 ## [Unreleased]

-## [0.6.1] - 2023-05-17
-### Added
- Error boundaries around each layer, and errors now display on the page when in development
- Utility for creating requirement based on whether a conversion has met a requirement
-### Changed 
- **BREAKING** Formulas/requirements refactor
-    - spendResources renamed to cumulativeCost
-    - summedPurchases renamed to directSum
-    - calculateMaxAffordable now takes optional 'maxBulkAmount' parameter
-    - cost requirements now pass cumulativeCost, maxBulkAmount, and directSum to calculateMaxAffordable
-    - Non-integrable and non-invertible formulas will now work in more situations
-    - Repeatable.maximize is removed
-    - Challenge.maximize is removed
- Formulas have better typing information now
- Integrate functions now log errors if the variable input is not integrable
- Cyclical proxies now throw errors
- createFormulaPreview is now a JSX function
- Tree nodes are not automatically capitalized anymore
- upgrade.canPurchase now returns false if the upgrade is already bought
- TPS display is simplified and more performant now
-### Fixed
- Actions could not be constructed
- Progress bar on actions was misaligned
- Many different issues the Board features (and many changes/improvements)
- Calculating max affordable could sometimes infinite loop
- Non-integrable formulas could cause errors in cost requirements
- estimateTime would not show "never" when production is 0
- isInvertible and isIntegrable now properly handle nested formulas
- Repeatables' amount display would show the literal text "joinJSX"
- Repeatables would not buy max properly
- Reset buttons were showing wrong "currentAt" vs "nextAt"
- Step-wise formulas not updating their value correctly
- Bonus amount decorator now checks for `amount` property in the post construct callback
-### Documentation
- Various typos fixed and a few sections made more thorough
-
 ## [0.6.0] - 2023-04-20
