- Update to version 1.9.1:
* On May 16th 2023, HCP introduced multi-project support to the
platform. In order to use multiple projects in your
organization, you will need to update Packer to version 1.9.1
or above. Starting with 1.9.1, you may specify a project ID to
push builds to with the HCP_PROJECT_ID environment variable. If
no project ID is specified, Packer will pick the project with
the oldest creation date. Older versions of Packer are
incompatible with multi-project support on HCP, and builds will
fail for HCP organizations with multiple projects on versions
before 1.9.1.
