  • 27.0.2

    7 months ago

    Release 27.0.2 is primarily described as an npm publish fix to ensure prior fixes from 27.0.1 are properly published. The code diff shows changes focused on the CI publish workflow and small internal version bumps for the monorepo packages.

  • 27.0.1

    8 months ago

    Release 27.0.1 focuses on restoring browser compatibility for ts-morph packaging. It adjusts the package.json "browser" export mapping so bundlers correctly treat additional Node built-ins as unavailable in browser builds.
