Backwards compatibility with older versions of Linux
Backwards compatibility with older versions of Linux v0.5.1 brings to the table backwards compatibility with older versions of Linux. Before this update only versions using glibc 2.29 or newer would work, and not a whole lot of Minecraft hosting providers offer such a recent version.
As of rConsole v0.5.1, glibc 2.23 and new is supported. Most hosting providers will have this version, or newer.
