+
+Release notes for version 4.06—1/00
+
+
+
+
+
+
+
+
+User visible changes
+
+
+
+
+
+Major library reorganisation. The libraries are now split into 8
+categories:
+
+
+
+
+concurrent
+
+
+Same as the old concurrent library
+
+
+
+
+
+data
+
+
+Datatypes. Contains old FiniteMap
+and Set modules, and Chris Okasaki's Edison
+library.
+
+
+
+
+
+lang
+
+
+contains most of the contents of
+the old exts library
+
+
+
+
+
+net
+
+
+networking-related libraries (Socket, SocketPrim, and
+new URI library).
+
+
+
+
+
+num
+
+
+numerical-related libraries (currently empty).
+
+
+
+
+
+posix
+
+
+the old POSIX library
+
+
+
+
+
+text
+
+
+text-processing related libraries (including Andy Gill's
+HTML library)
+
+
+
+
+
+util
+
+
+various miscellaneous libraries, including John Hughes'
+and Koen Claessen's QuickCheck library.
+
+
+
+
+
+
+See the accompanying libraries documentation for more details.
+
+
+
+
+
+Cleanup of concurrent I/O system. We now use non-blocking I/O on
+all Handles, so that multiple threads can do I/O simultaneously.
+We don't however do non-blocking I/O on stdout/stderr,
+due to reports that some shells don't correctly restore
+blocking mode on these file descriptors after running a program.
+
+
+
+
+
+Exception changes
+
+
+
+
+raiseInThread can now raise exceptions in threads blocked on I/O or time delays.
+
+
+
+
+
+New functions in Exception
+
+
+blockAsyncExceptions :: IO a -> IO a
+unblockAsyncExceptions :: IO a -> IO a
+
+
+used to control the delivery of asynchronous exceptions to
+a thread (including those raised via raiseInThread).
+
+
+
+
+
+Asynchronous exceptions are now blocked by default inside
+an exception handler. Use unblockAsyncExceptions to
+restore the previous behaviour.
+
+
+
+
+
+
+
+
+
+
+Add NetBSD/x86 support.
+
+
+
+
+
+Added support for foreign export dynamic.
+
+
+
+
+
+
+
+
+
+
+Minor changes
+
+
+
+
+
+Build system cleanup—BIN_DIST=1 is now needed in build.mk (before building!) to build binary dists.
+
+
+
+
+
+New RTS option , which prints the current cost-centre
+stack to stderr whenever an exception is raised (only for
+profiling builds).
+
+
+
+
+
+
+
+
+
+
+Not-quite-ready-yet, but in there nontheless
+
+
+
+
+
+SMP support
+
+
+
+Building way 's' on a system with pthreads (only tested on
+Linux so far) will include support for running multiple
+Haskell threads on several pthreads simultaneously. If
+your system supports it, this will enable Haskell programs
+to take advantage of multiprocessor SMP machines.
+
+
+
+
+
+
+GranSim and GUM
+
+
+
+Initial ports of GranSim and GUM to GHC 4 are in there. Not quite
+ready yet.
+
+
+
+
+
+
+Profiling
+
+
+
+Heap profiling sort-of works. Only cost-centre heap
+profiles are supported so far.
