        - enqueue_acquire/release_gl_objects did not return an event object.
        - OpenCL::errno did not return the correct value.
        - allow undef values in event wait lists, for convenience.
        - add opencl 1.2 constants.
        - implement $ctx->gl_texture (1.2).
        - port enqueue_marker/barrier to the opencl 1.2 API, and croak
          if the user requests something that 1.1 cannot do when compiled
          against 1.1. This slightly changes the API for enqueue_barrier,
          which now checks the context it is called in.

0.96 Fri Apr 20 22:23:58 CEST 2012
        - ->enqueue_write_buffer actually called enqueue_read_buffer. d'oh.
        - new $kernel->set_local function, to size local buffer arguments.
        - use finish, not flush, in examples.

0.95 Thu Apr 19 21:25:32 CEST 2012
        - add lengthy opengl sharing example.
        - support property lists in CreateContext* calls.
        - support some opengl sharing extensions
          (gl_buffer, gl_texture[23]d, gl_renderbuffer).
        - support some cl_khr_gl_sharing extensions.
        - add some extension constants (cl_gl.h cl_ext.h, cl_d3d10.h).
        - auto-generate error codes (and include gl+d3d extensions).

0.92 Mon Apr 16 08:39:21 CEST 2012
        - work around some bugs in amd's opencl implementation (INVALID_HOST_PTR
          when value deosn't matter).
        - minor documentation fix (patch by Maik Hentsche).

0.91 Sun Dec 11 00:05:02 CET 2011
        - introduce $buffer_obj->sub_buffer_region method and a new class, OpenCL::BufferObj
          for a subbuffer is a buffer without sub_buffer methods!
        - support apple using a different location for opencl headers - untested.
        - be more strict when passing event lists.

0.59 Tue Nov 22 11:44:32 CET 2011
        - provide $program->binaries method.
        - provide $queue->enqueue_read_buffer_rect method.
        - provide $queue->enqueue_write_buffer_rect method.
        - coalesce like-typed accessor methods into the same xs function and
          multiple ALIASes - this reduces the OpenCL codesize from 162kb to
          132kb on my system.
        - minor doc improvements.

0.55 Sun Nov 20 11:19:25 CET 2011
        - semi-automatically generate query methods for almost all clGet*Info names.
        - provide cl_ext.h constants.
        - provide OpenCL::Image->image_info method.
        - provide OpenCL::Event->profiling_info method.
        - provide OpenCL::Kernel->work_group_info method.

0.15 Thu Nov 17 07:22:11 CET 2011
        - include slice_pitch in enqueue_write_image (can be 0).
        - check length in enqueue_write_image.
        - properly calculate size in enqueue_read_image.
        - likewise, include row_pitch and slice_pitch in image2d and image3d,
          which must be nonzero right now, too, sorry.
        - allow undef or missing data scalar for image2d and image3d.
        - fix enqueue_copy_image prototype.
        - fix formatting.

0.14 Thu Nov 17 04:04:23 CET 2011
        - major incompatibilities due to API cleanup, the API should now be
          mostly stable, if incomplete.
        - fix prerequisites.
        - replaced all _simple functions by "full" implementations, with some
          parameters marked for future expansion - that means their API
          should be stable from now on:
             OpenCL::context_from_type_simple    => OpenCL::context_from_type
             $platform->context_from_type_simple => $platform->context_from_type
             $dev->context_simple                => $platform->context
             $ctx->command_queue_simple became   => $ctx->queue
        - add OpenCL::context function.
        - officially require C99.
        - errno value is unspecified after a successful call.

0.03  Wed Nov 16 01:44:26 CET 2011
        - add some reference documentation for all functions.
        - add user event support.
        - implement event wait lists.

0.02  Tue Nov 15 22:15:47 CET 2011
        - first opencl kernel executed, some example code.

0.01  Tue Nov 15 05:59:00 CET 2011
        - cloned from Convert::Scalar.
