FS2 v0.9.5 Release Notes

    • Fixed memory leak in concurrent.join where up to maxOpen streams that had finished executing were kept in memory until the end of the outer stream was reached. #834
    • Fixed a bug in fs2.io.JavaInputOutputStream, ensuring bytes are converted to 0-255 before being returned.
    • Added pipe2.pause and Stream#pause combinators -- similar to interrupt but allows the stream to be resumed.
    • Added Stream#evalScan - a variant of scan where the supplied function returns an effectful value.
    • Added pipe.unNone and Stream#unNone, which converts a Stream[F, Option[A]] to a Stream[F, A], ignoring any None values.
