      * Fix `FlowControlHandler` behaviour to pass read events when auto-reading is turned off
      * Fix brotli compression
      * Fix a bug in FlowControlHandler that broke auto-read
      * Fix a potential memory leak bug has been in the pooled allocator
      * Fix a scalability issue caused by instanceof and check-cast checks that lead to false-sharing on the         `Klass::secondary_super_cache` field in the JVM
      * Fix a bug in our `PEMParser` when PEM files have multiple objects, and `BouncyCastle` is on the     classpath
      * Fix several `NullPointerException` bugs
      * Fix a regression `SslContext` private key loading
      * Fix a bug in `SslContext` private key reading fall-back path
      * Fix a buffer leak regression in `HttpClientCodec`
      * Fix a bug where some `HttpMessage` implementations, that also implement `HttpContent`, were not     handled correctly
      * Fix epoll bug when receiving zero-sized datagrams
      * Fix a bug in `SslHandler` so `handlerRemoved` works properly even if `handlerAdded` throws an     exception
      * Fix an issue that allowed the multicast methods on `EpollDatagramChannel` to be called outside of an     event-loop         thread

      * Fix a bug that caused an error when files uploaded with HTTP POST contained a backslash in their name
      * Fix an issue in the `BlockHound` integration that could occasionally cause NetUtil to be reported as     performing         blocking operation. A similar `BlockHound` issue was fixed for the `JdkSslContext`
      * Fix a bug that prevented preface or settings frames from being flushed, when an HTTP2 connection was     established         with prior-knowledge

      * Fix and relax overly strict HTTP/2 header validation check that was rejecting requests from Chrome and     Firefox
      * Fix OpenSSL and BoringSSL implementations to respect the `jdk.tls.client.protocols` and     `jdk.tls.server.protocols`         system properties, making them react to these in the same way the JDK SSL provider does
      * Fix inconsitencies in how `epoll`, `kqueue`, and `NIO` handle RDHUP
