OpenClaw published v2026.8.33 early Tuesday, adding a new Gateway-only extended-stable release for operators who want a slower line than the current 2026.9.x builds.
The release notes describe extended-stable as OpenClaw's current LTS-equivalent lane. This cut is based on OpenClaw from the end of August 2026, then layered with selected security updates, reliability fixes, performance work, and model-support backports. The latest regular release remains v2026.9.6, so v2026.8.33 is not a newer feature train. It is a maintained alternative for deployments that value a narrower upgrade surface.
What Changed
The headline item is that the extended-stable Gateway now carries several current model integrations without forcing operators onto the newest September line.
The release notes call out support for:
- Meta Muse Spark 1.3.
- Anthropic Fable 5.1.
- OpenAI GPT-6 Astra.
- OpenAI and fal GPT Image 2.5.
- GPT-5.6 Sol, Terra, and Luna continuity across catalog, routing, image, vision, and thinking paths.
That matters for teams running a conservative Gateway build while still needing access to current model catalogs. The backports also include Bedrock tool-result image handling and Ultra reasoning behavior across model-runtime boundaries.
Security Rollup
The security portion is the clearest reason to pay attention. OpenClaw says this extended-stable release reconciles repository advisories affecting 2026.8.2, hardens Prometheus metrics authorization, tightens Discord asset and voice ownership behavior, and clears the production Nodemailer advisory gate.
Individual fixes include:
- Rejecting Prometheus metric scrapes without the configured operator-read scope.
- Enforcing sender media policy for Discord guild asset uploads.
- Preserving Discord speaker and playback ownership across voice lifecycle transitions.
- Moving the IMAP dependency graph to Nodemailer 9.1.1 to clear address-parser denial-of-service and related advisories.
Those are not cosmetic changes. They sit directly on monitoring access, media ownership, voice ownership, and dependency security, which are exactly the areas self-hosted Gateway operators should be careful about when they defer major upgrades.
Reliability Fixes
The release also includes several operational repairs. Doctor now preserves explicitly enabled skills during automatic updates. Generated images are retained when a later tool call fails. Matrix verification refreshes device trust state before reporting it. Discord consult cancellation records host-cancelled realtime consults as cancellations instead of falling into a generic error path.
There is also an iOS release-validation dependency update after a WebRTC binary artifact was withdrawn. That is mostly packaging hygiene, but it is the kind of maintenance that keeps a long-lived release line installable.
Who Should Use It
v2026.8.33 is most relevant if you are pinned to the August Gateway line and want security and reliability fixes without adopting the latest 2026.9.x release.
If you are already on the September stable line, this release is context rather than an upgrade target. The release notes explicitly point readers to 2026.9.6 as the current latest version of OpenClaw.
For conservative deployments, though, this is a meaningful maintenance cut: newer model support, security rollups, and targeted Gateway reliability work, all packaged for the extended-stable lane.
