    backwards-incompatible changes in forthcoming releases.
 *  Fix: Don't crash loading the public suffix database resource in obfuscated builds.
 *  Fix: Don't silently ignore calls to `EventSource.cancel()` made from
    `EventSourceListener.onOpen()`.
 *  Fix: Enforce the max intermediates constraint when using pinned certificates with Conscrypt.
