+	- "improve portability to Gentoo" - gentoo manages to put perl variables
+          in memory areas that are farther than 2gb apart, which the jit couldn't
+          handle and barfed. now it's just a bit slower on gentoo.
+
+6.01  Sun Jul  3 12:31:14 CEST 2011
+	- workarounds are good, but the test for whether pthreads are used
+          was not good. thisone should be better.
+        - check differently whether gcc generates cfi instructions itself.
+
+6.0   Wed Jun 29 19:43:35 CEST 2011
+	- INCOMPATIBLE CHANGE: unreferenced coro objects will now be
+          destroyed and cleaned up automatically (e.g. async { schedule }).
+        - implement a JIT compiler for part of the thread switch code,
+          which gives a 50% speed improvement on threaded perls, and
+          about 4% on non-thraeded perls (so threaded perls now finally
+          reach about half the speed of non-threaded perls).
+        - slightly modernise Coro::Intro, add section about rouse functions.
+        - avoid DEFSV and ERRSV, giving another 10% improvement
+          in thread switching.
+        - Coro::State->is_destroyed is now called is_zombie.
+        - implement a Coro->safe_cancel method that might fail, but
+          cancels in a "safer" way if it succeeds.
+        - add preliminary support for DEBUGGING perls.
+        - get rid of two hash-accesses when initialising a new Coro - this
+          speeds up coro creation by almost a factor of two.
+        - croak when a coro that is being cancelled tries to block
+          (e.g. while executing a guard block), instead of crashing or
+          deadlocking.
+        - use a more robust and also faster method to identify Coro::State
+          objects - speeds up everything a bit.
+	- implement Coro->cancel in XS for a 20% speed improvement, and to
+          be able to implement mutual cancellation.
+	- speed up context switches by a percent or two by more efficiently
+          allocating context stack entries.
+        - implement Coro->join and Coro->on_destroy in XS for a speedup and
+          a reduction in memory use.
+        - cancelling a coro while it itself is cancelling another coro is
+          now supported and working, instead of triggering an assertion.
+	- be a bit more crash-resistant when calling (buggy) on_destroy
+          callbacks (best effort).
+        - move on_destroy into the slf_frame, to allow extension slf
+          functions to have destructors.
+        - get rid if coro refcounting - simply crash in other interpreter
+          threads by nulling the pointers on clone.
+        - simplify warn/die hook handling when loading Coro - the convoluted
+          logic seems to be no longer neccessary.
+        - use libecb instead of our own home-grown gcc hacks.
+        - document alternatives to Coro::LWP. Please use them :)
+        - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
+          sigaltstack. Really. wine suffers from it, erlang suffers from it,
+          and it's known since at least 2006.
+
+5.372 Wed Feb 23 06:14:30 CET 2011
+	- apparently mingw doesn't provide a working gettimeofday, try to
+          work around that by relying on Time::HiRes (indirectly brought to
+          my attention by Max Maischein).
+        - fix some portability issues when Time::HiRes was used.
+
+5.371 Mon Feb 21 14:36:08 CET 2011
+	- backport to windows process emulation code again.
+
+5.37  Sat Feb 19 07:49:44 CET 2011
+	- add a big "Coro thread life cycle" section to "man Coro".
+	- try a tentative workaround against the breakage that 5.13 has
+          introduced without depreciation period. sigh.
+        - no longer use Time::HiRes if gettimeofday is available, which
+          saves quite a lot of memory.
+
+5.36  Sun Feb 13 05:33:41 CET 2011
+	- automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
+          Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
+          method call.
+        - undocument Coro::Timer::sleep and obsolete whole module.
+        - optimise Coro::Timer::timeout memory and cpu usage.
+        - slightly updated Coro::Intro for recent changes.
+        - do not initialise PL_dirty anymore.
+
+5.25  Thu Nov 11 01:08:39 CET 2010
+	- try a different approach on netbsd - netbsd 5 finally has marginally
+          working pthreads, but still broken ucontext/sigaltstack.
+        - openbsd 4.8 finally got their act together, Coro works out of the box
+          with asm, setjmp and pthreads (no change, just informational).
+
+5.24  Sat Oct 23 11:27:12 CEST 2010
+	- port to the EV 4.0 API.
+	- work around bugs in mingw32, making strawberry perl work
+          out of the box.
+	- correctly modify Coro::AIO function prototypes
+          so that they reflect the "no optional parameters" rule.
+	- "ported" libcoro to C++.
+
+5.23  Mon May 17 18:50:42 CEST 2010
 	- be more resistant to ordering changes when initialising
           Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
           Waldorf).
