v1.8.0

New Features

• Add support for custom separator by @dcastil in #168
• Add support for dynamic viewport units in arbitrary lengths by @dcastil in #166
• Rename join to twJoin by @dcastil in #161
  • I deprecated the join function and renamed it to twJoin to make replacing it via search and replace easier since join is a common function name. You don't need to change anything right now, but if you have some spare time, rename join → twJoin in your code since the join function will be removed in the next major release.

v1.7.0

New Features

• Add support for Tailwind CSS v3.2 by @dcastil and @brandonmcconnell in #159

Full Changelog: v1.6.2...v1.7.0

v1.6.2

Bug Fixes

• Fix arbitrary numbers not working in stroke-width by @dcastil in #153
  • Now tailwind-merge handles classes like stroke-[3] correctly.
  • I deprecated the validator isArbitraryWeight and renamed it to isArbitraryNumber to reflect its broader use case. You don't need to change anything right now, but if you have some spare time, rename isArbitraryWeight → isArbitraryNumber in your code since isArbitraryWeight will be removed in the next major release.

Other

• Add package version number to dev releases by @dcastil in #154
  • Now dev releases don't start with 0.0.0-dev anymore and instead have the version number of the last release, like 1.6.1-dev. That makes it easier for tools like Renovate to understand which package version you're using in case you use dev releases.

v1.6.0

New Features

• Add support for arrays as argument by @dcastil in #127
  • You can now use arbitrarily nested arrays as arguments to twMerge. That's especially handy for nested conditions.

    twMerge('…', someBool && ['…', anotherBool && '…'])

  • The joining of arguments is done with a new join function which is present in the tailwind-merge exports as well. It has the same functionality as clsx but without support for objects as arguments which makes it a little faster.
  • Why no objects as arguments? You can read about my reasoning in https://github.com/dcastil/tailwind-merge/discussions/137#discussioncomment-3481605.

Bug Fixes

• Replace matchAll with exec by @dcastil in #133
  • This makes tailwind-merge work in older browsers which don't support String.prototype.matchAll()

Other

• Add recipes section to docs by @dcastil in #134
• Split docs into multiple files by @dcastil in #131
• Add comments to released PRs and their related issues by @dcastil in #130

• Remove ts files from npm package by @dcastil in #128
