# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3      * SFZ format engine:
4        - added support for <global>, <master> and #define (patch by Alby M)
5    
6      * general changes:
7        - fixed printf type errors (mostly in debug messages)
8        - use unique_ptr instead of auto_ptr when building with C++11
9        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
10          allowing to sort data efficiently in real-time safe manner.
11        - RTList class: added methods for moving/inserting elements to arbitrary
12          position within a list.
13        - RTList class: added method fromPtr() for creating an Iterator object from
14          a raw element pointer.
15        - Attempt to partly fix resetting engine channels vs. resetting engine, an
16          overall cleanup of the Reset*(), ConnectAudioDevice(),
17          DisconnectAudioDevice() API methods would still be desirable though,
18          because the current situation is still inconsistent and error prone.
19        - Active voices are now internally grouped to "Note" objects, instead of
20          being directly assigned to a keyboard key. This allows more fine graded
21          processing of voices, which is i.e. required for certain instrument
22          script features.
23    
24      * packaging changes:
25        - removed unnecessary dependency to libuuid
26          (originated by libgig's usage of it)
27        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
28          auto detect whether it (sh/c)ould output its messages in color.
29    
30      * Real-time instrument scripts:
31        - Implemented scheduler for delayed MIDI events and for suspended scripts.
32        - Built-in script function "wait()": implemented support for function's
33          "duration-us" argument, thus scripts using this function are now
34          correctly resumed after the requested amount of microseconds.
35        - Built-in script function "play_note()": implemented support for
36          function's "duration-us" argument, thus notes triggered with this
37          argument are now correctly released after the requested amount of
38          microseconds.
39        - Fix: script events were not cleared when engine channel was reset,
40          potentially causing undefined behavior.
41        - Fixed crash which happened when trying to reference an undeclared
42          variable.
43        - Built-in script function "play_note()": Added support for passing
44          special value -1 for "duration-us" argument, which will cause the
45          triggered note to be released once the original note was released.
46        - Instrument script classes now exported with the liblinuxsampler C++ API.
47        - Added new API method ScriptVM::syntaxHighlighting() which provides
48          a convenient syntax highlighting backend for external instrument
49          script editor applications.
50        - Added new C++ API class "ScriptVMFactory".
51        - Extended parser issues to provide not only first line and first
52          column, but also last line and last column of issue (thus marking
53          the precise span of the issue within the source code).
54    
55    Version 2.0.0 (15 July 2015)

82        - build fix: ChangeFlagRelaxed.h was missing in makefile
83        - build fix: libsndfile compiler flags were missing in some
84          makefiles
85        - fix for building with bison 3.0 (#202)
86        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
87          on the process's main thread
88        - fixed build error on newer MinGW
89        - support building with older jack versions
90        - support building with spaces in vst sdk path
91        - enabled automake 'subdir-objects' option and moved external
92          source references (vst, au, asio) from makefiles to cpp files,
93          in order to get rid of warnings from automake 1.14

133        series (#182)        series (#182)
134        - added a lock guard class for exception safe mutex handling and
135          used it everywhere appropriate
136        - Immediately apply scale tuning changes to active voices.
137        - Exposed scale tuning to C++ API (along to the already existing standard
138          SysEx way).
139        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
140          and broken for ppc64. (Seq_cst loads and stores are actually not
141          used in LS, so the bug wasn't noticable.)
142        - lsatomic.h: added ARMv7 support
143        - Added support for multiple MIDI input ports per sampler channel (and
144          added various new C++ methods for this new feature / design change, old
145          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
146          as deprecated but are still there and should provide full behavior
147          backward compatibility).
148        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
149          unsafe and caused compilation error with clang 2.x).
150        - Bugfix: only process the latest MIDI program change event.
151        - Introducing the LSCP shell, which provides convenient control of the
152          sampler from the command line by providing LSCP aware features.
153        - VirtualMidiDevice: Added support for program change.
154        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
155        - VirtualMidiDevice: Added support for pitch bend.
156        - Aftertouch: extended API to explicitly handle channel pressure and
157          polyphonic key pressure events (so far polyphonic pressure was not
158          supported at all, and channel pressure was rerouted as CC128 but not
159          used so far).
160        - Added initial support for real-time instrument scripts. The script VM
161          code is shared by all sampler engine implemementations, however only the
162          gig file format currently provides support for storing instrument scripts
163          (as LinuxSampler extension to the original GigaStudio 4 format).

396      * Instrument editor interface:
397        - Changed instrument editor plugin interface, providing additional
398          informations like the EngineChannel for which the instrument editor was
399          spawned for. This allows the instrument editors to interact more actively
400          with the sampler.

476        - provide comprehensive error messages on LSCP syntax errors
477          (suggesting expected next non-terminal symbols)
478    
479      * LSCP shell:
480        - Added support for auto correction of obvious and trivial syntax mistakes.
481        - Added support for auto completion by tab key.
482        - Show currently available auto completion while typing.
483        - Added support for browsing command history with up / down keys.
484        - Show all possible next symbols immediately right to the current command

488        - Added support for built-in LSCP reference documentation, which will

538          (i.e. return value of new script function "by_marks()").
539        - Pass/preserve polyphonic variable data from respective "note" event
540          handler to "release" event handler.

586        - ignore missing LADSPA paths without ignoring valid LADSPA paths
587          (fixes #208)
588        - Fixed bug in LSCP grammar definition which caused a statement like
589          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
590          practically irrelevant, however it caused problems with the new LSCP
591          shell's auto completion feature).
592        - Fixed MIDI program change messages being ignored if quickly executed
