New release, i dont remember what did i do, but the changelog says lots of stuff:
Didnt make the script object editor yet

COMING SOON (means months)
------------------------------------
0.5.27 Beta (09.04.2010)
------------------------------------
- Added map screenshot maker; can take fullsize map screenshots by using current camera altitude. (File -> save -> Map image). Note: taking bigger images can take up to 800 megs memory. preferred tile sizes: 8 to 32. (means 12 to 200 megs memory usage).
- Sprite animations are now synced with time (no longer spins too fast!).
- Added framerate limiter. (options -> rendering settings -> framerate limiter). Use this if V-Sync isnt supported on your GFX card. Unfortunately i couldnt make the FPS limit exactly 30 or 60, you have to use 32 or 64 (or some other absurd values in the list).
- Added new rendering mode: Stereogram mode, cross your eyes to make the screen look 3d like it was real! Headache is the only thing that makes you want to stop using this feature! (options -> rendering settings -> render mode). Tips: 1: Disable menu (F1). 2: Use square window size (easier to focus). 3: Look at the screen from a good distance (about 50cm). 4: Cover some part of your left/right sight areas to get rid off the duplicate images in your vision, the closer at your eyes you cover it, the better.
- Will not load both platforms scripts anymore (PSX and PC). Added option in menu to switch between PSX or PC platform. (options -> GTA2 -> platform). This means you will no longer see PSX objects in the map if you have selected PC platform (default) and vice versa.
- Improved free camera mode to be faster in rendering when looking only a small part of the map. This also fixes the bug that appeared when perspective angle was adjusted (didnt render everything you could see). Note that going outside of the map, or looking up will cause it to render the whole map = slower (although this was how earlier version worked too). It still has some flaws: it doesnt always work perfectly when perspective is changed or if camera is using certain angles.
- Added options to resize the script objects by their object type (or all at once), use this with the fullsize map screenshot maker. (options -> script objects -> scale). Also added default layout to quickly change only the generator object types sizes to 2.5x bigger, and everything else normal size.
- Added option to change tiles and script objects texture quality (options -> rendering settings -> texture settings -> texture filter). use pixelized tile textures mode with the fullsize map screenshot maker to get better quality images. If you have low FPS, you may also get some more FPS with pixelized textures mode.
- Infinite water texture uses the map most used water tiles now (that one which has animation set to it). Also if there is no water lid tiles in the map, it will set infinite water texture to the most used lid tile of the map.
- Fixed screenshot saving on certain window sizes.
- Added option to change the image formats for screenshots, minimaps and map images. Possibilities are now: TGA, BMP and JPG. Also JPG quality can be changed. (options -> settings -> saved images formats).
- Added button to reload script file on runtime (F7).
- Fixed maplist: didnt list all maps, now it checks unique map names, instead of unique sty+bil combinations.
- Added keys to scroll maplist without mousewheel: pageup/pagedown now does the same.
- Added option to open the .mis file to chosen program from the editor. (file -> edit script file).
- Added option to always display weapon pick-up objects with 90 degree angle (looks better on screenshots). Default on.
- Added setting to disable sprites loading. (options -> loading settings).
- Added full support for COLLECT_(00-44), also support for MOVING_COLLECT_xx codes.
- Fixed ALPHA car and ANIMATING_OIL object to be visible. Also fixed/added support for several objects, including car skid marks (no remaps supported).
- Added blinking light for POWERGEN object. Also POWERGEN_DEAD object support added.
- CAR_SHOP objects have sprites now: using the weapon icons, and "S" letter for spray shop. Can also be disabled separately. (options -> script objects -> carshops).
- Added support for CHAR_DATA. They will be displayed with default ped walking animation, still no remaps supported yet. (options -> script objects -> chars). (default off).
- Added SOUND objects visible, they will be always placed at the highest position from top, unless there is no ground under them where they can collide. (options -> script objects -> Sound objects). (default off).
- Added option to disable sprite animations (options -> script objects -> animations).
- Added option to disable shadows for script objects. (options -> script objects -> shadows).
- Map checksum calculation fixed: checksum wont change when editing zones and other stuff that has no effect on the minimap appearance. This way it becomes slightly faster to calculate too.
- Added rendering setting "face culling" (default enabled), it improves rendering speed on some cases, for example when wireframe (G) mode is enabled.
- Added option to make textures sharper/smoother from the menu. (options -> rendering settings -> texture settings -> texture sharpness). sharper textures = slower.
- Added button to zoom in/out without mousewheel: (CTRL+ or SHIFT+) HOME/END. shift = slow, ctrl = fast.
- Added fog settings in the menu. (options -> rendering settings -> fog).
- Fixed triangle counter (showed more triangles than what there actually was).
- Fixed blend mode, when using ghosted flats, the blending mode was used everywhere else too.
- Added new render mode: heightmap mode. (options -> rendering settings -> heightmap).
- Added new texture mode: white textures (used with heightmap mode).
- Switching to top-down view will now reset the free camera mode flying speed.
- Added new render mode: sprite wireframe mode, makes it easier to see sprites locations (when map rendering is off).
- Added option to change infinite water radius. (options -> rendering settings -> water settings -> infinite water -> radius).
- Added option to disable flats rendering. (options -> rendering settings).
- Quick open map list will show maps that have modified style file with + mark at the beginning of the map name.
- Added links for Readme.txt and Changelog.txt in the Help menu, will open them in default edit program.
- Global map grids are not on by default anymore.
- Added "possible crashes" info in the Readme.txt
