What is LibreSpeed?

LibreSpeed 6.3 adds shareable result images and fixes Safari upload tests.

LibreSpeed made its rewritten design the default in 6.0.0, then turned to measurement in the 6.2.x line with a connection-stability test and an upload-inflation fix. 6.3.0 in September added a shared-result image matching the chosen design, SERVER_LIST_URL support in frontend Docker mode, and a fix that puts modern Safari on the standard upload path. 6.3.1 in October fixed mixed-content filtering in server selection and the mobile gauge.

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.

2.5

LibreSpeed 6.3 adds shareable result images and fixes Safari upload tests.

◆ Current state

LibreSpeed made its rewritten design the default in 6.0.0, then turned to measurement in the 6.2.x line with a connection-stability test and an upload-inflation fix. 6.3.0 in September added a shared-result image matching the chosen design, SERVER_LIST_URL support in frontend Docker mode, and a fix that puts modern Safari on the standard upload path. 6.3.1 in October fixed mixed-content filtering in server selection and the mobile gauge.

◆ Where it's heading

With the design migration done, releases focus on measurement accuracy and easier Docker deployment. Minor versions arrive every month or two.

◆ Prediction

Expect further accuracy and deployment fixes in 6.3.x; no larger feature is signalled.

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.
