Banana’s October 31 2025 patch lands on Steam with a clear seasonal tilt and a handful of systems changes that will affect how players manage stacks and trade up items. The headline here is the new exchange system that uses explicit success and fail percentages for trade-ups, plus a new ability to mix collections; there are also UI tweaks, a Halloween theme, and a 60,000 per-stack limit to keep the Steamworks short integer from misbehaving.
We previously covered Banana’s Latest Update Fixes Achievement Issues and Teases New Skins and this patch continues the steady cadence of fixes and minor features from the developer.
Patch Notes – 31-10-2025
- Theme/UI
- Added a new theme for halloween
- Added a new background music for halloween
- Updated every UI to match the halloween theme
- Added tooltips for every button with a description of what it does, so people can learn what each thing does
- Well Of The Past
- Updated the full scene UI for a spooky vibe
- Inventory
- Adds a new system that automatically fixes everyone’s stacks if they exceed 60k quantity
- Developer Note: Since the Steamworks SDK only allows a “short” integer value for the quantity variable, we had unstack the items automatically to prevent some items of having negative values or overall wrong values
- Fixes visualization on some bananas & items that would sometimes show a negative value
- “Show on market” button now opens within the Steam Overlay
- Adds a new system that automatically fixes everyone’s stacks if they exceed 60k quantity
- Inventory/Stacking
- Adds a limit of stacking items to 60 000 per stack. If a user has any item quantity that exceeds this value (more closer to 65 000) some quantities might appear wrong, so a restart in the game should fix it.
- Inventory/Exchange
- Updates the exchange system to utilize a % fail rate as follows:
- Normal -> Common = 75% Success rate & 25% fail rate
- Common -> Uncommon = 80% Success rate & 20% fail rate
- Uncommon -> Rare = 85% Success rate & 15% fail rate
- Rare -> Epic = 90% Success rate & 10% fail rate
- Epic -> Ultra Rare = 95% Success rate & 5% fail rate
- Ultra Rare -> Legendary = 100% Success rate
- Adds a new ability of using and mixing collections!!
- Note: Only bananas that drop can be traded up with other bananas that also drop. You cannot trade up dropped bananas with capsule bananas.
- Updates the exchange system to utilize a % fail rate as follows:
- Drop Timer
- Fixes an issue that caused the drop timer to reset and stay in loop checking every 3 minutes after a person just got a drop.
- Menu’s
- Added the ability to press “ESC” button to go back in the menu’s or to close them, to make it easier and faster to move around.
- Menu/Drop Pool
- Fixes an issue where the drop pool list would duplicate
- Fixes an issue where the drop pool list would not reopen after closing
- Banners
- Feedback button now opens within the Steam Overlay
- Item shop button now opens within the Steam Overlay
- Settings
- Workshop button now opens within the Steam Overlay
- Hidden / For future releases
- Adds a new Login Streaks feature (disabled in production)
- Adds a new Item Shop panel in-game (hidden for now)
– The Banana Team
If you manage items in bulk, the stacking cap and Steamworks explanation are the real practical changes here; the exchange percentages and the collection mixing add a layer of predictability to trade-ups while still keeping some risk. The Halloween UI and music are the cherry on top, if that sort of thing matters to you.
