53        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
54          parameter) and crossfade
55        - added support for the "attenuation controller threshold" gig
56          parameter
57        - added smoothing of volume changes caused by control change
58          messages
59        - sample loop parameters are now taken from the DimensionRegion
60          instead of the wave chunk
61        - fixed keyswitching for v3 gigs with a number of keyswitch splits
62          not equal to a power of two
63        - reimplementation of the filter algorithm. The new filter is more
64          accurate and supports all gig filter types, including bandreject
65          and lowpass turbo.
66        - real support for 24 bit samples - samples are not truncated to
67          16 bits anymore
68        - support for aftertouch (channel pressure, not polyphonic
69          aftertouch)
70        - LFO1 behaviour fixed (dampening from max volume instead of
71          amplifying from 0)

86        - API extension for MIDI drivers which already supply exact time stamps
87          for events (i.e. for offline rendering based MIDI drivers)
88        - added checks for bad MIDI data
89    
90      * linuxsampler application:
91        - show available sampler engine types on startup

105        - fixed some memory management errors
106        - fixed some concurrency problems that could lead to crashes when
107          LSCP commands were executed
108        - fixed crash when instrument loading failed previously on the same
