7 - allow users to influence DEFINE and LIBS values.

91.01 Mon May 7 03:00:53 CEST 2012
10 - missing symbols are again exported with a 0 default value.
11 - do not try to use cl_d3d9.h - the d3d9 extension has been abondoned by khronos.
12
131.0 Sat May 5 18:43:54 CEST 2012
14 - OpenCL 1.2 is now effectively feature complete (but hardly tested).
15 - mapping a 1d image with default height now works.
16 - implement these 1.2 functions:
17 $device->sub_devices,
18 $ctx->program_with_built_in_kernels,
19 $ctx->link_program,
20 $program->compile,
21 $kernel->arg_info (and all 5 accessor methods),
22 $queue->migrate_mem_objects.
23 - implement OpenCL::context.
24 - implement $memory->destructor_callback.
25 - new methods: $mappedimage->get_row/set_row/width/height/depth/element_size.
26 - remove $kernel->set_image[23]d.
27 - add most enum and bitfield symbols to the manpage, for quick reference.
28 - default all constants to -1, instead of having them missing.
29 - try hard to get d3d definitions, when/if possible.
30 - add numerical limits and floating point constants from cl_platform.h.
31 - unify C types for accessors, for further code size decrease.
32
330.99 Fri May 4 01:31:15 CEST 2012
34 - OpenCL 1.1 is now effectively feature complete.
35 - work around a bug in the nvidia implementation, where build fails with
36 INVALID_BINARY if the compiler runs succesfully but ptxas fails.
37 - explicitly check for 0 size dimensions in nd_range_kernel, as nvidia
38 crashes (and OpenCL probably allows this behaviour).
39 - actually report clSetKernelArg errors in ("OpenCL::Kernel::setf.
40 - setf properly can now properly set local arguments ('z').
41 - using undef to pass null memory buffers now works in set_xxx.
42 - release_gl_texture was missing.
43 - fix/improve/balance gl sharing example.
44 - added non-opengl sharing opengl example.
45 - fixed some documentation links.
46 - fixed a bug where enqueue operations with optional parameters at the
47 end not specified would crash.
48 - implemented clEnqueueMapBuffer/Image/UnmapMemObject, and a "mapped object"
49 abstraction.
50 - both context_from_type methods now properly pass the notify callback.
51 - $platform->context now properly passes CL_CONTEXT_PLATFORM again.
52 - implement clCreateProgramWithBinary.
53 - speed up object constructions by not looking up stashes.
54 - use libebc for fine-tuning.
55 - reduce codesize considerably by disabling inlining on some functions.
56 - speed up many method calls on objects with no subclasses.
57
580.98 Sat Apr 28 15:31:46 CEST 2012
59 - INCOMPATIBLE CHANGE: $prog->build now wants an array of devices, or undef.
60 - INCOMPATIBLE CHANGE: $queue->enqueue_xxx methods have been renamed to just
61 $queue->xxx, the enqueue_ prefix has been deprecated.
62 - INCOMPATIBLE CHANGE: use ->set_image to set kernel args, ->image[23]d have
63 been deprecated.
64 - new $kernel->setf function to set kernel arguments in one go.
65 - (optional, automatic) anyevent integration.
66 - implement an event queue, use Async::Interrupt for communication.
67 - implement context notification callbacks (untested).
68 - provide a default context notification function that prints to stderr.
69 - implement event callback notifications.
70 - implement build program notifications.
71 - implement an asynchronous program build function.
72 - $ctx->build_program now distinguishes between wrong build invocations
73 and build failures.
74
750.97 Tue Apr 24 16:56:21 CEST 2012
76 - created $ctx->build_program utility function.
77 - enqueue_acquire/release_gl_objects did not return an event object.
78 - OpenCL::errno did not return the correct value.
79 - allow undef values in event wait lists, for convenience.
80 - implement $program->kernels_in_program.
81 - add opencl 1.2 constants.
82 - implement $ctx->image, $ctx->gl_texture, $platform->unload_compiler,
83 $queue->enqueue_fill_buffer/image, all untested (opencl 1.2).
84 - port image2d and image3d to the opencl 1.2 API.
85 - port enqueue_marker/barrier to the opencl 1.2 API, and croak
86 if the user requests something that 1.1 cannot do when compiled
87 against 1.1. This slightly changes the API for enqueue_barrier,
88 which now checks the context it is called in.
89 - add ->format accessor for CL_IMAGHE_FORMAT.
90 - $object->id function to access internal object id.
91
920.96 Fri Apr 20 22:23:58 CEST 2012
93 - ->enqueue_write_buffer actually called enqueue_read_buffer. d'oh.
94 - new $kernel->set_local function, to size local buffer arguments.
95 - use finish, not flush, in examples.
96
970.95 Thu Apr 19 21:25:32 CEST 2012
98 - add lengthy opengl sharing example.
99 - support property lists in CreateContext* calls.
100 - support some opengl sharing extensions
101 (gl_buffer, gl_texture[23]d, gl_renderbuffer).
102 - support some cl_khr_gl_sharing extensions.
103 - add some extension constants (cl_gl.h cl_ext.h, cl_d3d10.h).
104 - auto-generate error codes (and include gl+d3d extensions).
105
1060.92 Mon Apr 16 08:39:21 CEST 2012
107 - work around some bugs in amd's opencl implementation (INVALID_HOST_PTR
108 when value deosn't matter).
12 - minor documentatioon fix (patch by Maik Hentsche). 109 - minor documentation fix (patch by Maik Hentsche).

15 - introduce $buffer_obj->sub_buffer_region method and a new class, OpenCL::BufferObj 112 - introduce $buffer_obj->sub_buffer_region method and a new class, OpenCL::BufferObj
16 for a subbuffer is a buffer without sub_buffer methods! 113 for a subbuffer is a buffer without sub_buffer methods!
17 - support apple using a different location for opencl headers - untested. 114 - support apple using a different location for opencl headers - untested.
