(svn r18634) -Revert (r16808): the fix doesn't work in all cases
-Fix [FS#3421] (r16838): crash when invalid pointers are left due to saveload failing at e.g. decompressing the savegame

(svn r18481) -Codechange: unify the curve pathfinder penalty defaults; 0.01 tile won't make a dent, 3 tiles might be a bit too much
-Feature-ish: make maximum pathfinder penalties for finding depots customisable, also increase it slightly to 20 tiles worth of penalties.

(svn r18404) -Codechange: link drive through stops better together
-Feature: make penalty for road stop occupancy user configurable
-Fix [FS#1944]: road vehicles would not pick an empty drive through stop. Now they will *if* the penalty for driving around is less than the occupancy penalty
-Fix [FS#1495]: long (articulated) road vehicles could block loading of others when the following road vehicle already got 'permission' to go to the next bay even when it could not reach it
-Change: improve the throughput of the drive through road stops by letting them stop closer together

(svn r17928) -Codechange: ShowErrorMessage() now takes the summary string before the details string.
Gentlemen, swap your string parameters.

(svn r17433) -Codechange: Store cumulated inflation in savegame and compute all prices from that instead of storing all prices separately.
Note: Savegame conversion computes the inflation from max loan. Prices from modified savegames will get lost. TTO savegames will also behave slightly different.
-Change: NewGRF price modifiers now take effect everytime when loading NewGRFs instead of once on gamestart.

(svn r17113) -Change [FS#265][FS#2094][FS#2589]: apply the subsidy when subsidy's destination is in station's catchment area and cargo packets originate from subsidy's source
-Change [FS#1134]: subsidies aren't bound to stations after awarding anymore, they still apply to town or industry, no matter what station is used for loading and unloading. Awarded subsidies from older savegames are lost
-Change [NoAI]: due to these changes, AISubsidy::GetSource and AISubsidy::GetDestination now return STATION_INVALID for awarded subsidies

(svn r16909) -Fix [FS#2996]: NewGRF stations would be triggering assertions all over the place when using the more advanced station types.
-Change: make (rail) waypoints sub classes of 'base stations', make buoys waypoints and unify code between them where possible.

(svn r16694) -Fix [FS#2995] (rgradual loading, rnewindustries): only pay for whatever has been actually unloaded and perform the payment when unloading has finished. This fixes, amongst others:
* cheating by starting to unload and after getting paid rushing to the depot to get sold (or unloading, loading and getting paid again for the remainder)
* cargo being dropped onto a station at the moment a stockpiling industry doesn't accept it anymore
* industries getting cargo that has not been unloaded yet and subsequently dumping it back on the station in one go
Note: you will now get paid after the unloading has finished, so you'll have to wait a bit longer for 'your' money.

(svn r16338) -Codechange: split loading of references to two phases
In the first phase, indexes are stored. In the second phase, indexes are checked for validity and converted to pointers

(svn r16269) -Codechange: use gcc's ability to check parameters sent to printf-like functions
-Fix: wrong number of parameters or wrong parameter types sent to printf-like functions at several places

(svn r16242) -Codechange: rework pausing
-Fix [FS#2864]: autopause and manual pausing conflict with eachother
-Fix: new game + pause on new game + autopause make the game not unpause on the first join

(svn r15695) -Feature [FS#2672]: Allow the number of towns that will be generated in the generate world window to be customized.
Some warnings:
-the maximum number of towns to be accepted is set to 5000
-the minimum number of towns to be accepted is set to 1
-the number that is specified is NOT guaranteed to be the exact number of towns generated. The normal mechanism of town creation has not been modified. So town placement can still fail.
-setting a custom number of town will change your difficulty settings to custom as well

(svn r15601) -Fix [FS#2615]: bridges/tunnels don't store tram owner making it possible to remove someone's tram tracks.
-Feature: allow building road stops on road/tram tracks of competitors.

(svn r15340) -Fix [FS#2121]: changing town road layout in-game caused ugly road networks
-Fix: use a flag instead of TL_NO_ROADS to forbid towns to build roads. The flag is ignored during world generation, so there won't be 'ghost' towns anymore
-Feature: town layout is now stored per town, so it is possible to (manually) set different layout for each town

(svn r15287) -Cleanup: some code style, remove erroneous comment.
-Document: the fact that zlib reads uninitialised data (valgrind notices this) and that it won't be fixed in zlib and that we can't do anything about it except ignoring it.

(svn r15045) -Add [NoAI API CHANGE]: in info.nut you can now have (optional) a CanLoadFromVersion(version), which should return true/false, to indicate if you can load a savegame made with your AI of version 'version'
-Add [NoAI API CHANGE]: in main.nut the Load() function now should be Load(version, data), where 'version' is the version of your AI which made the savegame
-Codechange [NoAI]: various of function renames to make things more sane
-Add [NoAI]: push the 'version' of the AI through various of layers
-Codechange [NoAI]: various of code cleanups
-Add [NoAI]: store the version of the AI in the savegame too

(svn r15027) -Merge: tomatos and bananas left to be, here is NoAI for all to see.
NoAI is an API (a framework) to build your own AIs in. See:
