Released version 2.12.0

Tracy learns to speak AI. This release turns every error screen, debug bar, and dump() call into a first-class citizen of agentic workflows – when an AI coding assistant hits your app, it gets a structured, token-efficient view of exactly what went wrong instead of a blob of HTML. Plus the usual spit-and-polish: a unified "transparent frames" model across BlueScreen and Dumper, a new breadcrumb in logged exceptions showing where Debugger::log() was called from, and a few quality-of-life API additions.

✨ New Features

• AI agent support – Tracy now detects AI agents (via Helpers::isAgent()) and serves them tailored output instead of HTML:
  • BlueScreen renders a dedicated agent template for exceptions, making stack traces and context machine-readable
  • Debug Bar ships an agent-friendly render path with bespoke templates for the Warnings and Dumps panels
  • Debugger::dump() writes to the console when an agent is on the other end, so your dumps land where the agent actually looks
  • Production error page now includes a hint for agents so they don't have to guess what happened behind the generic 500
• Markdown companion files – every HTML error log now gets a .md sibling, giving agents a clean, readable version of the same crash
• Debugger::$transparentPaths – a public, autodetected list of "framework" paths (Tracy, Nette, Latte) whose frames are skipped when locating the real call site. Path-based, so it catches anonymous functions and closures that class-based detection missed
• Helpers::findCallerLocation() – walks the backtrace and returns the first frame outside $transparentPaths, respecting @tracySkipLocation and internal functions. Reusable across Tracy instead of buried in Dumper
• Helpers::countTransparentFrames() – companion helper returning the number of leading transparent frames in a trace
• Logger records caller location – exception reports now show a "Logged from ..." footer pointing to the exact line where Debugger::log() was called, alongside the existing "Report generated at" entry
• Dumper::toText() – gained an optional $key parameter so you can label the dumped value in text output

♻️ Code Refactoring

• BlueScreen stack-trace collapse unified with Debugger::$transparentPaths – one source of truth for which frames to hide, replacing the inline logic in section-stack-exception.php. BlueScreen::$collapsePaths and isCollapsed() remain as @deprecated shims so existing configuration keeps working
• BlueScreen internals cleaned up, including a new prepareStack(\Throwable) method that strips Tracy's own handler frames and returns the frame index to expand by default

Released version 2.11.4

A maintenance release focused on CSP-friendly assets, mobile-friendly error pages, and a couple of handy API additions. Expect cleaner nonce handling, better behavior on phones, and a bar.js that no longer trips strict Content Security Policies.

• script-src-elem support in Helpers::getNonce() – nonces are now also picked up from the script-src-elem CSP directive, not just script-src (#612).
• CSP-friendly Tracy Bar – replaced the inline onload attribute in bar.js with a native addEventListener, eliminating a common CSP violation (#614).
• FileSession::clean() – emits a warning when the session directory is not readable, making misconfigured storage easier to diagnose (#538).
• Mobile-friendly error pages – BlueScreen and the 500 error template now include a proper viewport meta tag, so exceptions no longer render microscopically on phones (#604).
• Improved PHPDoc descriptions and fixed PHPStan errors across the codebase.
• open-in-editor on Windows – installer now registers the protocol via AutoLaunchProtocolsFromOrigins, suppressing the browser's "Open external app?" confirmation prompt (#573).

Released version 2.11.3

• Templates converted to Latte-like syntax, paving the way for a cleaner templating pipeline
• Environment guards relocated from Debugger to the individual strategy classes, improving separation of concerns
• Upgraded to PHPStan level 8 — the strictest static analysis level is now passing

Released version 2.11.1

✨ New Features

• Dumper – added support for uninitialized lazy objects (PHP 8.4), displaying them with a (lazy) label and showing only pre-initialized properties
• Source mapper – added column support, so BlueScreen can now pinpoint the exact character position in mapped source files

🐛 Bug Fixes

• keysToHide now applies to bdump()/barDump() as well – previously sensitive keys were only hidden in dump() and BlueScreen (#608)
• TracyExtension sets keysToHide config for Debugger too, not just for BlueScreen (#608)
• Dumper correctly loads its assets even when $showBar = false (#606)
