Since nobody mentioned that explicitly: do not upgrade to 9.6. If you upgrade, move to v13.
Not sure I'd suggest people upgrade to v13. If they are in a position to do so and accept the risk involved with a first year point release great, but I wouldn't make that assumption when making a blind suggestion. v12 would be the best from an efficiency/risk perspective at this moment in time, IMO. v9.6 is only being supported for one more year would be the reason to avoid choosing it.
