Without having played very far into 2.01a, hard to say how dif it might be from 2.0, but generally seems like minor difs..
Pretty sure this isn't complete, but here's a ReadMe.txt file in v2.01a:
Upgraded to later zlib varsion
Sort Spell lists, by level from 7 down to 1, and by name from a to z.
The stronger spells are at the top, and the weaker ones are at the bottom.
<esc> in Automap closes
<esc> in <esc> menu closes
Equipping an item while in combat may have caused savegame problems.
Removed store buying cheat.
Fixed chest description overwrites options.
Uninitialized variable in using skills/spells may have caused some crashes.
Dynamic loading of Actions.Dat should provide missing skills.
Better spell usage for some spellcaster monsters.
The Action editor was incorrectly assigning Paralyze resistance
instead of no resistance for melee style attacks.
Paladins were able to make bosses surrender.
New Ogre pictures. Some of the old ones may have caused problems.
Maybe these are just the tweaks from ver 2.01 to 2.01a ?
The experience tables were changed from v2.0 to later, & new items introduced, for ex..
Origen, have you gone on vacation??
