I would like to point out a simple point.

 

Where there is compatibility break (like replace the dll doesn't anymore work with the old javascript) the file version should be changed.

 

Today build 4.0.0.0 FileSize: 233,472 bytes

While few weeks ago the same version was 4.0.0.0 and FileSize: 196,608 bytes.

Between both version all javascripts or almost have changed.

 

New API sound very nice, gonna dig into that deeper :-)
