I know that there are no fixed rules about software version control but I have several questions.
1) How to upgrade versions correctly
I have a small software that I started a while ago and since i started from scratch I started with version 0.1.
As I added more functionality I have been upgrading the minor number. Now I'm in v0.5.7 (minor (.5) for new functions and revision (.7) for bug fixes and minor changes), the thing is that the program is almost complete for distribution, but now I'm "missing" several minor versions, how do you guys handle that situation? do you simply just jump the numbers?
That brings me to the second question.
2) Which is a good starting version number
I am about to start a new project. This time is not that small of a project and is going to be public and free for modifying, I do not want to have the issues mentioned above. So which would be a good starting point?
Bonus question:
3) Is it ok to make numbers above 10? like v1.25 or v2.2.30?
I haven't seen software with that kind of numbering (probably they show it only in the help section or in their web-page), again I am aware that there are no rules for that but it seems to be that there is a general consent on how to keep the version numbers.
