LangChain core 1.2.19 is released with changes since 1.2.18, referencing pull request #35832.
A chore moves BaseCrossEncoder to langchain-core, reflecting an architectural reorganization (PR #35809).
The core library bumps Tornado from 6.5.2 to 6.5.5 (PR #35775).
The update appears to be a minor maintenance release focused on internal structure and dependencies rather than introducing new user features.
