Version 2.1 of the Players Handbook has been updated to include the following:

• Minor tweaks and balances to bring this in-line with the version 2 of the Referee and Monster books
• Minor amendments/balancing of class abilities (these are now 'passive' or 'encounter' based to mirror Monsters)
• Equipment cost amendments
• Crafting & Alchemy section revised
• Additional Elven & Dwarven Gods added
• Renamed Spy class to Assassin class
• Updated artwork

Please note that I have also uploaded a zine (A5) sized version of the rules as a download option. This is simply a re-sized version of the 'letter' sized version (and has been slightly stretched to fit the A5 format) and does not contain embedded .pdf links within the document.
