## 1.10.0

* If statements with empty blocks and comparisons outside of if or while statements now compile and run on the GPU.
* Fix kernel management inconsistencies regarding preferred devices management
* Fix Java execution mode with barriers to not deadlock when a thread dies or is interrupted (InterruptedException)

* Java execution mode now provides detailed backtraces of failed Kernel threads including passId, groupIds, globalIds and localIds
* Internal translation of bytecode is now facilitated by the BCEL library
* Scala support has been added (see unit tests).
* Fix arrays of AtomicInteger stored on local variables no longer fail with type cast exception while generating OpenCL (support for I_ALOAD_0,1,2,3 bytecode instructions)

## 1.9.0

* Fixed local arrays handling 1D and ND, to cope with arrays resizing across kernel executions
* Significant speed-up on discrete GPUs with dedicated memory - OpenCLDevice.setSharedMemory(false)
* Now supports efficient execution on discrete GPU and other devices with dedicated memory
* Support for OpenCLDevice configurator/configure API

## 1.8.0

* Updated KernelManager to facilitate class extensions having constructors with non static parameters

* Fixed bug where signed integer constants were being interpreted as unsigned values during Codegen.

## 1.7.0

* Fully support barrier() - localBarrier(),  globalBarrier() and localGlobalBarrier() on OpenCL 1.2 and later.
* Improved exception handling, stack traces no longer double print and Error and other throwables are never caught.
* Fix issue causing SEVERE log messages on Aparapi kernel profiling under multithreading.
* Provide new interfaces for thread safe kernel profiling (mutiple threads calling same kernel class on same device).
* Fixed occasional deadlock in JTP execution mode.
* Significant speedup when running in JTP execution mode.

## 1.6.0

* Added support for Local arguments in kernel functions
* Added full support for atomic operations of arrays of integers on OpenCL 1.2 and later.

## 1.5.0

* Support for OpenCL 2.1 added.
* Support inline array creation in the kernel, which is implemented in the GPU in private memory.
* Updated parent pom to v6.
* createProgram had the wrong signature producing a unsatisfied link exception that is now fixed.
* Build now requires version 3.5.0 of maven due to changes in surefire plugin.
* Added the functions popcount and clz

## 1.4.1

* Fixed NullPointerException when using KernelManger from the KernelManagers class
* Now requires maven 3.0.4 or later.
* Bumped parent pom version to 4.
* Removed explicit versions from several plugins in the pom as these are defined in the parent.

## 1.4.0

* Updated nexus staging plugin: 1.6.7 -> 1.6.8
* Added Fused Multiply Add support.
* Fixed a bug whereby the library failed to load if OpenCL implementation isnt present, system now loads and falls back to native Java.
* Fixed several mistakes and typos in the various examples.

## 1.3.4

* Updated to aparapi-jni 1.1.2 thus fixing `UnsatisfiedLinkError` which occured only on Windows.
