We are happy to announce the final release of Istio 1.4 with Istio 1.4.10. This includes bug fixes as well as the fix for the CVE announced June 11th. Please see the release notes here https://istio.io/latest/news/releases/1.4.x/announcing-1.4.10/ . The CVE was reported shortly before the EOL for 1.4 and the Istio community decided to back-port the changes for 1.4, even though support for 1.4 ended shortly thereafter.
Thank you to all that supported this release.
