 Version 1.46
 ------------
 Support deep tree mounts.  Better support OS/2, Win9x (DOS) time stamps.
+Allow null user to be specified on mount ("username="). Do not return
+EINVAL on readdir when filldir fails due to overwritten blocksize
+(fixes FC problem).  Return error in rename 2nd attempt retry (ie report
+if rename by handle also fails, after rename by path fails, we were
+not reporting whether the retry worked or not).
 
 Version 1.45
