Changelog

All notable changes to the viktor SDK will be documented in this file, categorized by version number.

The changes can be categorized further in the following headers:

  • Action Required: when a backwards incompatible change is made, which requires actions in the application code. This header will only be present in major releases, on Beta features, or when a Python version is dropped.
  • Added: when a functionality is added, without breaking compatibility with older versions.
  • Deprecated: when an existing functionality will be removed in upcoming releases. You will find a reference to the upgrade instructions in this change.
  • Docs: when the change involves SDK documentation, docstring, and/or type hinting.
  • Fixed: when the change fixes a bug/error.
  • Security: when a vulnerability is fixed.

Each change consists of a tag to annotate which VIKTOR module is involved. If the change encompasses multiple modules, the viktor tag is used.
