    Nullability was previously ambiguous and lenient but now the compiler will
    enforce strict null checks.

 *  New: The response message is now non-null. This is the "Not Found" in the
    status line "HTTP 404 Not Found". If you are building responses
    programmatically (with `new Response.Builder()`) you must now always supply
    a message. An empty string `""` is permitted. This value was never null on

=== Potential breaking changes

 * Build will now fail if a specified init script is not found.
 * `TaskContainer.remove()` now actually removes the given task — some plugins may have accidentally relied on the old behavior.
 * <<#rel4.8:pom_wildcard_exclusions,Gradle now honors implicit wildcards in Maven POM exclusions>>.
