SwiftNIO 1.4.1

Semver Patch

• Restore unary initializer for HTTPHeaders. (#301)

SwiftNIO 1.4.0

Semver Minor

• More strictly enforced channel lifecycle tracking. This will cause new errors to be thrown if channels are mishandled by the NIO core. (#220)
• Added EventLoopFuture.fold. (#269)
• Added EventLoopFuture.reduce and EventLoopFuture.reduce(into:). (#240)
• Added a HTTP server handler that can send 400 errors on HTTP parser errors. (#268)
• Renamed HTTPHeaders.getCanonicalForm to HTTPHeaders[canonicalForm:], deprecated the old interface. (#293)
• Made several ByteBuffer generic methods inlinable. (#266)
• Implemented lazy HTTP header parsing. Users, please note that this may change the casing of your HTTP headers. (#291)

Semver Patch

• Changed graceful event loop shutdown to properly wait for channel shutdown. (#231)
• Removed needless availability check restricting use on older macOS platforms. (#233)
• Reduced locking overhead in the EventLoop. (#235)
• Removed overhead in SocketChannel, ServerSocketChannel, DatagramChannel, and PendingDatagramWriteManager relating to the removed flush promises. (#234)
• Removed unnecessary promise allocation in Selector.closeGently. (#237)
• Cleaned up ordering in EmbeddedChannel connect and close with respect to promises and channelActive/channelInactive. (#241)
• Improved PriorityQueue and Heap performance by bringing them into the NIO module. (#245)
• Reduced the duplication of results in getaddrinfo lookups. (#221)
• Reduced storage overhead of ChannelHandlerContext. (#247)
• Avoided re-arming timerfd on Linux when doing so was not necessary. (#264)
• Improved performance of allocation operations in ByteBuffer. (#267)
• Improved performance and reduced allocation in HTTPDecoder. (#275)
• Added WebSocket documentation. (#276)
• Enhanced HTTPDecoder to reject HTTP 0.9 and any misleading HTTP/1.1-style protocol that claims a HTTP/2 or higher version. (#283)
• Fixed some TSAN issues.
• Reduced the number of read calls in most cases. (#296)
• Improved the performance of outbound channel operations. (#297)
• Cleaned up typos and other code. (#230, #236, #259, #273)

SwiftNIO 1.3.1

Semver Patch

• Fixed build issues on Swift 4.1 snapshots. (#229)

SwiftNIO 1.3.0

Semver Minor

• Gave HTTPResponseStatus a public initializer that can take a numerical status code and optional reason phrase and create an appropriate enum member, instead of forcing users to use .custom. (#158)
• Added EventLoopFuture.hopTo(eventLoop:) to simplify code that needs to ensure callbacks dispatch to a specific thread. (#177)

Semver Patch

• Suppressed compiler warnings that were emitted in release mode. (#179)
• Fixed compilation on iOS. (#180)
• Fixed possible infinite loop when shutting down event loops. (#188)
• Brought EmbeddedEventLoop's task scheduling behaviour closer to that of MultiThreadedEventLoop. (#189)
• Fixed ordering issues between promises and fire* methods. (#181)
• Fixed failure to expose backwards-compatibility shim for HTTP header iterator type. (#194)
• Reduced memory allocation during task dispatch on MultiThreadedEventLoopGroup. (#192)
• Fixed ordering issues where fireChannelRead could dispatch before fireChannelActive. (#195, #204)
• Fixed issue where Happy Eyeballs connection state machine would fatalError under high load. (#191)
• Correctly fail the futures returned from Channel.getOption and channel.setOption when the channel is closed. (#198)
• Improved error message when a non-synchronous connect fails. (#203)
• Correctly make the channel active when connect succeeds synchronously. (#205)
• Better diagnostic logging when leaking an EventLoopPromise allocated from ChannelOutboundInvoker. (#208)
• Don't crash when a selectable is unregistered from a selector while there are pending select events for that selectable. (#210)
• Don't retry close when the syscall returns with EINTR. (#217)
• Work around performance penalty from SR7242. (#223)
• Prevent users getting access to or removing HeadChannelHandler and TailChannelHandler. (#225)
• Correctly fail EventLoopPromise for writes on ServerSocketChannel instead of crashing. (#226)
• Miscellaneous documentation and code style improvements (#207, #212, #219, #197, #142, #193, #87, #190, #183)
