security scanners can't distinguish monorepo sources from each other.
this will resolve issues for folks trying to use e.g. langchain-core but
getting security issues from experimental flagged!
The `Without examples 😿` and `With examples 😻` should have different
outputs to illustrate their point.
See v0.2 docs.

- **Description:** This pull request addresses the validation error in
`SettingsConfigDict` due to extra fields in the `.env` file. The issue
is prevalent across multiple Langchain modules. This fix ensures that
extra fields in the `.env` file are ignored, preventing validation
errors.
**Changes include:**
- Applied fixes to modules using `SettingsConfigDict`.
- **Issue:** NA, similar
https://github.com/langchain-ai/langchain/issues/26850
- **Dependencies:** NA
- **Description:** The flag is named `anonymize_snippets`. When set to
true, the Pebblo server will anonymize snippets by redacting all
personally identifiable information (PII) from the snippets going into
VectorDB and the generated reports
- **Issue:** NA
- **Dependencies:** NA
- **docs**: Updated
Description: Resolve CVE-2024-46946 by switching out sympify with
parse_expr with a very specific allowed set of operations.
https://nvd.nist.gov/vuln/detail/cve-2024-46946
Sympify uses eval which makes it vulnerable to code execution.
parse_expr is limited to specific expressions.

**Description:** Moves yield to after callback for `_stream` and
`_astream` function for the deepsparse model in the community package
**Issue:** #16913
- this flag ensures the tracer always runs in the same thread as the run
being traced for both sync and async runs
- pro: less chance for ordering bugs and other oddities
- blocking the event loop is not a concern given all code in the tracer
holds the GIL anyway
- **Description:** This PR fixes the response parsing logic for
`ChatDeepInfra`, more specifially `_convert_delta_to_message_chunk()`,
which is invoked when streaming via `ChatDeepInfra`.
- **Issue:** Streaming from DeepInfra via `ChatDeepInfra` is currently
broken because the response parsing logic doesn't handle that
`tool_calls` can be `None`. (There is no GitHub issue for this problem
yet.)

`_aprepare_input_and_invoke_stream` for bedrock llm in community
package.

without this `model_config` importing this package produces warnings
about "model_name" having conflicts with protected namespace "model_".

Chunking of the input array controlled by `self.chunk_size` is being
ignored when `self.check_embedding_ctx_length` is disabled. Effectively,
the chunk size is assumed to be equal 1 in such a case. This is
suprising.
The PR takes into account `self.chunk_size` passed by the user.

In the previous implementation, `skip_count` was counting all the
documents in the collection. Instead, we want to filter the documents by
`session_id` and calculate `skip_count` by subtracting `history_size`
from the filtered count.
