Changelog

v1.5.2 May 18, 2026 +

• Resume — Removed a misleading log line that said “Will continue filling it.” for incomplete batches that were not going to be backfilled

v1.5.1 May 15, 2026 +

• Security — ZIP paths, output directories, and staging directories are now validated against the file-picker approval set before use
• Security — ZIP central-directory metadata validated before indexing: member cap, size cap, and symlink blocking
