Because of really huge amount of modifications here I've probably missed some minor stuff. I doubt if it's still compatible with gcc - some changes should be reapplied.
* correctly showing recruitment window (recruitment not ready)
* new slider class
* creature growths handled (horde buildings not yet supported)
* buttons more secure
* info about factions and their creatures
* costs of creatures merged into vector
* info about town structeres state (started)
* new function in CSDL_Ext for drawing borders
* numerous minor changes
* load time significantly decreased also (now it's almost like in OH3)
* TODO: make extensively used CSDL_Ext::blit8bppAlphaTo24bpp faster - it slows down VCMI too significantly, but I'm sure it can be as fast as the code from SDL and anyway those speed-ups and memory usage decrease were worth it ;]
* CDefEssential is now useful
* initGameState shouldn't overwrite starting armies
* loading more graphics (small creature icons, large hero portraits)
* functions for getting current valueof morale/luck (unfinished)
* added in CLodHandler function that returns CDefEssential with images from desired .def
* copySurface works correctly (I hope)
* functions for getting info about heroes in CCallback
* function for initializing GameState
* improvements in CHeroInstance
* added codename
* minor stuff
* names of lods changed - rename your lod files to h3sprite.lod and h3bitmap.lod and place them in \Data subfolder (as in H3).
* added several clickable buttons to adv. map interface
* underground/surface switch button is functional
* reading more text from ZELP.txt, added CPreGameTextHandler to CGameInfo
* a lot of minor improvements/fixes(/bugs)
* more player interface (but it's still beginning)
* int3 members public
* more usage of int3
* adjusted animation speed
* reversed changes from rev.165 in CPreGame - it wasn't bug, it just works so. That change was breaking a few things in CPreGame and was needless - Player ID == Player's Color. I thought it was obvious.
* minor stuff
* Fixed several memory leaks
* Added support for player colors in CMessage (still need some work)
* Moved declarations of CPreGame buttons to CPreGame.h
* started making player interface (new button classes etc)
* now you can choose castle in scenario options
* function blitAtWR works as blitAt, and refreshes destination rect
* vectorize function (on TowDragon's wish) - may be useful for debugging
* as always- minor bigfixes
* CLodHandler init cleared up (a bit)
* giveDef optimized
* horizontal slider
* printAtMiddle updates corrrect rect
* adjusted shadows
* parts of advanced options menu
* minor fixes/improvements
