Is the versioning scheme only in .001 increments? I know version numbers aren't indicative of progress, but I still find it fascinating that a 26 year old project is just releasing 0.260
ah yes they skipped because there were a ton of releases from .38 to .52 that where basically .39 v6 (fixes something). So they figured out how many then added it.
Yep. In fact, the first releases of MAME had 0.01 increments. Not sure when they went to finer steps, but it is pretty much a given that they'll do it again when the current revision gets too close to 1.
MAME just has a permanent "0" major version, and the minor version continues to be bumped up forever. It's not a decimal number, so "close to 1" doesn't really make any sense.
