Semver Minor

• Added support for UDP multicast. (#618)
• Improved detection of users calling EventLoopFuture.wait() on some EventLoo p types. (#553)
• Added diagnostics to EventLoopFuture.wait() to ensure users can locate the c
  all on error. (#578)
• Added SocketOptionProvider protocol to provide nicer API for setting socket options. (#589)
• Conformed Slice, UnsafeBufferPointer, and UnsafeMutableBufferPointer to ContiguousCollection to improve write speeds. (#586)
• Add @discardableResult to ByteBuffer.readWith* methods. (#549)
• Improved HTTPHeaders.isKeepAlive to check all values in Connection header. (#414)
• Made HTTPHeaderIndex & HTTPHeader structures public, as well as HTTPHeade rs.createHeaderBlock(buffer:headers:) and HTTPHeaders.withUnsafeBufferAndIndices. (#525)
• Improved style around memory bindings. (#541)

Semver Patch

• Fixed potential deadlock in BlockingIOThreadPool. (#634)
• Fixed compilation errors on Android. Android is not covered by CI at this time, so this may regress. (#609)
• Fixed IdleStateHandler to propagate channelActive. (#615)
• Emit IP address in SocketAddress.description. (#601)
• Improved error reporting so that hitting blacklisted errno values will print
  strerror rather than a string pointer. (#610)
• Updated HTTP parser. (#627)
• Correctly use umbrella headers for our C modules, reducing compiler errors. (#636)
• Clean up some warnings and future compiler errors. (#605, #623)
• Documentation improvements. (#613, #619)
• Testing improvements. (#611, #616, #621, #625)

This release contains no code changes, and is exists purely for administrative purposes.

This release contains no code changes, and is exists purely for administrative purposes.

Semver Patch

• Removed an unnecessary import in CNIOAtomics that could cause clang to error out when compiled in strict warnings modes. (#561)
• Removed an implicit integer conversion in CNIODarwin that could cause clang to error out when compiled in strict warnings modes. (#566)

Semver Minor

• Added an API for scheduling repeated tasks on an EventLoop, via EventLoop.scheduleRepeatedTask, as well as a new RepeatedTask type. (#488)
• Made CircularBuffer conform to BidirectionalCollection, RandomAccessCollection, and RangeReplaceableCollection, substantially increasing its utility. (#466)
• Split error-handling for WebSocketFrameDecoder out to a new ChannelHandler, WebSocketProtocolErrorHandler. Allowed users to disable the default error handling to implement their own. (#528)
• Added support for non-blocking file writes with NonBlockingFileIO.write. (#531)
• Added support for iterating over all EventLoops in an EventLoopGroup. (#509)
• Deprecated ByteBuffer.changeCapacity, replaced it with ByteBuffer.reserveCapacity. Improved performance. (#539)
• Added two typealiases for internal data structures to the public declaration of ByteBuffer, _Index and _Capacity. These are public to work around a limitation of older Swift 4 releases, and should not be used from user code. (#494)

Semver Patch

• Silenced some warnings. (#456)
• Prevented 100% CPU hot-looping on macOS when using autoRead false. (#526)
• Fixed rare crash in example WebSocket server. (#472)
• Fixed an issue where creating a ByteBufferView over the entire storage of a ByteBuffer would cause a crash. (#482)
• Fixed the example HTTP server to correctly respond to multiple pipelined dynamic requests on the same connection. (#468)
• Changed the docker-compose configuration to line-buffer output to the console. (#491)
• Fixed logical processor enumeration to use faster, cross-platform API. (#496)
• Improvements to code internals on 32-bit platforms. (#503)
• Correctly handle ContiguousCollection implementations that provide pointers that are larger than the number of elements they report with .count. (#501)
• Improved HTTPServerUpgradeHandler to treat protocol upgrade names case-insensitively. (#520)
• Fixed a bug where we could inadvertently produce no-op events to SelectableEventLoops instead of ignoring them. (#521)
• Forward debugging information when chaining Futures using mapIfError. (#533)
• Updated http_parser. (#471)
• Removed unnecessary memory binding in Thread. (#542)
• Documentation improvements. (#460, #461, #462, #464, #535)
• Testing improvements. (#504, #512, #513)
• Minor code cleanups. (#511, #543)
