+Version 1.36
+------------
+Add mount option for disabling the default behavior of sending byte range lock
+requests to the server (necessary for certain applications which break with
+mandatory lock behavior such as Evolution), and also mount option for
+requesting case insensitive matching for path based requests (requesting
+case sensitive is the default).
+
Version 1.35
------------
Add writepage performance improvements. Fix path name conversions

This has no effect if the server does not support
Unicode on the wire.
nomapchars Do not translate any of these seven characters (default).
+ nocase Request case insensitive path name matching (case
+ sensitive is the default if the server suports it).
+ nobrl Do not send byte range lock requests to the server.
+ This is necessary for certain applications that break

or vice versa)
