PhpStorm 2026.3 adds an agent workspace and PHP 8.6 support
Air puts agent sessions, files and diffs side by side in editor tabs. It works with Claude Agent, Codex, Gemini, Copilot, Junie and other ACP-compatible agents.
JetBrains shipped PhpStorm 2026.3 on 6 November. The headline addition is Air, a new agentic workspace built into the IDE: agent sessions, project files and diffs open side by side in editor tabs, and it works with Claude Agent, Codex, Gemini, GitHub Copilot, Junie, OpenCode and other ACP-compatible agents.
PHP 8.6 lands later this month, and this release already supports it, with migration inspections, quick-fixes for 8.6-only syntax, and an “Initialize property in constructor” fix for readonly properties with default values. Git worktrees now copy your local .idea configuration, including run configurations, so opening a pull request in its own worktree no longer means losing your setup. JetBrains also moved several blocking operations off the UI thread, fixing reported freezes in Composer projects, deployment connections and Twig debugging.
For Laravel specifically, there are new inspections for unknown config keys, missing resource route methods and unknown Livewire components, plus a Processes tab for managing queue workers and dev servers, and the terminal has been rebuilt on the libghostty library.
Why it matters: if you already live in PhpStorm, this is the release where agent coding stops being a separate browser tab or terminal window and becomes part of the IDE’s own tooling, alongside real PHP 8.6 readiness ahead of its general release.
