-# 5.0.0
+# Changelog
 
-Ground-up rewrite that migrates to a more composable API. Under the hood, classes were refactored
-into functions to reduce file size and overhead.
-
-#### 💥 Breaking
-
-The biggest change is that predicates are now known as schemas. For the purpose of this release, the
-changelog will use the new verbiage, but may affect previous APIs.
-
-- Updated `array()` to no longer accept a schema as an argument, use `array().of()` instead.
-- Updated `func()` to not be nullable by default. Instead uses `undefined`.
-- Updated `instance()` to no longer accept a schema as an argument, use `instance().of()` instead.
-- Updated `object()` to no longer accept a schema as an argument, use `object().of()` instead.
-- Renamed `Schema#nonNullable()` method to `notNullable()`.
-- Removed `Schema#key()` method.
-- Removed `Schema#message()` method.
-- Removed the `predicate()` predicate (use `schema()` instead).
-- Removed the state boolean argument from `Predicate#required()`.
-- Dropped Node.js v10 support. Minimum requirement v12.17.
-
-#### 🚀 Updates
-
-- Added `Schema#notRequired()` method.
-- Added `date()`, `schema()` schemas.
-- Added `createSchema()` function for creating custom schemas.
-- Added `createPredicate()` function for creating boolean return checkers.
-
-#### 🛠 Internals
-
-- A `ValidationError` is now thrown instead of an `Error`.
-- Migrated to Packemon for package building.
-- Improved the handling of `null` and `undefined` values.
-- Increased code coverage, especially around edge cases.
-- Renamed predicates to schemas.
-- Renamed validation checks to criteria.
-
-### 4.3.0 - 2020-02-20
-
-#### 🚀 Updates
-
-- Improved error messages by including the currently invalid value.
-
-#### 🐞 Fixes
-
-- Fixed an issue where arrays and tuples were used at the same time in a union.
-
-#### 🛠 Internals
-
-- Updated union error messages to be more readable.
-- Updated tuple type aliases to use "tuple<value>".
-
-### 4.2.1 - 2020-02-11
-
-#### 🐞 Fixes
-
-- Fixed some object comparison checks that would fail cross-realm.
-
-## 4.2.0 - 2020-01-26
-
-#### 🚀 Updates
-
-- Reworked default values to handle undefined and null by default, and in a much better fashion.
-
-### 4.1.2 - 2020-01-26
-
-#### 🐞 Fixes
-
-- **[shape]** Reset schema state after validating children.
-- **[array,object,string]** Updated empty checks to take nullable into account.
-
-### 4.1.1 - 2020-01-24
-
-#### 🐞 Fixes
-
-- **[func]** Removed the generic constraint as it is too restrictive.
-
-## 4.1.0 - 2020-01-20
-
-#### 🚀 Updates
-
-- Added `Schema#currentPath`, `currentValue`, `initialStruct`, `parentPath`, and `parentStruct`
-  properties. Should make custom tree checks much easier.
-- Added `Predicate#doRun`, so that sub-classes can hook into the run process.
-
-#### 🐞 Fixes
-
-- **[shape,tuple]** Fixed an issue where common predicate checks were not always running.
-
-### 4.0.1 - 2020-01-19
-
-#### 🐞 Fixes
-
-- **[tuple]** Fixed some array type check failures.
-- **[tuple]** Fixed tuples failing to validate when in a `union`.
-
-# 4.0.0 - 2020-01-07
-
-#### 💥 Breaking
-
-- Updated Node.js requirement to v10.
-- Values are now type cast once all checks and validations have ran. This may cause unexpected
-  results in production, but is not exactly breaking.
-- Updated `custom()` callbacks to receive a `Schema` as the 2nd argument instead of a struct object.
-- Removed and inlined all `check*` methods as we don't want them publicly chainable.
-- Renamed `Builder` to `Predicate` for all classes.
-- Renamed `Builder#runChecks()` method to `Predicate#run()` and reworked the arguments.
-- Renamed `builder()` to `predicate()`.
-- **[ts]** Added visibility modifiers to many internal properties and methods.
-
-#### 🚀 Updates
-
-- Add new `Schema` class for handling the building and validation of structs.
-- Add new `tuple()` predicate .
-- Add support for default values via factory functions.
-- Add `Predicate#default()` to return the default value.
-- Add `Predicate#validate()` to run stand-alone validation with a predicate.
-- **[array,object,string]** Add `sizeOf()` method.
-- **[number]** Add `float()`, `int()`, `negative()`, and `positive()` methods.
-- **[string]** Add `lowerCase()` and `upperCase()` methods.
-
-#### ⚙️ Types
-
-- Updated `object()` and `ObjectOf` to support mapped types through a keys generic.
-
-#### 🛠 Internals
-
-- Package is now built with Rollup to reduce filesize.
-
-## 3.4.0 - 2019-12-28
-
-#### 🚀 Updates
-
-- Add `never()` for all predicates.
-- **[bool]** Add `onlyFalse()` and `onlyTrue()` methods.
-- **[string]** Add `camelCase()`, `kebabCase()`, `pascalCase()`, and `snakeCase()` methods.
-
-#### ⚙️ Types
-
-- Update `CustomCallback` with a struct generic.
-
-#### 📦 Dependencies
-
-- Update to latest.
-
-## 3.3.0 - 2019-12-02
-
-#### ⚙️ Types
-
-- Refined types and replaced `any` with `unknown`.
-
-## 3.2.1 - 2019-04-22
-
-#### 🐞 Fixes
-
-- Fixed some build issues.
-
-## 3.2.0 - 2019-04-20
-
-#### 🚀 Updates
-
-- Added a `prefix` option to `optimal`, which customizes the initial object path prefix for errors.
-- Builder methods can now return a value to mutate the value being checked.
-
-#### 🐞 Fixes
-
-- Shapes within arrays, objects, or unions are now returned with the full object.
-
-#### 🛠 Internals
-
-- Updated `ShapeBuilder` to call `optimal` internally, as the APIs are very similar.
-- Removed `@babel/runtime-corejs3` as it wasn't saving much space.
-
-### 3.1.1 - 2019-04-13
-
-#### 🐞 Fixes
-
-- Updated `StringBuilder#contains` and `StringBuilder#match` to only check when the passed value is
-  not the default value _or_ the field is required.
-
-## 3.1.0 - 2019-04-07
-
-#### 🚀 Updates
-
-- Added `ShapeBuilder#exact`, which throws on unknown fields and requires an exact shape.
-- Updated `UnionBuilder` to support builders of the same type in parallel. For example, can now use
-  2 instances of `object()`.
-- Updated `UnionBuilder` to support object and shapes in parallel.
-- TS: Updated `instance()` to allow abstract classes.
-
-# 3.0.0 - 2019-04-03
-
-#### 🚀 Updates
-
-- Added a `builder()` predicate, which checks that a property value is a `Builder` instance.
-- Added a `blueprint()` predicate, which checks that a property is an object of `Builder`s.
-
-#### 🛠 Internals
-
-- Updated to `@babel/runtime-corejs3`, which uses Babel v7.4 and CoreJS v3.
-- TS: Updated `optimal` to return the shape wrapped in `Required`.
-- TS: Updated `Blueprint` to remove optional properties (acts like `Required`).
-- TS: Updated `Builder#custom` to infer the value argument based on the builder type.
-- TS: Replaced some usage of `any` with `unknown`.
-
-### 2.1.1 - 2019-02-07
-
-#### 🐞 Fixes
-
-- Fixed some inheritance issues for instance of checks in loose mode.
-
-## 2.1.0 - 2019-02-06
-
-#### 🚀 Updates
-
-- Removed docblocks from source files to reduce bundle size.
-
-# 2.0.0 - 2019-01-30
-
-#### 💥 Breaking
-
-- TypeScript minimum version requirement is now 3.0.
-- TypeScript has been rewritten to infer builder types and structures as best it can. This may cause
-  unexpected inferrence for `optimal()` usage and may require explicit generic types to be passed.
-- Nested blueprints must now use `shape()` instead of a plain object.
-- Collections have split into `ArrayBuilder` and `ObjectBuilder`. `array()` and `object()` are still
-  the same.
-- `Builder#nullable` no longer accepts an argument and instead enables nulls.
-- `custom()`
-  - Default value is now required at all times.
-  - TS: Type will be inferred by the default value. Can be explicitly typed using generics.
-- `shape()`
-  - Default value has been removed (since it's inferred by nested blueprint structure).
-- `string()`
-  - String logic has been reversed, as they are now empty by default, instead of not empty. To
-    enable the old logic, use the `notEmpty()` method.
-  - The `empty()` method has been removed.
-- `union()`
-  - Default value is now required at all times.
-  - TS: Type is `any` as unions are not inferrable. Can be explicitly typed using generics.
-
-#### 🚀 Updates
-
-- Added documentation.
-- Added a `file` option to `optimal()` to include in error messages.
-- Added a `predicates` export from the index, which is an object of all builder factory functions.
-  - TS: Also added a `Predicates` type representing this shape.
-- Added a `loose` option to `instance()`, so cross-realm instance checks work (compares constructor
-  name).
-- Added `Builder#notNullable` to disable null values.
-- Added `StringBuilder#notEmpty` to require strings to not be empty.
-
-#### 🛠 Internals
-
-- TS: Removed `Struct` type.
