New Features: • Document new Rakuten Advertising, Weather API, and Spreadsheets (IMAP) extractors and a ClickHouse loader in the connectors catalog, and update the connectors index and sidebar to include them. • Add a Pipeline Diagnosis page for Meltano Cloud covering manual log inspection and Melty AI-based failure diagnosis, plus a Lab landing page control section in workspace management docs. • Add August 2026 Meltano Cloud changelog entries covering MotherDuck store support, AI-powered pipeline diagnosis, security improvements, and connector upgrades. Enhancements: • Enhance connector search cards with type badges, improved theming, alphabetic sorting, truncated titles with marquee-on-hover behavior, and filter chips for extractors vs loaders. • Update Meltano Cloud store connection guides (SQL Server, ClickHouse, Snowflake) with additional static egress IP addresses and examples for firewall and network rules. • Exclude connector cards from default markdown link styling to keep their new visual design consistent. Build: • Add @phosphor-icons/react as a docs dependency for connector type icons. meltano/meltano
