Hello everyone,<br>
<br>
The GHC team is very pleased to announce the second candidate of the<br>
8.2.1 release of the Glasgow Haskell Compiler. Source and binary<br>
distributions are available at<br>
<br>
<a href="https://downloads.haskell.org/~ghc/8.2.1-rc2/" rel="noreferrer" target="_blank">https://downloads.haskell.org/~ghc/8.2.1-rc2/</a><br>
<br>
This is the second of what will likely be either two or three release<br>
candidates leading up the final 8.2.1 release. This release will<br>
feature,<br>
<br>
* A new type-indexed Typeable implementation<br>
<br>
* The long awaited Backpack<br>
<br>
* Deriving strategies for disambiguating DeriveAnyClass,<br>
GeneralizedNewtypeDeriving, and stock mechanisms<br>
<br>
* Overloaded record fields<br>
<br>
* Improved compiler performance<br>
<br>
* Better code generation through more robust tracking of join points<br>
<br>
* Compact regions for more efficient garbage collection and serialization<br>
<br>
* Better support for machines with non-uniform memory architectures<br>
<br>
* More robust support for levity (e.g. RuntimeRep) polymorphism<br>
<br>
* A simple interface for streaming eventlog data from live processes<br>
<br>
* Further refinement of DWARF support<br>
<br>
This candidate fixes most of the issues present in release candidate<br>
one including,<br>
<br>
* #13233: typePrimRep panic while compiling GHC with profiling enabled<br>
* #13509: type error involving unboxed tuples<br>
* #13426: compile-time memory-usage regression<br>
* #13560: Windows binary distributions carry absolute paths to toolchain<br>
* #13585: Control.Lens.Wrapped.ala causes compiler panic<br>
* #13623: Join points produce bad code for stream fusion<br>
<br>
As always, please let us know if you have difficulty. Thanks to everyone<br>
who has contributed!<br>
<br>
Happy testing,<br>
<br>
- Ben<br>
