+TODO: swap_sv, maybe add scope_swap_sv?
+TODO: croak when async_pool tries to run canceled thread?
 
+	- safe_cancel no longer croaks when called on already-destroyed
+          thread, but instead "just works".
+
+6.513 Sat Jul 15 01:18:51 CEST 2017
+	- experimental 5.22 comaptibility changes (PadlistNAMES).
+	- removed attributes example and made sure the other examples
+          still work.
+        - fix some statevar types for newer perls, should be of no consequence.
+
+6.512 Fri Jul 14 05:03:17 CEST 2017
+        - seems to pass test suite down till 5.8.9, so make this the
+          minimum requirement in Makefile.PL.
+	- experimental 5.24 compatibility changes (SUB_ARGARRAY).
+        - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
+        - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
+          fortified longjmp variants in some libcs.
+	- re-try JIT allocation without PROT_EXEC, to hopefully improve
+          portability (still doesn't seem to work around broken selinux
+          mmap everywhere).
+        - speling fixes (Xavier Guimard).
+
+6.511 Sun Jun 26 23:44:50 CEST 2016
+	- make it compile with threaded perls again.
+	- simplify and speed up __DIE__ and __WARN__ handling.
+
+6.51 Sat Jun 25 20:57:20 CEST 2016
+	- 6.5 release didn't compile on most older perls due to
+          a logic error enabling experimental 5.24 code for all versions.
+        - since various broken or deficient patches float around
+          to work around the vtbl API breakage in perl, let's provide
+          our own workaround, which seems to be much less invasive
+          and more compatible than the approaches seen so far. YMMV.
+	- work around assertion failure in perl_destruct on 5.24
+          (analyzed by Dave Mitchell).
+
+6.5  Wed Jun 22 22:23:50 CEST 2016
+	- swap_sv swapping order was not symmetrical, causing
+          wrong swaps when swap_sv was used multiple times on the
+          same sv in the same thread.
+        - swap_sv calls can now be undone by calling it again
+          with the same variables.
+        - swap_sv calls will now be undone in async_pool threads.
+	- split Coro::Semaphore::up/adjust into separate xs functions
+          for better error reporting, at slight codesize increase.
+        - (libcoro) arm assembly support, please test and report.
+        - adjust to PL_savestack changes in perl 5.24 (adapted from
+          the debian patch, which unfortunately gets it wrong).
+
+6.49 Sat Oct 17 01:40:12 CEST 2015
+	- throwing an exception to a thread waiting in
+          Coro::Handle using Coro::EV did not stop the watchers,
+          causing the next call to fail (testcase by Martin Pritchard).
+	- bump minimum perl version to 5.10.
+
+6.48 Sun Oct  4 19:03:51 CEST 2015
+	- fix memory leak when Coro::Handle uses Coro::EV internally
+          (testcase by Sten Sten).
+        - update code to libev 4 API (internally, Coro still used the
+          version 3 API calls).
+        - remove unused hv_sig.
+
+6.47 Sat Jul 11 03:58:20 CEST 2015
+	- swap_svs - NVs can be in the SV head beginning with 5.20.
+
+6.46 Tue Jun 30 14:36:30 CEST 2015
+	- restore portability to perls with windows fork emulation
+          (patch by Petr Písař).
+
+6.45 Tue Jun 30 01:40:08 CEST 2015
+	- restore portability to perl 5.16 and below.
+
+6.44 Tue Jun 30 00:41:54 CEST 2015
+	- avoid segfaulting (or worse) when tracing a canceled thread.
+	- the Event module silently broke it's public hook API, causing
+          failures on perls compiled with -Duselongdouble. Requiring
+          the latest version of Event because I don't know which release
+          changed this (it's not mentioned in the ChangeLog).
+        - allow xs level enterleave hooks via CoroAPI.
+
+6.43 Thu Jun  4 15:38:14 CEST 2015
+	- use stability canary.
+	- port to stableperl-5.22.0-1.001.
+        - update libecb.
+
+6.42 Wed Feb 11 20:29:52 CET 2015
 	- Coro::SemaphoreSet->try did not actually work (analyzed by
           SATO Kentaro).
+        - upgrade libecb to be C11 compliant.
 
 6.41 Sat Sep  6 22:08:46 CEST 2014
 	- restore portability to perl 5.8.x.
