The tailwind-merge v2 release has been sitting here almost finished for 2 months already. But the timing was never quite right, especially thinking about the increased support needed after the release. In the meantime, the product of the company I work at [launched in public beta](https://medium.com/risecal/meet-rise-the-calendar-that-works-for-you-were-launching-the-public-beta-today-bc07555a2191) and I married. Thank you for your patience.

This release focuses on making it easier to configure the library for new users. Check out the [migration guide](https://github.com/dcastil/tailwind-merge/blob/v2.0.0/docs/changelog/v1-to-v2-migration.md) and if you have any questions, feel free to [create an issue](https://github.com/dcastil/tailwind-merge/issues/new/choose).

Breaking Changes

- Fix `background-image` and `background-position` being merged incorrectly by dcastil in https://github.com/dcastil/tailwind-merge/pull/300
- Values for `background-position` and `background-size` can look very similar and Tailwind CSS uses the same `bg-` prefix for both groups. This results in some [limitations](https://github.com/dcastil/tailwind-merge/blob/v2.0.0/docs/limitations.md) for tailwind-merge. If you use background position or background size with arbitrary values, please read [this section](https://github.com/dcastil/tailwind-merge/blob/v2.0.0/docs/limitations.md#you-need-to-use-label-in-arbitrary-background-position-and-background-size-classes) about how to use them.

New Features

- Improve support for arbitrary values by dcastil in https://github.com/dcastil/tailwind-merge/pull/263
- Previously, tailwind-merge checked the content of the arbitrary value portion of a class in most cases to understand whether the type of the arbitrary value is correct (e.g. it checked for number followed by length unit for the length type). That lead to the issue that a class like `mt-[calc(theme(fontSize.4xl)/1.125)]` would not be recognized correctly because no length unit is present in the arbitrary value.
- I changed the check of the arbitrary value to also pass when a `calc()`, `min()`, `max()` and `clamp()` function is used in the arbitrary value.
- In ambiguous cases, you can use data type labels to mark the type of a class. [Read more](https://github.com/dcastil/tailwind-merge/blob/v1.14.0/docs/features.md#supports-arbitrary-values)
- Moreover, I removed the check where the type of the arbitrary value is unambiguous. In the class `mt-[…]` the arbitrary value can only be a length, so I don't check for it. A consequence of this is that if you use non-Tailwind classes like `mt-[this-is-totally-not-tailwind]`, tailwind-merge will recognize it as a Tailwind class from now on. **Please don't use classes that look like Tailwind classes with arbitrary value but aren't Tailwind classes with tailwind-merge (in default config) to prevent incorrect merging behavior**.

Bug Fixes

- Fix `col-span-full` class missing in default config by dcastil in https://github.com/dcastil/tailwind-merge/pull/267
- Fix arbitrary value with no present length unit not being recognized by dcastil in https://github.com/dcastil/tailwind-merge/pull/263

Documentation

- Add missing info about where to call config functions to docs by dcastil in https://github.com/dcastil/tailwind-merge/pull/264
