Release cycle
ASM typically updates the list of supported Istio major versions every three months.
After a major version is released, ASM occasionally releases patch versions (such as 1.18.x.y) to provide new features and fix vulnerabilities.
ASM may automatically perform a hot update on a patch version (such as from v1.18.0.123 to v1.18.0.146) without prior notification. During an automatic hot update, the versions of the data-plane gateways and sidecar proxies remain unchanged.
Risks of expired versions
ASM instances of expired versions pose security and stability risks. We recommend that you update ASM instances in a timely manner. We do not promise to provide security patches or fix issues for ASM instances of expired versions, nor guarantee the quality of technical support for these instances.
