Version numbers in Business Central
Business Central online and on-premises consists of different components that must work together. If you are a an enduser, this doesn't matter in the course of your normal work day. But if you are an administrator, knowing the version numbers is important for troubleshooting, development, and on-premises upgrade scenarios.
You can use the information about which version the tenant is on to help you troubleshoot an issue that a user has reported, for example. This information is listed in the Troubleshooting section of the Help and Support page in Business Central in the following format:
|Platform <major>.<minor>.<build>.<revision>||15.0.12345.0||Specifies the full platform version, which includes client and server components.|
|Application <major>.<minor>.<build>.<revision>||15.1.23456.0||Specifies the full version number for the application, including the major version number and build number.|
In the Business Central administration center, the version information is rendered slightly differently:
|Platform <major>.<minor>||15.1||Specifies the major and minor version of the platform, which includes client and server components.|
|Application <major>.<minor>.<build>.<revision>||15.1.23456.0||Specifies the full version number for the application.|
The numbers are updated based on Microsoft's builds. In the default version of Business Central online, platform and application have the same major version number but different build numbers. If you perform a technical upgrade of Business Central on-premises, then platform and application will have different versions.
The following list describes the meaning of each of the numbers in a full version number:
majoris the major version of Business Central
15is the Business Central 2019 release wave 2 update in October 2019
14is the Business Central April 2019 release
13is the Business Central October 2018 release
12is the April 2018 launch of Business Central
minoris the monthly update number, such as 1 or 5.
buildis the five digit build number, such as 23456.
revisionis set to 0 for the original release and can remain at 0. However, if the tenant is patched with a hotfix, then that build number can be applied.
In other words, if you see a version number such as
15.1.23456.26323, then it means major version 15, update number 1, build number 23456, and hotfix number 26323.
The same version numbers are used in the on-premises Docker images that you can get for development purposes, and for the on-premises cumulative updates.
