# 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.
