This release expands the file formats Flowfile can read and write, makes the whole node palette searchable by tags, and brings a big wave of improvements to the in-browser editor (flowfile-editor) — alongside fixes to output paths and Save-As.

New file formats — Arrow IPC, NDJSON & Avro (#536)

Flowfile can now read and write three more formats, in both the visual editor and the Python API:

  • Arrow IPC / Feather (.arrow, .ipc, .feather), NDJSON / newline-delimited JSON (.ndjson, .jsonl), and Avro (.avro)
  • The Read Data and Write Data nodes detect and configure these alongside the existing CSV, Excel, and Parquet support
  • Python API gains read_ipc / read_ndjson / read_avro (plus lazy scan_ipc / scan_ndjson) and write_ipc / write_ndjson / write_avro
  • Pick a compression codec per format when writing — Parquet (zstd/snappy/gzip/lz4/brotli), IPC/Arrow (lz4/zstd), NDJSON (gzip/zstd), Avro (snappy/deflate)

Searchable node tags (#525)

  • Every node now carries searchable tags, so typing concepts like csv, vlookup, dedupe, window, s3, or kafka surfaces the right node even when the term isn't in its name
  • Palette search now matches both node names and tags across the desktop and web designer
  • In the browser editor, full-app-only nodes (Database, Cloud, REST API, Kafka, Google Analytics, SQL Query, Python Script, Window Functions) are now discoverable — hidden by default but revealed via a new "Show full-app nodes" toggle or by search, shown locked with a "Learn more" docs link, plus a node info popup

Browser editor (flowfile-editor) improvements

The in-browser WASM editor got a lot broader this release:

  • Five new nodes — Formula, Cross Join, Union, Record ID, and Rename — broadening what you can build with zero backend (#518)
  • Dynamic Rename node to bulk-rename columns by prefix, suffix, formula, or first-row values; a richer Formula function browser with a category tree, hover docs, and type-aware autocomplete; and fixed preview rendering for date/time/decimal/binary columns (#519)
  • Delete connections by hovering an edge and clicking the remove button (#523)
  • Explicit-only execution — opening a node's Settings or Table panel no longer silently runs your pipeline; data is computed only when you run it (Ctrl+E / Run Now / Apply / Fetch data). Single-click opens Settings, double-click opens Settings + Table (#521)

Fixes & improvements

  • Output paths (desktop): output nodes now default to a real, writable directory (your last write folder or home) instead of an ambiguous ., and existing nodes carrying . are converted to an absolute path on open. Write history is tracked separately from the file browser (#529)
  • Save-As: saving a flow to the catalog under a new name now creates a copy instead of deleting the original, flow names can be free-form labels (auto-slugified on disk), and the catalog picker hides flows whose backing file was deleted (#522)
  • Lighter installs: database writes no longer require pandas (SQLite uses sqlite3, others use SQLAlchemy Core), and the Database Writer node now validates schema/table names inline (#528)
  • New documentation for the REST API Reader, Kafka Source, Google Analytics Reader, Window Functions, and SQL Query nodes (#535)
  • The browser editor is now positioned as a standalone, embeddable npm package — npm install flowfile-editor (#520)
  • Internal cleanup of the WASM editor — dead code and debug logging removed (#532)
  • Dependency bumps: axios 1.15.2 → 1.16.0 and form-data 4.0.5 → 4.0.6 (frontend), vite / plugin-vue / vitest (wasm) (#511, #530, #531, #510)
