Apr 1, 2025April 2025 (apache/nifi): Delivered enhanced ListSmb capabilities with startup listing strategies and regex-based filtering, including UX clarity improvements. These changes increase configurability and reliability for SMB listing workflows, enabling teams to tailor listings (all, new, or since a timestamp) and filter files by name/path while avoiding noise with the renamed Ignore Files with Suffix filter. No major bugs fixed this month. These efforts contributed to improved data ingestion reliability, operational efficiency, and maintainability.

Mar 1, 2025March 2025 monthly summary for apache/nifi: In the Google Drive integration, delivered two focused updates to improve accuracy and metadata. The Shared Drive name retrieval bug in ListGoogleDrive was fixed, ensuring actual drive names are displayed when folderId matches a driveId. In addition, metadata depth was expanded for Google Drive processors: FetchGoogleDrive now exposes owner, last modifying user, web view link, and web content link; ListGoogleDrive now provides parent folder IDs/names and listed folder IDs/names, enhancing file discovery, governance, and automation. These changes were implemented in commit 05007f14d7c938bc3c4af615cb58ceee17dfa652 (NIFI-14376) and 64a4d2b48f8cde10759f22c7f03e7f0ccd7f84a4 (NIFI-14388).
