Release Notes¶
What’s in this document?
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.

Deployment and Operations Improvements - updates key components to newer versions and implements many improvements in the Helm charts, health checks, logging, etc.
Semantic Objects Service - provides additional mutation capabilities for writing in named graphs.
Semantic Search Service - enables the Semantic Search Service authentication and the skipping of malformed data indexing.
