### Stay up to date

The elasticsearch build usually uses the latest Gradle GA release. We stay as close to the
latest Gradle releases as possible. In certain cases an update is blocked by a breaking behaviour
in Gradle. We're usually in contact with the gradle team here or working on a fix
in our build logic to resolve this.

  /**

   * vertical transformation, and vice versa. The inverse of the {@link #forNaN} transformation is
   * itself. In all other cases, the inverse is a transformation such that applying both the
   * original transformation and its inverse to a value gives you the original value give-or-take
