There seems to be no debian8 bindist which is different from every
release at least back to ghc-8.0.1.

 Hello everyone,

 The GHC team is pleased to announce the second and likely last alpha
 release of GHC 8.8.1. The source distribution, binary distributions, and
 documentation are available at

     https://downloads.haskell.org/~ghc/8.8.1-alpha2

 A draft of the release notes is also available [1].

 This release is the culmination of over 3000 commits by over one hundred
 contributors and has several new features and numerous bug fixes
 relative to GHC 8.6:

  * Profiling now works correctly on 64-bit Windows (although still may
    be problematic on 32-bit Windows due to platform limitations; see
    #15934)

  * A new code layout algorithm for amd64's native code generator

  * The introduction of a late lambda-lifting pass which may reduce
    allocations significantly for some programs.

  * Further work on Trees That Grow, enabling improved code re-use of the
    Haskell AST in tooling

  * More locations where users can write `forall` (GHC Proposal #0007)

  * Further work on the Hadrian build system

 This release brings a number of fixes since alpha 1:

  * A number of linker fixes (#16779, #16784)

  * The process, binary, Cabal, time, terminfo libraries have all been
    bumped to their final release versions

  * A regression rendering TemplateHaskell unusable in cross-compiled
    configurations has been fixed (#16331)

  * A regression causing compiler panics on compilation of some programs
    has been fixed (#16449)

  * -Wmissing-home-modules now handles hs-boot files correctly (#16551)

  * A regression causing some programs to fail at runtime has been fixed
    (#16066)

 Due to on-going work on our release and testing infrastructure this
 cycle is proceeding at a pace significantly slower than expected.
 However, we anticipate that this investment will allow us to release a
 more reliable, easier-to-install compiler on the planned six-month
 release cadence in the future.

 As always, if anything looks amiss do let us know.

 Happy compiling!

 Cheers,

 - Ben
