"One of Fedora's main objectives is not only to contain software distributed under a free and open source license, but also to be on the leading edge of such technologies.[5][6] Fedora developers prefer to make upstream changes instead of applying fixes specifically for Fedora—this ensures that their updates are available to all Linux distributions.[7] A version of Fedora has a relatively short life cycle—the maintenance period is only 13 months: there are 6 months between releases, and version X is supported only until 1 month after version X+2.[8] This promotes leading-edge software because it frees developers from some backward compatibility restraints, but it also makes Fedora a poor choice for product development (e.g., embedded systems), which usually requires long-term vendor-support, unavailable with any version of Fedora."
