 ### For Details See [Speed Camera GitHub Wiki](https://github.com/pageauc/rpi-speed-camera/wiki)
 
-* NEW: Added search-speed.py that uses opencv template matching to find similar images.  To use,
-        copy one or more search image(s) to the default search folder media/search and run search-speed.py.  
-        if the config.py variable copy_results_on=True then image match files including orignal search file 
-        are copied to a subfolder with the same name as the search image filename but without the file extension. 
-        If you set config.py gui_window_on=True a Searching and Target window will be displayed on the
-        RPI desktop.  When a match is found it will be displayed for 4 seconds.
-        Results can also be reviewed from a web browser by running ./webserver.py and accessing link for search/subfolder
-        (Note: search-speed.py is still under development)
+* 6.00  Added Optional SubDir creation by number of files or by SubDir Age
+        Also Added Disk Space Management that deletes oldest file in specified Dir Tree
+        to maintain a specified amount of Free disk space (default 500 MB)
+        Also added try, except, pass for loading of pi-camera libraries
+        This should allow speed-cam.py to work on Non RPI platforms with Web Cam eg Ubuntu or windows       
+
+* 5.00 Added search-speed.py that uses opencv template matching to find similar images.  To use,
+       use menubox.sh menuing or command line to copy one or more search image(s) to the
+       default media/search folder and run search-speed.py.  
+       if the config.py variable copy_results_on=True then image match files including orignal search file 
+       are copied to a subfolder with the same name as the search image filename but without the file extension.
