PydanticAI 2.54.0 adds OpenAI Live session recovery, GPT-Live WebSearchTool support and stronger agent-workspace safeguards

What changed

PydanticAI released 2.54.0 on October 3. OpenAILiveModel can now recover dropped sessions by forking a stored session or replaying history, GPT-Live gains delegated WebSearchTool support, and ExaSearch/YouSearch add a native mode that prefers a model’s built-in web search. The clai2 interface adds a double-Esc conversation rewind menu, while /update installs the newest build and restarts into the resumed session. The release also strengthens shell realpath fallbacks, LocalFileStore ownership checks and Bubblewrap/SSH workspace boundaries against symlink or shell-startup-file escapes.
