-Updates tech-insights to use backend-tasks as the Fact Retriever scheduler.
+This backend now uses the `@backstage/backend-tasks` package facilities for scheduling fact retrievers.
+
+**BREAKING**: The `buildTechInsightsContext` function now takes an additional field in its options argument: `scheduler`. This is an instance of `PluginTaskScheduler`, 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,
+   factRetrievers: [ /* ... */ ],
+ });
