dlt 1.22.1 Release Notes

Core Library

• feat(workspace): add default exclude patterns for file selector (#3661 @canassa) — WorkspaceFileSelector now ships with DEFAULT_EXCLUDES (.git/, .venv/, __pycache__/, node_modules/, etc.) so well-known non-deployable paths are always excluded, even without a .gitignore.
• feat(workspace): add ignore_file_found attribute to WorkspaceFileSelector (#3663 @canassa) — Consumers can now check whether the configured ignore file (e.g. .gitignore) was actually found.
• Dashboard cleanup and refactor (#3660 @sh-rp) — Broke up monolithic utils.py and dlt_dashboard.py into focused modules with simplified UI across all sections.
• Sets default MCP transport to http-stream (#3624 @rudolfix) — Swaps sse for http-stream transport for built-in MCP servers and annotates pipeline trace schema.
• Fixes data inspection tools (#3664 @rudolfix) — Allows incomplete columns in schema converters, attaches pipeline in every command, adds new allowed layout for sources.<name>.api_key.
• Fix: Mermaid doesn't handle incomplete columns (#3659 @anuunchin) — .to_mermaid() now handles columns missing the data_type field instead of crashing.
• Fix: ClickHouse makes reads sequential by default (#3651 @rudolfix) — Enforces select_sequential_consistency to fix flaky tests caused by ClickHouse's eventual consistency model.
• Fix: data quality checks component (#3647 @zilto) — Fixes silently broken data quality checks code caused by upstream dlthub changes.
• Fix: autouse test storage dir not empty (#3648 @tetelio) — Fixes intermittent CI failure in read-only file deletion by aligning with shutil docs.
