BACKWARDS INCOMPATABILITIES:
* HCL: builder/vsphere: Add option to add a xhci/usb3 controller; changes
controller value to an array of strings. [GH-9574]
* HCL: New HCL-only post-processors block to run chained post-processors
after a build [GH-9638]. Before this, defining multiple post-processor
blocks after provisioning steps would run them sequentially, now doing this
makes them start from the build artifact. To queue post-processors you now
have to define them in a post-processors block. [GH-9638]
* post-processor/vSphere: We have fixed a bug in the ovftool URL
encoding. This may mean that you have performed an encoding workaround that
is no longer necessary. [GH-9589]
