  1. v2.6.0

    Coming soon

    Apple Mail and Thunderbird exports open directly

    • New Apple Mail export folders (.mbox packages) now open directly — no need to dig out the inner “mbox” file.
    • New Mailbox files without an extension — like Thunderbird's INBOX or Sent — open directly, no renaming to .mbox required.

  2. v2.5.0

    Latest

    Safer HTML and smarter search

    • Security Email HTML is now sanitized before display — scripts, iframes and other active content are stripped, on top of the existing remote-image blocking.
    • Improved Free-text search now looks inside message bodies too, not just subject and sender — so a plain word finds everything.
    • Fixed Hardened parsing of very large files so a message split across read buffers can never inflate the message count.

  3. v2.4.1

    Accurate version info and code redemption

    • Fixed The About window now always shows the real installed version.
    • New Added a «Redeem Code» button so you can use Mac App Store promo codes for the Pro upgrade.

    Pro is now a simple one-time purchase

  5. v2.3.0
