-Release 3.8.0 (????)
-~~~~~~~~~~~~~~~~~~~~
-xxx Don't forget to update VALGRIND_MAJOR/MINOR before release
+Release 3.8.0 (XX August 2012)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+3.8.0 is a feature release with many significant improvements and the
+usual collection of bug fixes.
+
+This release supports X86/Linux, AMD64/Linux, ARM/Linux, PPC32/Linux,
+PPC64/Linux, S390X/Linux, MIPS/Linux, ARM/Android, X86/Android,
+X86/MacOSX 10.6/10.7 and AMD64/MacOSX 10.6/10.7. Support for recent
+distros and toolchain components (glibc 2.16, gcc 4.7) has been added.
+There is initial support for MacOSX 10.8, but it is not usable for
+serious work at present.
* ================== PLATFORM CHANGES =================
+* Support for MIPS32 platforms running Linux. Valgrind has been
+ tested on MIPS32 and MIPS32r2 platforms running different Debian
+ Squeeze and MeeGo distributions. Both little-endian and big-endian
+ cores are supported. Memcheck, Massif, Lackey, Callgrind and none
+ are tools that have been tested and are known to work well. See
+ README.mips for more details.
+
+* Support for Intel AVX instructions and for AES instructions. This
+ support is available only for 64 bit code.
+
+* Preliminary support for x86 platform running Android.
+
+-------------
+
* Support for intel AES instructions (AESKEYGENASSIST, AESENC, AESENCLAST,
AESDEC, AESDECLAST, AESIMC). Only supported for 64 bit architecture.
* Support for Intel AVX instructions.
-* Support for MIPS32 platforms running Linux. Valgrind has been tested on
