OpenClaw 2026.7.1-beta.2: GPT-5.6 Support and External Harness Attachment

OpenClaw’s July 2026 release cycle is in full swing, with two beta releases dropping in the first week. openclaw 2026.7.1-beta.2 (July 5) is the latest preview, bringing two significant features to the foreground.

GPT-5.6 Support

OpenClaw now recognizes the GPT-5.6 model family across catalog, capability, and runtime selection paths. The implementation, contributed by @steipete-oai (PR #98333), means OpenClaw can properly route, reason about, and execute agent turns using GPT-5.6 as a backend — giving users access to OpenAI’s newest flagship model through OpenClaw’s multi-model gateway.

External Harness Attachment

The second headline feature is openclaw attach — a new CLI command that launches an external harness (such as an interactive Codex-style workflow) against an existing Gateway session. This makes it significantly easier to resume, inspect, and collaborate on in-progress agent sessions without disrupting their state. Thanks to @anagnorisis2peripeteia and @obviyus for the contribution.

Meanwhile: Stable v2026.6.11

For those preferring stability over beta features, v2026.6.11 (June 30) remains the recommended current release. It focuses on “rough edges that make OpenClaw feel less dependable” — fixes for misplaced replies, stuck sends, reconnects, model setup failures, and safer admin defaults.
