What's New
HTTP Client Collector
This release adds a new collector that tracks HTTP client requests made through Laravel's HTTP client. The collector provides visibility into outbound API calls, making it easier to debug external service integrations and monitor response times.
Inertia Collector
For applications using Inertia.js, the new Inertia collector tracks shared data and props passed to Inertia components. This helps debug data flow in Inertia-powered applications.
Enhanced Livewire Support
The debugbar now includes improved component detection for Livewire versions 2, 3, and 4. This provides better visibility into Livewire component lifecycle events and data updates across all currently supported Livewire versions.
Laravel Octane Compatibility
This version includes better handling for Laravel Octane and other long-running server processes. The debugbar now properly manages state across requests in persistent application environments.
Cache Usage Estimation
The cache widget now displays estimated byte usage, giving developers better insight into cache memory consumption during request processing.
Debugbar Position and Themes
This version has many UI improvements and settings like debugbar position, auto-hiding empty collectors, themes (Dark, Light, Auto), and more:
