 ### Added
+- Watchlist - use the UI to quickly add a term (username, IP, command, etc.) that MozDef alerts on
+- Generic Deadman - use a simple config file to validate that expected events are appearing in a given time window (and alert an Error when they do not)
 
 ### Changed
+- Improve error handling on Slack bot
+- Improve Slack bot alert format for better readibility
+- Minor UI adjustments
 
 ### Fixed

+- Added checks on sending SQS messages to only accept intra-account messages
+- Improved docker performance and disk space requirements
