SwiftNIO 1.4.0

on GitHub

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)
