Add 'latest' option on Octo.exe -package overrides
When using Octo.exe's --packageversion to specify a version for all packages, and then --package to override one package, it would be helpful if --package would let you specify 'latest'.
--packageversion 6 --package SomeSinglePackage:latest
Currently if a script is sending --package SomeSinglePackage:2 and there is a new version, you have to remember to change the script to version 3.
This scenario occurs when you are trying to release a specific version of your application, but one package is shared across many projects and won't have the same version number as the project being deployed.
