 (Format: Year/Month/Day)
 Changes for 0.9.6:
+*03/11/16:
+  * Add image search paths when loading a style (Simon)
+    - now looks for pixmaps in <stylebase> and <stylebase>/pixmaps
+    - now looks for styles in <stylesdir>/<stylename>/theme.cfg
+      => for this, stylebase is the style directory
+    - pixmap styles should use the new format for portability
+    Theme.hh/cc Image.hh/cc Screen.cc
 *03/11/15:
   * Moved fluxbox-generate_menu to fluxbox-generate_menu.in  (Thanks Han)
     fixed empty submenu problem
