SVN should update every file..
It only updates the files which have been changed...
Im no C++ OpenGL programmer, so I don't look closely to the C++ code, just the BlitzMax examples...
I check the updates page, and if there is an update, I run the update.bat file, then rebuild and test the samples...
Also, r57 shows a load of other changes to the shaders.
Sorry, but why didn't you check before... I'm just uploading the dll for people who are having trouble compiling it....
