There were many commits that don't make a lot of sense to anyone but me probably, since they were so massive in scale...especially leading up to this release. For example, moving the configuration from web.config-ish xml style to JSON in preparation for a larger system I wanted to have done before open sourcing it to not hose adopters later.
That being said, most commits are decent size features or several every day or two. This was completely a side-project for me, happening while waiting on something or in the evening. Going forward, we're shifting focus to monitoring and will be giving some real dedicated time to it. We will be building our own monitoring system as a whole, polling, push, agents, etc...and Opserver is a large part of that big picture. Those commits will be much more interesting, and you're going to see them all.
If there are any questions though, I'm happy to answer them...we're pretty wide open, just short of sharing logins and passwords.
