🔨 Improvements

• [CLI] Refactoring & Documentation: Browser CLI refactoring, bug fixes, and documentation improvements

🐛 Bug Fixes

• Tool Error Propagation: Fix tool errors (e.g., AgentRedirectError) not being propagated back to the model
• Async Tool Call Fix: Fix async TypeError when a tool call coroutine throws an exception, preventing serialization of an unawaited coroutine. Fixes #103
• [CLI] CSS Selector Fix: Fix CSS selector regex false positives where bare HTML tag names were incorrectly treated as CSS selectors
• [CLI] Log Capture Fix: Fix log_capture resource leak ensuring log.txt is created early in command execution
• [CLI] Install Command Fix: Fix pip install command in CLI README to properly quote nova-act[cli]
• [CLI] Starlette Compatibility: Fix Starlette 1.0.0 AttributeError in the AgentCore handler template by removing the redundant ping decorator

v3.3.96.0

🚀 What's New

• Browser CLI: Interact with Nova Act directly from the command line — browse, extract data, take screenshots, manage tabs, and control sessions without writing Python code
  • Attach to an already-running Chrome instance via --cdp, or launch your default Chrome with extensions using --use-default-chrome
  • Get structured JSON output (--json), minimal output (--quiet), or detailed logs (--verbose) to fit your scripting and debugging needs
  • Watch browser actions in real time with --observe for easier debugging and development
  • After each command, automatically capture an accessibility snapshot and screenshot so you always know the current page state
  • Auto-detects your authentication method (API key or AWS credentials) with options to configure via --auth-mode, --aws-profile, and --region
  • Browser sessions survive across CLI invocations with automatic recovery and metadata persistence
  • Run act browser doctor to check your environment or act browser setup for guided first-time configuration
  • Per-command log capture, per-step accessibility tracking, session recording, disk usage monitoring, and automatic failure screenshots
  • Generate Gherkin-based QA test plans from plain English descriptions using act browser qa-plan

v3.3.35.0

🚀 What's New

• Async Support (Preview): Async implementation of Nova Act for seamless integration with async applications and concurrent browser automation
• Trajectory Auto-Dump: Trajectory JSON files are now automatically saved to the session logs directory after each act call, replacing the previous call log format with standardized trajectory data including richer metadata
• Tool Call Results in Logs: Session log JSON and HTML reports now include tool call results for improved debugging visibility
• [CLI] Remote Workflow Visibility: CLI workflow list now fetches and merges remote AWS workflow definitions with local state, showing synced, remote, and local indicators with filter flags
• [CLI] ARM64 AgentCore Support: Docker builds now target ARM64 for AgentCore compatibility when deploying from x86_64 hosts

🔨 Improvements

• Tool Request Interception Bypass: Tools can now temporarily disable the SDK's request interception during execution, preventing browser freezes when external processes need to control the browser directly
• [CLI] Faster Startup: Heavy imports deferred to command execution time for snappier CLI response
• [CLI] Dynamic Dockerfile Region: Replace hardcoded region in Dockerfile with dynamic region resolution so deploys work in any region
• [CLI] Improved Error Messages: Exception chaining preserves full stacktraces for easier debugging

🐛 Bug Fixes

• Path Traversal Fix: Fix safe relative path handling to correctly handle edge cases where the path equals the base directory
• Color Input Events: Color picker inputs now correctly fire input and change events when values are set programmatically

v3.1.263.0

🚀 What's New

• Improved iFrame actuation: Improved handling of cross-origin elements for better dropdown interactions

🐛 Bug Fixes

• SSL stability: Fixed SSL hook deadlock by restricting unroute to interactive mode and improving context cleanup
• Security: Fixed path traversal vulnerability by validating S3 upload paths against base directory

v3.1.157.0

🚀 What's New

🐛 Bug Fixes

• String Response Parsing: Fixed issue where parsed string schema responses contained redundant double quotes.
• Dockerfile Improvements: Fixed Playwright installation in the CLI Dockerfile to ensure browsers are properly set up.

🔨 Improvements

• Logging Improvements: Trace logger is now a global singleton, making it easier for downstream applications to redirect and handle logs. Enhanced trace and log output provides more helpful debugging information.

v3.1.89.0

🚀 What's New

• Default Model Change: Updated default model to nova-act-preview when using API key authentication. Learn more in the AWS Documentation

🔨 Improvements

• Dependency Updates: Upgraded strands-agents and strands-agents-tools dependencies to include bug fixes, performance improvements, and enhanced functionality
