Change Log Overview

The change log contains a detailed summary of the changes made for each new release of QuantaStor. Each change made to QuantaStor is tracked with an engineering ticket number in the form [QSTOR-NNNN]. This information is provided so that if you're working with OSNexus support you can track the availability of a given product feature add, improvement, or maintenance fix to a specific release. For information on how to upgrade your storage system please see the Upgrade Guide.

Versioning System

QuantaStor version numbers consist of four (4) parts. A major number (M), minor number (N), maintenance update number (U) and build number (B) of the form M.N.U.B such as

QuantaStor upgrades go directly from whatever version you are running to the latest version, with no interim steps so for example if you are at v6.0.1 you will upgrade directly to the latest version which may be v6.1.2

Product Update Types

Major Updates (X.y.z)

If the first digit in the version number has changed this indicates a major product release such as QuantaStor v5 to QuantaStor v6. Major releases generally come with a new underlying Linux platform as the basis. For example, the standard ISO install for QuantaStor v5 is based on Ubuntu 18.04 whereas QuantaStor v6 is based on Ubuntu 20.04. Major product releases generally include new features and maintenance updates and are supported on multiple underlying Linux platforms. For example, QuantaStor v6 is available as an upgrade on Ubuntu 18.04 and Ubuntu 20.04 based systems as well as RHEL and RHEL derivative platforms. Platform upgrades to move systems forward (eg 18.04 to 20.04) are made generally available in the first feature update release, such as QuantaStor 6.1.

Feature Updates (x.Y.z)

If the second digit in the version number has changed this indicates a feature release such as 6.1 going to 6.2. Feature releases add new product features as well as a maintenance updates. No additional licensing is required to access any new features that added but note that QuantaStor licenses do not include licenses for 3rd party products and services that may integrate with QuantaStor.

Maintenance Updates (x.y.Z)

If the third digit of the version number has changed this such as 6.0.2 or 6.0.3 it represents a maintenance update to address one or more support tickets. These updates generally do not contain new features, only fixes to address specific issues. Maintenance releases generally ship every 4 to 8 weeks. All maintenance "aka hot-fix" releases are provided against the current stable release so upgrading to the latest QuantaStor version is generally required to apply them.

Build Number (x.y.z.BBB)

The build number and corresponding build reference hash can be largely ignored. The build number simply increments with each commit that is made to the source tree. The hash is provided to make it easier for OSNEXUS support and engineering to quickly confirm difference between your current running release and any more modern release.
