v1.0.0-rc.23

Highlights: This release expands provider and channel compatibility with New API channels, DeepSeek Responses API support, zstd request decompression, and automatic group routing. It also improves operational accuracy with stream visibility in logs, more reliable tiered-retry billing, and upstream Bedrock cancellation when clients disconnect.

New Features

• Added New API channel support with Gemini-to-OpenAI streaming conversion, Advanced Custom Responses Compact handling, and multipart image edit support (#6559).
• Added DeepSeek Responses API support (#6562).
• Added automatic group selection for request routing (#6590).
• Added per-channel HTTP transport controls so administrators can tune connection behavior per channel.
• Added support for zstd-compressed requests (#6545).
• Log owners can now see whether a request was streamed (#6558).

Bug Fixes

• Qwen thinking_budget is now preserved when requests are relayed (#5836).
• Tiered retry billing now settles usage against the final selected group, including group-switch retries (#6570).
• Bedrock requests are now cancelled when clients disconnect, reducing wasted upstream work (#6589).

Improvements

• Public header navigation links now use a consistent font size (#6557).
