-  Pth 1.4 has an even more extensive support for auto-configuring
-  the package to work on the different Unix platforms without the
-  requirement for the end user to manually adjust the package.
-  Additionally the underlying thread creation and dispatching mechanism
-  was greatly enhanced and cleaned up, too. With this, version 1.4 now
-  was successfully built and tested on numerous Unix platforms, ranging
-  from the major ones like GNU/Linux, FreeBSD, NetBSD, OpenBSD, BSDI,
-  Solaris, HPUX, Tru64, AIX, IRIX, UnixWare and SCO, to more esoteric
-  flavors like SINIX, ReliantUNIX, ISC, SCO, NCR, AmigaOS, Rhapsody
-  (MacOS X), FTX, AUX and Win32/Cygwin.

-  Additionally the auto-configuration mechanism allows GNU Pth to
-  automatically adjusts itself to run also on mostly all remaining Unix
-  platforms, including ancient versions for which a multi-threading
-  environment never existed before. This is especially achieved in Pth
-  by not using any assembly code or platform specific solutions and by
-  using a very tricky but portable thread creation fallback approach
-  which will be published in great detail on the USENIX 2000 Annual
-  Conference this summer.
+  NEW IN PTH 2.0
+
+  Pth 2.0 provides more strict POSIX.1-2001/SUSv3 compliant wrapper
+  functions in its high-level I/O API. Most notable, the implementations
+  of pth_poll(3) and pth_select(3) were completely worked off in order
+  to achieve POSIX semantics. A Pth variant of the new POSIX pselect(2)
+  function was introduced, too.
+
+  Pth now has support for arbitrary (usually higher than the default)
+  FD_SETSIZE values to support larger-scale server applications.
+
+  A new environment attribute PTH_ATTR_DISPATCHES allows the application
+  to query the total number of machine context dispatches Pth performed
+  since the last attribute reset.
+
+  Pth's internal machine context implementation is now exported in a
+  sub-API pth_uctx in order to allow applications to use raw user-space
+  context switching. This can be used to implement co-routines,
+  exception handling or even an alternative multi-threading environment
+  with the help of Pth.
+
+  The "hard syscall mapping" functionality was completely rewritten
+  from scratch. Previously, the internal system call exit points were
+  based on syscall(2) only. This was problematic because it by-passed
+  the C library glue code which often performs necessary glue code in
+  order to call the code in the kernel correctly. Now the internal exit
+  points are based on a by-system-call dynamically selected combination
+  of RTLD_NEXT+dlsym(2), dlopen(2)+dlsym(2) and the known syscall(2) (in
+  this fallback order). This way the "hard syscall mapping" became a lot
+  more portable and flexible.
+
+  Optional support for OSSP ex based exception handling was added which
+  allows ISO C applications to use fully multi-threading aware ISO C++
+  style exception handling.
+
+  Finally, the Pth build environment was upgraded to be now based on GNU
+  autoconf 2.57, GNU shtool 1.6.2 and GNU libtool 1.4.3.
