5 articlesClaude Code changelog
Release notes for Claude Code, including new features, improvements, and bug fixes by version. This page is generated from the CHANGELOG.md on GitHub. Run `claude --version` to check your installed version. * Added GitLab merge request URL support to the `--worktree` flag and the `claude agents` view (where MRs display as `!N`) * Added an opt-in `forward_user_identity` apps gateway setting on Anthropic upstreams that sends the signed-in user's identity as headers, so a proxy behind the gateway can attribute spend per user * Added opt-in memory cgroup support for Bash tool commands on Linux (`CLAUDE_CODE_TOOL_MEMORY_LIMIT`) so a runaway build can't stall the session * Added `CLAUDE_CODE_WEBFETCH_CACHE_TTL_MS` environment variable to configure the WebFetch session URL cache TTL (default…
Configure permissions
Control how your agent uses tools with permission modes, hooks, and declarative allow/deny rules. The Claude Agent SDK provides permission controls to manage how Claude uses tools. Use permission modes and rules to define what's allowed automatically, and the `canUseTool` callback to handle everything else at runtime. When Claude requests a tool, the SDK checks permissions in this order: Run hooks first. A hook can deny the call outright or pass it on. A hook that returns `allow` does not skip the deny and ask rules below; those are evaluated regardless of the hook result. Check `deny` rules (from `disallowed_tools` and settings.json). If a deny rule matches, the tool is blocked, even in `bypassPermissions` mode. Bare-name deny rules like `Bash` remove the tool from Claude's context…
Claude Text Watermark
Future Claude models will generate text that contains a watermark. This is a way of determining the likelihood that Claude was involved in writing the text, and we, along with several other major AI providers, are implementing this change to comply with the EU AI Act. In this article, we share answers to some of the questions we’ve received about how our chosen watermarking method works, whether it affects Claude’s outputs, and why we’re making this change.
How Claude Code works
Understand the agentic loop, built-in tools, and how Claude Code interacts with your project. Claude Code is an agentic assistant that runs in your terminal. While it excels at coding, it can help with anything you can do from the command line: writing docs, running builds, searching files, researching topics, and more. This guide covers the core architecture, built-in capabilities, and tips for working effectively. For step-by-step walkthroughs, see Common workflows. For extensibility features like skills, MCP, and hooks, see Extend Claude Code. When you give Claude a task, it works through three phases: **gather context**, **take action**, and **verify results**. These phases blend together. Claude uses tools throughout, whether searching files to understand your code, editing to make…
Monitoring
Learn how to enable and configure OpenTelemetry for Claude Code. Track Claude Code usage, costs, and tool activity across your organization by exporting telemetry data through OpenTelemetry (OTel). Claude Code exports metrics as time series data via the standard metrics protocol, events via the logs/events protocol, and optionally distributed traces via the traces protocol. Configure OpenTelemetry using environment variables: export CLAUDE_CODE_ENABLE_TELEMETRY=1 export OTEL_METRICS_EXPORTER=otlp # Options: otlp, prometheus, console, none export OTEL_LOGS_EXPORTER=otlp # Options: otlp, console, none export OTEL_EXPORTER_OTLP_PROTOCOL=grpc export OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:4317 export OTEL_EXPORTER_OTLP_HEADERS="Authorization=Bearer your-token" export…

An A.I. Bot is Judging Your Résumé
Raise your hand if you’ve been personally victimized by an A.I. job recruiter. Finding a job has become more difficult in part because many corporations are now using bots to evaluate résumés. The Opinion writer Jessica Grose explains why job hunting has become about gaming A.I. recruiters, and why the solution might just be going analog.

Suspecting court of using AI, man injected prompts in filings to try to win case
A judge has identified what appears to be the first time a US plaintiff has attempted to hide text in court filings that only an artificial intelligence system can read in a bid to win a case. In a decision published last week, Connecticut judge Walter Spader Jr. confirmed that the hidden text had no impact in a case where a man alleged a healthcare provider was improperly withholding access to records. The court weighed his filing on the merits, Spader said, but nevertheless, the attempted attack sets a “dangerous” precedent. This will likely not be the last time US courts see the malicious tactic, as AI tools become more commonplace in court systems. Trying to scramble any AI systems potentially influencing the court’s reading of his filing, the secret instructions were “formatted to be…
Mark Zuckerberg has an Instagzam
Instagram's wordmark is iconic. Well, was iconic. Apparently Instagram thought it looked old, so the company rolled out a new one this week. It doesn't look like the old Instagram wordmark. It doesn't even look like it spells Instagram anymore. And we cannot figure out why Instagram decided to do this. On this episode of The Vergecast , David and Nilay start by discussing the new logo, the executive urge to redesign everything all the time, and whether new is always better. After that, they get into the other big Meta release of the week: Mark Zuckerberg's many-thousand-word missive on the future of AI. There are a lot of ideas and proposals … Read the full story at The Verge.
You can now turn off Google Gemini’s visible watermarks
Google will now allow you to remove visible watermarks from the images, videos, and music made with AI tools. With the update , you can toggle off a new "Media watermark" setting in Gemini and Google's AI video generator, Flow. When toggled off, Google will remove the "sparkle" watermark that appears in the bottom-right corner of content generated with the company's Nano Banana and Omni models. Though visible watermarks are now optional, AI-generated content will have invisible SynthID watermarks and C2PA metadata embedded in the background, according to Josh Woodward , the vice president of Google Labs, Gemini, and AI Studio. That means you … Read the full story at The Verge.

OpenAI and Anthropic in price war as Chinese AI rivals gain ground
Leading US AI labs such as OpenAI and Anthropic are releasing cheaper models as they fight to retain cost-conscious customers who are switching to cut-price alternatives from Chinese rivals. The price war comes as rising AI bills push companies to curb usage and seek cheaper models, helping Chinese developers including Moonshot and DeepSeek make inroads with users from Silicon Valley to Europe. OpenAI recently said that it was slashing prices for GPT-5.6 Luna, its “fastest and most affordable model”, by 80 percent. Anthropic has launched Claude Opus 5, touting the system’s “frontier intelligence... at half the price” of Fable 5, the company’s most capable model. Read full article Comments

Apple trained its own AI model for China with help from Alibaba
Apple has reportedly trained a custom AI model for the China market alongside domestic tech giant Alibaba, a rare cross-border partnership that cuts across growing tensions between Beijing and Washington. The China-focused large language model was developed in partnership with Alibaba and trained with the company's support, Reuters reports , citing three unnamed people familiar with the matter. Developing a custom model of its own marks a departure from Apple's previous strategy in the country and would give the company more control over its products in the competitive Chinese smartphone market. Historically, Apple has used domestic Chines … Read the full story at The Verge.
