Dear all, Last week I tagged Cabal-3.4 release candidate. After fixing few immediately obvious issues with cabal-install, I have successfully used it for a week. This week I have been working on improving scripts for bootstrapping and release packaging, and as intermediate result there are - x86_64-darwin-sierra - x86_64-ubuntu-14.04 - x86_64-alpine-3.11.6 - amd64-freebsd-12.1-RELEASE - aarch64-ubuntu-18.04 bootstrapped builds at https://oleg.fi/cabal-install-3.4.0.0-rc1-bootstrapped/ The ubuntu-14.04 build works on later ubuntu, debian, and centos which I tried (in docker). Note, alpine build is not static, i.e. it dynamically links against musl. Please try these out, especially try to build cabal-install (from 3.4) branch, and use it, so we can fix most of regressions since 3.2. I'm specially interested whether the darwin/macos build works on newer macos versions. The release notes for Cabal-3.4 and cabal-install-3.4 are available at https://github.com/haskell/cabal/tree/master/release-notes - Oleg
