* Task: treat DO-NOT-KNOW as invalid answer * ChatDocument.from_LLMResponse: set LLM response '""' or "''" -> ''
0.1.167
* LLMMessage now has a timestamp field that auto-populates with the creation time. This means the messages in a ChatAgent's `message_history` will have timestamps, which can have various uses (e.g. you could store these in a DB and filter by recency etc). * minor fix in async OpenAI call (use async retry instead of retry)
0.1.166
* [Neo4jChatAgent](https://github.com/langroid/langroid/tree/main/langroid/agent/special/neo4j) to chat with a neo4j knowledge-graph. The agent translates user queries to Cypher queries and the queries are run against an existing, specific knowledge-graph. See [example script](https://github.com/langroid/langroid/tree/main/examples/kg-chat) * Support for .doc file parsing (in addition to .docx)
0.1.165
Update with recent changes to azure, aiohttp dependency
0.1.164
Minor fix: Agent.base - _get_one_tool_message - handle case when request is not a str
0.1.163
User conveniences: * Ignore bad OPENAI_API_KEY when user is specifying a non-OpenAI model * DocChatAgentConfig - no need to specify RelevanceExtractorAgentConfig.llm: if not specified, it will inherit LLM config from DocChatAgentConfig. But of course one could specify these to use two different LLMs.
