New Features

- Fix missing arbitrary value support in some class groups by dcastil in https://github.com/dcastil/tailwind-merge/pull/73
- Adds arbitrary value support for class groups `grayscale`, `invert`, `sepia`, `grow`, `shrink`, `object-position`, `shadow`, `drop-shadow`, `rotate`, `skew` and `transform-origin`
- Fixes `break-inside` classes being merged incorrectly
- Adds missing classes `overline`, `underline-offset`, `content-none`

- I changed the build output significantly here and removed `"type": "module"` from the package.json. I did test the new npm package output in Node and in the browser, but it's hard to account for every possible build system tailwind-merge is used in. If some issues come up with bundling tailwind-merge, please open an issue!

v1! 🎉

Overview

After being 5 months on v0 I think it's time to release a stable version of tailwind-merge. Tailwind v3 was [released](https://github.com/tailwindlabs/tailwindcss/releases/tag/v3.0.0) yesterday and it's no coincidence that I'm releasing tailwind-merge v1 today. I added full support for Tailwind v3 so you can update both at once.

There are no breaking changes in the tailwind-merge types and some breaking changes for a small number of users in the return values, so you should get through smoothly.

By the way, you can now [sponsor](https://github.com/sponsors/dcastil) this project. 😊

Breaking Changes

- `twMerge`, `extendTailwindMerge`
- Outline utilities from Tailwind v2 don't get merged anymore since they were replaced by outline width, outline style, outline offset and outline color in Tailwind v3 (https://github.com/dcastil/tailwind-merge/pull/63/commits/55ab167b7167519873c5dd4d258dc62212d1659a, https://github.com/dcastil/tailwind-merge/pull/63)
- The classes `overflow-ellipsis` and `overflow-clip` will not get merged with class `truncate` anymore, but the new Tailwind v3 classes `text-ellipsis` and `text-clip` will. (https://github.com/dcastil/tailwind-merge/pull/63/commits/65b03e48914ac5d7d52eea9ec178b204d30609c9, https://github.com/dcastil/tailwind-merge/pull/63)
- The classes `decoration-slice` and `decoration-clone` won't get merged anymore and `box-decoration-slide` nad `box-decoration-clone` will (https://github.com/dcastil/tailwind-merge/pull/63/commits/bfe2cc9bb221107fa0bf363cc325ddbb04677f43, https://github.com/dcastil/tailwind-merge/pull/63)

- `getDefaultConfig`
- Removed class group `outline` since it was removed in Tailwind v3 (https://github.com/dcastil/tailwind-merge/pull/63/commits/55ab167b7167519873c5dd4d258dc62212d1659a, https://github.com/dcastil/tailwind-merge/pull/63)
- Renamed class group `vertival-alignment` (yes, the typo was in the code) to `vertical-align` (https://github.com/dcastil/tailwind-merge/pull/63/commits/1269ce68ae39807ceadbecc98c0929fdfdb446d0, https://github.com/dcastil/tailwind-merge/pull/63)
- Renamed class groups `flex-basis`, `flex-grow` and `flex-shrink` to `basis`, `grow` and `shrink` to stay consistent with Tailwind v3 (https://github.com/dcastil/tailwind-merge/pull/63/commits/e6d8912e47bf9a89346b9b0cc822fb2bff2af172, https://github.com/dcastil/tailwind-merge/pull/63)

- `validators`
- `isCustomLength` and `isCustomValue` were renamed to `isArbitraryLength` and `isArbitraryValue` to be consistent with naming in Tailwind v3 documentation (https://github.com/dcastil/tailwind-merge/pull/63/commits/adc3c02c7f035069beec1c62777ec008172587ab, https://github.com/dcastil/tailwind-merge/pull/63)
