On June 6, 2023, the following was included in the release notes for Release 0.0.195.
Change to the support window for on-prem release versions: Due to the frequency of our releases and rapid changes to our product, we will now only offer dedicated support for releases up to two months prior to the current release version. For versions older than this we will provide best-efforts support. If you are currently using a release older than two months, we highly recommend updating to the latest release. If you encounter an issue while using a version of Cortex older than two months, you may be asked to upgrade as part of our ongoing support efforts.
