As of now, LangChain has an ad hoc release process: releases are cut with high frequency by a maintainer and published to PyPI. The different packages are versioned slightly differently.
langchain-core
langchain-core is currently on version 0.1.x.
As langchain-core contains the base abstractions and runtime for the whole LangChain ecosystem, we will communicate any breaking changes with advance notice and version bumps. The exception for this is anything marked with the beta decorator (you can see this in the API reference and will see warnings when using such functionality). The reason for beta features is that given the rate of change of the field, being able to move quickly is still a priority.
