Habitat 0.74.0 Release Notes

We are happy to announce the release of Habitat v0.74.0. We have a number of new features as well as bug fixes, so please read on for all the details. We have a small behavioral change for Windows users when building packages, for more details read on! If you just want the binaries, head on over to Install Habitat.

Thanks again for using Habitat!

Highlights:

Windows Build Change: Set results folder in current directory

One change to the Windows build system in 0.74.0 changes the location of the results folder where the final hart file is saved upon a successful build. Until 0.74.0, the results folder would always exist under the folder where the plan.ps1 file is located. We have changed this location so that the results folder is created inside the current working directory. Thus the results folder will exist in the same directory from wherever you call build if you are inside of a Studio or from where you call hab pkg build.

The reason for this change is that this aligns the Powershell build behavior with the Bash based behavior for plan.sh based plans. We make an effort to align these behaviors in order to simplify the overall behavior of any Habitat build and align expectations and documentation around the Habitat build system in general. The particular detail of the results folder location came to light as we have been working on adding Windows builder workers to our public Habitat CI offering.

If you have built CI infrastructure around Windows based Habitat builds, this change may impact you if you invoke a build from a location above the immediate folder where your plan.ps1 is located. If you typically run build from the same directory where the plan.ps1 is located, this change should have no affect.

A new install hook

A new and unique hook has been introduced in this release that runs when a package is installed. Head over to the Introducting the Install Hook blog post for more details.
