Breaking Changes

●Issue #1

Removal of Firefox CDP support across Java, JavaScript, Ruby, Python, and .NET may break code that relies on Firefox CDP APIs. Update code to use alternative mechanisms (e.g., BiDi) or remove CDP calls.

Migration Steps

  1. 1
    Remove or replace any usage of Firefox CDP APIs in Java, JavaScript, Ruby, Python, and .NET projects.
  2. 2
    If using BiDi `setCacheBehavior`, ensure the driver version supports the command.
  3. 3
    Update code that configures dead node service intervals to use the new configurable setting (Java).
  4. 4
    Adjust logging configuration to rely on Selenium logging options rather than Java logging defaults (Java).
  5. 5
    Review and update any code that depends on CDP deprecation warnings now suppressed when BiDi is enabled (Java).

Release Summary

This release adds several BiDi enhancements, improves page‑size handling, updates Grid UI, and introduces extensive nullability annotations, while removing Firefox CDP support which may require code changes.
