Sep 1, 2025

Month: 2025-09 — License Detection Enhancement: Implemented a top-level COPYING symlink in flipperdevices/u-boot, linking to Licenses/gpl-2.0.txt to provide a single, consistent license reference. This improves machine readability for license detection tools and avoids duplicating license text. Commit: a239b0b0b6dbe6a168969b8cd6e600cf85db278d.
