During February 2025, Cedric Chedaleux enhanced the coolsnowwolf/immortalwrt repository by developing an efficiency-focused feature for feed updates. He implemented shallow cloning within update scripts, including submodule handling, to reduce both bandwidth and disk usage during repository synchronization. This approach leveraged Git and shell scripting to optimize the update process, ensuring faster and more reliable feed cycles. By applying shallow clone techniques across modules, Cedric improved cross-module consistency and repository maintenance. Although no bugs were addressed during this period, his work demonstrated a focused application of scripting and version control skills to solve resource efficiency challenges in large-scale codebases.
