+
+**BREAKING**: The `buildTechInsightsContext` function now takes an additional
+field in its options argument: `tokenManager`. This is an instance of
+`TokenManager`, which can be found in your backend initialization code's
+`env`.
+
+```diff
+ const builder = buildTechInsightsContext({
+   logger: env.logger,
+   config: env.config,
+   database: env.database,
+   discovery: env.discovery,
+   scheduler: env.scheduler,
++  tokenManager: env.tokenManager,
+   factRetrievers: [ /* ... */ ],
+ });
+```
