okhttp 3.4.0 RC1 发布了，更新如下： 改写了 HttpURLConnection 和 HttpsURLConnection. Cipher suites 现在可能有任意的名称。 Fix: CertificatePinner now matches canonicalized hostnames. Fix: Don’t crash on non-ASCII ETag headers. Previously OkHttp would reject these headers when validating a cached response. Fix: Don’t allow remote peer to arbitrarily size the HPACK decoder dynamic table. Fix: Honor per-host configuration in Android’s network security config. Previously disabling cleartext for any host would disable cleartext for all hosts. Note that this setting is only available on Android 24+. New: HPACK compression is now dynamic. This should improve performance when transmitting request headers over HTTP/2. New: Dispatcher.setIdleCallback() can be used to signal when there are no calls in flight. This is useful for testing with Espresso. New: Upgrade to Okio 1.9.0. 下载地址： Source code (zip) Source code (tar.gz) okhttp 3.4.0 RC1 发布，HTTP+SPDY 客户端开发包下载地址
