🚀 BotBrowser 2025-01-24

This release introduces a groundbreaking GPU emulation feature for headless servers, alongside new fingerprinting capabilities to maintain seamless compatibility with GPU-sensitive antifraud systems.

✨ Major Upgrade

• GPU Emulation on Headless Servers: BotBrowser can now fully emulate GPU-related fingerprints on devices without dedicated GPUs, including navigator.gpu, GPUAdapter, GPUAdapterInfo, GPUDevice, WebGLRenderingContext, and WebGL2RenderingContext.
  • Perfect for VPS servers (Linux, Windows) without GPUs, eliminating the need for costly GPU rentals.
  • Successfully bypasses GPU-sensitive antifraud systems, such as the latest hCaptcha updates, which began fingerprinting navigator.gpu.

🛠️ New Additions

• GPUAdapterInfo and WGSLLanguageFeatures Fingerprinting: Added support for these advanced GPU-related fingerprints, further enhancing compatibility and detection resistance.

📄 For the full list of changes, please see CHANGELOG.md.
