Adapter history
S3 Adapter (Source)
LKFLOW_S3_SOURCE · current 1.0.0 · configuration
1.0.0
Released 2026-09-17

1.0.0
Released 2026-09-17

Library history
Library versions are immutable: a published version is never edited, and a fix ships as a new version. A node stays pinned to the version it was built against until you move it forward.
