### 19. April 2016: version 1.3.14

- General API improvements and minor bug fixes.

### 4. January 2016: version 0.7.8

- Fixed type resolution for anonymously loaded classes by the `ClassReloadingStrategy`.
- Added additional `InitiailizationStrategy`s for self-injection where the new default strategy loads types that are independent of the instrumented type before completing the instrumentation.

- Fallback to no allowing for instrumenting type initializers for rebased or redefined interfaces before Java 8.

### 28. October 2015: version 0.7 (release candidate 6)

- 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.

- Fixed class file parser which would not recognize outer classes for version 1.3 byte code.

### 6. October 2015: version 0.7 (release candidate 3)

- Changed modifiers for accessor methods and rebased methods to be public when rebasing or accessing methods of a Java 8 interface. For interfaces, all modifiers must be public, even for such synthetic members.
- Support absolute path names for accessing class file resources of the `ByteArrayClassLoader`.

Corrected incorrect deployment of version 0.6.7 which does not use a dependency reduced POM for the *byte-buddy* module.

### 1. June 2015: version 0.6.8 (and 0.6.7)

- Upgraded ASM dependency to 5.0.4.
- Fixed OSGi headers in all relevant artifacts.

*Warning*: The *byte-buddy* artifact of version 0.6.7 is accidentally deployed with a defect POM file which does not exclude the shaded resources.

  loaders would have been considered inequal what is not true for the byte code level.

### 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 default `Assigner` singleton.

- 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 `ParameterDescription`s 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.

### 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

  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.

### 18. January 2015: version 0.5.2

- Fixed a bug where interface generation would result in a `NullPointerException`.
- Added additional `ElementMatcher`s that allow to identify class loaders.

### 5. December 2014: version 0.5.1

Added the `andThen` method to the `SuperMethodCall` instrumentation in order to allow for a more convenient
executingTransformer interception where a hard-coded super method call is required by the Java verifier.

### 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 `TypeInitializer`s in order to allow `Instrumentation`s to define type initializer blocks.
- Replaced the `MethodMatcher` API with the `ElementMatcher` API which allows for a more sophisticated matching DSL.

- 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.

- Extended `Instrumentation.Context` to support field accessors.
- Added the `TypePool` abstraction and added a default implementation.
- Refactored annotations to have an intermediate form as `AnnotationDescription` which does not need to
  represent loaded values.
- Refactored several built-in `Instrumentation`, among others, all implementations now support `TypeDescription`
  in addition to loaded `Class` as their arguments

  class loading strategies.

### 20. June 2014: version 0.2.1

- 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.
