This release replaces the Jacl interpreter with JTcl, an updated verson of Tcl for Java. JTcl implements nearly all Tcl 8.4 features. Community-supported versions of Echo2 and related libraries are included, which fixes compatibility issues with Internet Explorer 9. Also fixed in this release is the updateOptimistic method in the MrPersister package. Window object (".") now has a getClientProperties method. The H2 database has been upgraded to a recent version (see the CHANGES file for upgrade information).

The ExpandableSection widget now has methods to set title foreground and background colors. The WarMachine sample program was enhanced to allow additional JAR library files. The Window method exitApp can now use a logout servlet to exit an application. Bugs fixed include the removing extraneous characters in the hyde package. The ComboBox widget was fixed to avoid backslash quoting of whitespace characters. The library procedure aejaks_entryBox has been changed so that the callback now passes two arguments; this change is incompatible with previous versions and will require a code change.

Some real or potential memory leaks were fixed. Other fixes and enhancements were made to runtime code, affecting the Pack command and sample programs. An 'updateOptimistic' method was added to the GenericDao object in the MrPersister database package. This allows the use of 'optimistic locking' when updating a row in order to avoid hidden updates while maintaining high concurrency. The H2 database engine was updated to the current version.

A bug that prevented the MrPersister database package from working in Java 1.6 was fixed. PersistenceManager and JdbcDao objects were also fixed.

This release has a MrPersister database access library. The H2 Database engine is included for quick-start database application development. Also included are the Apache Log4J logging system, a RichTextArea widget, standard library dialogs for messages, input, color selection, date selection, and file uploads, and a Hyde package for easy Tcl-to-Java integration. New sample applications: TclTutor, Aejaks Rolodex, and WarMachine.
