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.
