Was a bit surprised not being able to find the changelog for 0.5.6.5 with the change log for this version being 0.5.6.6 so since I couldn't find any info on it I'll just add it here.
Changelog for 0.5.6.5.
- Updated combat system with new combat animations for the MC
- Yasmine & Liandra bonus scene + scene with Giron&Liandra & transformation option at camp
- New BJ scene with Kate at the inn inside the MC's room when you go there with Kate in the evening
- Reworked dialogue images for: Marcus, MC, Thomas, Corven
- Reworked the hunting images + added a small animation to it
- Fixed some images on Emily's kidnapp event
- Reworked some of the intro images (not completely done with that)
- The Lucius Potion quest has been changed a little to make the intro more fluid (Making it easier for new players)
- Balanced out quest xp depending on level. (if you still find quest rewards where you get multiple levelups please let me know! I will probably have missed some)
- Smaller bugfixes and changes (I can't remember them all)
Liandra part from what I could understand if you keep her at the bandit camp and she watches the MC dance with Lyvia + pull up her shirt + Tia dancing naked 5 times. Liandra will wish for a bigger bust, the MC then get's the option to tell her she's fine with a small bust or go on a small quest to get her a bigger bust, no quest log on it so read what it tells you to do.
There is also a 3some - The MC must have had sex with Yasmine on her bed at least once, if Liandra is in town talk to her and she will go to Giron's study (if you've not prevented her bust increase there will now be a new scene with Giron it differs depending on if she's wearing a chasity belt or not), then talk to her in the evening and there is a chance of the 3some triggering, might take a few days. If Liandra is in camp then the raven quest must have been completed and the MC has had sex with Liandra + Yasmine then talk to Yasmine in the living room to trigger it.
So yeah there wasn't much new stuff in the update outside of some scenes mostly but well 0.5.7.0 will probably be out soonish hopefully so the walkthrough will explain it all.
