Night shift report

WHY THIS MATTERS: All the official SDKs moved up a minor version together (Python 2.2.0, TypeScript 1.2.0, Java 3.2.0, Go/Ruby 2.2.0, C# 13.2.0, PHP 1.2.0, ant CLI 2.2.0). They add message threads, a new beta where the server keeps the conversation history, so each request sends only the new turns. That changes how people build multi-turn apps. Separately, a quiet Claude Code docs edit can break existing self-hosted runner wrappers: from v2.1.309 the runner reserves file descriptors 4 and 5. The docs' own earlier example saved stdin on fd 4, so anyone who copied it now collides with the runner.

HIGHLIGHTS:

• Message threads (beta), both SDKs: client.beta.messages.thread(...) takes the same arguments as create(). thread.send(...) sends only the new message, and thread.tool_runner() runs the tool loop over the thread. New types: BetaMessageThreadParam, BetaThreadCreateParams, BetaThreadContinueParams. There is no platform docs page for it yet. It only appears in the SDK changelogs and in anthropic-sdk-python/helpers.md.
• New Admin analytics endpoints: GET /v1/organizations/analytics/usage and /analytics/cost (beta) break usage and cost down by dimension. Each can group by actor (API key, user, service account, or federated AWS/Azure/GCP/OIDC identity), service tier, speed and inference geo. The older usage/cost reports are now marked legacy.
• Possible breaking change for self-hosted runner wrappers (self-hosted-environments-configuration.md): from v2.1.309 runners reserve fds 4 and 5 for the child process, so wrappers must not close or reuse them. The recommended backgrounding pattern moved from exec 4<&0 to exec 9<&0, and fds 6-9 are listed as safe on every version.
• Tool runner fixes in Python 2.2.0 and TS 1.2.0: set_messages_params() / append_messages() / pushMessages() had regressions in the 2.1/1.1 releases from two days ago (lost betas/workspace_id, function tools that stopped running, history mutation). These releases fix them. Anyone on 2.1.0/1.1.0 who uses the tool runner should upgrade.
• Cloud environments UI (cloud-environments.md): the environment dialog now uses rows (Network access / Setup script / Environment variables / Network secrets). Setup scripts can be loaded from a file up to 64 KB with Choose file.
• security-guidance plugin no longer names a default model ("Claude Opus 4.7" became "a Claude Opus model"). That reads like preparation for a default-model change.
• MCP governance: Peter Alexander (Core Maintainer; leads the Skills-over-MCP and Tasks/Events WGs) changed GitHub handle from @pja-ant to @poita, and the "Anthropic" affiliation was removed from both WG rosters.
• Noise: about 50 support articles changed only because their Intercom image URLs were re-signed. Managed-agents quickstart READMEs got version bumps.
