Version 3.1e has just a few fixes but one is important to a number of users which explains the release.
Fixed: Mouse wheel use in the edit boxes of grid controls on the edit panes, there should no longer be a loss of focus. It should also now be possible to use the up and down arrows to change values.
Fixed: FBX Import could fail if there were a number of objects in a model.
Fixed: The Fresnel reflection intensity was capped at 5.0 it should now be possible to enter values up to 100.
Fixed: The Import as Objects function was missing the recent folder button.
Fixed: The zoom multiplier has been restored as the zoom multiplier in 3.1d was too slow for some users.
