Releasing of the Reliance SCADA/HMI system's versions

October 2, 2013 | Bretislav Valek

To name its versions, the Reliance system uses a sequence of numbers separated by periods: major.minor.release (e.g., Reliance 4.6.0). For a version's unique identification, also the revision number is sometimes used, i.e., major.minor.release.revision (e.g., Reliance The revision can also be shown separately, e.g., Reliance 4.6.0, Revision 19532.

Meaning of each given version number category

The major category specifies the main number of a Reliance version. Usually, major versions are released at an interval of several years. Upgrades to higher major versions are not free of charge.

The minor category is used to distinguish significant changes made to the Reliance system within a single major version. Minor versions are not released regularly. Upgrades between minor versions are free of charge.

The release category is used to distinguish official versions of Reliance. Such versions are released once every 2-3 months. Upgrades are free of charge.

The revision category specifies a unique identifier of the Reliance source code version (the so-called revision). It is used, for example, to distinguish two Pre-release versions.

A version can be supplemented with additional information. First, it can be the so-called update, which is a repair of a specific version, such as Reliance 4.5.2, Update 1. It can also be the so-called Pre-release version, such as 4.6.1 Pre-release. More information on Pre-release versions can be found further in the article.
