4 ChangeLog
5
6 0.9.0 2020-12-17 A Winter'20 release.
7
8 0.6.2 2019-03-24 A Spring'20 release.
9
10 Fixed compile errors on macOS.
11
12 Expose actual system error codes via client interface
13 instead of just -1 whenever a syscall failed.
14
15 Added new client interface function:
16 lscp_client_connection_lost();
17 for checking whether client lost connection to server.
18
19 Fixed potential missing NULL termination of locale strings.
20
21 0.6.1 2019-12-22 The Winter'19 Release.
22
23 0.6.0 2017-12-12 An Autumn'17 release.
24
25 0.5.8 2016-11-14 A Fall'16 release.
26
27 0.5.7 2013-12-31 Use getaddrinfo() instead of deprecated gethostbyname().
28
29 Update on newer autoconf macros (m4).
30
31 Fixes for building for Windows with configure and make.
32
33 Makefile fixes for building in separate directory.
34
35 Autoconf fix: AC_CONFIG_HEADER obsolete error (fixes #194).
36
37 0.5.6 2009-08-01 Fixed locale related parser bug (fixes #59).
38
39 Added new client interface functions, for managing
40 the global limit of maximum voices and disk streams:
41 lscp_get_voices(), lscp_set_voices(), lscp_get_streams(),
42 lscp_set_streams().
43
44 _lscp_device_port_info_query(): take port parameter
45 "NAME" into the result list.
46
47 Bugfix: _lscp_client_evt_proc() dropped LSCP events.
48
49 Bugfix in lscp_client_subscribe(): only the first
50 lscp_client_subscribe() call succeeded (per client),
51 all subsequent ones failed.
52
53 Added support for new (un)subscribable events:
54 LSCP_EVENT_CHANNEL_MIDI
55 LSCP_EVENT_DEVICE_MIDI
56 Caution: the bitflag approach for the event variable
57 is now abondoned, since otherwise we would soon hit the
58 limit of the bit range. The bitflag approach will
59 remain for events older at this point (that is all
60 events which occupy the lower 16 bits), but this new
61 and all following events will simply be enumared along
62 the upper 16 bits.
63
64 Added new client interface function, for renaming
65 effect send entities:
66 lscp_set_fxsend_name();
67
68 Added new client interface functions, for managing the
69 global limit of maximum voices and disk streams:
70 lscp_get_voices();
71 lscp_set_voices();
72 lscp_get_streams();
73 lscp_set_streams();
74
75 Bugfix: fixed buggy behavior on different locale
76 settings (e.g. when parsing floating point numbers).
77
78 0.5.5 2007-10-12 Changed client interface function, for editing
79 instrument, from:
80 lscp_edit_instrument();
81 to:
82 lscp_edit_channel_instrument();
83
84 0.5.4 2007-10-02 Added new client interface function, for editing
85 instrument:
86 lscp_edit_instrument();
87
88 Fixed some minor bugs in:
89 lscp_set_fxsend_midi_controller();
90 lscp_set_fxsend_level();
91
92 0.5.3 2007-01-15 Added new client interface functions, for sampler
93 channel effect sends control:
94 lscp_set_fxsend_midi_controller();
95 lscp_set_fxsend_level();
96
97 Added new field member to lscp_fxsend_info_t (level).
98
99 0.5.2 2007-01-11 Added new client interface functions, for sampler
100 channel effect sends control:
101 lscp_create_fxsend();
102 lscp_destroy_fxsend();
103 lscp_get_fxsends();
104 lscp_list_fxsends();
105 lscp_get_fxsend_info();
106 lscp_set_fxsend_audio_channel();
107 and for global volume:
108 lscp_get_volume();
109 lscp_set_volume();
110
111 Audio routing representation changed to integer array.
112
113 0.5.1 2006-12-22 Added support for new (un)subscribable events:
114 LSCP_EVENT_AUDIO_OUTPUT_DEVICE_COUNT,
115 LSCP_EVENT_AUDIO_OUTPUT_DEVICE_INFO,
116 LSCP_EVENT_MIDI_INPUT_DEVICE_COUNT,
117 LSCP_EVENT_MIDI_INPUT_DEVICE_INFO,
118 LSCP_EVENT_MIDI_INSTRUMENT_MAP_COUNT,
119 LSCP_EVENT_MIDI_INSTRUMENT_MAP_INFO,
120 LSCP_EVENT_MIDI_INSTRUMENT_COUNT,
121 LSCP_EVENT_MIDI_INSTRUMENT_INFO.
122
123 Updated examples.
124
125 0.5.0 2006-12-17 MIDI instrument mapping, second round, according to
126 LSCP 1.2 draft document as of December 15, 2006.
127
128 New client interface functions:
129 lscp_set_channel_midi_map();
130 lscp_add_midi_instrument_map();
131 lscp_remove_midi_instrument_map();
132 lscp_get_midi_instrument_maps();
133 lscp_list_midi_instrument_maps();
134 lscp_get_midi_instrument_map_name();
135 lscp_set_midi_instrument_map_name();
136
137
138 0.4.2 2006-12-04 MIDI instrument mapping fixed, previously missing
139 the regular ON_DEMAND load mode.
140
141 Server error reporting is now effective; all server
142 numerical error and warning codes are added to 100,
143 thus giving a proper non-zero lscp_client_get_errno()
144 return value.
145
146 0.4.1 2006-11-28 Fixed the flush timeout operation to be issued only
147 once, avoiding recurrent client failure after receive
148 timeout.
149
150 Support for very long command result sets have been
151 introduced, with the downside of strictly obeying
152 the LSCP draft.
153
154 list_midi_instruments() is now being implemented.
155
156 LGPL text is now back in COPYING.
157
158 0.4.0 2006-11-27 As of the LSCP 1.2 working draft document, added
159 some missing client interface functions:
160 lscp_get_total_voice_count();
161 lscp_get_total_voice_count_max();
162 and for the new MIDI instrumenbt mapping features:
163 lscp_map_midi_instrument();
164 lscp_unmap_midi_instrument();
165 lscp_get_midi_instruments();
166 lscp_get_midi_instrument_info();
167 lscp_clear_midi_instruments();
168
169
170 0.3.4 2006-09-24 GPL address update.
171
172 0.3.3 2006-06-01 Fixed some compilation warnings due to suspicious type
173 casting and unsused header macros.
174
175 Changed deprecated copyright attribute to license
176 and added ldconfig to post-(un)install steps
177 to liblscp.spec (RPM).
178
179 0.3.2 2005-08-29 Fixed missing initialization bug on lscp_channel_info_t
180 new struct fields (mute/solo).
181
182 Include debian files into distribution.
183
184 Renamed configure.in to newer configure.ac.
185
186 0.3.1 2005-08-16 [bug #21] Fixed automake support for separate build
187 directory.
188
189 Added support to sampler channel MUTE/SOLO states:
190 lscp_set_channel_mute();
191 lscp_set_channel_solo();
192 with corresponding new lscp_channel_info_t fields.
193
194 0.3.0 2005-06-10 [bug #11] Timeout flush idiosyncrasy is now a feature;
195 this just tries to flush the receive buffer whenever
196 any previous transaction has failed due to a timeout.
197
198 Fixed an off-by-one timeout quirk, that has been a real
199 showstopper on Mac OS X at least, which is incidental
200 to qsampler's default timeout setting of 1000 msecs,
201 giving up systematically on select() due to "Invalid
202 argument" (EINVAL).
203
204
205 0.2.8 2005-05-22 More LSCP command syntax changes, particularly on the
206 event subscription ones: the LSCP_EVENT_CHANNELS event
207 definition were renamed to LSCP_EVENT_CHANNEL_COUNT,
208 as to be more meaningful. Added support for the newest
209 LSCP command: GET SERVER INFO; lscp_get_server_info().
210
211 0.2.8 2005-05-08 [bug #9] Fixed for a LSCP command syntax convention
212 consistency, regarding the enumeration of available
213 sampler engines, Audio and MIDI drivers; this has
214 affected the signature of the following functions:
215 lscp_get_available_engines();
216 lscp_get_available_audio_drivers();
217 lscp_get_available_midi_drivers();
218 which are now returning an integer count of engines
219 and drivers, respectively, while the following
220 functions are now being introduced:
221 lscp_list_available_engines();
222 lscp_list_available_audio_drivers();
223 lscp_list_available_midi_drivers();
224 taking on the previous functionality, returning
225 a comma separated list of names.
226
227 0.2.7 2005-03-10 Mini bitsy regression; a severe crash (segfault)
228 was fixed on the device configuration functions:
229 lscp_set_audio_device_param();
230 lscp_set_midi_device_param();
231 lscp_set_audio_channel_param();
232 lscp_set_midi_port_param();
233
234 0.2.6 2005-03-01 Fixed nasty off-by-one bug on internal helpers.
235
236 0.2.5 2005-02-14 Added support for the new INSTRUMENT_NAME field
237 of GET CHANNEL INFO command.
238
239 0.2.4 2004-10-11 Fixed lscp_set_channel_midi_channel() again, MIDI
240 channels should be given in the range 0-15, and omni
241 mode with the LSCP_MIDI_CHANNEL_ALL symbol (16).
242
243 Fixed lscp_get_channel_info() to parse MIDI omni
244 (ALL) channels mode.
245
246 0.2.3 2004-09-28 Fixed lscp_set_channel_midi_channel() where MIDI
247 channels should be given in the range 1-16, and
248 omni mode with the new LSCP_MIDI_CHANNEL_ALL
249 symbol (0).
250
251 Rearrangement on main command requester executive.
252
253 0.2.2 2004-07-29 In sync with LSCP document draf (v.12).
254
255 New functions added: lscp_client_get_events() and
256 lscp_reset_sampler().
257
258 Added support for generating Debian packages;
259 renamed pkg-config lib name 'liblscp' -> 'lscp' as
260 it's common practice to omit the 'lib' prefix.
261
262 0.2.1 2004-07-09 Potential cripling defects habve been fixed.
263
264 0.2.0 2004-07-06 New LSCP extension draft (v.11) initial support.
265 (still a work in progress...)
266
267
268 0.1.9 2004-05-18 More fixes for MSVC++ example build.
269
270 0.1.8 2004-05-17 Fix for MSVC++ example build; snprintf replaced by
271 buffer overflow friendlier sprintf.
272
273 0.1.7 2004-05-10 Missing version.h now included on install; WIN32 is
274 only now conditionally defined.
275
276 0.1.6 2004-05-04 WIN32 build support; LPGL disclaimer consistency;
277 versioning functions introduced.
278
279 0.1.5 2004-04-26 Server stuff moved into examples.
280
281 0.1.4 2004-04-24 Initial auto/libtool preparation.
