LibreCMC

LibreCMC is a Linux-libre distribution for computers with minimal resources, such as the Ben NanoNote, ath9k-based Wi-Fi routers, and other hardware with emphasis on free software. Based on OpenWrt, the project's goal is to aim for compliance with the GNU Free System Distribution Guidelines (GNU FSDG) and ensure that the project continues to meet these requirements set forth by the Free Software Foundation (FSF). LibreCMC does not support ac (Wi-Fi 5) or ax (Wi-Fi 6) due to a lack of free chipsets.

As of 2020, releases do not utilize codenames anymore. The acronym "CMC" in the libreCMC name stands for "Concurrent Machine Cluster".

History
On April 23, 2014, libreCMC's first public release is mentioned in a Trisquel Linux forum. On September 4, 2014, the Free Software Foundation (FSF) added libreCMC to its list of endorsed distributions. Shortly afterwards, on September 12, 2014, the FSF awarded their Respects Your Freedom (RYF) Certification to a new router pre-installed with libreCMC.

On May 2, 2015, libreCMC merged with the LibreWRT project. LibreWRT, initially developed as a case study, was listed by the website prism-break.org as one of the alternatives to proprietary firmware, but today the website lists libreCMC.

On March 10, 2016, the FSF awarded their RYF certification to a new router pre-installed with libreCMC.

On March 29, 2017, libreCMC began its first release based upon the LEDE (Linux Embedded Development Environment) 17.01 codebase.

On January 3, 2020, libreCMC began its first release based upon the OpenWrt 19.07 codebase.
