Nope, it's various bug fixes: https://forums.frontier.co.uk/showthread.php/393882-Update-2-4-09
I'm still unsure what Elite's lack of Dash support will really mean. It seems like we'll still be able to pin windows in the game. The beta is apparently out right now, someone test it!
Edit: apparently that was just internet rumor, nevermind. I'm hoping Dash will be up and running tonight when I get home from work.
App Compatibility
In some legacy apps, when you press the Oculus button, Dash will not come up as an overlay inside of the app, but will instead open in its own environment. All other Dash functionality will be available. We recently introduced tools so developers can integrate full Dash support and our list of fully Dash-compatible apps is growing.
