+	* New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed 
+	    by Edward Betts <edward@debian.org>
 	* Fixed a bug in both cp and mv preventing 'cp foo/README bar'
 	    type commands (file in a directory to another directory) 
 	    from working.

 	* Added -o loop option for mount, and support in umount for loop
 	  devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
 	  <bcollins@debian.org>
+	* Several fixes from Marco Pantaleoni <panta@prosa.it>
+	    * compile in fullWrite() not only if BB_TAR is defined, but also
+		if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
+	    * add some compiler optimizations to further reduce executable size
+		(as a side note, on my machines the largest code is generated by
+		gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with -O2
+		-m386 ...)
+	    * Compile no longer fails if busybox.def.h defines BB_FEATURE_LINUXRC 
+		but not BB_INIT.  (init_main used to be referenced, but not compiled)
+	* Fixed a bug in setting TERM for serial console support.  TERM now
+	    defaults to "ansi" for serial consoles.
+	* Fixed a bug in handling the CONSOLE env. variable for serial consoles.
