* test(text-splitters): add edge case tests for CharacterTextSplitter (langchain-ai#34628) * chore(groq): document vision support (langchain-ai#34620) * feat(core): support custom message separator in get_buffer_string() (langchain-ai#34569) * chore(langchain): fix types in test_wrap_model_call (langchain-ai#34573) * fix: handle empty assistant content in Responses API (langchain-ai#34272) (langchain-ai#34296) * fix(openai): raise proper exception `OpenAIRefusalError` on structured output refusal (langchain-ai#34619) * release(openai): 1.1.7 (langchain-ai#34640) * fix(core): fix strict schema generation for functions with optional args (langchain-ai#34599) * test(core): add edge case for empty examples in LengthBasedExampleSelector (langchain-ai#34641) * fix(langchain): handle parallel usage of the todo tool in planning middleware (langchain-ai#34637) The agent should only make a single call to update the todo list at a time. A parallel call doesn't make sense, but also cannot work as there's no obvious reducer to use. On parallel calls of the todo tool, we return ToolMessage containing to guide the LLM to not call the tool in parallel. --------- Co-authored-by: Eugene Yurtsev <eyurtsev@gmail.com> * release(langchain): release 1.2.2 (langchain-ai#34643) Release langchain 1.2.2 * fix(langchain): add test to verify version (langchain-ai#34644) verify version in langchain to avoid accidental drift --------- Co-authored-by: Manas karthik <manaskarthik200@gmail.com> Co-authored-by: Aarav Dugar <79491557+AaravDugar123@users.noreply.github.com> Co-authored-by: Chris Papademetrious <chrispy@synopsys.com> Co-authored-by: Christophe Bornet <cbornet@hotmail.com> Co-authored-by: Sujal M H <63709163+sujalmh@users.noreply.github.com> Co-authored-by: OysterMax <sma@esri.com> Co-authored-by: ccurme <chester.curme@gmail.com> Co-authored-by: Mohammad Mohtashim <45242107+keenborder786@users.noreply.github.com> Co-authored-by: Harrison Chase <hw.chase.17@gmail.com> Co-authored-by: Eugene Yurtsev <eyurtsev@gmail.com>
