Erick Friis	17a06cb7a6	infra: check templates based on integration (#24857 ) instead of hardcoding a linter for each, iterate through the lines of the template notebook and find lines that start with `##` (includes lower headings), and enforce that those headings are found in new docs that are contributed	2 months ago

Eugene Yurtsev	210623b409	core[minor]: Add support for pydantic 2 to utility to get fields (#24899 ) Add compatibility for pydantic 2 for a utility function. This will help push some small changes to master, so they don't have to be kept track of on a separate branch.	2 months ago

Eugene Yurtsev	69c656aa5f	langchain[minor]: Upgrade ambiguous root_validator to @pre_init (#24895 ) The @pre_init validator is a temporary solution for base models. It has similar (but not identical) semantics to @root_validator(), but it works strictly as a pre-init validator. It'll work as expected as long as the pydantic model type hints were correct.	2 months ago

Eugene Yurtsev	d24b82357f	community[patch]: Add missing annotations (#24890 ) This PR adds annotations in comunity package. Annotations are only strictly needed in subclasses of BaseModel for pydantic 2 compatibility. This PR adds some unnecessary annotations, but they're not bad to have regardless for documentation pages.	2 months ago

David Robertson	bfb7f8d40a	Brave Search: Enhance search result details with extra snippets (#19209 ) Description: This update significantly improves the Brave Search Tool's utility within the LangChain library by enriching the search results it returns. The tool previously returned title, link, and snippet, with the snippet being a truncated 140-character description from the search engine. To make the search results more informative, this update enables extra_snippets by default and introduces additional result fields: title, link, description (enhancing and renaming the former snippet field), age, and snippets. The snippets field provides a list of strings summarizing the webpage, utilizing Brave's capability for more detailed search insights. This enhancement aims to make the search tool far more informative and beneficial for users. Issue: N/A Dependencies: No additional dependencies introduced. Twitter handle: @davidalexr987 Code Changes Summary: - Changed the default setting to include extra_snippets in search results. - Renamed the snippet field to description to accurately reflect its content and included an age field for search results. - Introduced a snippets field that lists webpage summaries, providing users with comprehensive search result insights. Backward Compatibility Note: The renaming of snippet to description improves the accuracy of the returned data field but may impact existing users who have developed integration's or analyses based on the snippet field. I believe this change is essential for clarity and utility, and it aligns better with the data provided by Brave Search. Additional Notes: This proposal focuses exclusively on the Brave Search package, without affecting other LangChain packages or introducing new dependencies.	2 months ago
