Questions about this release? Ask in the official discussion thread: #​1666

Added

• Adds workaround for extensionless entrypoints with ESM loader (#​1649, #​1654)
  • You can now combine tools such as mocha with --loader ts-node/esm, where previously node would throw [ERR_UNKNOWN_FILE_EXTENSION]
  • node has a bug where combining --loader with an extensionless entrypoint causes this error nodejs/node#​33226
  • Some tools, for example mocha, have an extensionless entrypoint. (source, source)
  • Combining NODE_OPTIONS=--loader ts-node/esm with these tools causes this error. mochajs/mocha#​4645
  • node intends to fix this bug in a future release: nodejs/node#​41711
  • In the interim, we have implemented a workaround in ts-node.
• Adds support for target "ES2022" in moduleTypes overrides (#​1650)

Fixed

• Fixed bug where --swc and other third-party transpilers did not respect moduleTypes overrides (#​1651, #​1652, #​1660)
• Fixed bug where node flags were not preserved correctly in process.execArgv (#​1657, #​1658)
  • This affected child_process.fork(), since it uses process.execArgv to create a similar child runtime.
  • With this fix, child_process.fork() will preserve both node flags and ts-node hooks.
• Fixed compatibility TypeScript 4.7's API changes (#​1647, #​1648)
