Firmware 7.3.1.7

In our experience, the entire 7.x.x.x line of firmwares is buggy and unstable. 7.1.1.7 is even worse than 7.3.1.7. We had massive problems with STP and L3 routing with the 7.x.x.x firmwares. Furthermore, the 7.x.x.x firmwares are vulnerable to multiple remote DOS attacks that leave you with a hard-locked switch that requires a power cycle to get it going again. Yes, it is definitely worth the upgrade. Just make sure you follow the instructions Netgear supplies.

Upgraded to 8.*, had a big issue with switches as they didn't take older config and decided to go into infinite rebooting loop. I manually removed config - that worked so I just copy-pasted everything back in and that was it... There was no problem upgrading switch from 7.1->7.2->7.3 though.
