Currently, there is no guide that I am aware of, but here are the notes past 0.23, available under the downloads section:
(TL;DR: 2 bathhouse scenes: Thane and Axel, new character: Frode, multiple events, and some stat adjustments)
-0.24a: New character Frode was added, and after meeting him you may see him in Jorgen's bar to unlock the pray dialogue for him, Witer, and Ebb (A new marker is added to the bull mountain between the bridge and snowy mountain entrance with a statue, offering a Labrador Tea and praying with Witer's style grants a consumable giving -5 COR, obtainable once). After returning to the tavern, you may ask Axel (or Nauxus if lizard route) to clean the temple. A new scene is added (Entering the demon city without any corruption now allows the player to bribe their way in).
-0.25e: After helping Frode with some ingredients, you can trigger a scene the next time you visit Einar's home. After helping Parif with making 5 dishes, you may trigger an event, there are rare events with Bread after he joins the Tavern, which become more common after returning from the snowy mountains. You may visit the bathhouse and invite Axel to unlock a new scene (Bull ending + Sex option only).
-0.26c: New location on the map: Campsite (Always available in neutral route, only available on lizard route if you helped them with setting it up, not available on bull route, but Axel will give a reward instead). New event: Chet's Big Plan (available at the Campsite, offering lvl up points and 500 gold per item, up to 6 items + 1 if neutral route). After returning from the mountains, Witer will leave towards the blocked exit, speaking to him will bring him back. If Bread is in the tavern, visiting the bathhouse will sometimes trigger a new scene. You may invite Thane to the bathhouse (neutral ending).
-0.27d: A strange slime can be found at the first slime zone after returning from the snowy mountains (Unlocks 3 scenes depending on slime size, which increases with each "feeding"). Certain stats have been adjusted (Str from +3 to +5 atk, Agi from +1 to +2 atk)
