Is there some reason the 2.1 releases don't trigger the package manager to show that an update is available? I've been on 2.0.1 for a very long time, and I just figured development had slowed down. But tonight I noticed the other versions. However, package manager wasn't showing an icon telling me I could upgrade, despite enabling preview packages: Is that by design? Are the 2.1 releases experimental, or flagged in some way to intentionally not prompt for upgrade?
