okhttp v3.3.0 Release Notes

  • 2016-05-24

    • New: Response.sentRequestAtMillis() and receivedResponseAtMillis() methods track the system's local time when network calls are made. These replace the OkHttp-Sent-Millis and OkHttp-Received-Millis headers that were present in earlier versions of OkHttp.
    • New: Accept user-provided trust managers in OkHttpClient.Builder. This allows OkHttp to satisfy its TLS requirements directly. Otherwise OkHttp will use reflection to extract the TrustManager from the SSLSocketFactory.
    • New: Support prerelease Java 9. This gets ALPN from the platform rather than relying on the alpn-boot bootclasspath override.
    • New: HttpLoggingInterceptor now logs connection failures.

    • New: Upgrade to Okio 1.8.0.

    • Fix: Gracefully recover from a failure to rebuild the cache journal.

    • Fix: Don't corrupt cache entries when a cache entry is evicted while it is being updated.

    • Fix: Make logging more consistent throughout OkHttp.

    • Fix: Log plaintext bodies only. This uses simple heuristics to differentiate text from other data.

    • Fix: Recover from REFUSED_STREAM errors in HTTP/2. This should improve interoperability with Nginx 1.10.0, which [refuses][nginx_959] streams created before HTTP/2 settings have been acknowledged.

    • Fix: Improve recovery from failed routes.

    • Fix: Accommodate tunneling proxies that close the connection after an auth challenge.

    • Fix: Use the proxy authenticator when authenticating HTTP proxies. This regression was introduced in OkHttp 3.0.

    • Fix: Fail fast if network interceptors transform the response body such that closing it doesn't also close the underlying stream. We had a bug where OkHttp would attempt to reuse a connection but couldn't because it was still held by a prior request.

    • Fix: Ensure network interceptors always have access to the underlying connection.

    • Fix: Use X509TrustManagerExtensions on Android 17+.

    • Fix: Unblock waiting dispatchers on MockWebServer shutdown.
