The new way to version software
The Complete Drone-Ver Specification
This also lives at drone-ver.org.
Given a version number MAJOR.MOOD.ISSUES.SOCIAL.DICTIONARY.UNIXTIME.SEVEN, manage your releases as laid out in this comic:
- MAJOR is incremented when you feel like you've added something cool.
- MOOD is how you felt when you released this version.
- ISSUES is the number of open GitHub issues against your project.
- SOCIAL is the number of GitHub forks & favourites of your project.
- DICTIONARY is a random dictionary word.
- UNIXTIME is the unix time, and
- SEVEN is always the number seven (7).

This is clearly a satirical response to Semantic Versioning as there are some
who don't like it.
I found the Drone-Ver stuff hilarious (why yes, I am a geek—why do you ask?) and according to it,
mod_blog should be at version
(assuming bug fixes are “something cool”)
instead of the current version of
But I also found Semantic Versioning to be a decent attempt to make version numbers have some semantic meaning. Semantic Versioning seems to be geared more towards libraries, and if there was one change I would make to it, it would be that minor versions (backward compatible changes or enhancements) shouldn't break user code (so that if you have a program that uses Foo major version 4.0.n, it should compile cleanly against 4.1.n, 4.2.n, etc. since they all should be compatible) but that bug fixes might break user code (if, for instance, you worked around it, or somehow used the bug as a feature of your code) but if you used the API as described, things should be okay.
Semantic Versioning breaks down for applications though, as there is no real API to speak of (which causes a change in the major version number). I think a good approach for applications with Semantic Versioning is that a major version should only change if configuration or data files change format (such that the new format is incompatible with the older format, or the older version can't load newer versions of the configuration or data files), new features or enhancements cause the minor version number to update, and bug fixes bump the patch version.
Using that criteria,
mod_blog would be at version
2.7.5—there was a configuration file format change when I switched from using my own half-baked configuration format to using
Lua as the configuration format
the storage format for
mod_blog hasn't changed one bit in fifteen years,
although it has been enhanced,
older versions would be able to deal with the newer information by simply ignoring it).
And just for the record:

The history prior to version
2.0 is … um … murky.
I had … issues … with the previous version control system
so pretty much the history from December 1999 through May 2009 have
been lost in time,
like tears in rain.
As you can see,
the version numbers have been inconsistent early on,
but as time went on,
I've done a bit better with the version numbers
(it's been more consistent with
