+ + Fix : [RT #64435] : Hangs with File::Copy in Config.pm.
+ This was actually a regression introduced together with the new
+ peephole optimizer strategy, and that caused the pragma to hang
+ on constructs like "for (;;) { ... }".
+ Thanks Michael Schilli for reporting.

+ + Chg : perl 5.8.3 is required.
+ + Doc : Complements and clarifications.
+ + Fix : Segmentation faults and misbehaviours in threaded applications.
+ + Fix : Compatibility with perl 5.13.7.
+ Thanks Andreas J. König for reporting and Andrew Main for
+ providing a fix.
+ + Fix : Broken linkage on Windows with gcc 3.4, which appears in
+ particular when using ActivePerl's default compiler suite.
+ For those setups, the autovivification shared library will now
+ be linked against the perl dll directly (instead of the import
+ library).
+ + Opt : The pragma takes slightly more time at compile-time, but is
+ slightly faster at run-time.
+ + Tst : Lengthy tests have been ported to Test::Leaner, making the
+ whole test suite about 50% faster.
+ + 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.

+ + Add : The A_THREADSAFE and A_FORKSAFE constants.
+ + Fix : [RT #56870] : "no autovivification" vs Regexp::Common.
+ This was a bug in how tied arrays and hashes were handled.
+ Thanks Michael G. Schwern for reporting.
+ + Fix : Scope leaks under perl 5.8-5.10.0.
+ + Fix : Segfaults when first loading the pragma from inside a thread.

+ + Fix : [RT #55154] : Crashes and assertion failures when deparsing and
+ re-eval-uating some code compiled while autovivification was in
+ use.
+ Thanks Michael G. Schwern for reporting.
+ + Fix : [RT #53647] : "leys" typo in pod.
+ Thanks Hinrik Orn Sigurdsson for reporting.

+ + Add : Array and hash slices are now handled by the pragma.
+ + Fix : Work around Kwalitee test misfailures.
+
+0.03 2009-06-23 22:20 UTC
+ + Add : Handle old-fashion dereferencing (like $$hashref{key}).
+ + Chg : Aliasing constructs (for ($x{foo}) { ... }) are now covered by
+ the 'store' category (and no longer the 'fetch' one). This is
+ because there's no way to know at compile-time if the alias
+ will be assigned to.
+ + Fix : Quadratic complexity at compile-time.
+ + Fix : Segfaults when dereferencing globals.
+ + Fix : Segfaults on big-endian systems.
+ + Tst : Really test plain arrays and hashes.
+ + Tst : Improved coverage.
+
+0.02 2009-06-17 18:05 UTC
+ + Add : 'fetch' also applies to aliasing ("for ($hashref->{key}) { }").
+ + Fix : Don't segfault on "keys/values %$hashref", and don't vivify if
+ 'fetch' is set.
+ + Fix : Plain dereferencing shouldn't have a different behaviour when
+ the pragma is in use.
+ + Tst : Improved coverage.
