2017.03.31 - GNU nano 2.8.0 "Axat" makes it easier to move around in
                softwrapped lines: the Up and Down keys now step from
                visual row to visual row instead of jumping between
                logical lines, and the Home and End keys now move to
                the start and end of a row, and only when already
                there, then to the start and end of the logical line.
                Furthermore, the screen can now scroll per row instead
                of always per logical line.  On an entirely different
                front: nano now makes use of gnulib, to make it build
                on more platforms.  In short: there were many internal
                changes, not many user-visible ones (apart form the
                new softwrap navigation).  The conversion to gnulib
                was done by Mike Frysinger, the softwrap overhaul by
                David Ramsey.

GNU nano is a simple and easy-to-use editor for the terminal.

The tarball and its signature are here:

Specific bugs that were fixed mostly concern softwrap:  (making PageUp+PageDown immobile)  (scrolling on extremely long lines)  (moving right on very long lines)  (cursor placement after spell check)  (character counts with Unicode Input)  (spotlighting across row boundaries)
