Eugene Yurtsev	604dfe2d99	community[patch]: Force opt-in for WebResearchRetriever (CVE-2024-3095) (#24451 ) This PR addresses the issue raised by (CVE-2024-3095) https://huntr.com/bounties/e62d4895-2901-405b-9559-38276b6a5273 Unfortunately, we didn't do a good job writing the initial report. It's pointing at both the wrong package and the wrong code. The affected code is the Web Retriever not the AsyncHTMLLoader, and the WebRetriever lives in langchain-community The vulnerable code lives here: `0bd3f4e129/libs/community/langchain_community/retrievers/web_research.py (L233-L233)` This PR adds a forced opt-in for users to make sure they are aware of the risk and can mitigate by configuring a proxy: `0bd3f4e129/libs/community/langchain_community/retrievers/web_research.py (L84-L84)`	2 months ago

Rafael Pereira	6a45bf9554	community[minor]: GraphCypherQAChain to accept additional inputs as provided by the user for cypher generation (#24300 ) Description: This PR introduces a change to the `cypher_generation_chain` to dynamically concatenate inputs. This improvement aims to streamline the input handling process and make the method more flexible. The change involves updating the arguments dictionary with all elements from the `inputs` dictionary, ensuring that all necessary inputs are dynamically appended. This will ensure that any cypher generation template will not require a new `_call` method patch. Issue: This PR fixes issue #24260.	2 months ago
Philippe PRADOS	f5856680fe	community[minor]: add mongodb byte store (#23876 ) The `MongoDBStore` can manage only documents. It's not possible to use MongoDB for an `CacheBackedEmbeddings`. With this new implementation, it's possible to use: ```python CacheBackedEmbeddings.from_bytes_store( underlying_embeddings=embeddings, document_embedding_cache=MongoDBByteStore( connection_string=db_uri, db_name=db_name, collection_name=collection_name, ), ) ``` and use MongoDB to cache the embeddings !	2 months ago

Eun Hye Kim	9aae8ef416	core[patch]: Fix utils.json_schema.dereference_refs (#24335 KeyError: 400 in JSON schema processing) (#24337 ) Description: This PR fixes a KeyError: 400 that occurs in the JSON schema processing within the reduce_openapi_spec function. The _retrieve_ref function in json_schema.py was modified to handle missing components gracefully by continuing to the next component if the current one is not found. This ensures that the OpenAPI specification is fully interpreted and the agent executes without errors.

keval dekivadiya	06f47678ae	community[minor]: Add TextEmbed Embedding Integration (#22946 ) Description: TextEmbed is a high-performance embedding inference server designed to provide a high-throughput, low-latency solution for serving embeddings. It supports various sentence-transformer models and includes the ability to deploy image and text embedding models. TextEmbed offers flexibility and scalability for diverse applications. - PyPI Package: [TextEmbed on PyPI](https://pypi.org/project/textembed/) - Docker Image: [TextEmbed on Docker Hub](https://hub.docker.com/r/kevaldekivadiya/textembed) - GitHub Repository: [TextEmbed on GitHub](https://github.com/kevaldekivadiya2415/textembed) PR Description This PR adds functionality for embedding documents and queries using the `TextEmbedEmbeddings` class. The implementation allows for both synchronous and asynchronous embedding requests to a TextEmbed API endpoint. The class handles batching and permuting of input texts to optimize the embedding process. Example Usage: ```python from langchain_community.embeddings import TextEmbedEmbeddings # Initialise the embeddings class embeddings = TextEmbedEmbeddings(model="your-model-id", api_key="your-api-key", api_url="your_api_url") # Define a list of documents documents = [ "Data science involves extracting insights from data.", "Artificial intelligence is transforming various industries.", "Cloud computing provides scalable computing resources over the internet.", "Big data analytics helps in understanding large datasets.", "India has a diverse cultural heritage." ] # Define a query query = "What is the cultural heritage of India?" # Embed all documents document_embeddings = embeddings.embed_documents(documents) # Embed the query query_embedding = embeddings.embed_query(query) # Print embeddings for each document for i, embedding in enumerate(document_embeddings): print(f"Document {i+1} Embedding:", embedding) # Print the query embedding print("Query Embedding:", query_embedding) --------- Co-authored-by: Eugene Yurtsev <eugene@langchain.dev>	2 months ago

Use "docs: ..." for purely docs changes, "templates: ..." for template changes, "infra: ..." for CI changes. - Example: "community: add foobar LLM" - [ ] PR message: *Delete this entire checklist* and replace with - Description: a description of the change - Issue: the issue # it fixes, if applicable - Dependencies: any dependencies required for this change - Twitter handle: if your PR gets announced, and you'd like a mention, we'll gladly shout you out! - [ ] Add tests and docs: If you're adding a new integration, please include 1. a test for the integration, preferably unit tests that do not rely on network access, 2. an example notebook showing its use. It lives in `docs/docs/integrations` directory. - [ ] 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.

Evan Harris	61ea7bf60b	Add a `ListRerank` document compressor (#13311 ) - Description: This PR adds a new document compressor called `ListRerank`. It's derived from `BaseDocumentCompressor`. It's a near exact implementation of introduced by this paper: [Zero-Shot Listwise Document Reranking with a Large Language Model](https://arxiv.org/pdf/2305.02156.pdf) which it finds to outperform pointwise reranking, which is somewhat implemented in LangChain as [LLMChainFilter](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/retrievers/document_compressors/chain_filter.py). - Issue: None - Dependencies: None - Tag maintainer: @hwchase17 @izzymsft - Twitter handle: @HarrisEMitchell Notes: 1. I didn't add anything to `docs`. I wasn't exactly sure which patterns to follow as [cohere reranker is under Retrievers](https://python.langchain.com/docs/integrations/retrievers/cohere-reranker) with other external document retrieval integrations, but other contextual compression is [here](https://python.langchain.com/docs/modules/data_connection/retrievers/contextual_compression/). Happy to contribute to either with some direction. 2. I followed syntax, docstrings, implementation patterns, etc. as well as I could looking at nearby modules. One thing I didn't do was put the default prompt in a separate `.py` file like [Chain Filter](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/retrievers/document_compressors/chain_filter_prompt.py) and [Chain Extract](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/retrievers/document_compressors/chain_extract_prompt.py).
