DeepSeek-V4 The DeepSeek API now supports V4-Pro and V4-Flash, available via both the OpenAI ChatCompletions interface and the Anthropic interface. To access the new models, the base_url remains unchanged, and the model parameter should be set to deepseek-v4-pro or deepseek-v4-flash . The two legacy API model names, deepseek-chat and deepseek-reasoner , will be discontinued in three months (2026-07-24). During the current period, these two model names point to the non-thinking mode and thinking mode of deepseek-v4-flash , respectively. For more details, please refer to this documentation .
Action requiredReview affected integrations and migrate before the documented retirement boundary.
## What's changed - Added to the Claude apps gateway: with `pricing:` set in `gateway.yaml`, signed-in Claude Code clients receive the same rates through managed settings, so `/cost` and telemetry match the spend meter - Added a startup warning for gateways when `access_control.allow_cidrs` is empty, and a one-time warning the first time a request arrives from a public address - Added the `gatewayInternalNetworks` managed setting, letting administrators allow `/login` to a Claude apps gateway on their organization's own public IPv4 block - Added `claude self-hosted-runner --remove-session-state` (default off): delete each session's per-session directories under ` /_sessions/` when the session ends - Added `configDirectory` to the output of `claude auth status --json` - Added `--json` to `claude plugin install`, `uninstall`, `update`, `enable` and `disable`, and `errorDetails`/`noteDetails` to each row of `claude plugin list --json` - Added browser-tab icons for published artifacts, chosen by Claude to match each page - Fixed every turn failing with HTTP 400 on third-party Anthropic-compatible endpoints (`ANTHROPIC_BASE_URL`) since 2.1.265: a regex in the Artifact tool's input schem
## What's changed - Cost estimates (`/cost`, status line, `--max-budget-usd`) now include the 1.1× US-only-inference premium for data-residency workspaces - Added the one-time fullscreen renderer offer on Bedrock, Vertex, Foundry and other previously excluded setups; new installs there now start in fullscreen - Added `/claude-api upgrade` to migrate Python projects from `anthropic` 0.x to 1.x, and updated the skill's Python reference for 1.x (timeouts use `anthropic.Timeout`, not `httpx.Timeout`) - Cloud sessions: plugins synced from claude.ai now show as `name@synced`, work with `claude plugin enable/disable @synced`, and never override a same-named plugin you installed - Alpine/musl builds: native image paste, clipboard, and audio-capture add-ons now load (musl-built binaries instead of glibc ones refused by the runtime) - The usage-limit message shown when your monthly spend limit is already used up now also says when your session or weekly limit resets - Fixed Bedrock streaming behind proxies that strip the response Content-Type header, which silently doubled billed API calls by re-running every turn non-streaming - Fixed Claude Code hanging at startup behind an HTTPS proxy whe
## What's changed - Fixed a 2.1.265 regression affecting LLM-gateway and proxy setups: the undocumented `CLAUDE_CODE_USE_GATEWAY` environment variable, previously ignored unless `ANTHROPIC_BASE_URL` and `ANTHROPIC_AUTH_TOKEN` were both set, began forcing Cloud-gateway sign-in on its own in 2.1.265, so configurations that set it alongside an API key, `apiKeyHelper`, or custom auth headers failed every request with "Not signed in to the Cloud gateway". The variable on its own is ignored again; no configuration change is needed
April 16, 2026 Claude Opus 4.7 launch Our latest model, Claude Opus 4.7, is now generally available. Opus 4.7 shows improvements in software engineering and complex, long-running coding tasks, as well as better vision, allowing it to see images in higher resolution. For more information, see our blog post: Introducing Claude Opus 4.7 .
## What's changed - Fixed every request failing with `400 … Input tag 'advisor_20260301'` when `ANTHROPIC_BASE_URL` points at a proxy or gateway (2.1.275 regression)
## What's changed - Added `--restricted` (or `CLAUDE_CODE_RESTRICTED=1`): removes the built-in tools that run commands or code and `WebFetch` (unless named in `--tools`), keeps file tools inside the working directory, refuses `bypassPermissions`, and ignores user, project and local settings files - Added `experimental.cacheTtl` (`"5m"` or `"1h"`) to agent frontmatter: a per-agent prompt cache TTL used when no subagent TTL setting is configured - Added `claude self-hosted-runner --client-label ` (or `SELF_HOSTED_RUNNER_CLIENT_LABEL`) to override the label the runner registers with (default: hostname) - Added server-managed settings diagnostics: a startup warning when the settings fail to load, and a `/doctor` and `/status` line explaining a load failure or why they weren't fetched (Bedrock/Vertex/third-party provider, custom `ANTHROPIC_BASE_URL`) - Added a warning in `/web-setup` when the GitHub CLI token lacks the `workflow` scope, since pushes to very large repositories can be rejected without it - Added `/usage-credits` for Enterprise organizations billed through AWS Marketplace, self-serve Enterprise, and Enterprise trials, so members can request a higher usage limit from their
