Please use `v2.4.2` instead. 2025-7-7 ### Bug Fixes - 🐞 Fix `lib/extension.d.ts` missing issue, but failed. Please use `v2.4.2` instead. ## 2.4.0 > ⚠️ This version has a critical issue, please use `v2.4.2` instead. 2025-7-6 ### Features - 🛠 Support `Node.js ESM` - 🛠 Remove file circular dependencies ## 2.3.5 2025-7-6 ### Features - 🛠 Downgrade the requirement of TypeScript to `v3.8` ## 2.3.4 2025-7-2 ### Features - ✨ Enhance the type definitions for methods like `Enum.label`, `Enum.key`, and `Enum.raw` to ensure return types more accurately correspond to input values. When an input value can be matched within the enum, the return type will no longer include `undefined`. ## 2.3.3 2025-6-19 ### Features - 🔥 Allow naming Enum types, accept both plain text and localization keys, similar to the localization for enum members. - 🛠 Mark Enum collection fields as `readonly`. - 🛠 Improve the type of `Enum.label`、`Enum.key`、`Enum.raw` parameters, to accept the real value types. ## 2.3.2 2025-6-10 ### Features - ✨ Improve type IntelliSense for array initialization Enums, allowing enum items to be listed as literals. Thanks to @mudoo. ## 2.3.1 2025-6-7 ### Features - ✨ Add `IEnum` to packages exports ## 2.3.0 2025-5-23 ### Features - ✨ Export new symbols `ENUM_ITEM`，`ENUM_ITEMS` and `ENUM_COLLECTION` which are used to access some special internal properties. - ✨ Add `[ENUM_COLLECTION]: true` to the `Enum` class, which is used to indicates that this is as an enum collection. - ✨ Add `[ENUM_ITEM]: true` to the `EnumItem` class, which is used to indicates that this is as an enum item. - ✨ Add `[ENUM_ITEMS]: true` to `Enum.items` array, which is used to indicates that this is as an enum items array. ### Notable Changes - 💣 Remove `[Symbol.toStringTag]: "EnumItem"` from `EnumItem` class. The result of `Object.prototype.toString.call(enumItem)` is changed from `[object EnumItem]` back to `[object Object]`. If you are relying on this, please use `enumItem[ENUM_ITEM] === true` instead. - 💣 Remove `[Symbol.toStringTag]: "EnumCollection"` from `Enum` class. The result of `Object.prototype.toString.call(enum)` is changed from `[object EnumCollection]` to `[object Array]`. If you are relying on this, please use `enum[ENUM_COLLECTION] === true` instead. ## 2.2.11 2025-5-15 ### Features - 🛠 Remove `"type": "commonjs"` from package.json, which may breaks webpack bundling. ## 2.2.10 2025-5-14 ### Features - ✨ Enhance the type inference of the `raw` method. When the input value matches a specific enum item, it only returns the raw object of that enum item instead of returning the raw objects of all enum items. ## 2.2.9 2025-4-20 ### Features - 🛠 Emit a warning while trying to modify an `EnumItem` ### Bug Fixes - 🐞 the output `lib` directory structure is incorrect. This will break legacy Node.js applications using the `CommonJS` module spec, while modern Node.js applications using the `NodeNext` module spec remain unaffected. This issue was introduced in `v2.2.7`. For node.js applications, it's strongly recommended to upgrade. ## 2.2.8 2025-3-30 ### Bug Fixes - 🐞 Fix `exports` configuration for moduleResolution `ESNext` ## 2.2.7 2025-3-30 ### Features - 🛠 provide different versions of ESModule output for modern browsers and legacy browsers ## 2.2.6 2025-3-29 ### Features - 🛠 change compile transformer - 👀 support `ES2020` and `Chrome>=80`, if you need to support legacy browsers, please use use a modern bundler like `webpack` or `vite` and use `babel` to include proper polyfills on-demand. - 👀 for the Node.js environment, backward compatible down to ES2016. - 🛠 generate better sourcemaps - 🛠 package size reduces by 0.1k ## 2.2.5 2025-3-7 ### Features - 🛠 improve Enum typing, support `boolean` and `Date` as enum values ## 2.2.4 2025-2-24 ### Features - 🛠 Support global type extension for enum localization keys, providing better editor intelligence awareness ## 2.2.3 2025-2-19 ### Features - 🛠 `Enum.localize` supports delayed assignment, i.e. sets the function after the enum is created ## 2.2.2 2025-2-10 ### Features - 🛠 Change the return type of `Enum.options.getKey` - 📖 Update docs ## 2.2.1 2025-2-10 - 📖 Update docs ## 2.2.0 2025-2-9 ### Features - 🔥 Support initializing Enum with native enums - 🔥 Add `items` array, deprecated the _`values`_ array.
