15 - OpenCL 1.1 is now effectively feature complete.
16 - work around a bug in the nvidia implementation, where build fails with
17 INVALID_BINARY if the compiler runs succesfully but ptxas fails.
18 - explicitly check for 0 size dimensions in nd_range_kernel, as nvidia
19 crashes (and OpenCL probably allows this behaviour).
20 - actually report clSetKernelArg errors in ("OpenCL::Kernel::setf.
21 - setf properly can now properly set local arguments ('z').
22 - using undef to pass null memory buffers now works in set_xxx.
23 - release_gl_texture was missing.
24 - fix/improve/balance gl sharing example.
25 - added non-opengl sharing opengl example.
26 - fixed some documentation links.
27 - fixed a bug where enqueue operations with optional parameters at the
28 end not specified would crash.
29 - implemented clEnqueueMapBuffer/Image/UnmapMemObject, and a "mapped object"
30 abstraction.
31 - both context_from_type methods now properly pass the notify callback.
32 - $platform->context now properly passes CL_CONTEXT_PLATFORM again.
33 - implement clCreateProgramWithBinary.
34 - speed up object constructions by not looking up stashes.
35 - use libebc for fine-tuning.
36 - reduce codesize considerably by disabling inlining on some functions.
37 - speed up many method calls on objects with no subclasses.
38
390.98 Sat Apr 28 15:31:46 CEST 2012
40 - INCOMPATIBLE CHANGE: $prog->build now wants an array of devices, or undef.
41 - INCOMPATIBLE CHANGE: $queue->enqueue_xxx methods have been renamed to just
42 $queue->xxx, the enqueue_ prefix has been deprecated.
43 - INCOMPATIBLE CHANGE: use ->set_image to set kernel args, ->image[23]d have
44 been deprecated.
45 - new $kernel->setf function to set kernel arguments in one go.
46 - (optional, automatic) anyevent integration.
47 - implement an event queue, use Async::Interrupt for communication.
48 - implement context notification callbacks (untested).
49 - provide a default context notification function that prints to stderr.
50 - implement event callback notifications.
51 - implement build program notifications.
52 - implement an asynchronous program build function.
53 - $ctx->build_program now distinguishes between wrong build invocations
54 and build failures.
55
560.97 Tue Apr 24 16:56:21 CEST 2012
57 - created $ctx->build_program utility function.
58 - enqueue_acquire/release_gl_objects did not return an event object.
59 - OpenCL::errno did not return the correct value.
60 - allow undef values in event wait lists, for convenience.
61 - implement $program->kernels_in_program.
62 - add opencl 1.2 constants.
63 - implement $ctx->image, $ctx->gl_texture, $platform->unload_compiler,
64 $queue->enqueue_fill_buffer/image, all untested (opencl 1.2).
65 - port image2d and image3d to the opencl 1.2 API.
66 - port enqueue_marker/barrier to the opencl 1.2 API, and croak
67 if the user requests something that 1.1 cannot do when compiled
68 against 1.1. This slightly changes the API for enqueue_barrier,
69 which now checks the context it is called in.
70 - add ->format accessor for CL_IMAGHE_FORMAT.
71 - $object->id function to access internal object id.
72
730.96 Fri Apr 20 22:23:58 CEST 2012
74 - ->enqueue_write_buffer actually called enqueue_read_buffer. d'oh.
75 - new $kernel->set_local function, to size local buffer arguments.
76 - use finish, not flush, in examples.
77
780.95 Thu Apr 19 21:25:32 CEST 2012
79 - add lengthy opengl sharing example.
80 - support property lists in CreateContext* calls.
81 - support some opengl sharing extensions
82 (gl_buffer, gl_texture[23]d, gl_renderbuffer).
83 - support some cl_khr_gl_sharing extensions.
84 - add some extension constants (cl_gl.h cl_ext.h, cl_d3d10.h).
85 - auto-generate error codes (and include gl+d3d extensions).
86
870.92 Mon Apr 16 08:39:21 CEST 2012
88 - work around some bugs in amd's opencl implementation (INVALID_HOST_PTR
89 when value deosn't matter).
90 - minor documentation fix (patch by Maik Hentsche).
91
920.91 Sun Dec 11 00:05:02 CET 2011
93 - introduce $buffer_obj->sub_buffer_region method and a new class, OpenCL::BufferObj
94 for a subbuffer is a buffer without sub_buffer methods!
95 - support apple using a different location for opencl headers - untested.
96 - be more strict when passing event lists.
97
980.59 Tue Nov 22 11:44:32 CET 2011
10 - added $program->binaries method. 99 - provide $program->binaries method.
100 - provide $queue->enqueue_read_buffer_rect method.
101 - provide $queue->enqueue_write_buffer_rect method.
11 - coalesce like-typed accessor methods into the same xs function and 102 - coalesce like-typed accessor methods into the same xs function and
12 multiple ALIASes - this reduces the OpenCL codesize from 162kb to 103 multiple ALIASes - this reduces the OpenCL codesize from 162kb to
13 132kb on my system. 104 132kb on my system.
