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 Prowler?

Prowler is turning its scanner into an agent that can operate the platform, and charging for it.

Prowler ships roughly weekly, alternating feature minors with patch releases of API, UI and SDK fixes. The dominant thread across the last two months is Lighthouse AI, which went from a chat assistant reading findings (5.33.0) to one that takes actions (5.35.0) to one that reaches every tool family the Prowler MCP server exposes, including users and roles (5.37.0). Around it, the platform side has been filling in security-operations workflow: findings triage with lifecycle states, Jira dispatch for finding groups, and Attack Paths query tracking.

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.

Prowler is turning its scanner into an agent that can operate the platform, and charging for it.

◆ Current state

Prowler ships roughly weekly, alternating feature minors with patch releases of API, UI and SDK fixes. The dominant thread across the last two months is Lighthouse AI, which went from a chat assistant reading findings (5.33.0) to one that takes actions (5.35.0) to one that reaches every tool family the Prowler MCP server exposes, including users and roles (5.37.0). Around it, the platform side has been filling in security-operations workflow: findings triage with lifecycle states, Jira dispatch for finding groups, and Attack Paths query tracking.

◆ Where it's heading

The open-source CLI scanner is becoming the data layer for a paid agentic product. The 5.34.0 renaming made the split explicit — Prowler CLI and Prowler Hub stay open, while Cloud, Private Cloud, Lighthouse AI and MCP are the commercial surface — and every Lighthouse release since carries a subscription-only note. The technical bet is that RBAC is a sufficient safety boundary for an agent: Lighthouse can do whatever the asking user could do, which is what allows it to be handed administrative tools rather than read-only ones.

◆ Prediction

Expect the next Lighthouse releases to push into unattended operation — scheduled or event-triggered agent runs rather than chat-initiated ones — since scan scheduling and alert rules are now inside its reach. Continued patch releases fixing Attack Paths graph behaviour on Neo4j and Neptune suggest that subsystem is still settling.
