### The extended Hot Code Replace (HCR) capability disabled and `-XX:[+|-]EnableExtendedHCR` option added

By default, the extended Hot Code Replace (HCR) capability in the VM is disabled for all OpenJDK versions. You can enable or disable the HCR capability by using the [`-XX:[+|-]EnableExtendedHCR`](xxenableextendedhcr.md) option.
By default, the extended HCR capability in the VM is disabled for all OpenJDK versions, which is a change from the previous releases. You can enable the HCR capability by using the new option, [`-XX:+EnableExtendedHCR`](xxenableextendedhcr.md) option.

The extended HCR feature is deprecated in this release and will be removed in a future release. From OpenJDK 25 onwards, extended HCR will not be supported. Following that, the extended HCR support will be removed from other earlier OpenJDK versions also.
