Pull request 3880 addresses silent data loss where the prose compressor deleted whole records from single-line JSON tool output and left valid JSON behind, so neither parsers nor models could tell. In one deployment that meant an agent confidently said a data collection did not exist when…
Second, cache stability and context trimming. Pull request 3826 fixes the OpenClaw plugin returning every message through a lossy conversion, which dropped thinking blocks, flattened content, and broke provider prompt caching from the first message. Now untouched messages pass through exactly as received. Pull…
