+- trackResetTime is now intended to be used with a reset button
+- regularFormat handles small numbers better
+- Slider tooltips now appear below the slider, not above
+- Node's mutation observers now ignore attributes. This shouldn't have issues with links/particle effect positions, but prevents a _lot_ of unnecessary node updates

+- Layers' style and classes attributes are now applied to the tab element rather than the layer-tab
+- Saving now always uses lz-string, and saveEncoding has been renamed to exportEncoding
+    - The property will now only affect exports, and defaults to base64 so exports can be shared in more places without issues
+- Buyables can now have their onClick/purchase function overwritten
+### Fixed
+- Arrays in player were not being wrapped in proxies for things like NaN detection
+- Error when switching between saves with different layers
+- Links would sometimes error from trying to use nodes that were removed earlier that frame
+- createModifierSection would require modifiers to have revert and enabled properties despite not using them
+- Tab buttons would not use the style property if it was a ref
+- Typings on the Board vue component were incorrect
+- Offline time would always show, if offlineLimit is set to 0
+- Buyables will now call onPurchase() when cost and/or resource were not set
+- Presets dropdown wouldn't deselect the option after creating the save
+### Documented
+- feature.ts
+
+## [0.4.0] - 2022-05-01
+### Added
+- Saves can now be encoded in two new options: plaintext and lz compressed, determined by a new "saveEncoding" property in projInfo
+    - Saves will be loaded in whatever format is detected. The setting only applies when writing saves
+- createModifierSection has new parameter to override the label used for the base value
+- createCollapsibleModifierSections utility function to display `createModifierSection`s in collapsible forms

+- Saves manager would not clear the current save from its cache when switching saves, leading to progress loss if flipping between saves
+- Layer.minWidth being ignored
+- Separators between tabs (player.tabs) would not extend to the bottom of the screen when scrolling
+- Tree nodes not being clicked on their edges
+### Changed
+- **BREAKING** No features extend persistent anymore
+    - This will break ALL existing saves that aren't manually dealt with in fixOldSave
+    - Affected features: Achievement, Buyable, Grid, Infobox, Milestone, TabFamily, and Upgrade
+    - Affected features will now have a property within them where the persistent ref is stored. This means new persistent refs can now be safely added to these features
+- Features with option functions with 0 required properties now don't require passing in an options function
+- Improved the look of the goBack and minimize buttons (and made them more consistent with each other)
+- Newly created saves are immediately switched to
+- TooltipDirection and Direction have been merged into one enum
+- Made layers shallow reactive, so it works better with dynamic layers
+- Modifier functions all have more explicit types now
+- Scaling functions take computables instead of processed computables
+### Removed
+- Unused tsParticles.d.ts file
+### Documented
+- modifiers.ts
+- conversions.ts
+
+## [0.3.3] - 2022-04-24
+### Fixed
+- Spacing between rows in Tree components
+- Computed style attributes on tooltips were ignored
+- Tooltips could cause infinite loops due to cyclical dependencies
+
+## [0.3.2] - 2022-04-23

+- createLayerTreeNode wasn't using display option correctly
+
+## [0.3.1] - 2022-04-23
+### Added
+- Render utility methods that always return JSX Elements
+### Changed
+- **BREAKING** Tooltips overhaul
+    - Tree Nodes no longer have tooltips related properties
+    - Tooltips can now be added to any feature with a Vue component using the `addTooltip` function
+    - Any tooltip can be made pinnable by setting pinnable to true in the addTooltip options, or by passing a `Ref<boolean>` to a Tooltip component
+    - Pinned tooltips have an icon to represent that. It can be disabled by setting the theme's `showPin` property to false
+- Modifiers are now their own features rather than a part of conversions
+    - Including utilities to display the current state of all the modifiers
+- TabFamilies' options function is now optional
+- Layer.minWidth can take string values
+    - If parseable into a number, it'll have "px" appended. Otherwise it'll be un-processed
+- TreeNodes now have Vue components attached to them
+- `createResourceTooltip` now shows the resource name
+- Made classic and aqua theme's `feature-foreground` color dark rather than light
+
+## [0.3.0] - 2022-04-10
+### Added
+- conversion.currentAt [#4](https://github.com/profectus-engine/Profectus/pull/4)
+- OptionsFunc utility type, improving type inferencing in feature types
+- minimumGain property to ResetButton, defaulting to 1
+### Changed
+- **BREAKING** Major persistence rework
+    - Removed makePersistent
+    - Removed old Persistent, and renamed PersistentRef to Persistent
+    - createLazyProxy now takes optional base object (replacing use cases for makePersistent)
+    - Added warnings when creating refs outside a layer
+    - Added warnings when persistent refs aren't included in their layer object
+- **BREAKING** createLayer now takes id as the first param, rather than inside the option function
+- resetButton now shows "Req:" instead of "Next:" when conversion.buyMax is false
+- Conversion nextAt and currentAt now cap at 0 after reverting modifier
+### Fixed
+- Independent conversion gain calculation [#4](https://github.com/profectus-engine/Profectus/pull/4)
+- Persistence issue when loading layer dynamically
+- resetButton's gain and requirement display being incorrect when conversion.buyMax is false
+- Independent conversions with buyMax false capping incorrectly
+
+## [0.2.2] - 2022-04-01
+Unironically posting an update on April Fool's Day ;)
+### Changed
+- **BREAKING** Replaced tsparticles with pixi-emitter. Different options, and behaves differently.

+### Changed
+- **BREAKING** Reworked most of the code from Links into a generic Context component that manages the positions of features in the DOM
+- Updated vue-cli and TS dependencies
+- Challenges cannot be started when maxed, and `canStart` now defaults to `true`
+- onClick listeners on various features now get passed a MouseEvent or TouchEvent when possible
+- Minor style changes to Milestones, most notably removing min-height
+### Fixed
+- Buyables didn't support CoercableComponents for displays
+- TreeNodes would have a double glow effect on hover
+### Removed
+- Unused mousemove listener attached to App.vue
+
+## [0.1.4] - 2022-03-13
+### Added
+- You can now access this.on() from within a createLayer function (and other BaseLayer properties)
+- Support for passing non-persistent refs to createResource
+- dontMerge class to allow features to ignore mergeAdjacent
+### Fixed
+- Clickables would not merge adjacent
+- onClick and onHold functions would not be bound to their object when being called
+- Refs passed to a components style prop would be ignored
+- Fixed z-index issue when stopping hovering over features with .can class
