IMPROVEMENTS:

• builder/docker: Now supports Download so it can be used with the file provisioner to download a file from a container. [GH-2585]
• builder/docker: Now verifies that the artifact will be used before the build starts, unless the discard option is specified. This prevent failures after the build completes. [GH-2626]
• post-processor/artifice: Now supports glob-like syntax for filenames. [GH-2619]
• post-processor/vagrant: Like the compress post-processor, vagrant now uses a parallel gzip algorithm to compress vagrant boxes. [GH-2590]

BUG FIXES:

• core: When iso_url is a local file and the checksum is invalid, the local file will no longer be deleted. [GH-2603]
• builder/parallels: Fix interpolation in parallels_tools_guest_path [GH-2543]

FEATURES:

• [Beta] Artifice post-processor: Override packer artifacts during post- processing. This allows you to extract artifacts from a packer builder and use them with other post-processors like compress, docker, and Atlas.
