(Title is slightly misleading, any number with 3 or more digits is not incremented. Sorry)
I used to use version numbers that were split, such as v5.11, where the first number notates major changes or releases, and the number behind the dot notates minor changes. To take advantage of the automatic incrementing I recently changed that system by simply excluding the dot, so the version number above would now be v511.
Sadly the updater can only increment up to 99. Anything with three digits or more remains unchanged. That includes v001 for example, or v1000.
