AI agents: use the documentation index at llms.txt to locate machine-readable pages. This section is indexed by https://docs.particular.net/nservicebus/llms.txt. The markdown version of this page is served as plain text. An MCP server at /mcp serves the same content via the search_docs and read_doc tools; it is read-only and needs no credentials. Markdown versions of documentation pages are available by appending .md to the page URL. Directory URLs use index.md. They are served as text/plain because some retrieval backends reject text/markdown.

AWS Lambda Upgrade from 2 to 3

Component: AWS Lambda (SQS)

Upgraded NServiceBus.AmazonSQS version 8 which upgrades AWS SDK to version 4

The AWS SDK introduces breaking changes, such as returning null instead of empty collections. The lambda package has been updated internally to accommodate these changes.

If your application code directly uses the AWS SDK and is affected by these changes, you’ll need to adjust your code accordingly by following the AWS SDK v4 upgrade guidelines.
