Do not generate handlers for return values if an instrumented method or an advice method only throws exceptions but never returns regularly.

15. July 2016: version 1.4.11

Added tracer for the state of the operand stack for the Advice component to clear the stack upon a return.

Added map-based BinaryLocator.

19. April 2016: version 1.3.14

Only add frames in Advice components if class file version is above 1.5.

Added support for non-inlined Advice method.
Mask modifiers of ASM to not longer leak internal flags beyond the second byte.
Added support for suppressing an exception of the instrumented method from within exit advice.

Avoid reusing labels during the computations of exception tables of the Advice component.

12. April 2016: version 1.3.11

Byte Buddy Advice now appends handlers to an existing exception handler instead of prepending them. Before, existing exception handlers were shadowed when applying suppression or exit advice on an exception.

Replaced generalized token representation to define tokens, type tokens and signature tokens.
General API improvements and minor bug fixes.

4. January 2016: version 0.7.8

Fixed class validator which did not allow <clinit> blocks in interface types.
Added restriction to retransformation to not attempt a retransformation at all if no class should be retransformed.
Added a factory for creating an Implementation.Context that is configurable. This way, it is possible to avoid a rebase of a type initializer which is not always possible.

13. October 2015: version 0.7 (release candidate 4)

Fixed naming strategy for fields that cache values which chose duplicate names.
Fixed resolution of raw types within the type hierarchy which were represented as non-generic TypeDescription instances where type variables of members were not resolved.

Extended public API to accept more general argument types when appropriate.
Extended @Origin annotation to allow for accepting modifiers.

29. April 2015: version 0.6.3

23. April 2015: version 0.6.2

Added additional class validation such that it becomes impossible to define members on classes that do not fit the class's structure, i.e. default methods on Java interfaces in version seven.

Added possibility to write parameter meta information to created classes if it is fully available for a method.

20. March 2015: version 0.5.5

Retrofitted method parameters to be represented by ParameterDescriptions and added possibility to extract names and modifiers for these parameters, either by using the Java 8 API (if available) or by reading this information from the underlying class file.
Fixed a NullPointerException being thrown due to accidental return of a null value from a method.

15. March 2015: version 0.5.4

Fixed missing retention of method annotations of instrumented types.
Allowed dynamic lookup of methods for the MethodCall instrumentation.

24. February 2015: version 0.5.3

Changed the SuperMethodCall instrumentation to fall back to a default method call if required. A different behavior was found to surprise users and would introduce subtle bugs in user code as the super method instrumentation would always work with subclassing due to Java super method call semantics.
Added a MethodCall instrumentation that allows hard-coding a method call.
Added an InvokeDynamic instrumentation that allows runtime dispatching by bootstrap methods.
Fixed the default TypePool to retain generic signatures in order to avoid that agents delete such signatures.

Added additional ElementMatchers that allow to identify class loaders.

5. December 2014: version 0.5.1

3. December 2014: version 0.5

Added the DeclaringTypeResolver as a component in the default chain which selects the most specific method out of two. This is mainly meant to avoid the accidental matching of the methods that are declared by the Object type.
Added TypeInitializers in order to allow Instrumentations to define type initializer blocks.
Replaced the MethodMatcher API with the ElementMatcher API which allows for a more sophisticated matching DSL.
Added a ClassLoadingStrategy for Android in its own module.
Introduced an AgentBuilder API and implementation.

26. November 2014: version 0.4.1

Refactored the implementation of the VoidAwareAssigner which would otherwise cause unexpected behavior in its default state.
Added a missing boxing instruction to the InvocationHandlerAdapter.

18. November 2014: version 0.4

Added proper support for defining class initializers. Added support for field caching from method instrumentations, mainly for allowing the reuse of Method instances for the @Origin annotation and the InvocationHandlerAdapter.

16. June 2014: version 0.2

Changed the semantics of the @SuperCall to be only bindable, if a super method can be invoked. Before, an exception was thrown if only a non-existent or abstract super method was found.
Added features for the interaction with Java 8 default methods. Refactored method lookup to extract invokable default methods.
Refactored the invocation of super methods to be created by an Instrumentation.Target. For a future release, this hopefully allows for class redefinitions using today's API for creating subclasses.
Upgraded to ASM 5.0.3.

02. May 2014: version 0.1

First general release.
