# Changelog

All notable changes in the Konfuzio Server will be documented according to the principles defined by [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).

The changelog adheres to [Calendar Versioning](https://calver.org/overview.html) and the release tag relates to the date and time when those changes have been released to app.konfuzio.com. 

Self-hosted Konfuzio Server can be upgraded according to the [documentation](https://dev.konfuzio.com/web/on_premises.html#upgrade).

<!---
These changes are for the tokenizers/new SDK branch.

### Fixed
