What is BorgBackup?

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.

What is k0s?

k0s ships one fix four times a day — the cost of keeping four Kubernetes branches current.

Four patch releases were cut within eleven minutes of each other on 27 July, one per supported branch from 1.33 through 1.36, each carrying the same konnectivity server-count fix backported alongside its own set of dependency bumps — Kubernetes, etcd, containerd, Go, Helm, Calico, Alpine. Nearly every line is authored by k0s-bot. The only forward-looking entry is v1.37.0-alpha.1, which opens the next minor with an autopilot update-window fix and an etcd 3.7.0 release candidate.

Borg's long-running 2.0 beta finally landed packs — and warned it dropped back to alpha quality.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.

5.0

k0s ships one fix four times a day — the cost of keeping four Kubernetes branches current.

◆ Current state

Four patch releases were cut within eleven minutes of each other on 27 July, one per supported branch from 1.33 through 1.36, each carrying the same konnectivity server-count fix backported alongside its own set of dependency bumps — Kubernetes, etcd, containerd, Go, Helm, Calico, Alpine. Nearly every line is authored by k0s-bot. The only forward-looking entry is v1.37.0-alpha.1, which opens the next minor with an autopilot update-window fix and an etcd 3.7.0 release candidate.

◆ Where it's heading

The release stream is almost entirely supply-chain maintenance: k0s bundles a full Kubernetes distribution, so its job is to absorb upstream patch releases across every supported branch and republish them quickly. That makes cadence a poor proxy for progress here — four same-day tags represent one fix, not four. Product-level change surfaces only in alpha releases of the next minor, where things like autopilot behaviour and etcd major-version prep appear before being backported.

◆ Prediction

Expect the 1.37 alpha line to continue toward a stable release while the four maintained branches keep receiving synchronised dependency and backport batches.
