-* Adding option &status to get an overview of the installed ond configured utilities.
+* Bundle imgs.php did not have the correct mode.
+* Adding option &status to get an overview of the installed ond configured utilities, #116.
 * Bug, all files saved as png-files, when not saving as specific file. 
 * Removed saving filename extension for alias images.
 * Added option to decide if resample or resize when copying images internally. `&no-resample` makes resize, instead of resample as is default.
