List of Releases

The SSR software follows a semantic versioning scheme. Semantic versioning is a simple scheme built around the name-X.Y.Z-build-milestone concept. X is incremented for every major release. A major release can be the introduction of major features or when backwards compatibility may be broken. Y is a minor release with solely non-breaking feature additions. Z is designated for bug fixes in previous releases. -build is used to denote the incremental process of development until the culmination in the final release. -milestone can be one of r1, r2, sts or lts.

Starting with version 5.4.0 the -build will reflect the number of iterations the release candidate went through prior to release. The build number will never increment once the software has been released. The build number will be included in the release notes for the respective version.

Version 6.1.0 introduces the milestone suffix to the SSR software release model. Every six months, a new SSR software stream (i.e., bump in Major or Minor) will be released. Each software stream (major.minor) will have three phases of release - R1, followed by R2, followed by a final release. Initial feature content for a stream will be known as R1 (Release candidate 1). R1 will be followed by additional feature content three months later in an R2 (Release candidate 2). Between R1 and R2, there may be patch releases. Once R2 is released, a customer must upgrade to R2 to remain on the same stream and address any defects identified in R1. Three months following R2, the release will be designated as either Standard Term Support (STS) or Long Term Support (LTS). Every other release stream will be designated as LTS (Long Term Support). The EoSE dates for STS or LTS start once the software is labeled with the sts or lts suffix, respectively; not based on the FRS date.

info

Issues resolved in a release are merged into subsequent releases chronologically AND lexicographically.

For example, issues resolved in 4.3.12, which was released on 3/12/2021, are resolved in 4.5.6, which was released on 3/26/2021 and also resolved in 5.1.0, which was released on 3/15/2021, and so on.

However, issues resolved in 4.3.12, which was released on 3/12/2021 are not addressed in 4.5.5 because 4.5.5 was released on 2/10/2021. Even though 4.5.5 is lexicographically higher than 4.3.12, it is chronologically older than 4.3.12.
