126 The following list shows the planned work to be done until the next
127 release of LinuxSampler. There will be no new release before all of them
128 are completed.

143 <h2>Features</h2>
144 <p class="default">
145 The following list shows which features have already been implemented in
146 current CVS version of LinuxSampler and what is planned to be done in
147 (hopefully) near future. If you are missing something that is not already
148 listed below, you can write a proposol to the
149 <a href="http://lists.sourceforge.net/lists/listinfo/linuxsampler-devel">
150 developers mailing list
151 </a> or even better send us your patch if you have done something. Even
152 if features are listed to be planned below, it can be that it takes a
153 while until somebody finds the time to implement it. So if you have the
154 time and will to finish one of them, let us know!
