TL;DR

This is a maintenance and feature release that introduces a new proxies resource, refactors optional parameter handling for improved type safety, and updates core dependencies like Pydantic.

Why we made these changes

The primary goal was to enhance the SDK's capabilities by adding support for proxies. Additionally, we took the opportunity to improve internal code quality by standardizing how optional parameters are handled, moving from a class-based NotGiven sentinel to a more explicit not_given singleton and a new omit value. This release also includes dependency updates to ensure compatibility and security, notably with Pydantic v2.

What changed?

• Feature: Added Proxy Resources
  • Introduced kernel.proxies with create, retrieve, and list methods.
  • Added an optional proxy_id to the browsers.create method to associate a browser with a proxy.
• Refactor: Optional Parameter Handling
  • Replaced the NOT_GIVEN sentinel with a singleton instance not_given throughout the client for consistency.
  • Introduced a new omit sentinel to explicitly exclude optional parameters from API requests.
  • Updated internal utilities (is_given, _transform_typeddict) to correctly handle not_given and omit.
• Dependencies & Tooling
  • Upgraded Pydantic and updated _models.py to be compatible with Pydantic v2.
  • Modified the scripts/bootstrap script to make Homebrew dependency installation interactive and optional.
  • Added a new CI workflow for Stainless.

Changing the default value of by_alias from False to None could introduce breaking changes for users who rely on keyword argument introspection or who expect the parameter to always be a boolean. Consider maintaining backward compatibility by keeping the default as False while still allowing None to be passed explicitly.
