# v2.0.6

 - [IMP] devtools: provide access to Fiber and RootFiber
 - Bump shelljs and git-rev-sync
 - [FIX] props validation: do not subscribe to props keys
 - [FIX] reactivity: only show key in subscription if observed by callback
 - [FIX] components: stop rendering stale t-component when delayed
