Anthropic has released version 2.1.0 of Claude Code. It is a substantial update to its development environment for vibe coding. With Claude Code, the company focuses on autonomous software development, controlling AI agents, and performing various computer tasks from the terminal.
Boris Cherny, responsible for Claude Code, reports to VentureBeat that the new release includes more than a thousand separate changes. The version emphasizes better control, reusability, and collaboration within complex development processes.
Claude Code is increasingly being used by developers for more than just generating individual code snippets. The system, based on Anthropic’s Claude model family, including the latest flagship Claude Opus 4.5, is used to set up long-term workflows in which multiple agents collaborate. This marks a shift from experimental use to structural deployment within development teams.
The tool was originally introduced in February 2025 as a command line solution, simultaneously with the Claude Sonnet 3.7 language model. Since then, Claude Code has been updated regularly, with new capabilities usually linked to improvements in the underlying models. With version 2.1.0, the focus is shifting emphatically to infrastructure and orchestration. Developers gain more control over how agents are started, controlled, and reused across different sessions and environments.
An important part of the update is the expansion of agent lifecycle management. Developers can now link logic to tool usage and agent termination both before and after the fact. This helps with status management, logging, and error analysis. In addition, skills can be modified directly without restarting sessions, which speeds up experimentation and iteration. It is also possible to run subagents in isolated contexts, allowing new logic to be tested without affecting the main workflow.
Better terminal experience
In terms of collaboration and scalability, Anthropic is introducing broader permission models for tools, support for language-specific output, and the ability to move sessions between local terminals and the web interface. This makes it easier to deploy Claude Code within international teams or to share work between different devices and developers. At the same time, the terminal experience has been refined with improved key combinations, more extensive Vim support, and faster rendering.
In addition to these structural changes, the release includes several improvements aimed at everyday use. These include smarter autocomplete, greater insight into agent progress, and better protection of sensitive data. Several security and stability issues have also been resolved, including the risk of confidential information ending up in debug logs.
The timing of this release is relevant. Claude Code is visibly gaining ground among experienced users who see AI not as an assistant, but as a programmable layer within their development process. For that group, version 2.1.0 explicitly positions Claude Code as a framework rather than a standalone model. The update does not redefine the product, but lowers the threshold for complex and repeated use.
Claude Code is available for paid Claude subscriptions, ranging from Pro to Enterprise. Some features require access to the web interface, while installation and documentation are available online.
