0.17.0: Add mergeConcurrently, continueWith, recoverWith

• Add continueWith and recoverWith as new preferred aliases for flatMapEnd and flatMapError
• Make mergeConcurrently public
• Improve performance of multicast and continueWith (aka flatMapEnd)
• Simplify resource handling and disposal

0.16.0: Improve scan and scheduler

• Make scan preserve stream end signal value.
• Improve scheduler internals to reduce load when using lots of timer-based combinators, like delay

0.15.0: Add browser dist build, improve async handling, add multicast

• Add browser build in dist/most.js and dist/most.min.js
• Make most.create call producer function synchronously.
  • Events are still always asynchronous to prevent zalgo.
• Add multicast combinator for more efficiently sharing streams among many consumers.
• Fix bug related to specific cases of handling event at time zero.
  • This manifested with skipUntil/since ending early or appearing to be an empty stream.
• Improve scheduler internals.
• Improve drag-n-drop example.

0.14.0: Prepare for 1.0.0

• Preparing for upcoming 1.0.0.
• Promote during to non-experimental.
• Fix most.create multiple consumer handling when streams end early (e.g. using until, take, etc.)
• Remove deprecated APIs:
  • most.repeat - use most.periodic, most.iterate, or most.unfold
  • most.fromEventWhere - use most.fromEvent plus filter
  • distinct and distinctBy - use skipRepeats and skipRepeatsWith

0.13.2: Add skipRepeats

• Add skipRepeats and skipRepeatsWith as new preferred names for distinct and distinctBy.
  • The names distinct and distinctBy are now deprecated.
• Improve handling of EventEmitter subscriptions in fromEvent.
• Optimize fromArray
• Fix for debounce dropping the last event when a stream ended early (e.g. via until).
  • If, when the stream is about to end, there is a pending debounced event, that event will be propagated just before end. The event and end will have the same timestamp.

0.13.1: Support new transducer protocol

• Update transducer support for new official transducer protocol. See cognitect-labs/transducers-js#20.
  • 0.13.1 supports both the older protocol and the new protocol, so will work with transducer libs supporting either protocol.
  • Support for the old protocol is considered deprecated, and will be removed in an upcoming version.

0.13.0: Transducers, recipes, and more fusion

• Add most.transduce and stream.transduce for transducer support for cognitect-labs/transducers-js, jlongster/transducers.js, and any transducer impl that supports the same protocol.
• Add recipes showing how to solve common and interesting use cases. Community contributions very welcome!
• Fuse adjacent map and filter combinators even further. In addition to the level of fusion that is already done for all combinators, chains of map and filter are now fused into a single step.
• Improve and simplify timeslice combinators (since, until, and during)
• Fix an issue with since which caused it to ignore end-of-stream.
• Fix an issue with some examples not loading.

0.12.0: Async generators and improved sampling

• Add most.generate to build a stream by running an async generator.
• Add sampler.sample(f, ...streams) for sampling and combining many streams at once.
• Improve stream.ap. It now more closely models the behavior of applying a time varying function to a time-varying value.
• Change stream.combine to end when all input streams have ended.
  • Breaking change: code that specifically depends on a combine stream ending when only one input ends may need to be updated.

0.11.0: Add loop and periodic w/value

• Add stream.loop: generalized feedback loops
• Add value to most.periodic: most.periodic(period, value) produces value every period ms.
• Improve stream.distinct performance
• Fix rejected promise handling in most.fromPromise and stream.await

0.10.2: Improve zip and scan perf

• Improve zip and scan performance. In many cases, they can be 2-3x faster.
• Switch to benchmark.js for performance testing.
