This is a bug-fix release. Bug fixes: * 1.6.1 introduced a change that made some precompiled cache files use longer paths, sometimes causing builds to fail on windows. This has been fixed. See [#3649](https://github.com/commercialhaskell/stack/issues/3649) * Some unnecessary rebuilds when no files were changed are now avoided, by having a separate build cache for each component of a package. See [#3732](https://github.com/commercialhaskell/stack/issues/3732). * Correct the behavior of promoting a package from snapshot to local package. This would get triggered when version bounds conflicted in a snapshot, which could be triggered via Hackage revisions for old packages. This also should allow custom snapshots to define conflicting versions of packages without issue. See [Stackage issue #3185](https://github.com/fpco/stackage/issues/3185). * When promoting packages from snapshot to local, we were occassionally discarding the actual package location content and instead defaulting to pulling the package from the index. We now correctly retain this information. Note that if you were affected by this bug, you will likely need to delete the binary build cache associated with the relevant custom snapshot. See [#3714](https://github.com/commercialhaskell/stack/issues/3714). * `--no-rerun-tests` has been fixed. Previously, after running a test we were forgetting to record the result, which meant that all tests always ran even if they had already passed before. See [#3770](https://github.com/commercialhaskell/stack/pull/3770). * Includes a patched version of `hackage-security` which fixes both some issues around asynchronous exception handling, and moves from directory locking to file locking, making the update mechanism resilient against SIGKILL and machine failure. See [hackage-security #187](https://github.com/haskell/hackage-security/issues/187) and [#3073](https://github.com/commercialhaskell/stack/issues/3073).
