1.2.0

Release Notes

Bug Fixes

  • Fixed dedup GC incorrectly deleting still-referenced blobs, causing permanent 404 on download-message
  • Fixed download-message to self-heal when content blob is missing: automatically re-fetches from IMAP and restores the blob; 404 is only returned if the recovery itself fails
  • Fixed wrong schema field used for attachment hash lookup in cleanup_unused_content

Features

  • search-messages now supports filtering and sorting by server-controlled timestamps: internal_date (IMAP INTERNALDATE) and ingest_at (archival time), enabling reliable incremental sync cursors
  • (ui) Strip remote content from emails when viewed #54

Refactor

  • Migration merge: use searchable_segment_ids() to reduce unnecessary file access (#261)
