-  This is a minor bugfix release.
-  The primary reason for this release is to correct numerous build errors that have accumulated for the ZiLOG ZDS-II based targets.
-  All ZDS-II targets now build correctly (but have not been re-tested).
-  In addition to platform-specific build failures,  release also adds the following features which were not tested as of the time of the release:

-	* Added board support fot the ZiLog ez80Acclaim! ez80f910200zco Development Kit.
-	* Fixed several compilation errors in fixed precision math library when built
-	  against toolchains that do not support 64-bit type 'long long'.
-	* Fix errors in some function prototypes in dirent.h
-	* Add eZ80F91 EMAC driver
-	* Fix recvfrom() compilation error -- only noted under ZDS
-	* Updated all ARM Make.def files to work with gcc 2.4.2 (However, there are
-	  still some build issues associated with that toolchain in use of arm-elf-objcopy
-	  -- see the TODO.txt list for details)
-	* Fix problems with Z16F and eZ80 compilation introduced with recent changes.

+^^^^^^^^^^^

+This is the 34th release of NuttX.  This release adds no new OS features but does include
+support for two new architectures:
+
+	* ez80Acclaim!  Basic support has been integrated and verified for the ez80f910200zcog-d
+	  board (eZ80F91-based).  That basic support includes timer interrupts and serial
+	  console.  Ongoing work includes an EMAC driver that should be integrated for

+	  eZ80Acclaim! support has been in the code base for some time, but has only just
+	  been integrated due to toolchain issues.
+
+	* Renesas M16C/20.  Support for the Renesas SKP16C20 board has been included in
+	  the NuttX source tree.  However, as the the eZ80Acclaim!, testing and integration
+	  of that port is stalled due to toolchain issues.
+
+These changes were verified only on the ZiLOG eZ80910200zcog-d board. Please report any errors
