Now that version 4.6 is out the beta resets. There are features that are hidden in the release version but are visible in the beta so they can be tested and refined.
Live on the edge, follow the beta. It is fairly stable, but transient problems do pop up. They are quickly dealt with and the beta is occasionally updated daily. If you are running the beta you will be notified if a new version is available.
Existing Features in the Beta
Units conversions for the standard numerical column type.
Create them through the gear menu.
A preference option so that you can set when the Points command switches to a pixel approach.
The default is 200,000 but you can raise it if you want to get more points drawn with the selected marker.
Scalar Field command - recently added an option to draw logically rectangular meshes.
This means you can specify the x and y coordinates of the mesh as arrays and not just lists.
Column - Number From String - Looking for a good use case
Database & JSON file connectivity
