Chakra , one of the best pro-KDE distributions , is abandoning support for i686 (32-bit) processors to focus all its efforts on x86_64 (64-bit) processors due to the latter's boom in the market.
Due to the increasing prevalence of 32-bit processors, fewer and fewer (test) users of this distribution are using 32-bit systems, making support more difficult. Therefore, the next logical step in Chakra 's evolution , according to its developers, is to definitively abandon this platform, as other distributions already provide support for it.
For the next 2-3 months, Chakra users will receive all bug fixes and security updates. After that, the i686 repositories and their mirrors will be maintained indefinitely, but without support.
