Summary
Qwen Code's v0.15.6 nightly added a FileReadCache that short-circuits unchanged file reads and shipped a proxy-handling fix for network requests. The release is a concrete example of coding-agent competition moving into runtime efficiency and enterprise-network fit, not just model support.
What changed
Qwen Code added a file-read cache for unchanged reads and fixed proxy handling in network requests.
Why it matters
Repeated file reads waste time and tokens in large codebases, while broken proxy support keeps corporate users out entirely. Qwen is tightening both ends of the workflow: local I/O efficiency and restricted-network usability.
Evidence excerpt
The May 3 CLI digest tied v0.15.6-nightly.20260502.5d1052a35 to FileReadCache and proxy-aware request handling as the lead improvements in the nightly cut.
