=============
-GHC 3.00 is a source-only release. There are no binaries available at
-the current time: in the interests of spending more time hacking and
-less time building distributions, we're shoving this one out as
-quickly as possible so that intrepid hackers can try it out.
+GHC 4.01 is a small increment over 4.00. Many bugs have been fixed.
+The following features are new:
-Important new features:
+ * Weak pointers,
+ * The foreign function interface is now complete.
- * Multi-parameter type classes. Please try 'em out; we'd
- appreciate the feedback.
+In addition, bootstrapping the compiler should now work out of the box.
+
+The following things have not been fixed yet:
+
+ * The native code generator is still flaky, and is turned off by
+ default for the time being.
+ * The profiler is still flaky.

======================
-To compile up this source-only release, you need a machine with 16+MB
-memory, GNU C (`gcc'), `perl' plus a version of GHC installed (either
-version 0.29 or 2.10 onwards). We have seen GHC work on these platforms:
+To compile up this source-only release, you need a machine with 32+MB
+memory, GNU C (`gcc'), `perl' plus a version of GHC installed (version
+2.10 at least). This release is known to work on the following platforms:
+
+ * i386-unknown-{linux,solaris2,freebsd,cygwin32}
+ * sparc-sun-{sunos4,solaris2}
+
+Ports to the following platforms should be relatively easy, but
+haven't been tested due to lack of time/hardware:
* alpha-dec-osf{2,3}
* hppa1.1-hp-hpux{9,10}
- * sparc-sun-{sunos4,solaris2}
* mips-sgi-irix{5,6}
- * i386-unknown-{linux,solaris2,freebsd,cygwin32}.
* {rs6000,powerpc}-ibm-aix
