7 - do not try to include cl_d3d9.h - it seems to have been removed
8 from the repository, and not reliably available.

101.0 Sat May 5 18:43:54 CEST 2012
11 - OpenCL 1.2 is now effectively feature complete (but hardly tested).
12 - mapping a 1d image with default height now works.
13 - implement these 1.2 functions:
14 $device->sub_devices,
15 $ctx->program_with_built_in_kernels,
16 $ctx->link_program,
17 $program->compile,
18 $kernel->arg_info (and all 5 accessor methods),
19 $queue->migrate_mem_objects.
20 - implement OpenCL::context.
21 - implement $memory->destructor_callback.
22 - new methods: $mappedimage->get_row/set_row/width/height/depth/element_size.
23 - remove $kernel->set_image[23]d.
24 - add most enum and bitfield symbols to the manpage, for quick reference.
25 - default all constants to -1, instead of having them missing.
26 - try hard to get d3d definitions, when/if possible.
27 - add numerical limits and floating point constants from cl_platform.h.
28 - unify C types for accessors, for further code size decrease.

300.99 Fri May 4 01:31:15 CEST 2012
31 - OpenCL 1.1 is now effectively feature complete.
32 - work around a bug in the nvidia implementation, where build fails with
33 INVALID_BINARY if the compiler runs succesfully but ptxas fails.
34 - explicitly check for 0 size dimensions in nd_range_kernel, as nvidia
35 crashes (and OpenCL probably allows this behaviour).
36 - actually report clSetKernelArg errors in ("OpenCL::Kernel::setf.
37 - setf properly can now properly set local arguments ('z').
38 - using undef to pass null memory buffers now works in set_xxx.
39 - release_gl_texture was missing.
40 - fix/improve/balance gl sharing example.
41 - added non-opengl sharing opengl example.
42 - fixed some documentation links.
43 - fixed a bug where enqueue operations with optional parameters at the
44 end not specified would crash.
45 - implemented clEnqueueMapBuffer/Image/UnmapMemObject, and a "mapped object"
46 abstraction.
47 - both context_from_type methods now properly pass the notify callback.
48 - $platform->context now properly passes CL_CONTEXT_PLATFORM again.
49 - implement clCreateProgramWithBinary.
50 - speed up object constructions by not looking up stashes.
51 - use libebc for fine-tuning.
52 - reduce codesize considerably by disabling inlining on some functions.
53 - speed up many method calls on objects with no subclasses.
54
550.98 Sat Apr 28 15:31:46 CEST 2012
56 - INCOMPATIBLE CHANGE: $prog->build now wants an array of devices, or undef.
57 - INCOMPATIBLE CHANGE: $queue->enqueue_xxx methods have been renamed to just
58 $queue->xxx, the enqueue_ prefix has been deprecated.
59 - INCOMPATIBLE CHANGE: use ->set_image to set kernel args, ->image[23]d have
60 been deprecated.
61 - new $kernel->setf function to set kernel arguments in one go.
62 - (optional, automatic) anyevent integration.
63 - implement an event queue, use Async::Interrupt for communication.
64 - implement context notification callbacks (untested).
65 - provide a default context notification function that prints to stderr.
66 - implement event callback notifications.
67 - implement build program notifications.
68 - implement an asynchronous program build function.
69 - $ctx->build_program now distinguishes between wrong build invocations
70 and build failures.
71
720.97 Tue Apr 24 16:56:21 CEST 2012
73 - created $ctx->build_program utility function.
74 - enqueue_acquire/release_gl_objects did not return an event object.
75 - OpenCL::errno did not return the correct value.
76 - allow undef values in event wait lists, for convenience.
77 - implement $program->kernels_in_program.
78 - add opencl 1.2 constants.
79 - implement $ctx->image, $ctx->gl_texture, $platform->unload_compiler,
80 $queue->enqueue_fill_buffer/image, all untested (opencl 1.2).
81 - port image2d and image3d to the opencl 1.2 API.
82 - port enqueue_marker/barrier to the opencl 1.2 API, and croak
83 if the user requests something that 1.1 cannot do when compiled
84 against 1.1. This slightly changes the API for enqueue_barrier,
85 which now checks the context it is called in.
86 - add ->format accessor for CL_IMAGHE_FORMAT.
87 - $object->id function to access internal object id.
88
890.96 Fri Apr 20 22:23:58 CEST 2012
90 - ->enqueue_write_buffer actually called enqueue_read_buffer. d'oh.
91 - new $kernel->set_local function, to size local buffer arguments.
92 - use finish, not flush, in examples.
93
940.95 Thu Apr 19 21:25:32 CEST 2012
95 - add lengthy opengl sharing example.
96 - support property lists in CreateContext* calls.
97 - support some opengl sharing extensions
98 (gl_buffer, gl_texture[23]d, gl_renderbuffer).
99 - support some cl_khr_gl_sharing extensions.
100 - add some extension constants (cl_gl.h cl_ext.h, cl_d3d10.h).
101 - auto-generate error codes (and include gl+d3d extensions).

14 when value deosn't matter). 105 when value deosn't matter).
15 - minor documentation fix (patch by Maik Hentsche). 106 - minor documentation fix (patch by Maik Hentsche).
