Patch "m" is linked in the first post. It will break save games and could possibly cause herpes. It includes the following fixes:
1. Added 10 new events.
2. Bronze Working, Construction, Horseback Riding, Sailing, Archery, Warfare, Code of Laws, Writing, Knowledge of the Ether and Philosophy are all Classical Era techs instead of Ancient Era techs (so they won't be automatically given by Classical starts).
3. Fixed a CtD with the March of the Trees spell.
4. Sphener and Yvain regain the ability to cast Cure Disease and Heal.
5. Removed the Tracking tech (hunting cost increased slightly, Animal Handing and Poisons tech cost increased).
6. Archery can be researched through Hunting or through Mining.
7. River trade moved form Sailing to Fishing.
8. Scrubs will now be cleared with Vitalizing a desert to Plains.
9. Added a game option that places all the Unique Features on the map.
10. Fixed an issue where improvements around cities were deleted.
11. Fixed an issue that kept forts from upgrading if they were inside your borders but not being worked.
12. The Cult- the mountain block will be removed when the player completes the dungeon portion.
13. The Splintered Court- added the Parith event.
14. The Black Tower- Falamar no longer starts with Bronze Working, Construction, Horseback Riding, Archery, Warfare, Code of Laws, Writing, Knowledge of the Ether and Philosophy.
15. The Black Tower- reworked the starting island, shrunk it a bit, added some rivers.
16. The Black Tower- the AI gets bonus units depending on the difficulty.
