Dear all,

we have just started the code freeze for dash.js version 4.4.0.

Again big thanks to all the contributors.

We would like to ask you for some help testing this release. We greatly appreciate your help to verify it is free from regression. Any help, feedback, comment will be really appreciated.

Due to major changes in the code base of dash.js we will have an extended testing period. Release date of version 4.4.0 will be May 4th. You can find all the issues and pull requests of the 4.4.0 milestone here. The release candidate can be found here.
