Subject: [PATCH 05/12] Native Webhook Integration Sumologic (#17630)

* Fix: Support generic_api_compatible_callbacks.json in callback initialization

- Added check in _add_custom_callback_generic_api_str to load callbacks from generic_api_compatible_callbacks.json
- Added SumoLogic webhook integration to generic_api_compatible_callbacks.json
- Fixes bug where callbacks in JSON file were not being loaded

* Added 3 unit tests for JSON callback loading

Subject: [PATCH 08/12] fix(proxy): async_post_call_streaming_iterator_hook now
 properly iterates async generators (#17626)

The async_post_call_streaming_iterator_hook function was broken:
1. Was a sync function (def) not async generator
2. Returned AsyncGenerator without iterating it
3. Callback generators were chained but never consumed

This fix:
1. Makes the function an async generator (async def + yield)
2. Actually iterates through the chained callbacks with 'async for'
3. Properly yields chunks to the caller

Fixes #9639

+# Onyx Security
+
+## Quick Start
+
+### 1. Create a new Onyx Guard policy
+
+Go to [Onyx's platform](https://app.onyx.security) and create a new AI Guard policy.
+After creating the policy, copy the generated API key.
+
+### 2. Define Guardrails on your LiteLLM config.yaml
+
+Define your guardrails under the `guardrails` section:
+
+```yaml showLineNumbers title="litellm config.yaml"
+model_list:
+  - model_name: gpt-4o-mini
+    litellm_params:
+      model: openai/gpt-4o-mini
+      api_key: os.environ/OPENAI_API_KEY
+
+guardrails:
+  - guardrail_name: "onyx-ai-guard"
+    litellm_params:
+      guardrail: onyx
+      mode: ["pre_call", "post_call", "during_call"] # Run at multiple stages
+      default_on: true
+      api_base: os.environ/ONYX_API_BASE
+      api_key: os.environ/ONYX_API_KEY
+```
+
+#### Supported values for `mode`
+
+- `pre_call` Run **before** LLM call, on **input**
+- `post_call` Run **after** LLM call, on **input & output**
+- `during_call` Run **during** LLM call, on **input**. Same as `pre_call` but runs in parallel with the LLM call. Response not returned until guardrail check completes
+
+### 3. Start LiteLLM Gateway
+
+```shell
+litellm --config config.yaml --detailed_debug
+```
+
+### 4. Test request
+
+<Tabs>
+<TabItem label="Blocked request" value="not-allowed">
+This request should be blocked since it contains prompt injection
+
+```shell showLineNumbers title="Curl Request"
+curl -i http://0.0.0.0:4000/v1/chat/completions \

+
+## Supported Params
+
+```yaml
+guardrails:
+  - guardrail_name: "onyx-ai-guard"
+    litellm_params:
+      guardrail: onyx
+      mode: ["pre_call", "post_call", "during_call"] # Run at multiple stages
+      api_key: os.environ/ONYX_API_KEY
+      api_base: os.environ/ONYX_API_BASE
+```
+
+### Required Parameters
+
+- **`api_key`**: Your Onyx Security API key (set as `os.environ/ONYX_API_KEY` in YAML config)
+
+### Optional Parameters
+
+- **`api_base`**: Onyx API base URL (defaults to `https://ai-guard.onyx.security`)
+
+## Environment Variables
+
+You can set these environment variables instead of hardcoding values in your config:
+
+```shell
+export ONYX_API_KEY="your-api-key-here"
+export ONYX_API_BASE="https://ai-guard.onyx.security"   # Optional
+```

Subject: [PATCH 10/12] fix(anthropic): handle partial JSON chunks in streaming
 responses (#17493)

Fixes #17473 - Anthropic streaming fails with JSONDecodeError when
network fragmentation causes SSE data to arrive in partial chunks.

Changes:
- Add accumulated_json buffer and chunk_type to ModelResponseIterator
- Add _handle_accumulated_json_chunk() to accumulate partial JSON
- Add _parse_sse_data() to handle both complete and partial chunks
- Modify __next__ and __anext__ to use accumulation logic
- Add unit tests for partial chunk handling

Subject: [PATCH 12/12] Document missing environment variables and fix
 incorrect types (#17649)

* fix: correct type annotations for anthropic streaming handlers

- Fix return type of _handle_accumulated_json_chunk from Optional[GenericStreamingChunk] to Optional[ModelResponseStream]
- Fix return type of _parse_sse_data from Optional[GenericStreamingChunk] to Optional[ModelResponseStream]
- Add type annotation for output_items in background_streaming.py

These changes align type annotations with actual return values from chunk_parser() which returns ModelResponseStream.

* docs: add missing ONYX_API_KEY and ONYX_API_BASE to environment variables reference

- Add ONYX_API_BASE documentation entry
- Add ONYX_API_KEY documentation entry
- Fixes test_env_keys.py test failure
