softwareBy convention, would a software version 0.9.101 come before or after version 0.9.90? And why?
Short answer:
Version 0.9.101 is usually released after 0.9.90. But it depends on you what kind of version numbering scheme you use.
Long answer:
From my experience, a common version numbering scheme is something along the lines of
major.minor[.bugfix]
where each of these numbers can be increased as far as needed. Also, when sorting the version numbers each part is interpreted as a number, so, as 101 is bigger than 90, version 0.9.101 is considered newer than version 0.9.90.
If you, for example, add a minor new feature to version 0.9.101, you can release it as version 0.10[.0], and because 10 is bigger than 9, version 0.10 will be perceived as newer than version 0.9.101.
As a real world example, have a look at the past releases of Mac OS X. In 2013, Apple released OS X Mavericks (version number 10.9) and in 2014 OS X Yosemite (version number 10.10). Other releases now were numbered e.g. as 10.10.4. Although for these numbers, the major part is actually the second part. The first 10 comes from the X in Mac OS X (a roman 10). So currently Apple uses something like 10.major[.minor] for the OS X releases.
