本次更新内容如下：

• OkHttp's new okhttp-tls submodule tames HTTPS and TLS.

• OkHttp now supports prior knowledge cleartext HTTP/2

• New: HttpUrl.get(String) is an alternative to  HttpUrl.parse(String) that throws an exception when the URL is malformed instead of returning null. 

• New: The EventListener API previewed in OkHttp 3.9 has graduated to a stable API. 

• New: okhttp-dnsoverhttps is an experimental API for doing DNS queries over HTTPS. 

• New: okhttp-sse is an early preview of Server-Sent Events (SSE). 

• New: MockWebServer now supports client authentication (mutual TLS).

• New: RecordedRequest.getHandshake() returns the HTTPS handshake of a request sent to  MockWebServer .

• Fix: Honor the MockResponse header delay in MockWebServer.

• Fix: Don't change Conscrypt configuration globally.
