Included items

⭐ New

• Inactivity-based session timeouts: Sessions now support an inactivity timeout, so idle sessions can be released automatically after a configurable period. 0xnenlabs/steel 6950a1c steel-dev/cli a4c8414 steel-dev/cli ce3ba82 steel-dev/docs 3569933
• CLI commands for sessions and agent skills: The Steel CLI now includes sessions management commands and agent skills commands, including an interactive skills catalog flow and an --all install option. steel-dev/cli aebc657 steel-dev/cli 5b9385b 0xnenlabs/steel f6ed51b

🔧 Improvements

• Docs now include a dedicated agent skills section, with installation, authoring, and troubleshooting guidance, and the quickstart has been updated to cover skills as part of the setup flow. steel-dev/docs 3cca9f8 0xnenlabs/steel bb4fddc
• Docs pages now support markdown content negotiation, making it easier to fetch raw markdown directly from the docs site. steel-dev/docs a957fb5
• Steel API error responses are now more consistent, with clearer validation and recovery messages and standardized docs links in error payloads. 0xnenlabs/steel 2f71efc
• Session anti-bot detection now covers more systems, including DataDome, Imperva, Amazon WAF, and FunCaptcha, with detected captcha types recorded on sessions for analytics. 0xnenlabs/steel f5549e1
• Steel Browser migrated its PDF tooling to MuPDF. steel-dev/steel-browser 23fdf85

🐛 Bug Fixes

• Fixed docs pages that intermittently returned 500s when rendering raw markdown outside the prerender cache. steel-dev/docs 10d7097
• Fixed /changelog so it now redirects to the latest changelog entry instead of relying on a stale index source. steel-dev/docs b7a46d6
• Corrected billing credit grants and usage display so they align with each plan's configured credits. 0xnenlabs/steel 72dcf9e
• Fixed Steel Browser fingerprint injection so launch configs that skip fingerprint injection are respected. steel-dev/steel-browser f721915

🏡 Housekeeping

• Docs analytics moved to a shared GTM container, replacing the standalone Reo script setup. steel-dev/docs 7837ff0 steel-dev/docs b78cfae

Discarded items

• Added social card author and published time metadata for changelog pages. — Useful polish, but too minor for the weekly changelog. steel-dev/docs 6e7f679
• Made the scheduled changelog draft job idempotent instead of time-gated. — Internal publishing workflow change, not product-facing. steel-dev/docs a1bd0f5
• Added captcha balance monitoring and managed-browser log ingestion in internal systems. — Operational work without a clear user-facing product change. 0xnenlabs/steel 54cd42f 0xnenlabs/steel d1c2765
• Shipped core-browser spoofing work and related image/build fixes. — Potentially significant, but the commit history does not make the user-facing rollout or supported surface area clear enough to describe confidently. 0xnenlabs/steel d055bec 0xnenlabs/steel 9aaa786
• Automatic infra image updates and logging cleanup in whipit. — Routine infrastructure maintenance with no direct user-facing change to call out. steel-dev/infra a2cb6ca steel-dev/infra f75a223
