We have released version 2.2 of MindFusion.Scheduling for Java Swing. The new version includes:

DateTime changes

• The DateTime class now uses java.time.LocalDateTime for storage and calculations. New constructor and toJavaDateTime method provide access to the stored LocalDateTime for easier interoperability with Java APIs and components.
• LocalDateTime storage allows for much large date range (from -999999999-01-01 to +999999999-12-31).
• Fixed toString results for years older than 1593.
• The Duration class now uses a java.time.Duration for storage and calculations. New constructor and toJavaDuration method provide access to the stored java.time.Duration for easier interoperability with Java APIs and components.

Dark themes
Two dark themes added, accessible via the Dark and Black elements of ThemeType enumeration, and static getDark and getBlack methods of Theme class.
Miscellaneous

• saveToString and loadFromString methods now support ContentType.Json.
• Fixed IllegalAccessError exception when showing standard forms in recent versions of the JDK. Date combo boxes in standard forms no longer use platform-specific ComboBoxUI implementations that cause the exception, but only BasicComboBoxUI.

Distribution for the latest version can be downloaded here, or from the clients area on our site.
