+* The `Type` and `Symbol` classes have been deprecated and will be empty in newly extracted databases, since the TypeScript extractor no longer populates them.
+  This is breaking change for custom queries that explicitly relied on these classes.
+  Such queries will still compile, but with deprecation warnings, and may have different query results due to type information no longer being available.
+  We expect most custom queries will not be affected, however. If a custom query has no deprecation warnings, it should not be affected by this change.
+  Uses of `getType()` should be rewritten to use the new `getTypeBinding()` or `getNameBinding()` APIs instead.
+  If the new API is not sufficient, please consider opening an issue in `github/codeql` describing your use-case.

+* The TypeScript extractor no longer relies on the TypeScript compiler for extracting type information.
+  Instead, the information we need from types is now derived by an algorithm written in QL.
+  This results in more robust extraction with faster extraction times, in some cases significantly faster.
