v0.10.0-M8

For cats 1.0.0-RC1 and cats-effect 0.5.

• Fixed a memory leak reported by @epellizzer where scopes were not being properly garbage collected (#962)
• Fixed a performance issue in Stream#flatMap reported by @grindvoll (#958)
• Renamed >> to *> in order to be consistent with cats
• Fixed a bug where runSync was accidentally requiring an Effect instance instead of a Sync instance
• Added Segment.unfoldChunk
• Changed Segment#run so that it requires the output type to be Nothing instead of Unit. Use drain to drop the output values
• fs2.async.Ref constructor is now private -- use fs2.async.ref or fs2.async.refOf methods to allocate a ref
• Added scope method to Stream for manually inserting scope boundary
• Added streamNoScope method to Pull for converting a Pull to a Stream without inserting a scope boundary
• Miscellaneous internal cleanup

v0.10.0-M7

• Changed translate so that it no longer requires an implicit Effect[F] instance and removed translateSync. Modified run methods on Stream so that they require an Effect[F] and introduced weaker variants (runSync, runFoldSync, runLogSync, etc) that only require a Sync[F] and fail if they encounter an UnconsAsync step.
• Fixed bug in dropThrough where an extra element was dropped if the last element of a segment failed the predicate (#946)
• Fixed bug where zip and other stream interleaving combinators could result in errors indicating scope is already closed (#945)
• Fixed bug in hash where chunk offsets were ignored - from @SystemFw (#944)
• Added ScalaDoc regarding implicit cats instances for Stream - from @jdnavarro (#942)
• Added Segment#flatMapResult - from @avakhrenev (#940)
• Fixed typos in ScalaDoc - from @BenFradet (#938)
• Fixed NullPointerException in Segment#flatMap - from @tscholak (#937)
• Added Stream#observe1 as an alias for evalMap(o => f(o).as(o))
• Changed behavior of scan so that it eagerly emits values and matches rx specification - from @avakhrenev (#931)
• Replaced internal primitive uses of Array.ofDim with new Array[..] to avoid class manifest locking
• Performance improvements in fs2.udp - from @sbuzzard (#927)

v0.10.0-M6

• Added timeout support to many async data structures (Ref#timedGet, Queue#{timedEnqueue1,timedDequeue1,timedDequeueBatch}, Semaphore#{timedDecrement,timedDecrementBy})
• Added various methods to Scheduler including fixedRate and fixedDelay
• Added Scheduler#effect API for working with time delayed effects
• Added fs2.io.file.watch API for watching files/directories for changes

v0.10.0-M5

• Upgraded to cats-effect 0.4 and cats 1.0.0-MF
• Added retry and attempts to Scheduler

v0.10.0-M4

• Changed flatMap on Stream so that recursive flatmaps on singleton streams run in constant memory.
• Restored Pipe.Stepper and Pipe2.Stepper (which no longer leak memory).
• Ref#setSync now correctly sets the value before completing the returned task.
• Fixed an intermittent bug with rare stream shapes where an IllegalArgumentException was thrown while running a stream with async uncons calls.
• Removed the fs2.time object and moved its methods to Scheduler.
• Added support for shutting down Schedulers on the JVM, where each scheduler is backed by a thread pool.

v0.10.0-M3

• Fixed a memory leak in FreeC by removing ViewL caching
• (Temporarily) removed Pipe.Stepper and Pipe2.Stepper due to an unsolved memory leak
• Added various methods to Segment -- flatMap, flatten, mapConcat, flattenChunks

v0.10.0-M2

• First milestone build using new API

v0.10.0-M1

• Same design as 0.9 but with the fs2.util package replaced by a direct dependency on cats and cats-effect
