Release Notes

Support for Llama3 models on AWS Bedrock.
Support for MistralAI and new Claude 3 models on AWS Bedrock.
Upgrade transformers to version 4.39.3 so that Haystack can support the new Cohere Command R models.

Fixes SearchEngineDocumentStore.get_metadata_values_by_key method to make use of self.index if no index is provided.
When using a Pipeline with a JoinNode (e.g. JoinDocuments) all information from the previous nodes was lost other than a few select fields (e.g. documents). This was due to the JoinNode not properly passing on the information from the previous nodes. This has been fixed and now all information from the previous nodes is passed on to the next node in the pipeline.
For example, this is a pipeline that rewrites the query during pipeline execution combined with a hybrid retrieval setup that requires a JoinDocuments node. Specifically the first prompt node rewrites the query to fix all spelling errors, and this new query is used for retrieval. And now the JoinDocuments node will now pass on the rewritten query so it can be used by the QAPromptNode node whereas before it would pass on the original query.
