TL;DR

This release introduces a new API for managing browser extensions, allowing them to be uploaded, managed, and attached to browser sessions at creation.

Why we made these changes

This feature enables users to programmatically control the extensions loaded into a browser. This is critical for scenarios like testing browser extensions, web scraping with specific extension-based tools, or creating customized browsing environments for automation tasks.

What changed?

• New Extensions API:
  • Added a new client.extensions resource with methods to list, delete, download, upload, and download_from_chrome_store.
  • Introduced corresponding request and response types (e.g., ExtensionUploadParams, ExtensionListResponse).
• Browser Integration:
  • Added client.browsers.upload_extensions to upload extensions directly to a specific browser instance.
  • Updated BrowserCreateParams to allow specifying a list of extensions to install when a new browser is created.
• Documentation & Versioning:
  • Updated api.md to document the new extensions API.
  • Bumped the package version to 0.14.0 in pyproject.toml, CHANGELOG.md, and other metadata files.

Validation

• Added a new test suite in tests/api_resources/test_extensions.py to cover the lifecycle of extensions (upload, list, delete).
• Updated tests in tests/api_resources/test_browsers.py to verify that extensions can be correctly attached to new browser sessions.

Analysis

While this PR adds comprehensive browser extension functionality to the Kernel Python SDK following established patterns, potential architectural issues include:

1. Potential complexity in handling OS-specific packaging for Chrome Web Store extensions that may introduce platform-specific bugs
2. Possible performance concerns with multipart uploads of large extension ZIP files
3. Risk of tight coupling between the new Extensions API and the existing browsers API, which could complicate future changes
4. Security considerations around extension validation and sandboxing may be incomplete
