7 - (xthread) work around compile time bugs in ptw32.
8 - allow users to influence DEFINE and LIBS values.
9 - example context selection wasn't very robust in the presence
10 of multiple platforms.
11 - fix compilation on win32 (patch by Karel Miko).

131.01 Mon May 7 03:00:53 CEST 2012
14 - missing symbols are again exported with a 0 default value.
15 - do not try to use cl_d3d9.h - the d3d9 extension has been abondoned by khronos.
16
171.0 Sat May 5 18:43:54 CEST 2012
18 - OpenCL 1.2 is now effectively feature complete (but hardly tested).
19 - mapping a 1d image with default height now works.
20 - implement these 1.2 functions:
21 $device->sub_devices,
22 $ctx->program_with_built_in_kernels,
23 $ctx->link_program,
24 $program->compile,
25 $kernel->arg_info (and all 5 accessor methods),
26 $queue->migrate_mem_objects.
27 - implement OpenCL::context.
28 - implement $memory->destructor_callback.
29 - new methods: $mappedimage->get_row/set_row/width/height/depth/element_size.
30 - remove $kernel->set_image[23]d.
31 - add most enum and bitfield symbols to the manpage, for quick reference.
32 - default all constants to -1, instead of having them missing.
33 - try hard to get d3d definitions, when/if possible.
34 - add numerical limits and floating point constants from cl_platform.h.
35 - unify C types for accessors, for further code size decrease.
36
370.99 Fri May 4 01:31:15 CEST 2012
38 - OpenCL 1.1 is now effectively feature complete.
39 - work around a bug in the nvidia implementation, where build fails with
40 INVALID_BINARY if the compiler runs succesfully but ptxas fails.
41 - explicitly check for 0 size dimensions in nd_range_kernel, as nvidia
42 crashes (and OpenCL probably allows this behaviour).
43 - actually report clSetKernelArg errors in ("OpenCL::Kernel::setf.
44 - setf properly can now properly set local arguments ('z').
45 - using undef to pass null memory buffers now works in set_xxx.
46 - release_gl_texture was missing.
47 - fix/improve/balance gl sharing example.
48 - added non-opengl sharing opengl example.
49 - fixed some documentation links.
50 - fixed a bug where enqueue operations with optional parameters at the
51 end not specified would crash.
52 - implemented clEnqueueMapBuffer/Image/UnmapMemObject, and a "mapped object"
53 abstraction.
54 - both context_from_type methods now properly pass the notify callback.
55 - $platform->context now properly passes CL_CONTEXT_PLATFORM again.
56 - implement clCreateProgramWithBinary.
57 - speed up object constructions by not looking up stashes.
58 - use libebc for fine-tuning.
59 - reduce codesize considerably by disabling inlining on some functions.
60 - speed up many method calls on objects with no subclasses.
61
620.98 Sat Apr 28 15:31:46 CEST 2012
63 - INCOMPATIBLE CHANGE: $prog->build now wants an array of devices, or undef.
64 - INCOMPATIBLE CHANGE: $queue->enqueue_xxx methods have been renamed to just
65 $queue->xxx, the enqueue_ prefix has been deprecated.
66 - INCOMPATIBLE CHANGE: use ->set_image to set kernel args, ->image[23]d have
67 been deprecated.
68 - new $kernel->setf function to set kernel arguments in one go.
69 - (optional, automatic) anyevent integration.
70 - implement an event queue, use Async::Interrupt for communication.
71 - implement context notification callbacks (untested).
72 - provide a default context notification function that prints to stderr.
73 - implement event callback notifications.
74 - implement build program notifications.
75 - implement an asynchronous program build function.
76 - $ctx->build_program now distinguishes between wrong build invocations
77 and build failures.

790.97 Tue Apr 24 16:56:21 CEST 2012
80 - created $ctx->build_program utility function.
12 - enqueue_acquire/release_gl_objects did not return an event object. 81 - enqueue_acquire/release_gl_objects did not return an event object.
13 - OpenCL::errno did not return the correct value. 82 - OpenCL::errno did not return the correct value.
14 - allow undef values in event wait lists, for convenience. 83 - allow undef values in event wait lists, for convenience.
84 - implement $program->kernels_in_program.
15 - add opencl 1.2 constants. 85 - add opencl 1.2 constants.
16 - implement $ctx->gl_texture (1.2). 86 - implement $ctx->image, $ctx->gl_texture, $platform->unload_compiler,
87 $queue->enqueue_fill_buffer/image, all untested (opencl 1.2).
88 - port image2d and image3d to the opencl 1.2 API.
17 - port enqueue_marker/barrier to the opencl 1.2 API, and croak 89 - port enqueue_marker/barrier to the opencl 1.2 API, and croak
18 if the user requests something that 1.1 cannot do when compiled 90 if the user requests something that 1.1 cannot do when compiled
19 against 1.1. This slightly changes the API for enqueue_barrier, 91 against 1.1. This slightly changes the API for enqueue_barrier,
20 which now checks the context it is called in. 92 which now checks the context it is called in.
93 - add ->format accessor for CL_IMAGHE_FORMAT.
94 - $object->id function to access internal object id.

23 - ->enqueue_write_buffer actually called enqueue_read_buffer. d'oh. 97 - ->enqueue_write_buffer actually called enqueue_read_buffer. d'oh.
24 - new $kernel->set_local function, to size local buffer arguments. 98 - new $kernel->set_local function, to size local buffer arguments.
25 - use finish, not flush, in examples. 99 - use finish, not flush, in examples.
