Versioning of Modules in On-Premise Bitrix24
If you are developing integrations for Bitrix24 using AI tools (Codex, Claude Code, Cursor), connect to the MCP server so that the assistant can utilize the official REST documentation.
When developing applications, it's important to consider that the REST methods and events available for use in cloud Bitrix24 may not be accessible in specific on-premise installations.
Firstly, the release schedule for updates in Bitrix24 for the on-premise version differs from that of the cloud version, as these updates require a separate testing cycle, among other considerations.
Secondly, obtaining updates in on-premise installations occurs "at the initiative" of the specific on-premise installation. In other words, this process is initiated by the administrator of that particular on-premise Bitrix24, meaning that new features already available in cloud Bitrix24 may not "reach" the specific on-premise installation by the time your application is installed on it.
If users of your application encounter issues during operation on their on-premise version of Bitrix24 due to the absence of existing REST API functionality, and you, as the developer, do not have administrative access to that on-premise installation, you can refer to our documentation to provide users with information on which updates they need to download.
If you are the administrator of the on-premise installation, you can independently update Bitrix24 to the latest available version.
You can find the list of versions for all modules in the on-premise version in the administrative section: Settings > Product Settings > Modules.
