Habitat 0.79.0 Escaped Defect

We have found a bug in the recent 0.79.0 release that prevents a Supervisor in a local Windows studio from successfully invoking hooks. Note that this only occurs in a local studio and likely only in a clean install where c:\hab\pkgs\core\powershell\ does not exist. This should not affect a Docker studio or a production Supervisor running in a Windows service.

If you have installed the 0.79.0 release on Windows and find that you are unable to launch services inside of a local studio, the best way to work around this issue is to install the core/powershell package outside of the studio. To do this, make sure that you have exited the studio and then run hab pkg install core/powershell.

We will be releasing a 0.79.1 release to fix this issue shortly.
