April 2025 accomplishments for the qmk_firmware repository focused on expanding hardware support and improving configurability for end users. Delivered two major keyboard integrations that broaden the product ecosystem, improved build and customization guidance, and set clearer patterns for future keyboard integrations.

March 2025 monthly summary for qmk/qmk_firmware: Delivered a targeted keymap alignment correction for Cerberus HS that fixes the placement of the right shift key and aligns right modifier keys with standard layouts. This improvement enhances usability and consistency across keyboards, reducing user confusion and support friction. The change was committed as e7c5695a0c09d9d673b2185548cae43a38026085 and linked to issue #25043. Overall impact includes higher firmware quality, better developer experience during layout iterations, and stronger adherence to common keyboard layout standards.

December 2024: Delivered new keyboard model support in QMK firmware by adding Cerberus and Reverie integrations. Implementations include configuration files, per-variant keymaps (hotswap and solderable where applicable), backlight control, updated documentation, and JSON definitions for keyboard layouts. All changes are backed by focused commits and improved developer experience. No major bugs fixed this month. Impact: expands hardware compatibility, accelerates user onboarding for new keyboards, and strengthens QMK's maintainability for future models.
