When run command langchain app new my-app, i get this error:
File
"/home/mauricio/.local/lib/python3.8/site-packages/langchain_cli/utils/pyproject.py",

pyproject_toml: Path, local_editable_dependencies: Iterable[tuple[str,
Path]]
TypeError: 'type' object is not subscriptable
This PR fix the error.
The existing default list of separators for the `RecursiveTextSplitter`
assumes spaces are word boundaries. Some languages [don't use spaces
between
words](https://en.wikipedia.org/wiki/Category:Writing_systems_without_word_boundaries)
(Chinese, Japanese, Thai, Burmese).
This PR extends the documentation to explain how to cater for those
languages by adding additional punctuation to the separators and
zero-width spaces which are used by some typesetters and will assist the
splitter to not split in words.
Ideally, **these separators could be a constant in the module** but for
now, defining them in the documentation is a start.

This PR aims to enhance the documentation for TiDB integration, driven
by feedback from our users. It provides detailed introductions to key
features, ensuring developers can fully leverage TiDB for AI application
development.
**Description:**

This PR adds code to make sure that the correct base URL is being
created for the Azure Cognitive Search retriever. At the moment an
incorrect base URL is being generated. I think this is happening because
the original code was based on a depreciated API version. No
dependencies need to be added. I've also added more context to the test
doc strings.
I should also note that ACS is now Azure AI Search. I will open a
separate PR to make these changes as that would be a breaking change and
should potentially be discussed.

- No new tests added, however the current ACS retriever tests are now
passing when I run them.
- Code was linted.

- **Description:** This commit introduces support for the newly
available GPU index types introduced in Milvus 2.4 within the LangChain
project's `milvus.py`. With the release of Milvus 2.4, a range of
GPU-accelerated index types have been added, offering enhanced search
capabilities and performance optimizations for vector search operations.
This update ensures LangChain users can fully utilize the new
performance benefits for vector search operations.

This patch fixes the #18022 issue, converting the SimSIMD internal
zero-copy outputs to NumPy.
I've also noticed, that oftentimes `dtype=np.float32` conversion is used
before passing to SimSIMD. Which numeric types do LangChain users
generally care about? We support `float64`, `float32`, `float16`, and
`int8` for cosine distances and `float16` seems reasonable for
practically any kind of embeddings and any modern piece of hardware, so
we can change that part as well 🤗
- **Description:** Added support for lower-case and mixed-case names
The names for tables and columns previouly had to be UPPER_CASE.
With this enhancement, also lower_case and MixedCase are supported,

- **Description:** Since the implicit `__call__` has been deprecated in
favor of `invoke`, the local_llms article also needed to be updated.
This article was my introduction to Lanchain, and as it was helpful in
getting me setup with running LLMs locally, it is nice to not have any
warnings when running the example code. With this change, the warnings
go away when running the example code.

Previous PR passed _parser attribute which apparently is not meant to be
used by user code and causes non deterministic failures on CI when
testing the transform and a transform methods. Reverting this change
temporarily.

This mitigates a security concern for users still using older versions of libexpat that causes an attacker to compromise the availability of the system if an attacker manages to surface malicious payload to this XMLParser.

Looking at tokens / page of our docs, we see a few outliers:
<img width="761" alt="image"
src="https://github.com/langchain-ai/langchain/assets/122662504/677aa2d6-0a29-45e4-882a-db2bbf46d02b">
It is due to non-rendering images in one case, and output spamming.
Clean these, along with other cases of excessing output spamming in
docs.
All get sucked into chat-langchain for retrieval.
