- **[Breaking]** We now use TypeScript's JSX transformer instead of maintaining our own. As a result, `React.createElement` now requires a self parameter, so remove `@noSelf`, `this: void` if necessary.

- **[Breaking(-ish)]** Due to limitations in 5.1, try/catch can no longer be used in async or generator functions when targetting Lua 5.1. This was already broken but now tstl will explicitly give an error if you try.

- Added support for the `switch` statement in all versions! (Before they were not supported in 5.1 and universal).

- Added support for `string.prototype.replaceAll` and improved `string.prototype.replace` implementation.

- Added `noResolvePaths` tsconfig option to disable module resolution for environment-provided modules.

- Implemented support for void expressions, i.e `void(0)` or `void(ignoreThisReturnValue())`.

- Upgraded TypeScript to 4.4.4 and made it a peer dependency to hopefully avoid plugin issues due to mismatching TypeScript versions.

- The `$vararg` language extension can be used to access CLI arguments, now also in bundles.

- Fixed a bug regarding `baseUrl` and relative imports.

- Fixed `sourceMapTraceback: true` not working correctly for bundles.

- Fixed an issue regarding hoisting in switch case clauses.

- Added missing function context validation cases for object literals.

- Fixed a problem where awaiting rejected promises in try/catch would give the wrong result.

- Fixed an issue where chained `.then` calls on already-resolved or already-rejected promises would cause some callbacks to not fire while they should.

- Fixed source file paths in source maps being absolute, they are now relative again.
