@@ -9,6 +9,7 @@ The version headers in this history reflect the versions of Apollo Server itself
 - `apollo-server-core`: Upgrade TS to 3.7.3 [#3618](https://github.com/apollographql/apollo-server/pull/3618)
 - `apollo-server-cloud-functions`: Transmit CORS headers on `OPTIONS` request. [PR #3557](https://github.com/apollographql/apollo-server/pull/3557)
 - `apollo-server-caching`: De-compose options interface for `KeyValueCache.prototype.set` to accommodate better TSDoc annotations for its properties (e.g. to specify that `ttl` is defined in _seconds_). [PR #3619](https://github.com/apollographql/apollo-server/pull/3619)
+- `apollo-engine-reporting`: Fix regression introduced by [#3614](https://github.com/apollographql/apollo-server/pull/3614) which caused `PersistedQueryNotFoundError`, `PersistedQueryNotSupportedError` and `InvalidGraphQLRequestError` errors to be triggered before the `requestDidStart` handler triggered `treeBuilder`'s `startTiming` method. This fix preserves the existing behavior by special-casing these specific errors.  [PR #3638](https://github.com/apollographql/apollo-server/pull/3638) [Issue #3627](https://github.com/apollographql/apollo-server/issues/3627)
