Release Notes - Version 2.3.2

Overview

Version 2.3.2 is a maintenance release that addresses critical bugs in WebClient Buffer Limit Exception for Large Files.

Problem: DataBufferLimitException thrown when response body exceeds 256KB (default WebClient buffer limit).
Impact: Affected APIs returning large files (e.g., text-to-audio returning 472KB audio files).
Solution: Implemented streaming response handling to avoid buffer limits:
- Changed from retrieve().toEntity(byte[].class) to exchangeToMono() with streaming
- Used bodyToFlux(DataBuffer.class) to read data in chunks
- Immediate DataBuffer release to prevent memory buildup
- Merged chunks using reduce operation
Benefits:
- Handles responses of any size without configuration changes
- Consistent with Spring Boot 3 RestClient behavior
- Improved exception handling and logging (debug → error level)
Affected components:
- WebClientExecutor.executeForEntity() methods (both Class and TypeReference variants)
- WebClientExecutorTest - Updated test mocks to use exchangeToMono()
