The GHC development team is pleased to announce the first alpha release<br>
of the 8.4.1 release. The usual release artifacts are available from<br>
<br>
<a href="https://downloads.haskell.org/~ghc/8.4.1-alpha1" rel="noreferrer" target="_blank">https://downloads.haskell.org/~ghc/8.4.1-alpha1</a><br>
<br>
Note that this release drops compatibility with GCC 4.6 and earlier.<br>
While we generally try to place as few constraints on system toolchain<br>
as possible, this release depends upon the __atomic__ builtins provided<br>
by GCC 4.7 and later (see #14244).<br>
<br>
<br>
=== Notes on release scheduling ===<br>
<br>
The 8.4.1 release marks the first release where GHC will be adhering to<br>
its new, higher-cadence release schedule [1]. Under this new scheme,<br>
major releases will be made in 6-month intervals with interstitial minor<br>
releases as necessary.<br>
<br>
In order to minimize the likelihood of schedule slippage and to ensure<br>
adequate testing, each major release will be preceeded by a number of<br>
regular alpha releases. We will begin issuing these releases roughly<br>
three months before the final date of the major release and will issue<br>
roughly one every two weeks during this period. This high release<br>
cadence will allow us to quickly get fixes in to users hands and allow<br>
better feedback on the status of the release.<br>
<br>
GHC 8.4 is slated to be released in mid-February but, due to technical<br>
constraints, we are starting the alpha-release cycle a bit later than<br>
planned under the above schedule. For this reason, it would be greatly<br>
appreciated if users could put this alpha through its paces to make up<br>
for lost time.<br>
<br>
As always, do let us know if you encounter any trouble in the course of<br>
testing. Thanks for your help!<br>
<br>
Cheers,<br>
<br>
- Ben<br>
