Release Notes

The Ontotext Platform release notes provide information about the features and improvements in each release, as well as various bug fixes. Ontotext Platform’s versioning scheme is based on semantic versioning. The full version is composed of three components:

major.minor.patch

e.g., 1.2.3 where the major version is 1, the minor version is 2, and the patch version is 3.

Note

Releases with the same major and minor versions do not contain any new features. Releases with different patch versions contain fixes for bugs discovered since the previous minor. New or significantly changed features are released with a higher major or minor version.
