3.2.0.0 Herbert Valerio Riedel <hvr@gnu.org> April 2020
	* `v2-build` (and other `v2-`prefixed commands) now accept the
	  `--benchmark-option(s)` flags, which pass options to benchmark executables
	  (analogous to how `--test-option(s)` works). (#6209)

	  any conflicts encountered in the last version, controlled by flag
	  '--fine-grained-conflicts'. (#5918)
	* `cabal v2-exec` doesn't fail in clean package (#6479)
	* Show full ABI hash for installed packages in solver log (#5892)
	* Create incoming directory even for empty packages (#4130)
	* Start GHCi with `main-is` module in scope (#6311)
	* Implement `--benchmark-options` for `v2-bench` (#6224)
	* Fix store-dir in ghc env files generated by `cabal install --lib
	  --package-env` (#6298)
	* `cabal v2-run` works with `.lhs` files (#6134)
	* `subdir` in source-repository-package accepts multiple entries (#5472)
