This is a preliminary, WIP roadmap/plan for what we on the @PowerShell/powershell-committee believe needs to be in a PowerShell 6.0 release. We will be iterating on this significantly based on your feedback, as well as potentially shifting internal priorities. The goal is for all line items here to eventually be represented by issues attached to either the 6.0.0 or 6.0.0-beta milestones, so that you anyone can look in and see how far along we are towards a 6.0 release.

I also plan on publishing a blog to break down our plans in more detail sometime soon. In the meantime, please join us on the PowerShell Core Community Call tomorrow @ 9am PST where we'll be talking about this in more detail.

If you believe we're missing something here that's absolutely critical for the 6.0 release, please let us know below in the comments or on our monthly Community Call. Thanks!
