+--------------------
+ * Scan window:
+ - complete redesign based on pthreads to fix terminal bug, as a result of better
+ design the scan window now also can be suspended (details of fix are below),
+ - add message for 'too much data' (E2BIG) error case,
+ - use same formatting (3 digits) for 2/5 GHz,
+ - support for changing sort order via keyboard shortcuts (see manpage, several
+ ascending/descending sort orders are now available directly on the screen),
+ - currently active sort order is now displayed on status line at the bottom,
+ - stabilized by-channel sort to always use the same order for identical channels,
+ - added 'sort by Essid' to selection of sort menus;
+ * Info window:
+ - add percentage for easier reading of link quality,
+ - deprecate use of locale settings for 'discard' information (fixes display);
+ * Configuration screen:
+ - add support for Page Up/Down, Home, and End buttons to ease navigation,
+ - added more information to '-v' version information (ncurses/WE versions);
+ * Bug fixes:
+ - fix bug in ranking top/bottom 3 channels in scan window,
+ - complete redesign of scan process based on pthreads to fix bug that became
+ visible on ncurses >= 5.9.20130504 (slackware 14.1 and debian jessie), caused
+ by child/parent both updating the same screen (bug had been hidden by the
+ internal buffering of ncurses which was then removed), reported by Nick Warne.

is not an access point.
