Stay up to date with the latest developer tools news, updates, and releases. Everything worth knowing, curated and delivered fresh today.
Full-stack Engineer
If you've ever opened your IDE on a Monday morning and found that half your workflow just changed, you know how quickly the developer tools landscape moves. A new Copilot update, a VS Code release you didn't know about, or a Google I/O announcement can completely alter your approach to development. Staying updated isn’t optional anymore. Missing a major update can result in your team debugging issues that have already been fixed, or overlooking a feature that could reduce your PR turnaround time significantly. Here’s everything that truly matters in developer tools right now, based on the latest releases and announcements.
Visual Studio Code 1.129: The Agent Host Era Begins
Released on July 15, 2026, VS Code 1.129 is arguably the most important release the editor has seen in years. The main change isn't a flashy new UI; it's a structural one.
Agent sessions now run in a dedicated agent host process, completely separate from your editor. This means that you can connect to the same agent session from multiple VS Code windows at the same time. Plus, a crashing agent no longer brings your editor down with it. For teams running long-term autonomous tasks, this is a major improvement.
A few other notable additions in this release:
- ! prefix for terminal commands: You can now type
!npm run builddirectly in a chat prompt to run commands from within agent conversations. No more context-switching between chat and the integrated terminal.
- New editor panel in the Agents window (Experimental): Agent-generated files and diffs now appear in a docked editor panel. You can review the work without leaving the Agents window.
- Modern UI preview: A first look at VS Code's updated workbench appearance is available in experimental mode. It's not the default yet, but you can turn it on to see where the editor is going visually.
The 1.127 and 1.128 releases from earlier this month are also important. The browser tools for agents, which allow Copilot to navigate pages, take screenshots, and click through to check its own web app output, are now generally available and enabled by default. Per-site browser permissions have replaced the old global toggle. This change means you can now give camera or location access to one site without granting it for all sites. Copilot Vision, which allows users to attach images and PDFs directly to chat, is also now available across all Copilot tiers, including Free.
GitHub Copilot : What Changed This Month
The pace of Copilot updates in July 2026 has been relentless. Here's what's shipping right now:
- Kimi K2.7 Code is now available in GitHub Copilot's model picker. This is the first open-weight model you can choose in Copilot, offering developers a meaningful alternative to proprietary models. If you have been looking for an open model option in your main coding tool, this is it.
- Copilot Vision is available for everyone, with no need for admin policy changes. Previously, Business and Enterprise users needed the Editor Preview Features policy enabled at the organization level. That barrier is now removed. All Copilot plans (Free, Pro, Pro+, Business, Enterprise) can now attach images and PDFs to chat prompts.
- Copilot CLI now features smarter auto model selection. The CLI automatically routes your task to different models based on what you are doing. Simple queries do not use the same compute budget as complex multi-step agent tasks. You can also configure session-level AI credit limits through both the CLI and SDK, which is important for teams that require cost management on autonomous agent work.
- Copilot repository overviews are live for first-time visitors. When you visit a repo you have not contributed to before, Copilot will offer to create a summary of its purpose, tech stack, and contribution guidelines. It can even draft a README if one is missing. This feature is available on all Copilot plans.
- GitHub Code Quality will become a paid product on July 20, 2026, with a cost of $10 per active committer per month. If you are using it in preview on GitHub Enterprise Cloud or Team, check your active committer count in Billing and Licensing before billing begins.
- GitHub Models will be retired on July 30, 2026. It closed to new customers in June. If your workflow relies on the GitHub Models endpoint, you should start planning your migration now.
One more thing: Secret scanning now runs validity checks on Asana, IBM, and MessageBird secrets. This lets you quickly see if a leaked credential is still active or has already been rotated.
Visual Studio 2026: July Update — "A New Era" for the IDE
Microsoft released the Visual Studio 2026 July update on July 14, 2026 , with a statement that stands out: this release marks "the beginning of a new era for Visual Studio with deep platform integration of AI, stronger fundamentals, and improved performance."
The most practical addition in the July update is built-in .NET and Azure skills for the Copilot agent. Experts from the .NET and Azure teams created these skills, and they are available directly in the tool picker when you install the corresponding workloads. You can hover over each skill to view its description and file path. Use the three-dot menu to open or locate the skill file.
MCP server trust validation is now enabled by default. Visual Studio checks an MCP server's configuration and asset fingerprint against a trusted baseline at startup. If anything has changed since your last approval, a trust dialog will block the server from running until you review and approve it. This adds meaningful security as MCP-connected tools become more common in team environments.
Copilot usage tracking in Visual Studio now reflects GitHub Copilot’s usage-based billing model with real-time updates. You will receive proactive alerts when you are nearing your limit, when you have reached it, and when overages activate. You can also set the warning threshold manually in the settings.
Recent VS 2026 updates also include the ability to add pull requests directly to Copilot Chat for context, in-IDE pull request reviews without leaving Visual Studio, Copilot code reviews of individual commits (not just uncommitted changes), and an improved model picker that shows pinning, cost information, and context window sizes for each model.
Microsoft Build 2026 Recap: What It Means for Your Toolchain
If you missed Build in June, here's the condensed version of what matters for daily development work:
The Microsoft Agent Framework reached several milestones. Multi-agent Handoff orchestration achieved version 1.0 with explicit topology controls and guardrails. The GitHub Copilot SDK integration also reached version 1.0, supporting both .NET and Python. CodeAct support through Hyperlight cuts orchestration overhead by reducing many tool calls into fewer model turns. This is important for anyone building or running agents in production.
The Agent Control Specification (ACS), which was open-sourced at Build, is a portable, vendor-neutral specification for governing runtime agents. If you're developing multi-agent systems and are interested in who controls what, this specification is worth a look, no matter what tools you use.
.NET 11 was released with union types in C#, which is one of the most requested language features. It also offers strong support for agentic development patterns in ASP.NET Core and Blazor. For .NET developers, the AI Building Blocks guide that came out with it is a useful starting point for adding AI features to C# applications.
Fabric Data Warehouse with GPU acceleration has been tested to be up to 7 times faster than competing cloud warehouses in reporting, application, and AI-driven analytics scenarios. Query acceleration will enter early access preview in the coming weeks.
Google I/O 2026 : The Agentic Web Stack Arrives
Google's I/O developer keynote in May delivered a cluster of announcements that are now starting to ship. Here's where things stand:
Antigravity 2.0 is Google's rebranded and improved agent-first development platform. The new Antigravity CLI allows you to create specialized subagents for complex workflows with built-in terminal sandboxing, credential masking, and strict Git policies. If you are already using a Google-related stack, this is worth considering as an alternative to building your own agent orchestration.
WebMCP is a proposed open web standard that lets developers expose structured tools, such as JavaScript functions and HTML forms, so browser-based AI agents can perform complex tasks with more precision. An experimental origin trial starts in Chrome 149. This is something to monitor for front-end developers focused on agent-accessible interfaces.
Chrome DevTools for agents brings DevTools features to AI agents, improving verification, debugging, and optimization workflows. More practically, agents can now handle the debugging work themselves instead of you explaining what is in the console.
Android Studio has now fully entered the agent era. The stable Android CLI allows AI agents to use Android Studio features, like downloading the SDK and running your app on devices, from any agent, large language model, or toolchain you prefer. Android skills were open-sourced to help large language models follow best practices for complex workflows, such as Jetpack Compose migration and Jetpack Navigation 3 migration.
The HTML-in-Canvas API (origin trial) is a new Chrome feature that enables developers to create immersive, 3D canvas experiences where the content remains searchable, accessible, and interactable by integrating real DOM elements directly into a canvas using WebGL/WebGPU. It is still early, but it is interesting from an architectural standpoint for complex web app user interfaces.
WordPress for Developers: July 2026 Updates
For developers working in the WordPress ecosystem, the July 2026 developer update covers the 7.1 beta cycle and several practical tooling changes.
WordPress 7.0.1 was released on July 9 with 13 Core tickets and 13 Gutenberg fixes, all focused on fixing bugs. Gutenberg 23.5, released on July 1, raises the minimum required WordPress version to 6.9. Check your development and staging environments before updating.
WordPress Studio 1.11.0 added Studio Code, a development tool for WordPress.com, to the desktop app. The beta is free to use during this phase with a WordPress.com account.
WordPress Playground now supports MCP and features a
playground_ability meta-tool. Instead of exposing one MCP tool for each registered ability, agents can now list, inspect, and execute all Playground abilities through a single unified tool. This makes agent-driven development workflows much cleaner.WordPress 7.1 Beta 1 will be available on July 15, with subsequent betas released weekly through the end of July. The final version is scheduled for August 19, 2026, in line with WordCamp US.
Slack Developer Tools : Real-Time Search API & MCP Server
Slack's developer tools received a significant infrastructure update with the launch of the Slack MCP Server and the Real-Time Search (RTS) API at the same time.
The MCP server is made for LLM use. It provides natural language responses and includes descriptions and examples for agent interaction, not just API use. This is the Slack integration to choose when building agents that need to read and act on workspace data.
The Real-Time Search API evolved from the older Data Access API. It allows third-party applications to get relevant Slack data through a secure search interface without storing customer information on outside servers. Together, these features fill a major gap in Slack's developer ecosystem for AI-powered applications.
The deprecation of classic Slack apps has been delayed again, now set for November 2026. If you’re still using a classic app and have not migrated yet, this is your last chance to plan and make the switch without feeling rushed.
TypeScript 7: Native Speed, Real Impact
TypeScript 7 was announced on July 8, 2026, as a joint effort between the VS Code and TypeScript teams. The main focus was on improving Go performance. The language service for TypeScript 7 has been completely rewritten to operate as a native binary. This change cuts down the time needed for type checking and IntelliSense responses in large codebases.
VS Code started using TypeScript 7 internally and shared details about the collaboration in a blog post published on June 26. For projects where TypeScript type-checking delays have been an issue, this update significantly enhances the experience of working with the language.
Conclusion
The thread connecting everything mentioned isn't just about "AI features." It's a shift toward agentic development as the default mode. These are tools that don't just help on request; they can handle a task from specification to tested output with minimal guidance. VS Code 1.129's agent host, GitHub Copilot's session-level governance tools, Google's Antigravity CLI, Microsoft's Agent Framework hitting 1.0, and Android Studio's open CLI are not isolated features. They represent a coordinated shift in platforms.
The developers who benefit the most from this moment are those who understand what these tools actually do. It's not just about clicking "update" and hoping for the best. Read the changelogs. Test the agent behaviors in your own workflows. Stay skeptical enough to verify what the agent produces before you ship it.
The next wave of releases is already in Insiders and Canary builds. More is coming soon.
Frequently Asked Questions
Q: What is the latest version of Visual Studio Code?
VS Code 1.129, released on July 15, 2026, is the current stable version. It adds a dedicated agent host process that runs agent sessions separately from the editor, multi-window session connections, and a ! prefix for running terminal commands directly from chat prompts. The Insiders build (1.129+) is available for those who want features before they go stable.
Q: What is GitHub Copilot Vision?
GitHub Copilot Vision lets you attach images and PDFs directly to Copilot chat prompts. This allows Copilot to consider visual content along with your code. As of July 1, 2026, it became available to all Copilot subscribers, including Free, Pro, Pro+, Business, and Enterprise, with no changes needed in admin policies to enable it. You can attach files by pasting, dragging, or dropping them into the chat input in VS Code and other supported areas.
Q: What developer tools were announced at Microsoft Build 2026?
Microsoft Build 2026, which took place on June 2–3, announced multi-agent Handoff orchestration at version 1.0, the GitHub Copilot SDK at version 1.0 for .NET and Python, the open-source Agent Control Specification (ACS), CodeAct support through Hyperlight, .NET 11 with union types in C#, GPU-accelerated Fabric Data Warehouse, Azure HorizonDB, a new GitHub Copilot desktop app for directing parallel agents, and deep AI integration in Visual Studio 2026. The Build CLI tool connected the terminal directly to the Build session catalog for on-demand session discovery.
Q: What is the Model Context Protocol (MCP) and which tools support it?
MCP (Model Context Protocol) is an open standard that allows AI agents to interact with external tools and data sources in a structured and consistent way. In 2026, MCP support expanded significantly. Visual Studio now validates MCP server trust at startup. VS Code supports MCP OAuth credentials and workspace-scoped plugin management. The GitHub Copilot CLI supports live MCP server management during running sessions. WordPress Playground added MCP support, and Slack introduced a dedicated MCP server for workspace data. Google's WebMCP proposal broadens the idea to the open web, enabling browser-based agents to work with structured web tools.
Q: Is GitHub Models shutting down?
Yes. GitHub announced in June 2026 that GitHub Models is retiring. It is closing to new customers immediately and will fully shut down on July 30, 2026. If your project uses the GitHub Models API endpoint for model inference, you need to migrate before that date. GitHub Copilot's model picker, which now includes open-weight options like Kimi K2.7 Code, is the recommended replacement for most use cases.
