Support for Istio 1.15 ends on March 28th, 2023

According to Istio's support policy, minor releases like 1.15 are supported until six weeks after the N+2 minor release (1.17 in this case). Istio 1.17 was released on February 14th, and support for 1.15 will end on March 28th, 2023.

At that point we will stop back-porting fixes for security issues and critical bugs to 1.15, so we encourage you to upgrade to the latest version of Istio ({{<istio_release_name>}}). If you don't do this you may put yourself in the position of having to do a major upgrade on a short timeframe to pick up a critical fix.

We care about you and your clusters, so please be kind to yourself and upgrade.
