MariaDB Release Model

You are viewing an old version of this article. View the current version here.

Current MariaDB Release Model (from 10.7 up)

  • There is a new innovation release four times a year. It is an RC release.
  • An innovation release is maintained for one year after the first GA release
  • Every eighth innovation release an a long-term support (LTS) release, which is maintained for five years after the first GA release
  • An LTS release concludes a major release series, the next innovation release will have a new major version number
  • Between two innovation releases there is a preview release, it is feature-complete, but has alpha maturity, it's purpose is to showcase new upcoming features. Every feature that will be in future releases must have been in a preview release at some point
  • The opposite is not true, the feature from a preview release will not necessarily be in the upcoming RC innovation release — this depends on whether the feature itself can be considered RC. If it isn't stable enough, it'll stay on internal testing and bugfixing until it is ready.

The release schedule looks about the same every year:

  • Every third month there's a new minor innovation release and new patch versions maintenance releases:
    • early February, early May, early August, early November
  • Preview releases happen between innovation releases:
    • mid-March, mid-June, mid-September, mid-December
  • New major release every second year
    • early February on even years (with a preview in mid-December)

Historical MariaDB Release Models

from 10.2 to 10.6

  • There is a new release series *every year*
  • It's maintained for five years after the first GA release
  • A release was going through conventional alpha, beta, RC maturity phases until reaching GA
  • The first GA was planned to happen in May

from 10.0 to 10.1

  • It is a feature based model
  • a new release series was supposed to have a specific set of features
  • it was released when they were ready
  • no fixed or predictable schedule, “it’s ready, when it’s ready”
