Changelog

Track all updates, improvements, and fixes to Owl Browser.

v1.1.1

Latest April 15, 2026

Multi-Process Architecture & UUID Context IDs

3 changes

• Multi-process browser architecture: multiple browser processes run in parallel, each handling its own set of contexts. This enables higher throughput for concurrent automation workloads by distributing contexts across separate CEF instances.
• Context IDs now use a UUID-based format (timestamp + sequence + random) instead of sequential counters. This eliminates ID collisions in multi-process mode and removes the practical limit on context creation in long-running automations.
• Open-source detection benchmarks published at github.com/Olib-AI/owl-detection-report. Includes stealth, performance, and concurrency test results run against real-world detection services, with full methodology and reproducible scripts.
