The initial release of my iMessage backup/exporter software received some amazing feedback from this sub. Since then it has improved a lot:

• Mountain Sage increased performance and cleaned up exported attachments
• Lemonade Berry added date filter support and made PDF generation slightly less pesky
• Coyote Mint was the first release with community contributions and expanded support for non-MacOS platforms
• Cliff Aster added support for parsing unencrypted iOS backups as well as restoration of recently deleted messages
• Arroyo Lupine was a maintenance release that polished iOS support and reworked handling of attachment data
• Checker Mallow polished HTML exports by adding several quality-of-life features and fixed several bugs

Finally, the most recent release, Laurel Sumac, added iOS 17 and macOS Sonoma support!

I have found this software very useful to preserve my data and I hope you all do as well.
