    Instead of pruning, this version of Javassist compresses
    the data structure of a class file after toBytecode() is called.
    The compressed class file is automatically decompressed when needed.
    This saves memory space better than pruning.

* [JIRA JASSIST-33](http://jira.jboss.com/jira/browse/JASSIST-33) has been fixed.

* A synchronization bug and a performance bug in `javassist.util.proxy`
        have been fixed
        ([JASSIST-28](http://jira.jboss.com/jira/browse/JASSIST-28)).
        Now generated proxy classes are cached.  To turn the caching off,
        set `ProxyFactory.useCache` to `false`.

#### version 3.3 on August 17, 2006

* CtClass#toClass() and ClassPool#toClass() were modified to accept a
        `ProtectionDomain`
        ([JASSIST-23](http://jira.jboss.com/jira/browse/JASSIST-23)).
        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.

        ([HIBERNATE-37](http://jira.jboss.com/jira/browse/HIBERNATE-37)).

#### 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.

#### 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.

          infinite while-loop.

#### version 2.5.1 in May, 2003.
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.

* javassist.expr.Instanceof and Cast have been added.

* javassist.expr.{MethodCall,NewExpr,FieldAccess,Instanceof,Cast}.where()
            have been added.  They return the caller-side method surrounding the
    	expression.

* javassist.expr.{MethodCall,NewExpr,FieldAccess,Instanceof,Cast}.mayThrow()
            have been added.

* $class has been introduced.

* The parameters to replaceFieldRead(), replaceFieldWrite(),
          and redirectFieldAccess() in javassist.CodeConverter are changed.

* The compiler could not correctly handle a try-catch statement.
          This bug has been fixed.

* CtMethod.setBody() and CtConstructor.setBody() have been added.

* javassist.reflect.ClassMetaobject.useContextClassLoader has been added.

* Bugs in Bytecode.write() and read() have been fixed.

#### version 2.2 in October, 2002.

* The tutorial has been revised.

            This is replacement of classic `CodeConverter`.

* javassist.ConstParameter was changed into
    	javassist.CtMethod.ConstParameter.

    	javassist.CtField.Initializer.

* A bug in javassist.bytecode.Bytecode.addInvokeinterface() has been
    	fixed.

    	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.  It has been fixed.

* javassist.CtNewInterface was added.

* javassist.Loader.recordClass() was renamed into makeClass().

* javassist.UserLoader.loadClass() was changed to take the second
parameter.

#### version 0.5

* a bug-fix version.

#### version 0.4

* Major update again.  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.
