11TODO: context (FUTURE properties, FUTURE devices, FUTURE notify)
12 - implement $queue->migrate_mem_objects.
13 - implement $ctx->program_with_built_in_kernels.
14 - implement $device->sub_devices.
15 - add most enum and bitfield symbols to the manpage, for quick reference.

18 - OpenCL 1.1 is now effectively feature complete.
19 - work around a bug in the nvidia implementation, where build fails with
20 INVALID_BINARY if the compiler runs succesfully but ptxas fails.
21 - explicitly check for 0 size dimensions in nd_range_kernel, as nvidia
22 crashes (and OpenCL probably allows this behaviour).
23 - actually report clSetKernelArg errors in ("OpenCL::Kernel::setf.
24 - setf properly can now properly set local arguments ('z').
25 - using undef to pass null memory buffers now works in set_xxx.
26 - release_gl_texture was missing.
27 - fix/improve/balance gl sharing example.
28 - added non-opengl sharing opengl example.
29 - fixed some documentation links.
30 - fixed a bug where enqueue operations with optional parameters at the
31 end not specified would crash.
32 - implemented clEnqueueMapBuffer/Image/UnmapMemObject, and a "mapped object"
33 abstraction.
34 - both context_from_type methods now properly pass the notify callback.
35 - $platform->context now properly passes CL_CONTEXT_PLATFORM again.
36 - implement clCreateProgramWithBinary.
37 - speed up object constructions by not looking up stashes.
38 - use libebc for fine-tuning.
39 - reduce codesize considerably by disabling inlining on some functions.
40 - speed up many method calls on objects with no subclasses.

420.98 Sat Apr 28 15:31:46 CEST 2012
43 - INCOMPATIBLE CHANGE: $prog->build now wants an array of devices, or undef.
44 - INCOMPATIBLE CHANGE: $queue->enqueue_xxx methods have been renamed to just
45 $queue->xxx, the enqueue_ prefix has been deprecated.
46 - INCOMPATIBLE CHANGE: use ->set_image to set kernel args, ->image[23]d have
47 been deprecated.
48 - new $kernel->setf function to set kernel arguments in one go.
49 - (optional, automatic) anyevent integration.
50 - implement an event queue, use Async::Interrupt for communication.
51 - implement context notification callbacks (untested).
52 - provide a default context notification function that prints to stderr.
53 - implement event callback notifications.
54 - implement build program notifications.
55 - implement an asynchronous program build function.
56 - $ctx->build_program now distinguishes between wrong build invocations
57 and build failures.
58
590.97 Tue Apr 24 16:56:21 CEST 2012
60 - created $ctx->build_program utility function.
61 - enqueue_acquire/release_gl_objects did not return an event object.
62 - OpenCL::errno did not return the correct value.
63 - allow undef values in event wait lists, for convenience.
64 - implement $program->kernels_in_program.
65 - add opencl 1.2 constants.
66 - implement $ctx->image, $ctx->gl_texture, $platform->unload_compiler,
67 $queue->enqueue_fill_buffer/image, all untested (opencl 1.2).
68 - port image2d and image3d to the opencl 1.2 API.
69 - port enqueue_marker/barrier to the opencl 1.2 API, and croak
70 if the user requests something that 1.1 cannot do when compiled
71 against 1.1. This slightly changes the API for enqueue_barrier,
72 which now checks the context it is called in.
73 - add ->format accessor for CL_IMAGHE_FORMAT.
74 - $object->id function to access internal object id.
75
760.96 Fri Apr 20 22:23:58 CEST 2012
77 - ->enqueue_write_buffer actually called enqueue_read_buffer. d'oh.
78 - new $kernel->set_local function, to size local buffer arguments.
79 - use finish, not flush, in examples.
80
810.95 Thu Apr 19 21:25:32 CEST 2012
82 - add lengthy opengl sharing example.
83 - support property lists in CreateContext* calls.
84 - support some opengl sharing extensions
85 (gl_buffer, gl_texture[23]d, gl_renderbuffer).
86 - support some cl_khr_gl_sharing extensions.
87 - add some extension constants (cl_gl.h cl_ext.h, cl_d3d10.h).
88 - auto-generate error codes (and include gl+d3d extensions).
89
900.92 Mon Apr 16 08:39:21 CEST 2012
91 - work around some bugs in amd's opencl implementation (INVALID_HOST_PTR
92 when value deosn't matter).
93 - minor documentation fix (patch by Maik Hentsche).
94
950.91 Sun Dec 11 00:05:02 CET 2011
96 - introduce $buffer_obj->sub_buffer_region method and a new class, OpenCL::BufferObj
97 for a subbuffer is a buffer without sub_buffer methods!
98 - support apple using a different location for opencl headers - untested.
99 - be more strict when passing event lists.
