 * Fix problems where spdy/3.1 headers may not have been compressed properly.
 * Fix problems with spdy/3.1 and http/2 where the wrong window size was being
   used.
 * Fix 1.5.0 regression where conditional cache responses could corrupt the

```
$ emulator -no-window -no-snapshot-load @pixel5

2. Turn on logs with logcat

```
$ adb logcat '*:E' OkHttp:D Http2:D TestRunner:D TaskRunner:D OkHttpTest:D GnssHAL_GnssInterface:F DeviceStateChecker:F memtrack:F

    harmed connection reuse.
 *  Fix: Ensure canceled and discarded HTTP/2 data is not permanently counted against the limited
    flow control window. We had a few bugs where window size accounting was broken when streams
    were canceled or reset.
 *  Fix: Recover gracefully if the TLS session returns an unexpected version (`NONE`) or cipher
    suite (`SSL_NULL_WITH_NULL_NULL`).
