This is a gateway-only `extended-stable` release, which is our current equivalent to LTS. This release is OpenClaw from the end of August 2026, plus critical security updates, reliability and performance fixes, and features like new model support. The latest version of OpenClaw at the time of this release is [2026.9.6](https://github.com/openclaw/openclaw/releases#release-v2026.9.6)
## 2026.8.33
### Highlights
- **Current flagship models:** add Meta Muse Spark 1.3, Anthropic Fable 5.1, OpenAI GPT-6 Astra, and OpenAI/fal GPT Image 2.5 support to the extended-stable line. (#135638, #136553, #137550, #143068, #143069)
- **Complete GPT-5.6 family support:** preserve Sol, Terra, and Luna catalog, routing, migration, image, vision, and thinking behavior, including Ultra reasoning across model-runtime boundaries and Bedrock tool-result images. (#135397, #149336)
- **Extended-stable security rollup:** reconcile all repository advisories that affect 2026.8.2, harden Prometheus metrics authorization and Discord asset/voice ownership, and clear the production Nodemailer advisory gate. (#136700, #137433, #140334, #140903)
### Changes
- **Extended-stable release preparation:** normalize OpenClaw, all publishable plugins, and native version metadata to 2026.8.33 while retaining the release-line-compatible publication workflows from 2026.8.2.
