+6.55  Fri Jul 19 17:28:09 CEST 2019
+	- Coro::RWLock woke up only one reader instead of all after a wrlock
+          (analyzed and patch by Maxim Skorobogatov).
+        - slightly improved documentation of Coro::RWLock and RWLock testcase.
+        - quickly (re)-ported to minix 3.3 before minix crashed again.
+
+6.54  Sun Dec 16 11:06:07 CET 2018
+	- reinstate Coro::Select::select prototype - it breaks more than it fixes.
+
+6.53  Sun Dec 16 10:33:15 CET 2018
+	- the autogenerated prototypes of Coro::AIO now add ";" at the end
+          to avoid generating named unary operators and messing up parsing
+          (mostly affects aio_mlockall 4 | 8 which was parsed as
+          (aio_mlockall 4) | 8).
+        - do not use a prototype for select in Coro::Select, as CORE::select also
+          doesn't have one.
+
+6.52  Tue Aug 14 18:49:43 CEST 2018
+	- libcoro update: allow sharing of coro threads using the pthreads
+          backend among different pthreads, as is required by Coro::Multicore.
+	- always allow ->call and ->eval when the coro is the current coroutine. this
+          makes it possible, among other things, to call these on $Coro::main.
+	- minor code cleanups.
+
+6.514 Thu Aug 31 18:25:31 CEST 2017
+	- 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.
+          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.
