     * users only see documents they are authorized to access.

     * This is the primary extension point for subclasses to customize search behavior.
     *
     * @param query the search query
     * @param fields the field filters (e.g., label)
     * @param extraQueries the extra query filters (e.g., filetype, timestamp)

 *  **OkHttp no longer attempts a direct connection if the system's HTTP proxy fails.** This
    behavior was surprising because OkHttp was disregarding the user's specified configuration. If
    you need to customize proxy fallback behavior, implement your own `java.net.ProxySelector`.

 *  Fix: Support TLSv1.3 on devices that support it.

 *  Fix: Share pooled connections across equivalent `OkHttpClient` instances. Previous releases had

`.keras` extension. This file format targets the Python runtime only and makes it possible to reload Python objects identical to the saved originals. The format supports non-numerical state such as vocabulary files and lookup tables, and it is easy to customize in the case of custom layers with exotic elements of state (e.g. a FIFOQueue). The format does not rely on bytecode or pickling, and is safe by default. Note that as a result, Python `lambdas` are disallowed at loading time. If you want to use `lambdas`,...
