# Feature Freeze

One week before a release, the release branch goes into a state of code freeze. At this point only critical release
blocking bugs are addressed. Additional changes that are targeted for new features and capabilities will not be merged.

The JVM running the Tooling API client and the one running the daemon can be different.
At the same time, classes that are sent to the build via custom build actions need to be targeted to the lowest supported Java version.
The JVM versions supported by Gradle is version-specific.
The upper bound is defined in the <<compatibility.adoc#compatibility,compatibility matrix>>.
