Version numbers
###############

To understand how Novius OS versions are numbered, let's take a closer look at this sample release: Dubrovka 4.1.2

* The first part (“Dubrovka 4”) is the major version. Novius OS major versions are numbered and also named after a city to be easier to identify (in alphabetical order, e.g. 'D' is the 4th letter of the alphabet). Major versions bring new features—for both end users and developers—, bug fixes and breaking changes often occur.
* The second part (“1”) is the in-between version. In-between versions mainly bring bug fixes and small improvements, although new minor features might be available too. Breaking changes don't occur.
* The last part (“2”) is the minor version. Minor versions are security or bug-fixing releases only. They don't bring new features and are therefore transparent to the end user. Updating is straightforward.

.. note::
  Prior to Novius OS Dubrovka, version numbers didn't fully follow the pattern described above.
