Borg's long-running 2.0 beta finally landed packs — and warned it dropped back to alpha quality.
Borg runs two trains in the same feed. The 1.4.x line is explicitly a refreshed 1.2 — same features and behaviour, with the riskier changes isolated so they could be tested before shipping — and it has taken over as the recommended branch since 1.2.9 was called the final 1.2 release. The 2.0 line has been in beta since well before this window, at b22 as of July 2026, with every release carrying a do-not-use-on-production warning. b22 introduced packs and the maintainers told users to expect alpha stability despite the beta number.
Tailscale is turning the tailnet itself into something a script provisions and pages through.
Two threads run in this window. The client and operator releases are maintenance-grade — a Funnel regression fix, library-only container updates, Kubernetes operator work on PeerRelays, workload identity federation and IPv6 egress. The more consequential thread is the tailnet management API: creation landed in alpha at the end of July, and the list endpoint has now been paginated, with a hard 100-result default for organizations holding more.

The split is the story: one branch exists purely to keep existing users safe and current, while the other rewrites how data is stored on disk. Packs are the kind of change that determines whether 2.0 ever ships — repository layout affects performance, resumability and every recovery path at once, and the honesty about stability regressing suggests the shakeout is still ahead. The 1.4 line will keep absorbing fixes and low-severity security work in the meantime, and the b18 corruption bug shows why the two trains are kept firmly apart.
Expect further 2.0 betas focused on packs stability before anything resembling a release candidate, with 1.4.x continuing to carry routine fixes for production users.

Tailscale has spent this period on two different customers at once. The operator work serves platform teams running Tailscale inside Kubernetes, where the gaps being closed are reconciliation loops, stale DNS ConfigMaps and cert-renewal backoff. The tailnet API work serves a different shape entirely: organizations holding enough tailnets that a hundred is a page boundary, which only happens when tailnets are allocated per customer or per environment rather than per company. The second thread is the one that changes what Tailscale is for.
Pagination on list implies the creation API is being used at volume, so expect the alpha to gain the management operations a fleet needs — policy templating or bulk configuration across tailnets. The client release line looks settled on 1.102.x maintenance in the near term.
