v3.0.0

Compare Source

Tailwind CSS v4 is here and it's time to upgrade tailwind-merge to support it. tailwind-merge v3.0.0 is more accurate than ever and follows the Tailwind CSS spec more closely than in v2. That is thanks to Tailwind CSS v4 being more consistent than ever.

This release drops support for Tailwind CSS v3 and in turn adds support for Tailwind CSS v4. That means you should upgrade to Tailwind CSS v4 and tailwind-merge v3 together. All breaking changes are related to the Tailwind CSS v4 support.

Check out the migration guide and if you have any questions, feel free to create an issue.

Breaking Changes
  • Dropping support for Tailwind CSS v3 in favor of support for Tailwind CSS v4 by @​dcastil in #​518
  • Theme scales keys changed and now match Tailwind CSS v4 theme variable namespace exactly by @​dcastil in #​518
  • isLength validator was removed and split into separate validators isNumber and isFraction by @​dcastil in #​518
  • Prefix defined in config shouldn't include combining - character anymore by @​dcastil in #​518
  • Tailwind CSS v3 prefix position in class not supported anymore in favor of Tailwind CSS v4 position by @​dcastil in #​518
  • Custom separators are no longer supported by @​dcastil in #​518
  • New mandatory orderSensitiveModifiers property in config when using createTailwindMerge by @​dcastil in #​518
  • DefaultThemeGroupIds type union consists of different string literals than before by @​dcastil in #​518
  • Classes removed in Tailwind CSS v4 are not supported by tailwind-merge anymore by @​dcastil in #​518
New Features
  • Support for new important modifier position at the end of class by @​dcastil in #​518
  • Support for arbitrary CSS variable syntax by @​dcastil in #​518
  • There are a bunch of new validators used by tailwind-merge, primarily for new Tailwind CSS v4 features like arbitrary CSS variables by @​dcastil in #​518
Bug Fixes
  • Previously some order-sensitive modifiers like before: were treated as not order-sensitive. This is now fixed by @​dcastil in #​518

v2.4.0

Compare Source

New Features
  • Allow hooking into class parsing logic (experimental) by @​dcastil in #​444
    • There is no info to this in the docs because this is experimental, but there is a new experimentalParseClassName property in the config that allows you to customize how tailwind-merge recognizes classes. If you're interested, you can read how to use it in the inline JSDocs and subscribe to #​385 for upcoming more powerful low-level functionality.
  • Create security policy by @​dcastil in #​439
    • Added documentation on how to report potential vulnerabilities
  • Avoid @babel/runtime dependency by @​dcastil in #​431
    • Now no dependencies in tailwind-merge anymore. This dependency was only used in the tailwind-merge/es5 bundle anyway which I don't optimize for.

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 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 and if you have any questions, feel free to create an issue.

Breaking Changes
  • Fix background-image and background-position being merged incorrectly by @​dcastil in #​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 for tailwind-merge. If you use background position or background size with arbitrary values, please read this section about how to use them.
  • Make types of available keys more strict and configurable through generics by @​kachkaev in #​279
  • Make it possible to override elements with extendTailwindMerge by @​dcastil in #​294
  • Separate validators better by @​dcastil in #​292
  • Make conflictingClassGroupModifiers in config non-optional by @​dcastil in #​291
  • Move separator to config by @​dcastil in #​290
  • Remove module field from package.json by @​dcastil in #​289
  • Remove deprecated exports by @​dcastil in #​288
  • Transpile lib to more modern JS by @​dcastil in #​287

  • Explain limitations of arbitrary values in bg-size and bg-position class groups in docs by @​dcastil in #​328

Thanks to @​quezlatch, @​brandonmcconnell, @​manavm1990 and @​ErwinAI for sponsoring tailwind-merge! ❤️

v1.14.0

Compare Source

New Features
  • Improve support for arbitrary values by @​dcastil in #​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
    • 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.

  • Add npm package provenance by @​dcastil in #​219

v1.12.0

Compare Source

With this release tailwind-merge supports all features introduced in Tailwind CSS v3.3.

New Features
  • Add support for postfix modifier by @​dcastil in #​214
    • This adds support for line-height modifiers in font-size utilities like text-lg/7 and more potential postfix modifiers in the future (learn more).
    • All classes are checked for postfix modifiers since there will be more in the future and they'll be configurable with plugins.
    • tailwind-merge can't know from the class syntax alone whether something is a modifier or not. E.g. there is w-1/2 which doesn't contain a modifier. So tailwind-merge always checks whether class without potential modifier exists and if it doesn't it checks for full class. This behavior might get reversed in the next major version as a breaking change (learn more).
    • Added conflictingClassGroupModifiers object to tailwind-merge config (learn more).

Full Changelog: dcastil/tailwind-merge@v1.11.0...v1.12.0

v1.11.0

Compare Source

New Features
  • Add support for Tailwind CSS v3.3 except line-height shorthand by @​dcastil in #​210
    • The line-height shorthand in font-size utilities (text-lg/7) introduced in Tailwind CSS v3.3 is not yet supported in tailwind-merge because that feature is a bit more involved. I'll add support for it in a future release. More info in #​211.
    • Added new validator isPercent which is needed internally for the default scale of color stop positions.
    • New theme key gradientColorStopPositions supported in tailwind-merge.
    • New logical properties like ps-0 (padding-inline-start: 0px;) are de-duplicated away when using the matching property for all sides afterwards like in this case p-0, but not when using single axis sides like px-0 because padding-inline-start can also be the top or bottom padding depending on writing mode.
      • Basically twMerge('ps-0 p-0') === 'p-0' && twMerge('ps-0 px-0') === 'ps-0 px-0'.
      • If you want to use logical properties and know which writing modes your app is limited to, add the right conflicts yourself to your tailwind-merge config.
