There are two versions of the platform releases:

  • stable version of the software. It comes out about once every three months;
  • regular version of the software. It usually comes out once a month.

We recommend using the stable version as it undergoes additional testing before release. Based on the results of testing, additional fixes and improvements are made to the stable version to optimize the performance of the software.

The regular versions include all functionality updates, but are less stable than the stable versions. Most of the features released in the regular versions are refined and then included in future stable versions.

The list of version changes is published on ISPsystem website.

Relationship of version functionality



Scheme of the relationship between versions


A new stable version is released after several versions of regular and includes:

  • functionality of the previous stable version;
  • functionality of the first regular version released between the two versions of stable;
  • fixes and improvements based on test results.

Fixes and improvements released in the stable version also make their way into the upcoming regular version.

In the example from the scheme, the stable 1 version includes:

  • functionality of stable 0;
  • functionality of regular 1.1;
  • fixes and improvements made between stable 0 and stable 1.

Most of the features from the regular 1.2, 1.3, ... , 1.6 will be included into stable 2.

Limitations of switching between versions

The platform does not support switching to a version with lower functionality. Therefore, when upgrading from regular to stable versions, the platform can only be updated after the release of a stable version that includes the functionality of the current regular version.

Examples with data from the scheme:

Example 1. The server has regular 1.1 version installed. Its functionality is identical to the stable 0 version. When upgrading to stable versions, the platform will be updated after the release of stable 1.

Example 2. The server has regular 1.2 version installed. Its functionality is greater than that of the stable 0 version. When upgrading to stable versions, the platform will be updated after the release of stable 2.

Example 3. The server has stable 1 version installed. When upgrading to regular versions, the platform will update to the latest released regular version.
