 libqrencode NEWS - Overview of changes
 ======================================
 
+Version 3.4.4 (2014.7.24)
+-------------------------
+* Bug fix release. (Thanks to Yoshimichi Inoue)
+* New option "--verbose" has been added to the command line tool.
+
+Release Note:
+When only one symbol is generated in structured-append mode, the library had
+inserted unnecessary chunk to the symbol and some QR Code readers fail to read
+it. Now the library omits the chunk and generate a symbol identical to non-
+structured symbol.
+
+
 Version 3.4.3 (2013.8.12)
-------------------------
+-------------------------
 * New option "--rle" has been added to the command line tool (Thanks to Daniel
   Dörrhöfer)
 * Bug fixes. (Thanks to Hassan Hajji, Emmanuel Blot, and ßlúèÇhîp)
