Third Replicant 6.0 release is out!
Replicant is a free software mobile operating system putting the emphasis on freedom and privacy/security.
It is available for several smartphones and tablet computers. It is written in the same programming languages as Android (as it is forked from it, though indirectly), while the modifications are mostly in the C language, as the changes are mostly to the lower-level parts of the OS, such as the Linux kernel and drivers that use it.
Replicant is sponsored and supported by the Free Software Foundation.
