stagehand-python@4.2.1: Release Stagehand packages ( 3160)
Browserbase Stagehand released patch updates across its ecosystem, enabling support for arbitrary new model IDs on supported providers without requiring package updates.
Why this signal matters
The automated Changesets release for Stagehand packages—including @browserbasehq/stagehand-python@4.2.1, @browserbasehq/stagehand@4.2.1, @browserbasehq/stagehand-go@4.2.1, and associated SDKs—introduces patch changes allowing supported providers to accept new model IDs without necessitating a library release. Stagehand will reject empty or whitespace-containing model IDs and will rely on individual providers to validate and report model availability.
Actionable summary
Stagehand packages (including stagehand-python@4.2.1 and stagehand@4.2.1) now dynamically accept new model IDs for supported providers, delegating availability checks directly to the providers while strictly rejecting empty or whitespace-containing IDs.
