Releases

Checklist • I have read the contribution guide Summary by Sourcery Expand and reorganize connector and AI documentation while renaming the Changelog experience to Releases with backward-compatible redirects. New Features: • Add connector documentation for Google Ads, Nextdoor, PostgreSQL, Snowflake, Google BigQuery, and MotherDuck. • Add a dedicated Meltano AI documentation section covering Claude-based development, pipeline diagnosis, and diagnose-and-act alerts. • Add Google BigQuery store setup documentation and document Arrow batch support across additional connectors and stores. Enhancements: • Refresh existing connector documentation with clearer descriptions, setup guidance, stream coverage, replication details, configuration references, and consistent support links. • Replace the DuckDB target documentation with MotherDuck documentation and update connector navigation and search listings. Build: • Update documentation package lock metadata. Deployment: • Rename the documentation release pages and routes from Changelog to Releases for Meltano Open and Meltano Cloud, with redirects preserving existing Changelog URLs. Documentation: • Move the Claude and pipeline diagnosis documentation into the new Meltano AI section and update navigation. meltano/meltano
