Written guide is here.
Yes, not patched for 0.6 yet- it will be done! Probably after It's release on Itch.io because it might spoil and confuse users that still have the old version.
On the devlog there's enough information for you to try and figure out if you've got everything. It lists the ammount of unique CG's and added content - It just doesn't guide you. Hopefully this helps you! Here it is:

What Open said. This will (probably) be updated a few days after the game releases here on Itch; I don't want to spoil anyone before-hand. Meanwhile, feel free to ask on SubStar if you can't find a scene (you know how many there are, so just compare that to what you've seen). On that note, I should clarify that "scene" can be confusing here. I use it to mean "a set of CG that all have the same base, with minor variations," rather than the movie definition of "a chunk of action that happens." So for example the stuff that happens in the host club is one "scene" by my terms, even though in movie terms it's three.
You need to have lost at least once for Mezz to agree to enter the Host Club - maybe that's what you're missing? Take a look at what Mezz says when you try to enter Host Club.
That "side alley" message is in the new version as well - It probably refers to the fact that the two available paths right now are in "side alleys" - since there will be another expansion adding a center path later on.
When you wake up in Mahir's office and he tells you he needs you to deal with Khazeem for him, he tells you that you either have to do "work" for him by going to the porn shop or you can fight him instead. If you fight him and win, he'll give you the lucky charm. If you equip it, you can't get hypno'd by the hyena mobs and it makes the fights easier.
