idleoneerAccount DataPatch Notes
Every update
Newest first. Each version is the day the update came out, with .1, .2 and so on for later updates that day.
2026.11.03
- Small fixes behind the scenes.
2026.11.02.3
- Legend Talents opens for accounts with the Obsidian artifact at Verisimilitude, instead of saying the save can't be read. Obsidian adds 6 Legend Talent PTS at Verisimilitude, as at Transcendent, since the game counts no more than 6.
2026.11.02.2
- A plan's Cape Vine step also marks the last slot and lists the cape that ends up there when a swap into a Golden Vine changes your last cape, so you can see which cape's base stats the Vine will count (Sample Optimizer, Drop Optimizer, Stat Optimizer).
2026.11.02.1
- Where a plan changes the last cape on your Cape Vine, its step now says which cape to drop on the last slot and marks that slot, as it does the Golden Vines. The Vine counts only its last cape's base stats (Sample Optimizer, Drop Optimizer, Stat Optimizer).
2026.11.02
- The Cape Vine step in the plans of the Sample Optimizer, the Drop Optimizer and the Stat Optimizer draws your Vine as the game hangs it, with gold ropes for your Golden Vines, each cape numbered as the steps name its slot, and the slots the plan changes marked.
2026.11.01.2
- The site follows IdleOn v1.25, the Cape Vine update.
- The Cape Vine has pages of its own under World 4. Vine draws Cathie's Vine as the game hangs it, with what each cape gives in its slot, and shows your Golden Vines and the class level the next one needs.
- Cape Vine Bonuses lists every bonus the Vine adds, which characters get it, and its base stats, which come from the last cape on the Vine alone. A cape outside a Golden Vine gives a quarter of its bonuses, as the game counts it, not the 20% the patch notes say.
- Golden Vines shows where your Golden Vines come from, which character can ask Cathie for the next, and what each cape gives in one, with the swap that adds the most to a bonus you pick.
- Missing Capes lists the capes your Vine doesn't have, where each one is, and ranks them by what each would add.
- Every page that works out a character's stats counts the Cape Vine, such as the Stat Optimizer and Weekly Battle. A character that has reached World 4 gets the Vine's capes instead of the cape it wears.
- The Drop Optimizer, the Stat Optimizer and the 3D Printer's Sample Optimizer can move capes into your Golden Vines and add capes to the Vine, such as putting the Lovely Balloon in a Golden Vine for drop rate. They no longer suggest a cape to wear for a character that has reached World 4.
- Max Damage counts Research's Eclectoplasmaticism, which adds damage for each green sigil, up to +100% (Stat Optimizer, Weekly Battle).
- Extra Bones and Extra Dust on the Prisma page and in the Stat Optimizer count Killroy's masterclass drops bonus in full, as v1.25 fixed it.
- Spelunking Speed and Efficiency on the Prisma page count Pit O' Pages from your best character, so every account gets at least +30% Spelunking Speed.
- The 3D Printer's output multiplier includes the Legend Talent Yet Another Printer Multi (Output, Printer).
- The Slab lists v1.25's 1,938 items, adding the Lovely Balloon cape and the Funny 2hr Feather and Funny 2hr Slice, and counts the Feather and Slice among the items storage can green-stack.
- The Rift's Skill Mastery page lists Research's seven rewards and the Total Family LV each starts at, and writes totals of 10,000 or more in thousands.
- Research EXP, grid points and the lowest and highest observation rolls count the Rift's Research Skill Mastery on the Grid and Observations pages, and the Observations page breaks down your lowest roll.
- The Research Optimizer counts each Skill Mastery rank your Research levels reach on the way to your target, and says at which level. Routes saved before this update are cleared.
2026.11.01.1
- Jelly Operator's Upgrades page lists the best next upgrades by the damage or income each adds for its cost, whether or not you can afford them yet, and says how many more Bloodcells each needs. A Show menu lists the next 5, 10, 25 or 50.
2026.11.01
- The Prisma page has a Hide Prisma bubbles checkbox next to the character picker, which leaves your Prisma bubbles out of the ranking and the unranked lists so you see only the ones left to make Prisma. The Prisma multiplier now sits on one line beside its label.
2026.10.31.1
- A new Prisma page under Alchemy ranks your levelled bubbles by how much making each one a Prisma bubble would raise a character's totals, the ones already Prisma included. It counts where the game caps a total, such as crit chance past 100% or a trap's shiny chance, and ranks efficiency bubbles by the AFK resources they'd add at the hardest node the character can harvest.
2026.10.31
- The Jade an hour at the top of the Sneaking and Jade Emporium pages has an info button that opens a panel listing every source of your Jade. Multipliers that work alone are listed apart from the bonuses that add together before they multiply, such as your vial, meal and card, each with what it gives now. A table of the sneaking twins shows each one's floor's Jade, Currency Conduit, charms, belts and Gold Envelope, its actions an hour and the Jade it finds.
2026.10.30.2
- Jelly Operator's Upgrades page shows what each Stronkroid level really adds. Cells attack on whole frames, so a level only speeds up the cells it saves a frame: many levels add nothing, and others add several times what the page used to show. It also counts when you use Stronkroid and the Immuno Weakening its extra Amoeba hits add.
- The Doublers page values Stronkroid's doubler the same way, and Cell Layout and the Optimizer weigh Stronkroid this way when they pick which boards to test in battles.
2026.10.30.1
- The 3D Printer's Sample Optimizer, the Drop Optimizer and the Stat Optimizer now tell you to top up a gold food stack the character already has on when a bigger stack raises the result. Each stack is filled to the character's food carry capacity, with the prayer swap that raises it while you take the food out.
2026.10.30
- A new Stat Optimizer, under Tools, takes any stat the site works out, such as Drop Rate, Class EXP or Max Damage, a character and one of its talent presets, and finds what to change in every system for the most of that stat, step by step, with what the account lacks that would raise it more.
- The Drop Optimizer and the 3D Printer's Sample Optimizer have a Preset pick beside the character too, and plan on the talent preset you pick instead of switching presets on their own. Each optimizer remembers your pick for every character. Until you pick, the Stat and Drop Optimizers plan on the preset the character has on, and the Sample Optimizer on the one with Printer Sampling.
2026.10.28.2
- Better usage stats behind the scenes.
2026.10.28.1
- Jelly Operator's Optimizer plans routes with about a third of the memory it used, so it's far less likely to stop partway through on a large account. Cell Layout's layout searches use less memory too.
2026.10.28
- A page your browser reopens from a visit before September 30 opens without an error.
2026.10.27.2
- Better error reports behind the scenes.
2026.10.27.1
- A new Drop Optimizer, under Tools, takes any item a monster drops, a character, and whether it fights AFK or actively, and finds where to fight and what to change in every system for the most of it, an hour AFK or a kill active. It counts every drop table, the cards and stamps you've found, your Loot Filter and the obols World 2's merit adds.
2026.10.27
- Small fixes behind the scenes.
2026.10.26.1
- Meritocracy's Ballot shows its three lines side by side, each with its vote share and bar.
2026.10.26
- New pages for the Slab in World 5. Items shows every item the Slab lists, found or missing, as a grid or a list, with the items Magma Rivertown adds on your next visit, the missing items your characters hold or wear, your green stacks and the items you haven't green-stacked yet. Bonuses shows the eight Slab bonuses, what opens each, what each step adds and how many more items the next step takes.
- New pages for Sneaking in World 6. Floors draws the Ninja Castle floor by floor with each twin's Stealth, chance to be detected, and the Jade, EXP and door damage it brings in an hour. Gear shows the inventory and each twin's hat, weapon and charms. Knowledge lists Ninja Knowledge with its costs and when your Jade covers each. Gemstones shows each gemstone's bonus and collection. Charms shows the Pristine Charms you've collected and their bonuses.
- A new Beanstalk page in World 6 draws the beanstalk in Spirit Village with each golden food's stacks, its bonus now and at its next stack, what opens the bigger stacks, and how much of each food you hold.
- A new Jade Emporium page lists its upgrades in the Emporium's order, each bought, or with its cost and when your Jade covers it.
- A new Emperor page shows his wins, HP and your attempts, when the next reset adds more, and each of his 12 bonuses with the showdown that raises it next.
- Added a link to the Idleoneer Discord.
- The Mainframe board is shorter: the explanations above and below it are gone.
- The Lab's Console shows each character's chip slots straight on the page, under the Chip Slots heading, and its columns stretch to fill the page's width. The chips are larger.
- The note under the clouds on Equinox's Dreams page is gone.
- Jelly Operator's Doublers page no longer warns that the endgame build has changed since its board was searched.
- Jelly Operator's Cell Layout and Optimizer just say when to use Stronkroid, such as "Use Stronkroid at 21.3 seconds.", without its attack speed and how long it lasts.
2026.10.24.6
- Small fixes behind the scenes.
2026.10.24.5
- Jelly Operator's Optimizer tries the unlocks you can afford, such as a new fever, cell or board region, even when damage upgrades alone could clear the obstruction. It used to skip them then, so it could recommend damage upgrades when Rabies, for example, clears more often for about the same Bloodcells. Planning takes longer in that case, because each of those unlocks gets its own layout searches.
- Optimizer routes made before this update are cleared, so plan them again.
2026.10.24.4
- Large numbers the site works out, such as simulated damage and Bloodcells per attempt, use the game's units: Q for quadrillions and QQ for quintillions, where they read Qa and Qi, and then e notation, such as 3.46e22, as the game writes them.
2026.10.24.3
- Jelly Operator's Cell Layout and Optimizer say when to use Stronkroid in real seconds, so you can time it with a clock. Their times used to follow the operation's timer, which runs faster than a clock, so a Stronkroid timed with one came late. Stronkroid lasts 4.9 seconds, where they said 8.2.
- Every other operation time is in real seconds too: clear and revival times, the damage chart, and the operation timer, which reads 18 seconds for the first obstruction where it read 30, on Cell Layout, Doublers and Obstructions.
- Cell Layout and the Optimizer play operations at the game's speed: projectiles take as long to land as they do in the game, Cold adds 1% damage each real second, and your best DPS is measured over real seconds, as the game's DPS display measures it. Their damage, clears and Bloodcells come closer to the game's, and Cold no longer grows faster than it does in the game.
- A cell's DPS on the board is per real second, as the game counts DPS.
- Optimizer routes and the Doublers endgame build made before this update are cleared, so plan them again.
2026.10.24.2
- Jelly Operator's Optimizer plays Sepsis on operations that can't clear the obstruction, where it used to keep Rabies, Plague or Cold, and times Stronkroid for it. On the same board that often earns nearly twice the Bloodcells. Clears that also succeed with Sepsis use it too.
2026.10.24.1
- When the site updates while you have it open, the next page you open loads the update, so you get the latest fixes without reloading. It waits while a search is running.
- A search whose files didn't load tries once more before it asks you to reload the page.
2026.10.24
- Small fixes behind the scenes.
2026.10.23.2
- The 3D Printer's Sample Optimizer now raises talents past their max level with books from the Talent Book Library, up to the highest level your account's books reach. Its talent points and super talents are planned with those levels, and a Talent Books step lists each talent to book first.
2026.10.23.1
- Small fixes behind the scenes.
2026.10.23
- The Research Grid no longer plans where to spend your grid points. The Optimizer still plans them along its route to the level you pick.
- The level number over each observation level-up in Research's Optimizer shows the right digits again.
- Every hat on the Hat Rack shows its own sprite on its peg again, the Halloween hats included.
- The sidebar's worlds and pages are more compact, so more of them fit on screen.
2026.10.22.6
- Research's Optimizer counts the observation rolls you have left today. Once they run out, the rest of today's finds wait for the daily reset, and the route plans until then with what you've found.
- Each find before the daily reset tells you to come back and recalculate the route if its roll misses.
2026.10.22.5
- When two updates go live minutes apart, the site no longer goes back to the older one.
2026.10.22.4
- Steam login no longer turns away the address from Idleon's Steam page.
- Pasting a Steam address that has expired or was already used now says so, and asks you to sign in on Steam again.
2026.10.22.3
- Small fixes behind the scenes.
2026.10.22.2
- Jelly Operator calls each fever by its in-game name: Cold, Rash, Sepsis, Nausea, Rabies and Plague.
2026.10.22.1
- Pages load their styles, fonts and images ahead of their scripts, so they appear sooner.
2026.10.22
- Idleoneer has a home page, with every system it covers and these patch notes. Each update to the site now has a version, named for the day it comes out, and the version under the navigation opens every update's notes.
- The calculations follow IdleOn v1.24, the Halloween Event update, with its twelve new Event Shop items.
- Minehead is out. Its Doublers page shows what a Luminous Menagerie doubler adds on each upgrade it can go on, and Upgrades lists the next levels to buy, in order.
- Jelly Operator's Doublers page plans where the Menagerie's Jelly doublers go, judged on an endgame build of your account.
- Killroy's Schedule forecasts the rooms of this week and the 51 after it.
- Breeding, Cooking, the Lab and the Rift are out, as is the Luminous Menagerie's Jellyfish page.
- The 3D Printer's Sample Optimizer now plans super talents, meal ranks, the attack bar's moves and the Gallery's trophies, takes items and obols from any character, and no longer recommends prayers that add nothing.
- On a phone, the menu opens a system's pages.
