streamly-0.11.0 and streamly-core-0.3.0
<https://github.com/composewell/streamly> are now available on Hackage. Use=
r
guides
<https://streamly.composewell.com/streamly-0.11.0/Tutorials/why-haskell-str=
eamly.html>,
combined reference and Hoogle search
<https://streamly.composewell.com/search.html?query=3D&ecosystem=3Dstreamly=
-0.11.0-ecosystem.hoo>
across all Streamly ecosystem packages can be found on the Streamly website
<https://streamly.composewell.com/index.html>.

Important features in this release are:

   -

   *Scans with Scanl*: The new Streamly.Data.Scanl
   <https://streamly.composewell.com/haddocks/streamly-core-0.3.0/Streamly-=
Data-Scanl.html>
   module allows you to compose multiple stateful transformations (i.e. sca=
ns)
   on a stream. You can split a stream into multiple constituent streams,
   process each independently, and then merge the results. With
   Streamly.Data.Scanl.Prelude
   <https://streamly.composewell.com/haddocks/streamly-0.11.0/Streamly-Data=
-Scanl-Prelude.html>,
   you can compose concurrent scans i.e. each branch of the split scan can =
run
   in a different thread.
   -

   *New concurrent fold combinators*: Extended Streamly.Data.Fold.Prelude
   <https://streamly.composewell.com/haddocks/streamly-0.11.0/Streamly-Data=
-Fold-Prelude.html>
   with some powerful concurrent fold combinators.
   -

   *Deterministic resource cleanup*: Introduced APIs that guarantee timely
   resource release, eliminating reliance on GC-based cleanup. The library =
now
   offers low-level IO primitives and high-level stream combinators for
   resource management =E2=80=94 everything you can do with resourcet, and =
more, is
   built in.
   -

   *Fair nesting of streams*: Added operations that interleave inner and
   outer streams fairly, ensuring balanced exploration. Particularly powerf=
ul
   for logic programming.
   -

   *Circular buffers*: Added Streamly.Data.RingArray
   <https://streamly.composewell.com/haddocks/streamly-core-0.3.0/Streamly-=
Data-RingArray.html>,
   a high-performance, unboxed circular buffer.
   -

   *File system paths*: Streamly.FileSystem.Path
   <https://streamly.composewell.com/haddocks/streamly-core-0.3.0/Streamly-=
FileSystem-Path.html>
   module leverages streamly arrays, and streams for performance and
   flexibility, provides better safety, and is intended for gradual type sa=
fe
   extensions in future. The type can be directly coerced into OsPath.
   -

   *streamly-text* package provides coercion from the Text type to streamly
   Array type and vice-versa.
   -

   *streamly-fsevents* package provides file system event watch streams
   (fsnotify) =E2=80=94 portable as well as full support for low level OS s=
pecific
   file system event APIs. This was earlier part of the streamly package, n=
ow
   has been split into a separate package.

We=E2=80=99ve made every effort to prevent breaking changes, and the API ha=
s
remained stable since version 0.9.0.
