Claude Code 2.1.85 adds hook if filters, new MCP header env vars, transcript timestamps, and fixes for /compact overflow, remote leaks, auth flow, and terminal bugs. Upgrade if your workflow depends on hooks or long sessions, and use the new cloud auto-fix flow for unattended PR cleanup.
if filters, MCP header env vars for multi-server helpers, and transcript timestamps for scheduled tasks, according to the 2.1.85 changelog./compact failing with "context exceeded," a remote-session memory leak, and repeated ECONNRESET retries during edge churn in the release thread.The engineering payload in 2.1.85 is mostly about making automation less brittle. Anthropic added CLAUDE_CODE_MCP_SERVER_NAME and CLAUDE_CODE_MCP_SERVER_URL to MCP headersHelper scripts so one helper can serve multiple MCP servers, and it added an if field for hooks using permission-rule syntax like Bash(git *); the changelog says that filter is meant to "reduce process spawning overhead" in hook-heavy setups changelog thread. Transcript logs now also mark when /loop and CronCreate tasks fire, which should make unattended runs easier to debug release notes.
The fixes target several failure modes engineers actually hit in long-running sessions. The biggest one is /compact, which previously could fail with "context exceeded" when the compaction request itself no longer fit; 2.1.85 also fixes a memory leak in interrupted remote streaming sessions, step-up MCP OAuth reauthorization when a refresh token exists, and a bug that left some terminals stuck in enhanced keyboard mode after exit 2.1.85 changelog. The same thread notes improved @-mention autocomplete on large repos and a switch from WASM yoga-layout to pure TypeScript for better scroll performance with large transcripts release thread.
Separate from the CLI patch, Claude Code's cloud session flow now has an Auto fix toggle for PR-following sessions. The UI text in the product screenshot says it can "Proactively fix CI failures and review comments" and may post comments on the user's behalf, while Auto merge remains a separate control. A supporting post says the feature is already available across web, mobile, and desktop sessions launch screenshot.
That matters because practitioners are increasingly treating the hosted surface as more than a companion app. One user wrote that "more than 50%" of their Claude Code usage is now on the web and framed the shift as a productivity gain, with thread context claiming "Permission prompts are a thing of the past" for that workflow practitioner report. Taken together, today's changes point in the same direction: less local babysitting, more background PR maintenance, and fewer session-management failures when runs get long 2.1.85 changelog.

releaseOpenAI rolled out Codex plugins across the app, CLI, and IDE extensions, with app auth, reusable skills, and optional MCP servers. Teams should test plugin-backed workflows and permission models before broad rollout.
releaseCline launched Kanban, a local multi-agent board that runs Claude, Codex, and Cline CLI tasks in isolated worktrees with dependency chains and diffs. Teams can use it as a visual control layer for parallel coding agents on repo chores that split cleanly.
releaseMistral released open-weight Voxtral TTS with low-latency streaming, voice cloning, and cross-lingual adaptation, and vLLM Omni shipped day-0 support. Voice-agent teams should compare quality, latency, and serving cost against closed APIs.
