So I saw 5.076 is out, so I'm going to give a rather neutral report on my new 5.075 game. The main thing I wanted to do was try out Starfleet Commander with the new starships and rebalanced starships and see if everything was working as intended. Short answer: Yes, but I didn't get far in three hours of play.
Map setup: 100 Stars, Simple Clusters, Stealth Battleship as bonus. 7.3/7.3 Gravity Drill/Starfleet Commander, (Advanced) Hybrid Hives on both, Astrotrains on both, Normal+Champion, various minor factions set mostly on easypion
The map generation seems fine. However, cluster is turning out a LOT more difficult than I expected. There are two Interplanetary Munitions Boosters in my corner of the galaxy. They're far out enough (at least 3 hops) that in a normal game, they'd be of no concern. Between the gravity drills, hive, and occasional Eye, I've a lot less room to go around than usual, and hunting hybrids is a nastier proposition than usual.
Incoming waves are fine... minirams, stealth battleships, that sort of thing. Oddly, I'm getting 3 starships from each wave, I had expected 4 from the tooltip - I presume it's a budget thing.
Where things are becoming really, really scary for me are the new and improved reinforcement mechanics. I have to plan a little bit more when there are 90 snipers in a gravity drill system and there may or may not be IPMB boosting it. In otherwords, bring the silly scouting starships already.
Ultimately, it isn't going too well, on account of my not being properly prepared. Three and half hours in, 3 systems. I spent way too much time on the Champion earlier when I should have probably been focusing all my attention on planning and executing a plan of attack . I did a lot of neutering, but time in the nebula counteracted that.
Ignoring everything up above, I wanted to see how starfleet commander handled with the new ship changes. Nothing broken, nothing particularly unusual, I saw Zenith Starships, Spire Starships, everything as expected except for seeing only three starships at a time. I'm debating with myself whether I want to see the AI show a little more focus on incoming starships. The leeches and bombards and everything are dangerous enough, but if around half the time it picked one type (or two if was sending six or more) it might end up a lot scarier (if it wasn't for the leech starship change I wouldn't even consider suggesting this).
In this timeframe due to my slow expansion, I didn't have any opportunity to reflect on higher unlocks, but I'm going to aim for more Heavy Bomber Starships if I can break out of my self-imposed trap. If I can't, I'll start over on a new seed with the new patch, aiming for less IPMB. I really don't want to turn hives down, but I simply might not be able to multi-task well enough with normal expansion, hive hunting, champion championing.
P.S.
Next time I should try special forces commander plus gravity drills. It might be a little weird.
