+- update to 6.18.1:
+  * This is a patchfix release mainly dealing with issues arisen in Linux
+    package management. This contains the same code as 6.18.0, except for:
+  * A long-standing big-endian test failure with score strings has been
+    fixed.
+  * The symbol spillage caused by a build misconfiguration has been
+    resolved.
+  * Plugin ABI compatibility with earlier versions (affecting the FLTK
+    plugin) has been restored
+  * Some left-over tracing in the mod function has been removed.
+- update to 6.18.0:
+  * Mainly a bug-fixing release.  Major new facility is MP3 (MPEG) audio
+  * files are supported both for input and output in platforms where this is
+  * supported by libsndfile.
+  * fix midi list printing to stdout part of the list.
+  * Fixed bug where fixed-point phase computation (in oscil family) was
+  * incorrect resulting in slight freq deviations in very low freq cases.
+  * Fixed bug where freeing instr 0 caused memory issues in new
+  * compilations. Instr 0 is not freed until reset now.
+  * Fixed a bug where opcode directory search was crashing Csound if HOME
+  * variable not set.
+  * Fixed pol2rect array size setting.
+  * OSCsend, OSCsend_lo and OSClisten can now work with OSC messages
+  * carrying no payload (as per spec and manual).
+  * bug in sum fixed
+  * elapsedcycles, elapsedtime, eventcycles, and eventtime introducd as
+  * fixed versions of timek, times, timeinstk and timeinsts but return
+  * the correct values instead of being one cycle late.  This prserves
+  * backward compatability
+  * Csound now supports MP3 files for input and output through libsndfile
