Migration from Deviation 3.0 to 5.0

I've been a long-time Deviation 3.0 user with thousands of trouble-free flights on a Devo 8. The release of 5.0 has me wondering if I should finally upgrade. I fly helis and with DSMX. Outside of telemetry, are there other compelling changes in control algorithms, etc? I've been very impressed with the stability of 3.0 - not one glitch or problem since 2013.

Would Deviation 3.0 models be compatible with 5.0? Can I directly upgrade from 3.0 to 5.0?

Apologies if these questions have been already addressed.

Thanks for your reply. Have there been any significant changes or improvements to the control/mixing algorithms? In other words, any changes that I'd feel at the "stick" level when flying the heli?

Don't move to release 5.0.0 directly, but a more recent build: www.deviationtx.com/forum/builds/6407-de...ith-latest-protocols

5.0 has still heli code + new template bug, you manually need to fix: www.deviationtx.com/forum/6-general-disc...eased?start=60#53953
