GX/LS Older Firmware Download

I’m trying to upgrade a few GX and LS gateways to the latest firmware. For the LS300 I need firmware 4.3.4 to get to 4.4.0, however I’m unable to find older versions of the firmware on the site. The only option I have is to download 4.4.0

Yep, nevermind found it. Right in front of my face.
