Version number scheme

We're currently using a date.month.day.totalminutes version scheme. This scheme has some nice advantages:

  • See immediately how old an assembly is
  • Fully automatic
  • We don't want to care about versions
  • We work incrementally in small steps and usually don't break stuff (but use Obsolete to tell dev's about breaking changes)
  • We don't need the flexibility because we don't patch older versions anyway (just fixing builds in mainline, causing a new version)

Yet in the context of NuGet, the classical version format (major/minor/revision) does have some advantages as well:

  • Semantics: minor number changes are expected to be backwards compatible, revision number is essentially for specific bugfixes (without bringing in other changes)
  • NuGet, OpenWrap etc. actually are smart enough (and getting smarter) to use that semantic data e.g. when two dependencies both depend on a package but with different version
  • We would get more flexibility (e.g. for bug fixing and old version) in case we'd actually need it at some point in the future
  • Being more "standard"

I'm fine with both approaches, yet we might get into trouble when we want to change the approach later and try to make NuGet recognize "MathNet.Numerics-2.0" as newer than "MathNet.Numerics-2011.01.02.213"

What do you think?

Thanks,

I'm partial to date based versions, but have no problem using the more standard version if it makes setting up NuGet easier.

So am I. Date based also has the additional advantage that we don't have to change anything ;)

I'll try to continue with date-based versions.

Thanks,
