+1.03
+====
+
+- a real networking support! (ported from TyrQuake project)
+
+- used standard XBIOS call for both VGA and RGB resolution setting
+
+- decreased memory usage to 32 MB (IMO, still much more than needed)
+
+- preliminary SuperVidel support (screen buffers are placed into SV memory
+  instead of the slow ST-RAM but the C2P process still takes a place)

   need a perl package from sparemint distribution to run it
 
 - it's possible you'll get some compile errors -- i use some own <mint/*> 
-  includes (with constants from Atari Compendium) -- drop me a line if 
-  you're interested
+  includes (with constants from Atari Compendium); newer mintlib versions
+  already contain these changes
 
 - asm68k directory contains original amiga sources. but beware! they had 
   to be changed since not everything can be handled by perl script!
