 Revision history for Scope-Upper
 
+0.18    2011-10-10 20:50 UTC
+        + Add : The uid() function returns an unique identifier for each dynamic
+                scope. The validate_uid() function can be used to check whether
+                one such identifier is valid (i.e. that the scope it refers to
+                is still alive).
+        + Chg : It is no longer possible on perl 5.6 to call goto() in an
+                uplevel callback to replace the uplevel call. This change was
+                needed in order to ensure consistency between platforms
+                regarding to the following fix just below.
+        + Fix : The uplevel() tests now pass on Windows.
+                Thanks C.H. Kang for bringing this to my attention.

+        + Fix : uplevel() will now use the correct pad when executing its
+                callback. This fixes at least two issues :
+                - closures defined inside the uplevel callback can now correctly
+                access lexicals from inside and outside the callback.
+                - state variables in the uplevel callback now work properly.
+        + Fix : It is now generally possible to call goto() in the uplevel'd
+                code to replace the uplevel stack frame. There are two cases
+                for which it is still not possible :
+                - if -D flags were set when running perl (as in "perl -Dt ...").
+                - if the perl runloop has been replaced with a custom one by
+                another module.
+                If uplevel() detects that the replacement code contains a goto
+                statement, and is in one of those two cases, then it will refuse
+                to execute the callback and throw an exception.
+                Note that this fix implies a run-time overhead of uplevel()
+                proportional to the size of the the callback in every case
+                (with a small ratio), and proportional to the size of ALL the
+                code executed as the result of the uplevel call (including
+                subroutine calls inside the callback) when a goto statement is
+                found in the uplevel callback.
+        + Fix : uplevel() has been taught how to handle XS callbacks properly.
+        + Fix : The cause of "Attempt to free unreferenced scalar" warnings
+                when using uplevel() has been addressed.
+        + Fix : [RT #71212] : build failure on Windows.
+                The module does no longer rely on calling Perl_cv_clone, which
+                isn't exported.
+                Thanks C.H. Kang for reporting.

+        + Add : uplevel($code, @args, $cxt) executes $code with arguments @args
+                in the upper context pointed by $cxt.
+                This is an XS version of the well-known uplevel() routine from
+                Sub::Uplevel. There are a few differences between both
+                implmentations that are listed in the documentation.
+                The XS version is roughly 10 times faster than the pure-Perl
+                version.
+
+0.15    2011-08-24 14:20 UTC
+        + Fix : Localizing subroutines in an higher scope will now correctly
+                update the method cache.
+
+0.14    2011-02-27 00:00 UTC
+        + Fix : [RT #64997] : Compatibility with perl 5.13.10.
+                Thanks Dave Mitchell for the notice.
+        + Tst : Lengthy tests have been ported to Test::Leaner, making the
+                whole test suite about 50% faster.
+
 0.13    2010-12-20 01:00 UTC
         + Fix : [RT #61904] : Stack corruption when using unwind() under
                 Devel::NYTProf.
