What is BorgBackup?

Borg 2.0 beta 25 breaks repositories to swap its hash and repository format.

BorgBackup's 2.0 beta line is still making breaking format changes. Beta 25 requires new repositories: it moves store object names to blake3, replaces several repository objects with an ini-style config, removes the none-sha256 and none-blake3 modes in favor of authenticated ones, and protects lock, index and cache objects with the repository key. The stable 1.4 line remains the production track.

What is Windmill?

Windmill adds workspace roles and AI decision steps as its agent tooling fills out.

Windmill is an open-source workflow and internal-tools platform adding AI and governance features quickly. Mid-September brought a headless Chat SDK for chat-mode flows, per-run tool selection for AI agent steps, origin allowlists for HTTP routes, GitHub CI gating and GitLab git-sync parity. October added an AI decision step, operator builder rights and default Developer and Operator workspace roles.

Borg 2.0 beta 25 breaks repositories to swap its hash and repository format.

◆ Current state

BorgBackup's 2.0 beta line is still making breaking format changes. Beta 25 requires new repositories: it moves store object names to blake3, replaces several repository objects with an ini-style config, removes the none-sha256 and none-blake3 modes in favor of authenticated ones, and protects lock, index and cache objects with the repository key. The stable 1.4 line remains the production track.

◆ Where it's heading

Twenty-five betas in, the format is not settled, but this beta is decisive: it removes old modes and object types, which narrows what 2.0 has to support. Treating lock and cache objects as keyed data also extends the security model beyond archive contents.

◆ Prediction

Further betas are likely to keep requiring new repositories until the format freezes, so a release candidate should not be assumed soon. The 1.4 line stays the safe choice until then.

5.0

Windmill adds workspace roles and AI decision steps as its agent tooling fills out.

◆ Current state

Windmill is an open-source workflow and internal-tools platform adding AI and governance features quickly. Mid-September brought a headless Chat SDK for chat-mode flows, per-run tool selection for AI agent steps, origin allowlists for HTTP routes, GitHub CI gating and GitLab git-sync parity. October added an AI decision step, operator builder rights and default Developer and Operator workspace roles.

◆ Where it's heading

Windmill is building AI agents into flows as first-class steps with controls over which tools they can use, while adding the role and access model enterprises need to let more people build. Developer workflow parity across Git hosts continues in parallel.

◆ Prediction

Expect more AI agent controls and role-based permissions; whether the Chat SDK grows into a hosted chat product is unclear.
