Now ClassPool#toClass(CtClass, ClassLoader) should not be overridden. All subclasses of ClassPool must override toClass(CtClass, ClassLoader, ProtectionDomain). * CtClass#getAvailableAnnotations() etc. have been implemented. * A bug related to a way of dealing with a bridge method was fixed ([HIBERNATE-37](http://jira.jboss.com/jira/browse/HIBERNATE-37)). * javassist.scopedpool package was added. #### version 3.2 on June 21, 2006 * The behavior of CtBehavior#getParameterAnnotations() has been changed. It is now compatible to Java Reflection API ([JASSIST-19](http://jira.jboss.com/jira/browse/JASSIST-19)). #### version 3.2.0.CR2 on May 9, 2006 * A bug of replace(String,ExprEditor) in javassist.expr.Expr has been fixed. * Updated ProxyFactory getClassLoader to choose the javassit class loader when the proxy superclass has a null class loader (a jdk/endorsed class) ([JASSIST-18](http://jira.jboss.com/jira/browse/JASSIST-18)). * Updated the throws clause of the javassist.util.proxy.MethodHandler to be Throwable rather than Exception ([JASSIST-16](http://jira.jboss.com/jira/browse/JASSIST-16)). #### version 3.2.0.CR1 on March 18, 2006 * Annotations enhancements to javassist.bytecode.MethodInfo. * Allow a ClassPool to override the "guess" at the classloader to use. #### version 3.1 on February 23, 2006 * getFields(), getMethods(), and getConstructors() in CtClass were changed to return non-private memebers instead of only public members. * getEnclosingClass() in javassist.CtClass was renamed to getEnclosingMethod(). * getModifiers() was extended to return Modifier.STATIC if the class is a static inner class. * The return type of CtClass.stopPruning() was changed from void to boolean. * toMethod() in javassist.CtConstructor has been implemented. * It includes new javassist.util.proxy package similar to Enhancer of CGLIB. * The subpackages of Javassist were restructured. * javassist.tool package was renamed to javassist.tools. * HotSwapper was moved to javassist.util. * Several subpackages were moved to javassist.tools. * javassist.preproc package was elminated and the source was moved to the sample directory. #### version 3.1 RC2 on September 7, 2005 * RC2 is released mainly for an administrative reason. * A few bugs have been fixed. #### version 3.1 RC1 on August 29, 2005 * Better annotation supports.

Simple changes for integration with JBoss AOP * Made ClassPool.get0 protected so that subclasses of ClassPool can call it. * Moved all access to the class cache (the field ClassPool.classes) to a method called getCached(String classname). This is so subclasses of ClassPool can override this behavior. #### version 2.5 in May, 2003. From this version, Javassist is part of the JBoss project. * The license was changed from MPL to MPL/LGPL dual. * ClassPool.removeClassPath() and ClassPath.close() have been added. * ClassPool.makeClass(InputStream) has been added. * CtClass.makeClassInitializer() has been added. * javassist.expr.Expr has been changed to a public class. * javassist.expr.Handler has been added. * javassist.expr.MethodCall.isSuper() has been added. * CtMethod.isEmpty() and CtConstructor.isEmpty() have been added. * LoaderClassPath has been implemented. #### version 2.4 in February, 2003. * The compiler included in Javassist did not correctly work with interface methods.

Thanks. * CtMethod.setBody() and CtConstructor.setBody() have been added. * javassist.reflect.ClassMetaobject.useContextClassLoader has been added. If true, the reflection package does not use Class.forName() but uses a context class loader specified by the user. * $sig and $type are now available. * Bugs in Bytecode.write() and read() have been fixed. #### version 2.2 in October, 2002. * The tutorial has been revised. * A new package `javassist.expr` has been added. This is replacement of classic `CodeConverter`. * javassist.ConstParameter was changed into javassist.CtMethod.ConstParameter. * javassist.FieldInitializer was renamed into javassist.CtField.Initializer. * A bug in javassist.bytecode.Bytecode.addInvokeinterface() has been fixed. * In javassist.bytecode.Bytecode, addGetfield(), addGetstatic(), addInvokespecial(), addInvokestatic(), addInvokevirtual(), and addInvokeinterface() have been modified to update the current statck depth. #### version 2.1 in July, 2002. * javassist.CtMember and javassist.CtBehavior have been added. * javassist.CtClass.toBytecode() has been added. * javassist.CtClass.toClass() and javassist.ClassPool.writeAsClass() has been added. * javassist.ByteArrayClassPath has been added. * javassist.bytecode.Mnemonic has been added. * Several bugs have been fixed. #### version 2.0 (major update) in November, 2001. * The javassist.bytecode package has been provided. It is a lower-level API for directly modifying a class file although the users must have detailed knowledge of the Java bytecode. * The mechanism for creating CtClass objects have been changed. * javassist.tool.Dump moves to the javassist package. version 1.0 in July, 2001. * javassist.reflect.Metaobject and ClassMetaobject was changed. Now they throw the same exception that they receive from a base-level object. #### version 0.8 * javassist.tool.Dump was added. It is a class file viewer. * javassist.FiledInitializer.byNewArray() was added. It is for initializing a field with an array object. * javassist.CodeConverter.redirectMethodCall() was added. * javassist.Run was added. #### version 0.7 * javassit.Loader was largely modified. javassist.UserLoader was deleted. Instead, Codebase was renamed to ClassPath and UserClassPath was added. Now programmers who want to customize Loader must write a class implementing UserClassPath instead of UserLoader. This change is for sharing class search paths between Loader and CtClass.CtClass(String). * CtClass.addField(), addMethod(), addConstructor(), addWrapper() were also largely modified so that it receives CtNewMethod, CtNewConstructor, or CtNewField. The static methods for creating these objects were added to the API. * Constructors are now represented by CtConstructor objects. CtConstructor is a subclass of CtMethod. * CtClass.getUserAttribute() was removed. Use CtClass.getAttribute(). * javassist.rmi.RmiLoader was added. * javassist.reflect.Metalevel._setMetaobject() was added. Now metaobjects can be replaced at runtime. #### version 0.6 * Javassist was modified to correctly deal with array types appearing in signatures. * A bug crashed resulting bytecode if a class includes a private static filed.

Many classes and methods were changed. Most of methods taking java.lang.Class have been changed to take javassist.CtClass. #### version 0.3 * Major update. Many classes and methods were changed. #### version 0.2 * Jar/zip files are supported. #### version 0.1 on April 16, 1999. * The first release.
