1.0.6 : (26-Sep-2006) BugFixes in the TextLayoutUtilities, SpreadSheetDate and ResourceBundleSupport classes.
1.0.5 : (29-Jun-2006) BugFixes in the boot code (synchronization added) and WaitingImageObserver (possible deadlock fixed). ObjectUtilities did not handle all cases where a ClassLoader could be null.
1.0.4 : (30-Apr-2006) Date- and NumberCellRenderer did not handle null-values properly.
1.0.3 : (17-Apr-2006) More improvements in the boot process for dependent library hierarchies.
1.0.1 : (10-Feb-2006) This release adds new boot capabilities and fixes some bugs in the XML classes. This version is required for JFreeReport and it is fully backward compatible with the 1.0.x branch.
1.0.0 : (14-Nov-2005) This is the official 1.0.0 release. All future releases in the 1.0.x series will maintain backward compatibility with the 1.0.0 API.
1.0.0-rc1 : (01-Jun-2005) : Update to coincide with JFreeReport 0.8.5-5. JavaDoc update and classloader handling changed.
1.0.0-pre3 : (15-Apr-2005) : Some minor changes in the ResourceBundleSupport to allow the explicit definition of a locale.
1.0.0-pre2 : (04-Mar-2005) : Update to coincide with JFreeReport 0.8.5. Separated the xml-support packages into an own jar file. JFreeChart does not use these classes (except in experimental non-release code). Therefore, JFreeChart needs both libs to build, but only the jcommon.jar library to run.

CHANGELOG.txt file.
