3.33.0 (2023-07-14)
- Add an option
keepUnusedImportsthat disables all automatic import/export elision, equivalent to the TypeScript optionverbatimModuleSyntax. ([#811], [#615]) (Kotaro Chikuba, Alan Pierce) - Add support for the
await usingproposal and the updated import attributes proposal. Both are preserved in the output code, not transformed. ([#798]) - Fix some issues with TypeScript automatic export elision in
export {...} fromstatements. ([#806])- Type names from the current file are no longer removed.
- When all exports are type exports, the entire statement is now removed.
- Fix bug where
fn(x < y, x >= y)was incorrectly parsed as type arguments. ([#798]) - Fix a few bugs in
enableLegacyBabel5ModuleInterop: properly handleas default, and properly ignore type exports. ([#804], [#807]) (三咲智子 Kevin Deng, Alan Pierce) - Fix bug where parameters inside function types could be misinterpreted as declarations and result in imports being incorrectly marked as unused. ([#809])
- Fix bug where
import {}andexport {}statements were removed with the TypeScript transform disabled. ([#810]) - Make the transform behavior more forgiving when code accidentally has a return type annotation on a constructor. ([#800])

3.32.0 (2023-04-08)
- Improve source map quality by adding column information. This fixes several
source map use cases, such as Jest inline snapshots, source map composition,
and some debugger features. ([#759]) (Emily Marigold Klassen)
- Unfortunately, this change comes at some performance cost. Previously, the slowdown from enabling source maps was about 10%, and now it is about 30%. In most cases, the more detailed source maps are probably still preferable, so for configuration simplicity, there is currently no option to switch back to source maps without column information. If you would like to still use the faster but less accurate implementation, feel free to file an issue to request a new config option, or create the source map yourself in wrapper code by copying the original simple implementation.

published 3.31.0 • Changelog
3.31.0 (2023-03-26)
- Add option to recognize and preserve JSX syntax. ([#788])
- Fix default export interop behavior when using transpiled dynamic
import()to import a plain CJS module. For example, iffoo.jshasmodule.exports = 1;, thenawait import('foo.js')will now evaluate to{default: 1}rather than just1. Named exports behave the same as before. This change matches the behavior of Node.js and other transpilers, so it is considered a bug fix rather than breaking. If you relied on the old behavior, feel free to file an issue and it may be possible to roll back until the next semver-major release. ([#789], [#790])

using. ([#785]) - Decorator after export keyword:
export @foo class .... ([#786])
- Import reflection:
- Fix parsing of
<<within a type. ([#769])
