There's no such thing as a change log I guess. Changes:
C:\Program Files (x86)\Steam\steamapps\common\sid meier's civilization iv beyond the sword\Assets\Python\PitBoss\PbWizard.py - minor editing to remove the Direct IP option from the pitboss client menu.
C:\Program Files (x86)\Steam\steamapps\common\sid meier's civilization iv beyond the sword\Assets\Python\Screens\CvOptionsScreen.py - commented out code (dropdown boxes) related to selecting audio capture and playback devices
C:\Program Files (x86)\Steam\steamapps\common\sid meier's civilization iv beyond the sword\Assets\XML\Text\CIV4GameText_Civilopedia_Bonuses.xml - fixed a typo (missed the word "be" in the English Civilopedia description of the Banana resource!
)
C:\Program Files (x86)\Steam\steamapps\common\sid meier's civilization iv beyond the sword\Assets\XML\Text\CIV4GameText_Civilopedia_CivLeaders.xml - fixed typos in the English Civilopedia entries for Greece and Japan
C:\Program Files (x86)\Steam\steamapps\common\sid meier's civilization iv beyond the sword\Assets\XML\Text\CIV4GameText_Misc1.xml - added a new popup box saying "Steam Account Needed - Please launch and log into Steam in order to access multiplayer."
Consolidated a few Assets(0-3).fpk files into a larger Art0.FPK file
C:\Program Files (x86)\Steam\steamapps\common\sid meier's civilization iv beyond the sword\assets\CvGameCoreDLL.dll - file is smaller now, probably redid a lot of the network code but I don't know how to open up .DLL files to check them out. The text part of the file is different now, though, but just showing the different file size now.
Removed various .ico (icon) files
C:\Program Files (x86)\Steam\steamapps\common\sid meier's civilization iv beyond the sword\Beyond the Sword\Resource\Themes\Civ4\Civ4Theme_Common.thm - Changed some text fonts and colors. Why? Just so we'd know something is different?
C:\Program Files (x86)\Steam\steamapps\common\sid meier's civilization iv beyond the sword\Beyond the Sword\config\config.vdf - added this file, seems to have to do with network testing for finding closer servers to connect to.
C:\Program Files (x86)\Steam\steamapps\common\sid meier's civilization iv beyond the sword\Beyond the Sword\logs - 3 new files here, logging the new networking system.
C:\Program Files (x86)\Steam\steamapps\common\sid meier's civilization iv beyond the sword\CvGameCoreDLL (directory -- has been removed! Yeah, the DLL source is no longer included....)
C:\Program Files (x86)\Steam\steamapps\common\sid meier's civilization iv beyond the sword\testapp2.exe - removed
C:\Program Files (x86)\Steam\steamapps\common\sid meier's civilization iv beyond the sword\testapp8800.exe - removed
Several of the built-in mods have changes, mostly to their own game DLLs.
Other miscellaneous DLLs have been removed, some new ones added.
This list isn't exhaustive. I had about 900 asset files I couldn't restore quickly from Previous Versions due to the length of the file path/name . I can restore them from online backup but it's getting kind of late for that tonight.
