2.0.0

• All fps and resolution constraints are now added to the optional section of the video constraints as this is now being respected in latest Chrome (plus the use of them in optional, causes failure with capture instead of graceful fallback - which is rarely the default desired behaviour).
• In addition to generating the currently supported minWidth, minHeight, maxWidth, etc, etc constraints we are also supporting the new width: { min: x, max: y } format, as outlined in draft-alvestrand-constraints-resolution-03
