v2.19.5

Fixed

• OpenAI-compatible embeddings return base64 instead of float — Added encoding_format: "float" to OpenAI-compatible embedding payloads (both sync and async). Some providers (e.g., OpenRouter) return base64-encoded embeddings when encoding_format is not explicitly set, causing "could not convert string to float" errors at parse time.

Changed

• Azure documentation: recommend latest API version — Updated all Azure provider documentation examples to recommend 2024-10-21 (latest stable) instead of the outdated 2024-02-01.
