Release notes
Version history for Tetrate Agent Router. Every release has its own page listing its security updates, new features, bug fixes, and deprecations, together with upgrade and rollback notes for platform operators. Security updates name the CVEs a release fixes as identifiers, and an update with no identifier assigned says so; vulnerabilities without a shipped fix are not listed.
Releases are cut every Wednesday, and a patch ships when it is needed rather than waiting for the next cut. Each release is supported for six months from the day it ships, and every release below carries its end-of-support date. The window applies to the release an operator runs, the self-hosted data plane and the tare CLI, since the Tetrate-hosted management plane is always current. Supported means the management plane keeps working with that release until the date; fixes are not backported, so getting a fix means upgrading to a release that contains it. The supported releases listed on this page are the published list of versions that the Maintenance and Support Terms refer to as Supported Software.
What each supported release requires and ships is listed on Release compatibility, and deprecations across releases are tracked on Deprecations.
