Microsoft has rolled out Visual Studio Code version 1.113, bringing a wave of updates focused on personalization and deeper AI integration. The new release, available since March 25 for Windows, macOS, and Linux, puts an emphasis on features like a unified chat customizations editor, broader Model Context Protocol (MCP) support, and enhanced agent collaboration.
With Microsoft now publishing weekly updates, VS Code 1.113 follows closely behind its predecessors 1.111 and 1.112. This faster cadence ensures developers get new tools and fixes more rapidly than under the previous monthly schedule.
One of the standout additions is the preview of the Chat Customizations Editor, a centralized interface that allows developers to create, organize, and refine chat behaviors without leaving the editor. This new panel divides customization categories—such as prompts, custom instructions, and agent skills—into separate tabs. It even embeds a syntax-aware code editor with automatic validation. Users can either write customizations manually or use AI assistance to suggest base content tailored to their current project.
Another notable upgrade is improved Model Context Protocol (MCP) connectivity. MCP servers set up in VS Code now communicate seamlessly with Copilot CLI and Claude agents, whether they’re user-defined or configured through mcp.json files. Previously, such servers were limited to the local editor environment. Microsoft has also refined support for Claude sessions, switching to the official SDK API to list sessions and messages—preventing past synchronization errors caused by outdated JSON parsing.
Additional highlights in VS Code 1.113 include:
Subagents can now call other subagents, making it possible to orchestrate multi-step or nested workflows while maintaining recursion safeguards.
The chat system now supports a full-size image viewer. Users can open attachments or AI-generated visuals directly in a dedicated preview pane.
Reasoning models like Claude Sonnet 4.6 and GPT‑5.4 gain a new Thinking Effort submenu in the model selector, letting developers adjust reasoning depth on the fly.
Browser tab handling across workspaces has been polished for better organization and performance.
VS Code introduces two redesigned default themes—VS Code Light and VS Code Dark—refreshing the look and feel while keeping the familiar usability of the older “Modern” options.
Altogether, version 1.113 shows Microsoft’s continuing investment in merging traditional development tools with AI workflows, giving developers greater control, adaptability, and visual consistency in daily coding sessions.
