic is involved could do nasty things on tied hashes.
371 + Upd : More resources in META.yml.
373 0.28 2009-01-24 17:05 UTC
374 + Add : The 'copy_key' option to wizard(), that enables the safe edition
375 of $_[2] in uvar callbacks to redirect actions to another key.
376 + Fix : Exception objects thrown from callbacks at compile time were not
378 + Fix : free callbacks triggered during global destruction could lead to
379 segfaults because the wizard was already freed.
380 + Fix : Refcount of scalars with free callback.
381 + Fix : Segfaults when using get or uvar magic simultaneously with clear
383 + Doc : The documentation about what the callbacks take and should
384 return is now somewhat clearer.
386 0.27 2009-01-18 23:40 UTC
387 + Fix : Offset of 1 with len magic on scalars.
388 + Fix : Segfaults that seem to happen when one croak in a callback at
389 compile time (thanks Ash Berlin for the testcase).
390 + Upd : Resources in META.yml (Florian Ragwitz)
391 + Tst : Large cleanup resulting in a wider set of tested behaviours.
393 0.26 2008-11-29 22:05 UTC
394 + Fix : Leaks of cloned coderefs that access lexicals.
395 + Fix : Building with maint-5.8 and blead (thanks Andreas Koenig).
397 0.25 2008-11-12 19:40 UTC
398 + Fix : Compatibility with 5.8.9.
399 + Fix : Old Pod::Coverage don't ignore CLONE.
400 + Upd : META.yml spec updated to 1.4.
402 0.24 2008-10-12 14:55 UTC
403 + Fix : Really fix it.
405 0.23 2008-10-11 17:25 UTC
406 + Fix : Building on perls with multiplicity but not ithreads.
408 0.22 2008-09-29 19:40 UTC
409 + Doc : Explain how magic differs from overloading.
410 + Fix : Disable thread safety for perl 5.8 on Windows. If you want it
411 enabled, reliable feedback is welcome.
413 0.21_02 2008-09-28 23:10 UTC
414 + Fix : Hide previously deleted magic tokens in vmg_svt_free (Yuval
417 0.21_01 2008-09-22 13:25 UTC
418 + Chg : Shrink the context data.
419 + Fix : Enable thread safety features for perls that just lack
421 + Tst : Output threads and threads::shared versions in threads tests.
423 0.20 2008-09-20 23:35 UTC
424 + Fix : The module is now thread safe. You can test if it had been
425 built with thread safety features enabled through the
426 VMG_THREADSAFE constant.
427 + Fix : Correct backtrace when wizard() croaks.
428 + Fix : 'cast $a, undef' should throw an 'invalid wizard' error instead
429 of an 'invalid signature'.
431 0.19 2008-07-05 15:05 UTC
432 + Add : The patchlevel with which the module has been built is now
433 exported with the VMG_PERL_PATCHLEVEL constant.
434 + Chg : Version checking macros overhaul.
435 + Fix : 'uvar' magic should only be enabled in maint-5.10 and higher
436 since it's never going to be backported to 5.8.
437 + Fix : Likewise, the copy callback API change should only be enabled in
439 + Fix : Instead of those ackward fake refcount increments in the wizard
440 destructor, flag the wizard with SVf_BREAK and force temps
441 cleanup. This should fix the wizard destruction for all perls,
442 and solves the leak introduced by the previous solution.
444 0.18 2008-07-04 12:20 UTC
445 + Fix : Enable uvar magic when patchlevel >= 28419.
446 + Fix : Set VMG_COMPAT_ARRAY_PUSH_NOLEN for Windows ActiveState Perl
449 0.17 2008-05-11 09:05 UTC
450 + Fix : 5.8.4 and lower don't have mPUSHi. Gah. Yeah, I know, I should
453 0.16 2008-05-10 22:05 UTC
454 + Add : The samples/copy.pl script.
455 + Chg : The sv_magical() + vmg_mg_magical() combo was simplified into
457 + Tst : t/33-code.t was testing scalars, not code.
458 + Tst : is() and like() are better than ok().
459 + Tst : 100% coverage reached.
461 0.15 2008-04-11 18:25 UTC
462 + Chg : Factor vmg_cb_call{1,2,3}() into one function.
463 + Fix : len magic is no longer called when taking the length() of a
464 magical scalar since p32969. The VMG_COMPAT_SCALAR_LENGTH_NOLEN
465 constant was added to cover this.
466 + Tst : More tests for t/22-len.t.
468 0.14 2008-03-24 12:35 UTC
469 + Fix : t/16-huf.t failures on Solaris and FreeBSD caused by not
470 updating mg->mg_ptr after Renew-ing it on dispell.
471 + Fix : Undefining MGf_DUP caused the wizard's magic to be wrongly
472 initialized. MGf_DUP now appears as true from the user point of
473 view, but the dup callback isn't actually set.
474 + Fix : Warnings with blead due to copy callbacks now taking an I32 (API
476 + Fix : vmg_svt_val() and vmg_uvar_del() aren't required if no uvar
478 + Tst : Tests now output the version of optional modules loaded.
480 0.13 2008-03-19 14:35 UTC
481 + Doc : Link to coverage report.
482 + Fix : Correct dependencies listing in META.yml.
483 + Tst : Improved test coverage.
484 + Tst : Print the patchlevel as a comment.
485 + Tst : Use is() where it's relevant.
486 + Tst : t/16-huf.t now really tests interaction with H::U::FH.

493 + Add : Copy callbacks now receive the current key/index in $_[2].
494 The current value/element is now in $_[3].
495 + Chg : The trigger of copy magic on list assignment with perls greater
496 than 5.10.0 was caused by uvar magic. Hence,
497 VMG_COMPAT_HASH_LISTASSIGN_COPY was removed. Use VMG_UVAR
499 + Fix : Build failures on patched perls.
500 + Tst : Added missing exported symbols to 01-import.t.
502 0.10 2008-02-04 11:30 UTC
503 + Add : New script : samples/vm_vs_tie.pl, that benchmarks our uvar
504 magic versus tied hashes.
505 + Add : The VMG_COMPAT_* constants can be used from userspace to check
506 perl magic abilities.
507 + Fix : Callbacks that returned undef made us croak, breaking the
508 variable behaviour (regression test in 14-callbacks.t).
509 + Fix : uvar callbacks weren't tested for non-NULL-ity before being
510 called (regression test in 28-uvar.t).
511 + Tst : Fix typo in 25-copy.t that prevented Tie::Hash tests to be ran.
513 0.09 2008-02-02 11:30 UTC
514 + Doc : Explicitely say that uvar callbacks are safely ignored for
516 + Doc : Document caveats and fix the usual set of typos.
517 + Fix : vmg_dispell() didn't check if the ext magic were ours when
518 counting wizards that have uvar callbacks, resulting in a
519 possible memory misread.
520 + Fix : getdata() now returns directly the data object, and no longer a
521 copy. This caused a leak.
522 + Tst : Prefix author tests by 9*-.
523 + Tst : New optional author test : 95-portability-files.t, that uses
524 Test::Portability::Files when it's present.
525 + Tst : New test : 14-self.t, that tests application of magic on the
527 + Tst : Move Hash::Util::FieldHash tests out of 11-multiple.t to
530 0.08 2008-02-01 16:55 UTC
531 + Add : copy magic for tied arrays/hashes.
533 + Add : uvar magics : fetch, store, exists, delete for hashes.

539 + Chg : 5.7.3 is now officially required.
540 + Fix : "data" test failures on 5.8.{0,2}.
541 + Fix : Drand01() vs rand().
543 0.05 2007-11-19 09:10 UTC
544 + Fix : 5.10.0_RC1 compatibility fix.

547 + Chg : s/require (XSLoader)/use $1/.
548 + Fix : Tests are now strict.
549 + Fix : Complete dependencies.

552 + Add : Passing the signature of an already defined magic to wizard()
553 now returns the corresponding magic object.
554 + Add : You can pass the numeric signature as the wizard argument of
555 cast(), dispell() and getdata().
556 + Add : Any argument specified after the wizard (or the signature) in a
557 call to cast() is now passed to the private data constructor in
559 + Chg : $_[0] is now always a reference to the magic variable in all
560 callbacks. The reason for changing from the previous behaviour
561 is that one may want to apply the same magic to a plain scalar
562 and to a scalar reference, and needs a way to distinguish
563 between them in the callback (say, ref()).
564 + Fix : Wizard object destruction used not to free the signature.
566 0.02 2007-07-27 13:50 UTC
567 + Fix : In response to test report 548152 :
568 Newx() and SvMAGIC_set() not present on older perls.
569 + Fix : In response to test report 548275 :
570 Since perl 5.9.5, 'clear' magic is invoked when an array is
571 undefined (bug #43357). Moreover, 'len' magic is no longer
572 called by pushing an element since perl 5.9.3.
573 + Fix : Missing glob test in MANIFEST.
