We are excited to announce a change in our software versioning system! This new system will make it easier for you to track releases by showing both their order and year, providing clearer insight into our updates and patches. Moving forward, we will use a new format: YEAR.MINOR_RELEASE.PATCH_LEVEL, where:
  • YEAR is the year of the release, for example, 2025.
  • MINOR_RELEASE is the Nth minor release of the year, for example, the 10th minor release in 2025 is 10.
  • PATCH is the Nth patch for a minor release, for example, the 1st patch for the 10th minor release is 1. If no patches are released, the number is 0.
This page provides a list of removals and deprecations for native Cognigy features, as well as those that rely on third-party dependencies, such as LLMs (Large Language Models), Endpoints, and other external connectors.

​
Terminology

  • Deprecations. A feature is considered as outdated and no longer recommended for use, with support limited to critical fixes only. The deprecation process starts with an announcement and continues until the feature is removed in future releases.
  • Removals. A feature is completely removed and no longer supported after the specified removal date.

Third-Party Products

The table lists LLMs that are deprecated and will be shut down soon. Once the LLM provider removes the model, it will stop working in Cognigy.AI. This change could cause disruptions to your AI Agent if the model is still being used in the Flow. If you’ve added models from the list as custom models in Cognigy.AI, switch to newer models before the shutdown date.
