Option to keep the feed up to date with the latest version.
When adding packages or in the packages list I should be able to select either a specific version or a static value of 'latest' which will resolve to the most recent version no matter when I ask for the MyGet feed.
This way today when I run my chocolatey cinst all command I get whatever version is currently setup. When I install a new dev machine 6 months from now and I run my chocolatey install I should end up with the latest versions.
Although we don't expose this (yet) in our UI as such, you can accomplish this today by adding package sources to your feed (see feed settings), and apply an OData filter on it (e.g. fixed to a specific package ID). If you check the box to embed the query in your feed results, the updated package will always be picked up going forward as soon as it changes on the underlaying package source.
