rustmailer/bichon 1.5.0

Release 1.5.0

on GitHub

🚀 Features

• imap: add message size check before download

🐛 Fixes

• migration: open NewIndexWriter once across all migration segments #287

• Issue: Opening/closing Fjall DB per segment triggered an lsm-tree checksum error (ChecksumType mismatch) as data accumulated.

• Fix: Instantiated NewIndexWriter once before the loop and passed it via &mut reference, avoiding the reopen failure path.

• imap: Add fallback UIDVALIDITY support for non-compliant IMAP servers #288

• Issue: Non-compliant servers (like Tencent Enterprise Mail) lack UIDVALIDITY, breaking sync.

• Fix: Introduced generate_synthetic_uidvalidity() (hash-based) to enable incremental sync and system folder support.
