1. Microsoft Reverses VS Code Default That Stamped Copilot as Commit Co-Author

Microsoft. An April 16 merge flipped the git.addAICoAuthor setting in VS Code to all, causing the editor’s Git extension to append Co-Authored-by: Copilot trailers to commits — including for developers who had AI features disabled. After backlash on GitHub and Hacker News (one issue thread topped the repo by reply count), the maintainer behind the change owned the regression and announced a revert: version 1.119 will restore the off-by-default behavior. Users on 1.117 and 1.118 can opt out manually by setting git.addAICoAuthor to off in user or workspace settings. The episode reignited a longer-running debate about whether Co-Authored-by — historically a credit signal for human pair-programming — should be reused for AI provenance. Source
