 * Find backward/forward function is now incremental.
 * Support for 256 colors and customization of background colors has been added.
 * Multiple configuration files via command line arguments are now accepted. In addition, by default ncmpcpp attempts to read both $HOME/.ncmpcpp/config and $XDG_CONFIG_HOME/ncmpcpp/config (in this order).
+* Support for PDCurses has been removed due to the library being unmaintained and buggy.
