ChangeLog:
+nxcomp-3.2.0-6
+
+- Changes considering that unsetenv() returns void on Mac OS X.
+
+nxcomp-3.2.0-5
+
+- Fixed TR03F02024. Assume the launchd unix socket as X socket.
+
+- Changed the authorization cookie retrieval when using the launchd
+ socket on MacOSX, in order to wait for the X server start.
+
+nxcomp-3.2.0-4
+
+- Fixed TR03F02026. Unset environment variable LD_LIBRARY_PATH before
+ calling the exec function running nxclient.
+
+nxcomp-3.2.0-3
+
+- Fix addMsTimestamp() and subMsTimestamp(). Remove the check for
+ a valid input in diffTimestamp() and diffUsTimestamp().
+
+nxcomp-3.2.0-2
+
+- Fixed TR12E01973. Now the correct number of bits are used for the
+ number of points in a X_FillPoly request.
+
+nxcomp-3.2.0-1
+
+- Opened the 3.2.0 branch based on nxcomp-3.1.0-6.
