1.4 +Release Notes for Version 1.0
1.5 +--------------------------------
1.6 +-Jpeg image support added.
1.7 +-Added new tag parameters to img and legend:
1.8 + -removeAfterRender will remove images from storage immediately. Defaults to False. NOTE: This
1.9 + may cause problems if your users expect to copy or save the images from the browser as some
1.10 + browsers will put the url in the paste buffer and attempt to reload when pasted somewhere such
1.11 + as MS Word.
1.12 + -forceSessionId will add jsessionid parameter to the image url. Defaults to True. This matches
1.13 + existing functionality but now allows the option to disable this for certain use cases.
1.14 +-Supports JFC 1.0.0 Final
1.15 + JFC no longer supports the signals chart type. This has been commented out in cewolf for now
1.16 + because there is talk on the forum that it may come back.
1.17 +-At release time, site is not fully updated. This will come in the near future as I move the site fully to Maven2.
1.18 +

1.28 +-There where significant changes to the JFC Api in this release. See www.jfree.org forums

1.43 + that renderer all charts were affected.
