 -   Node 12 is no longer officially supported as it has gone end of life as of 2022-04-30. It might still work, but may stop working at any time.
 -   Dropped support for TypeScript before 4.6.
+-   TypeDoc will now produce warnings for bracketed links (`[[ target ]]`). Use `{@link target}` instead. The `{@link}` syntax will be recognized by [TypeScript 4.3](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-4-3.html#editor-support-for-link-tags) and later and used to provide better intellisense. TypeDoc version 0.24.0 will remove support for `[[ target ]]` style links.
 -   `extends` in typedoc.json is now resolved using NodeJS module resolution, so a local path must begin with `./`.
 -   In the JSON output for `DeclarationReflection`s, `getSignature` is no longer a one-tuple.
 -   In the JSON output for `DeclarationReflection`s, `setSignature` is no longer a one-tuple.

 -   TypeDoc will now automatically inherit documentation from classes `implements` by other interfaces/classes.
 -   Fixed `@inheritDoc` on accessors, #1927.
 -   JS exports defined as `exports.foo = ...` will now be converted as variables rather than properties.
