⚠️ Breaking Changes ⚠️
* Removed `memory.ConversationBufferWindowMemory` and `memory.ConversationBufferMemory`. They have been replaced with `memory.ChatMessageHistory`.

In order to keep up with the changes in upstream LangChain, we converted our Memory classes to a single `ChatMessageHistory` that may be used with the upstream conversational memory classes. This is a bit unfortunate, but should allow us to continue to stay in-step with the latest LangChain developments.

We apologize for the impact.
