71.01 Mon May 7 03:00:53 CEST 2012
8 - missing symbols are again exported with a 0 default value.
9 - do not try to use cl_d3d9.h - the d3d9 extension has been abondoned by khronos.

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

310.99 Fri May 4 01:31:15 CEST 2012
32 - OpenCL 1.1 is now effectively feature complete.
33 - work around a bug in the nvidia implementation, where build fails with
34 INVALID_BINARY if the compiler runs succesfully but ptxas fails.
35 - explicitly check for 0 size dimensions in nd_range_kernel, as nvidia
36 crashes (and OpenCL probably allows this behaviour).
37 - actually report clSetKernelArg errors in ("OpenCL::Kernel::setf.
38 - setf properly can now properly set local arguments ('z').
39 - using undef to pass null memory buffers now works in set_xxx.
40 - release_gl_texture was missing.
41 - fix/improve/balance gl sharing example.
42 - added non-opengl sharing opengl example.
43 - fixed some documentation links.
44 - fixed a bug where enqueue operations with optional parameters at the
45 end not specified would crash.
46 - implemented clEnqueueMapBuffer/Image/UnmapMemObject, and a "mapped object"
47 abstraction.
48 - both context_from_type methods now properly pass the notify callback.
49 - $platform->context now properly passes CL_CONTEXT_PLATFORM again.
50 - implement clCreateProgramWithBinary.
51 - speed up object constructions by not looking up stashes.
52 - use libebc for fine-tuning.
53 - reduce codesize considerably by disabling inlining on some functions.
54 - speed up many method calls on objects with no subclasses.
55
560.98 Sat Apr 28 15:31:46 CEST 2012
57 - INCOMPATIBLE CHANGE: $prog->build now wants an array of devices, or undef.
58 - INCOMPATIBLE CHANGE: $queue->enqueue_xxx methods have been renamed to just
59 $queue->xxx, the enqueue_ prefix has been deprecated.
60 - INCOMPATIBLE CHANGE: use ->set_image to set kernel args, ->image[23]d have
61 been deprecated.
62 - new $kernel->setf function to set kernel arguments in one go.
63 - (optional, automatic) anyevent integration.
64 - implement an event queue, use Async::Interrupt for communication.
65 - implement context notification callbacks (untested).
66 - provide a default context notification function that prints to stderr.
67 - implement event callback notifications.
68 - implement build program notifications.
69 - implement an asynchronous program build function.
70 - $ctx->build_program now distinguishes between wrong build invocations
71 and build failures.
72
730.97 Tue Apr 24 16:56:21 CEST 2012
74 - created $ctx->build_program utility function.
75 - enqueue_acquire/release_gl_objects did not return an event object.
76 - OpenCL::errno did not return the correct value.
77 - allow undef values in event wait lists, for convenience.
78 - implement $program->kernels_in_program.
79 - add opencl 1.2 constants.
80 - implement $ctx->image, $ctx->gl_texture, $platform->unload_compiler,
81 $queue->enqueue_fill_buffer/image, all untested (opencl 1.2).
82 - port image2d and image3d to the opencl 1.2 API.
83 - port enqueue_marker/barrier to the opencl 1.2 API, and croak
84 if the user requests something that 1.1 cannot do when compiled
85 against 1.1. This slightly changes the API for enqueue_barrier,
86 which now checks the context it is called in.
87 - add ->format accessor for CL_IMAGHE_FORMAT.
88 - $object->id function to access internal object id.
89
900.96 Fri Apr 20 22:23:58 CEST 2012
91 - ->enqueue_write_buffer actually called enqueue_read_buffer. d'oh.
92 - new $kernel->set_local function, to size local buffer arguments.
93 - use finish, not flush, in examples.
94
950.95 Thu Apr 19 21:25:32 CEST 2012
96 - add lengthy opengl sharing example.
97 - support property lists in CreateContext* calls.
98 - support some opengl sharing extensions
99 (gl_buffer, gl_texture[23]d, gl_renderbuffer).
100 - support some cl_khr_gl_sharing extensions.
101 - add some extension constants (cl_gl.h cl_ext.h, cl_d3d10.h).
102 - auto-generate error codes (and include gl+d3d extensions).
103
1040.92 Mon Apr 16 08:39:21 CEST 2012
105 - work around some bugs in amd's opencl implementation (INVALID_HOST_PTR
106 when value deosn't matter).
107 - minor documentation fix (patch by Maik Hentsche).
108
1090.91 Sun Dec 11 00:05:02 CET 2011
10 - introduce $buffer_obj->sub_buffer_region method and a new class, OpenCL::BufferObj 110 - introduce $buffer_obj->sub_buffer_region method and a new class, OpenCL::BufferObj
11 for a subbuffer is a buffer without sub_buffer methods! 111 for a subbuffer is a buffer without sub_buffer methods!
12 - support apple using a different location for opencl headers - untested. 112 - support apple using a different location for opencl headers - untested.
113 - be more strict when passing event lists.

15 - provide $program->binaries method. 116 - provide $program->binaries method.
16 - provide $queue->enqueue_read_buffer_rect method. 117 - provide $queue->enqueue_read_buffer_rect method.
17 - provide $queue->enqueue_write_buffer_rect method. 118 - provide $queue->enqueue_write_buffer_rect method.
