Okay. But I would question the wisdom of having the lion's share of updates for sentinel being closed source until the last minute when you guys say it is "ready". Let me know if there's somewhere else I should be looking
Sentinel is not closed-source. Here is the original:
https://github.com/evan82/sentinel
I am working every day on it: https://github.com/nmarley/sentinel/tree/required-changes
There are a couple others working on different change sets:
https://github.com/tgflynn/sentinel
https://github.com/kefkius/sentinel
Work is being done every single day in the background, and it's open on Github if you want to take a look. Most of us work on the weekends too. The git logs are open for all to see.
