Recent updates
3.0.0
7/19/2023Version 3.0.0 modernizes estree-util-is-identifier-name to use Unicode property escape regular expressions and to validate identifiers based on Unicode code points rather than UTF-16 code units. It also introduces optional JSX identifier support and switches the package to an explicit ESM exports entrypoint. The release is marked as a major change, including a Node.js 16 requirement.
BreakingFeatures2.1.0
1/19/2023Release 2.1.0 updates the identifier character set generation to Unicode 15, along with some repository maintenance (docs/code-style refactors and tsconfig changes). The code diff also shows a small internal refactor that moves generated regex code under a new lib/ directory and updates build/test tooling.
Features2.0.1
6/12/2022Release 2.0.1 is primarily a documentation and project-metadata update, alongside enabling TypeScript strict mode. The release notes also mention migrating the repository under the syntax-tree org.
1.1.0
3/12/2021Release 1.1.0 primarily adds JSDoc annotations intended to drive TypeScript declaration generation. The code changes are small, but the project’s packaging and build pipeline were expanded to generate and ship *.d.ts files during build and prepack.
Features2.0.0
3/12/2021Release 2.0.0 migrates the package to ESM. The release notes only state “Use ESM”, but the code diff shows the module format and public export shape changed, which affects how consumers import the library.
