Pavlo Paliychuk	342df7cf83	community[minor]: Add Zep Cloud components + docs + examples (#21671 ) Thank you for contributing to LangChain! - [x] PR title: community: Add Zep Cloud components + docs + examples - [x] PR message: We have recently released our new zep-cloud sdks that are compatible with Zep Cloud (not Zep Open Source). We have also maintained our Cloud version of langchain components (ChatMessageHistory, VectorStore) as part of our sdks. This PRs goal is to port these components to langchain community repo, and close the gap with the existing Zep Open Source components already present in community repo (added ZepCloudMemory,ZepCloudVectorStore,ZepCloudRetriever). Also added a ZepCloudChatMessageHistory components together with an expression language example ported from our repo. We have left the original open source components intact on purpose as to not introduce any breaking changes. - Issue: - - Dependencies: Added optional dependency of our new cloud sdk `zep-cloud` - Twitter handle: @paulpaliychuk51 - [x] Add tests and docs - [x] Lint and test: Run `make format`, `make lint` and `make test` from the root of the package(s) you've modified. See contribution guidelines for more: https://python.langchain.com/docs/contributing/ Additional guidelines: - Make sure optional dependencies are imported within a function. - Please do not add dependencies to pyproject.toml files (even optional ones) unless they are required for unit tests. - Most PRs should not touch more than one package. - Changes should be backwards compatible. - If you are adding something to community, do not re-import it in langchain.

Jan Soubusta	cccc8fbe2f	community[patch]: DuckDB VS - expose similarity, improve performance of from_texts (#20971 ) 3 fixes of DuckDB vector store: - unify defaults in constructor and from_texts (users no longer have to specify `vector_key`). - include search similarity into output metadata (fixes #20969) - significantly improve performance of `from_documents` Dependencies: added Pandas to speed up `from_documents`. I was thinking about CSV and JSON options, but I expect trouble loading JSON values this way and also CSV and JSON options require storing data to disk.

Leonid Ganeline	2416737c5f	docs: compact the API Reference links (#21285 ) This PR is opinionated. Issue: the `API Reference` sections in the examples hold too much vertical space and make us scroll the page too much. See an [example](https://python.langchain.com/docs/get_started/quickstart/#conversation-retrieval-chain). These sections are important. So, the compacting should not make these sections less noticeable. Change: compacting the `API Reference` sections. See the [same example after change applied](https://langchain-j6nya46lf-langchain.vercel.app/docs/get_started/quickstart/#conversation-retrieval-chain). It is more compact and now looks like references (footnotes). Note: I would also change the section style, so it would be more noticeable (maybe to look like the footnotes.

Robert Caulk	54adcd9e82	community[minor]: add AskNews retriever and AskNews tool (#21581 ) We add a tool and retriever for the [AskNews](https://asknews.app) platform with example notebooks.

The included notebook also includes deeper details about controlling filters such as category and time, as well as including the retriever in a chain. The tool is quite interesting, as it allows the agent to decide how to obtain the news by forming a query and deciding how far back in time to look for the news: ```py from langchain_community.tools.asknews import AskNewsSearch from langchain import hub from langchain.agents import AgentExecutor, create_openai_functions_agent from langchain_openai import ChatOpenAI tool = AskNewsSearch() instructions = """You are an assistant.""" base_prompt = hub.pull("langchain-ai/openai-functions-template") prompt = base_prompt.partial(instructions=instructions) llm = ChatOpenAI(temperature=0) asknews_tool = AskNewsSearch() tools = [asknews_tool] agent = create_openai_functions_agent(llm, tools, prompt) agent_executor = AgentExecutor( agent=agent, tools=tools, verbose=True, ) agent_executor.invoke({"input": "How is the tech sector being affected by fed policy?"}) ``` --------- Co-authored-by: Emre <e@emre.pm>	2 months ago

Leonid Ganeline	c4508ca7ef	docs: `arXiv` references page (#21450 ) Since the LangChain based on many research papers, the LC documentation has several references to the arXiv papers. It would be beneficial to create a single page with all referenced papers. PR: 1. Developed code to search the arXiv references in the LangChain Documentation and the LangChain code base. Those references are included in a newly generated documentation page. 2. Page is linked to the Docs menu. Controversial: 1. The `arxiv_references` page is automatically generated. But this generation now started only manually. It is not included in the doc generation scripts. The reason for this is simple. I don't want to mangle into the current documentation refactoring. If you think, we need to regenerate this page in each build, let me know. Note: This script has a dependency on the `arxiv` package. 2. The link for this page in the menu is not obvious. --------- Co-authored-by: Eugene Yurtsev <eyurtsev@gmail.com>	3 months ago

Stefano Lottini	040597e832	community: init signature revision for Cassandra LLM cache classes + small maintenance (#17765 ) This PR improves on the `CassandraCache` and `CassandraSemanticCache` classes, mainly in the constructor signature, and also introduces several minor improvements around these classes. ### Init signature A (sigh) breaking change is tentatively introduced to the constructor. To me, the advantages outweigh the possible discomfort: the new syntax places the DB-connection objects `session` and `keyspace` later in the param list, so that they can be given a default value. This is what enables the pattern of _not_ specifying them, provided one has previously initialized the Cassandra connection through the versatile utility method `cassio.init(...)`. In this way, a much less unwieldy instantiation can be done, such as `CassandraCache()` and `CassandraSemanticCache(embedding=xyz)`, everything else falling back to defaults. A downside is that, compared to the earlier signature, this might turn out to be breaking for those doing positional instantiation. As a way to mitigate this problem, this PR typechecks its first argument trying to detect the legacy usage. (And to make this point less tricky in the future, most arguments are left to be keyword-only). If this is considered too harsh, I'd like guidance on how to further smoothen this transition. Our plan is to make the pattern of optional session/keyspace a standard across all Cassandra classes, so that a repeatable strategy would be ideal. A possibility would be to keep positional arguments for legacy reasons but issue a deprecation warning if any of them is actually used, to later remove them with 0.2 - please advise on this point. ### Other changes - class docstrings: enriched, completely moved to class level, added note on `cassio.init(...)` pattern, added tiny sample usage code. - semantic cache: revised terminology to never mention "distance" (it is in fact a similarity!). Kept the legacy constructor param with a deprecation warning if used. - `llm_caching` notebook: uniform flow with the Cassandra and Astra DB separate cases; better and Cassandra-first description; all imports made explicit and from community where appropriate. - cache integration tests moved to community (incl. the imported tools), env var bugfix for `CASSANDRA_CONTACT_POINTS`. --------- Co-authored-by: Erick Friis <erick@langchain.dev>	3 months ago
