Version maintenance / End of Life (EOL) policy

For reference, we use this software version number structure: <major>.<minor>.<build>

Maintenance period

A version (<major>.<minor>) of Simple DNS Plus is maintained for (which ever comes last):

  • 3 years from the initial release date (general availability)
  • 2 years from the End of Sale date (new version is released)

Maintenance level

  • Full
    Only the most recent version (<major>.<minor>) receives full maintenance. That is we try to fix bugs as quickly as possible and make minor adjustments as needed.

  • Limited
    When a new version (<major>.<minor>) is released, the previous version enters a limited maintenance phase during which we issue bug-fixes for critical security issues, but otherwise consider bug-fixes / adjustments on a case by case basis. We may instead direct users to workarounds when possible.

Version numbers

As of November 2017 we increment version numbers as follows:

  • <major> is incremented when there is one or more new major features, a bunch of new minor features, or when we significantly restructure the software.
  • <minor> is incremented when there is one or a few new minor features, or when we make minor structural changes.
  • <build> is incremented for bug fixes / minor adjustments to existing features.
