ffaac42bf9 ci(infra): add pytest-xdist to partner test groups (#36988) 2026-04-24 13:23:03 +00:00

7e81d09f2a chore(deps): bump pytest to 9.0.3 (#36801) 
CVE-2025-71176 (medium severity)

All are dev-only (test dependency group) — no impact on published
packages.

### Why syrupy was also bumped

syrupy 4.x (`<5.0.0`) constrains pytest to `<9.0.0`, blocking the CVE
fix. Widening to `<6.0.0` allows syrupy 5.x which supports pytest 9.x.

0aa482d0cd feat(ollama): logprobs support in Ollama (#34218) 
Closes #34207 

---

Expose log probabilities from the Ollama Python SDK through
`ChatOllama`. The ollama client already returns a `logprobs` field on
chat responses for supported models, but `ChatOllama` had no way to
request or surface it.

## Changes
- Add `logprobs` and `top_logprobs` fields to `ChatOllama`, forwarded to
the client via `_build_chat_params`. Setting `top_logprobs` without
`logprobs=True` auto-enables it with a warning; setting it with
`logprobs=False` raises a `ValueError`
- Surface per-token logprobs on intermediate streaming chunks (both sync
`_create_chat_stream` and async `_create_async_chat_stream`) via
`response_metadata["logprobs"]`, accumulated into the final response on
`invoke()`
- Bump minimum `ollama` SDK from `>=0.6.0` to `>=0.6.1` — the version
that added logprobs support

0f4f3f74c8 chore: pygments>=2.20.0 across all packages (CVE-2026-4539) (#36385) 
## Summary

Bumps `pygments` to `>=2.20.0` across all 21 affected packages to
address [CVE-2026-4539](https://github.com/advisories/GHSA-XXXX) — ReDoS
via inefficient GUID regex in Pygments.

- **Severity:** Low
- **Fixed in:** 2.20.0 (was 2.19.2)
- **Change:** Added `pygments>=2.20.0` to `constraint-dependencies` in
`[tool.uv]` for each package, then ran `uv lock --upgrade-package
pygments` to regenerate lock files.

Closes Dependabot alerts #3435–#3455.

## Release Note
Patch deps

### Test Plan
 - [x] CI Green 🙏

1778b082ec chore(partners): bump langchain-core min to 1.2.21 (#36183) 
Bump the minimum `langchain-core` dependency to `>=1.2.21` across all 14
partner packages in the monorepo. Aligns partner lower bounds with the
latest core release so consumers pick up recent fixes (notably the
`ModelProfile` schema drift fix from core 1.2.21).

0d6f915442 fix: LLM mimicking Unicode responses due to forced Unicode conversion of non-ASCII characters. (#32222) 
fix: Fix LLM mimicking Unicode responses due to forced Unicode
conversion of non-ASCII characters.

- **Description:** This PR fixes an issue where the LLM would mimic
Unicode responses due to forced Unicode conversion of non-ASCII
characters in tool calls. The fix involves disabling the `ensure_ascii`
flag in `json.dumps()` when converting tool calls to OpenAI format.
- **Issue:** Fixes ↓↓↓
input：
```json
{'role': 'assistant', 'tool_calls': [{'type': 'function', 'id': 'call_nv9trcehdpihr21zj9po19vq', 'function': {'name': 'create_customer', 'arguments': '{"customer_name": "你好啊集团"}'}}]}
```
output:
```json
{'role': 'assistant', 'tool_calls': [{'type': 'function', 'id': 'call_nv9trcehdpihr21zj9po19vq', 'function': {'name': 'create_customer', 'arguments': '{"customer_name": "\\u4f60\\u597d\\u554a\\u96c6\\u56e2"}'}}]}
```
then:
llm will mimic outputting unicode. Unicode's vast number of symbols can
lengthen LLM responses, leading to slower performance.

7e926520d5 packaging: remove Python upper bound for langchain and co libs (#31025) 
Follow up to https://github.com/langchain-ai/langsmith-sdk/pull/1696,
I've bumped the `langsmith` version where applicable in `uv.lock`.

Type checking problems here because deps have been updated in
`pyproject.toml` and `uv lock` hasn't been run - we should enforce that
in the future - goes with the other dependabot todos :).

dbf9986d44 langchain-ollama (partners) / langchain-core: allow passing ChatMessages to Ollama (including arbitrary roles) (#30411) 
Replacement for PR #30191 (@ccurme)

**Description**: currently, ChatOllama [will raise a value error if a
ChatMessage is passed to
it](https://github.com/langchain-ai/langchain/blob/master/libs/partners/ollama/langchain_ollama/chat_models.py#L514),
as described
https://github.com/langchain-ai/langchain/pull/30147#issuecomment-2708932481.

Furthermore, ollama-python is removing the limitations on valid roles
that can be passed through chat messages to a model in ollama -
https://github.com/ollama/ollama-python/pull/462#event-16917810634.

This PR removes the role limitations imposed by langchain and enables
passing langchain ChatMessages with arbitrary 'role' values through the
langchain ChatOllama class to the underlying ollama-python Client.

As this PR relies on [merged but unreleased functionality in
ollama-python](
https://github.com/ollama/ollama-python/pull/462#event-16917810634), I
have temporarily pointed the ollama package source to the main branch of
the ollama-python github repo.

Format, lint, and tests of new functionality passing. Need to resolve
issue with recently added ChatOllama tests. (Now resolved)

**Issue**: resolves #30122 (related to ollama issue
https://github.com/ollama/ollama/issues/8955)

**Dependencies**: no new dependencies

[x] PR title
[x] PR message
[x] Lint and test: format, lint, and test all running successfully and
passing
