Deduplicating encrypted backup program

BorgBackup 2.0's new PACKS storage architecture enters rapid beta iteration while the stable 1.4 track continues receiving security fixes.

Current state
BorgBackup is running two parallel release tracks: a stable 1.4.x series receiving security fixes and feature updates, and an active 2.0.0 beta series that introduced PACKS — a new fundamental storage architecture — in b22. The 2.0.0 betas are explicitly flagged as not suitable for production repositories.
Where it's heading
PACKS represent BorgBackup's most significant architectural change: a new way to organize how backup data is stored on the backend. The rapid progression from b21 through b24 suggests active development iteration toward a stable 2.0 release. Meanwhile, 1.4.x continues as the production-safe track, with 1.4.5 including a low-severity security fix.
Prediction
BorgBackup will continue beta iterations on 2.0 working toward PACKS stability, with a release candidate phase for 2.0 likely within a few months given the steady cadence. The 1.4 track will receive maintenance until 2.0 reaches GA.
