Boris Feld	404abf139a	community: Add CometLLM tracing context var (#15765 ) I also added LANGCHAIN_COMET_TRACING to enable the CometLLM tracing integration similar to other tracing integrations. This is easier for end-users to enable it rather than importing the callback and pass it manually. (This is the same content as https://github.com/langchain-ai/langchain/pull/14650 but rebased and squashed as something seems to confuse Github Action).	6 months ago
Nicolò Boschi	a500527030	infra: google-vertexai relax types-requests deps range (#16264 ) - Description: At the moment it's not possible to include in the same project langchain-google-vertexai and boto3 (e.g. use bedrock and vertex in the same application) because of the dependency resolutions conflict. boto3 is still using urllib3 1.x, meanwhile langchain-google-vertexai -> types-requests depends on urllib3 2.x. [the last version of types-requests that allows urllib3 1.x is 2.31.0.6](https://pypi.org/project/types-requests/#description). In this PR I allow the vertexai package to get that version also. - Twitter handle: nicoloboschi	6 months ago

Alireza Kashani	d1b4ead87c	community[patch]: Update grobid.py (#16298 ) there is a case where "coords" does not exist in the "sentence" therefore, the "split(";")" will lead to error. we can fix that by adding "if sentence.get("coords") is not None:" the resulting empty "sbboxes" from this scenario will raise error at "sbboxes[0]["page"]" because sbboxes are empty. the PDF from https://pubmed.ncbi.nlm.nih.gov/23970373/ can replicate those errors.	6 months ago

Max Jakob	de209af533	community[patch]: ElasticsearchStore: add relevance function selector (#16378 ) Implement similarity function selector for ElasticsearchStore. The scores coming back from Elasticsearch are already similarities (not distances) and they are already normalized (see [docs](https://www.elastic.co/guide/en/elasticsearch/reference/current/dense-vector.html#dense-vector-params)). Hence we leave the scores untouched and just forward them. This fixes #11539. However, in hybrid mode (when keyword search and vector search are involved) Elasticsearch currently returns no scores. This PR adds an error message around this fact. We need to think a bit more to come up with a solution for this case. This PR also corrects a small error in the Elasticsearch integration test. --------- Co-authored-by: Erick Friis <erick@langchain.dev>	6 months ago
