+## v1.10.22
+---
+### Enhanced Anthropic PDF Support
+- Added transformation logic to support OpenAI-spec-compatible `file` content parts in request.
+- Introduced two new Portkey parameters for the `file` content parts: `file_url` and `mime_type`.
+- Applicable for Anthropic, Bedrock-Anthropic and VertexAI-Anthropic models.
+- [Docs](/integrations/llms/anthropic#processing-pdfs-with-claude)
+
+### OTEL Configurations
+- Added two new environment variables:
+    - `OTEL_SERVICE_NAME`: Sets the `service.name` resource attribute value.
+    - `OTEL_RESOURCE_ATTRIBUTES`: Comma-separated `key=value` pairs which will be sent as individual resource attributes.
+
+### New Providers
+- **Ncompass**: Supports chat completions endpoint.
+- **Lepton**: Supports chat completions, completions and transcriptions endpoints.
+- **Snowflake Cortex**: Supports chat completions endpoint.
+
+### Provider Updates
+- **Groq**: Handled an exception that occurred when `stream_options` was included in the request, because the response transformer was not handling `usage` chunk mapping as expected.
+- **Workers AI**: Added support for `/images/generations` route.
+- **Openrouter**: Added support for `usage` request parameter and response mapping.
+- **Deepinfra**: Handled `ping` event returned in stream and mapped `usage` field returned in the response.
+- **VertexAI**: Now returns 400 (instead of 500) for empty model validation errors.
+
+### Fixes And Improvements
+- For providers except OpenAI and Azure-OpenAI, updated the value of `object` field in chat completions response from `chat_completion` to `chat.completion` for OpenAI spec compliance.
+- **Proxy (Passthrough) Requests**: Fixed endpoint construction logic, which was affecting a few provider-route combinations.
+- **Unified Batches**: Fixed issue where embeddings batch output was being returned as empty.
+- **Prometheus**: Fixed issue where `model` label was set as N/A for Bedrock requests.
