Source and binary distributions are available at the usual place: https://downloads.haskell.org/ghc/8.10.1-alpha1/ GHC 8.10.1 will bring a number of new features including: * The new UnliftedNewtypes extension allowing newtypes around unlifted types. * The new StandaloneKindSignatures extension allows users to give top-level kind signatures to type, type family, and class declarations. * A new warning, -Wderiving-defaults, to draw attention to ambiguous deriving clauses * A number of improvements in code generation, including changes * A new GHCi command, :instances, for listing the class instances available for a type. * An upgraded Windows toolchain lifting the MAX_PATH limitation * Improved support profiling, including support for sending profiler samples to the eventlog, allowing correlation between the profile and other program events This release marks the beginning of the 8.10 pre-release cycle. The next alpha release will be in roughly two weeks. This next alpha will likely be the last release before the release candidate in late December. If all goes well the final release will be cut roughly two weeks after the candidate, in mid-January. This being an alpha release, there are a few issues that are still outstanding: * The new Alpine Linux binary distribution is not present due to an apparent correctness issue [1]; any help Alpine users can offer here would be greatly appreciated. * We have yet to sort out compliance with Apple's notarization requirements [2] which will be likely be necessary for users of macOS Catalina. * There is an issue with the users guide build that has yet to be sorted out. * There are a couple of non-regression correctness issues which we plan to fix for the final 8.10.1 but are not fixed in this release. * Debian 10 builds are not yet available. Please do test this release and let us know if you encounter any other issues.
