# Conflicts:

#	docs/production-deployment/worker-deployments/serverless-workers/aws-lambda.mdx

Resolve conflicts from the Cloud Run restructure on main:

- Move the branch's encyclopedia edits (Versioning row, High Availability
  row) onto the split page at encyclopedia/workers/serverless-workers/index.mdx
  and generalize them across providers.
- Point the Lambda deploy guide's timeout caution at
  /troubleshooting/serverless-workers/aws-lambda#validate-connection, since this
  branch replaced the #check-wci-detecting-tasks section main linked to.
- Rebuild sidebars.js on main's hoisted per-SDK develop categories, re-adding
  the Java and .NET Serverless Workers categories.
- Add serverlessWorkersLambda: publicPreview and point the Lambda-specific
  pages at it. Provider-neutral and Cloud Run pages stay Pre-release.
- Fix the Java and .NET links to /serverless-workers#tuning-for-long-running-activities,
  which now lives on the Lambda encyclopedia page.

AWS Lambda is in Public Preview while GCP Cloud Run stays in Pre-release, so
the provider-neutral pages now show a Public Preview banner that says which
provider that covers and how to request Cloud Run access.

Set the stage inline with type="publicPreview" on those pages and drop the
serverlessWorkers key, leaving one key per provider in featureReleaseTypes.js.
Also add the banner to the five SDK Serverless Workers index pages, which had
none.
