CSOUND VERSION 6.17 RELEASE NOTES
Mainly a bug-fixing release but also a major re-organisation of the
libraries to move all opcodes with dependencies into a separate plugins
repository. The only exception to this is the OSC opcodes (which
depend on liblo). This is in part a preparation for Csound7. This is
the last release using the current parser (v.2).

scanmap and scansmap are like the xscanmap/xscansmap opcodes but
work with the mainstream scan opcodes. -

xscan opcodes are deprecated as they add nothing to the scan opcodes.
