     1 Release Notes for Version 1.0
     2 --------------------------------
     3 -Jpeg image support added.
     4 -Added new tag parameters to img and legend:
     5 	-removeAfterRender will remove images from storage immediately. Defaults to False. NOTE: This 
     6 	may cause problems if your users expect to copy or save the images from the browser as some
     7 	browsers will put the url in the paste buffer and attempt to reload when pasted somewhere such 
     8 	as MS Word.
     9 	-forceSessionId will add jsessionid parameter to the image url. Defaults to True. This matches
    10 	existing functionality but now allows the option to disable this for certain use cases.
    11 -Supports JFC 1.0.0 Final
    12 	JFC no longer supports the signals chart type. This has been commented out in cewolf for now
    13 	because there is talk on the forum that it may come back.
    14 -At release time, site is not fully updated. This will come in the near future as I move the site fully to Maven2.

    37 -Fixed [ 1158392 ] Configuration object causes NPE when servlet reloads
    38 -Fixed chart-renderer factory problem; that if multiple charts of the same type appeared
    39 	on the same page they shared the same renderer, therefore if a post-processor customized
    40 	that renderer all charts were affected.
