Included items

Steel Computers items were removed from the draft by review. Their commits stay in the window and are not excluded in the ledger.

⭐ New

🔧 Improvements

• The Sessions API now returns active, remaining, and total concurrency quota headers on successful session creation and concurrency-limit responses. 0xnenlabs/steel 77d5a1b
• The session viewer now supports a fullscreen live view, keyboard seeking, and refreshed session details and timeline controls. 0xnenlabs/steel 0e5a4a2 0xnenlabs/steel 91f4d36
• Added a Sessions API configuration guide with task-based recipes for proxies, CAPTCHA solving, timeouts, browser behavior, and network identity. steel-dev/docs 502ec4f
• The billing dashboard now shows assigned Enterprise credits and usage rates, and session details include per-session proxy analytics. 0xnenlabs/steel 37362b4 0xnenlabs/steel 2f0f09c

🐛 Bug Fixes

• Fixed session log and agent-trace routing, authentication, and WebSocket forwarding for Box-backed sessions. 0xnenlabs/steel 02b38be 0xnenlabs/steel f9b4c86 0xnenlabs/steel a4e200a 0xnenlabs/steel 26438f7
• Fixed WebSocket proxy cleanup and connection-pressure handling that could exhaust API file descriptors and cause timeouts or failed upgrades. 0xnenlabs/steel 03d5c19 0xnenlabs/steel 3ab2490 0xnenlabs/steel cdd9c56
• Fixed session archive downloads so file changes trigger a fresh archive and concurrent downloads wait for the latest rebuild. steel-dev/steel-browser fd60dd5 0xnenlabs/steel 06ba088
• Fixed repeated /context polling that could saturate browser file operations and slow down the entire browser machine. steel-dev/steel-browser 2b41124 0xnenlabs/steel 936c6ca
• Fixed billing recovery so restored balances automatically remove funds-based blocks, temporary Metronome failures no longer blank the full billing dashboard, and concurrent signup provisioning no longer leaves organizations blocked. 0xnenlabs/steel b6aa38f 0xnenlabs/steel 810181a
• Corrected region validation so requests targeting regions without live capacity return a clear validation error instead of a retryable 503. 0xnenlabs/steel 4efe0dc steel-dev/docs 0f3f12a
• Fixed log redaction so credentials embedded in URL values are removed before API and managed-browser telemetry is recorded. 0xnenlabs/steel d06db98
