We are glad to announce streamly 0.9.0 release. streamly-0.9.0 and streamly-core-0.1.0 have been available on Hackage for some time now. You can find the source at https://github.com/composewell/streamly and reference documentation and some guides are also available on https://streamly.composewell.com . The website also has functionality to search across multiple streamly packages. This release did a major revamp of the API to make it easier to comprehend and less error prone to use. Now there is a single "Stream" type instead of the polymorphic "IsStream" type class. There are explicit concurrency combinators to enable concurrent behavior on the same type instead of using different types for that purpose. Dependency on GHC rewrite rules has been removed for more robust behavior and better programmer control, though it required splitting the stream type into the default direct-style type "Stream" and the CPS type "StreamK". The package has been split into two, "streamly-core" intends to depend only on boot libraries (currently has some more deps due to backward compatibility), "streamly" provides higher level functionality like concurrency. Parser functionality has been released. Parsers fuse with streams and are compatible with folds i.e. parsers are folds with more power. Please see the following docs for more details: * Changelog: https://streamly.composewell.com/streamly-0.9.0/User/ProjectRelated/Changelo... * Upgrade guide: https://streamly.composewell.com/streamly-0.9.0/User/ProjectRelated/Upgradin... Your feedback is important to us. We did the API revamp based on feedback from users. -harendra
