Calendar based versioning

Our goal is to release new versions of DBmarlin each month so that customers get a constant stream of new features on a regular basis.

Typically, the new version will be available towards the end of the month, but could be earlier or later depending on the development and testing cycle.

The versions are numbered, based on the year and month they were released (or were intended to be released in the case where a release may be delayed by a few days).

The version will be in the form of 3 numbers separated by dots.

  1. The first number = Major version → Last digit of the year it was released. E.g. 3 for the year 2023
  2. The second number = Minor version → The number of the month it was released. E.g. 2 for February or 11 for November.
  3. The third number = Patch version → Usually 0 if there is only one release in the month but could be 1, 2, 3 etc if there are additional patches or updates released within a month.

Some examples:

  • 3.3.0 is the 2023 March release.
  • 2.11.0 is the 2022 November release.
  • 2.11.1 is the first patch to the 2022 November release.

Supported versions

We will always support any version released within 12 months of the current date.

For example, at the time of writing, 4.2.1 (released March 2024) is the current version, so we would support all versions back to 3.2.0 (released March 2023).

Upgrading to a supported version

We always attempt to maintain backwards compatibility with our upgrade process. However, should you need to upgrade by several Major versions, we strongly suggest that you go one Major version at a time. For example to get from 1.10.0 to 3.3.0, you should move from 1.10.0 to 2.12.0 and then from 2.12.0 to 3.3.0. As usual, always take a backup before you start just in case of any problems.
