It's worth noting, that of the new features, most if not all of them appear to be concentrated in the four core apps: Writer, Calc, Impress and Draw.
In the future, LibreOffice plans to punch up the existing Ubuntu and Android apps (there are no plans to support iOS, at present) and to eventually launch a cloud version. Users will have the option to try out "LibreOffice Fresh," a generally unsupported "ring" of new builds.
It's probably reasonable to think that Microsoft's own free Office offerings will continue to improve over time, and that their user base will expand as more people become aware of them. On the other hand, there's still room for free, "good enough" alternatives, and LibreOffice seems like it has carved out that niche for itself.
