+	* Bumped version to 3.0.0.
+	* qrencode.[ch]:
+	  - QRcode_encodeInput() has changed the API. Previously it takes a
+	    QRinput, version and level, but now it takes only a QRinput, because
+		QRinput holds the version and level in it. From 3.0.0, you should set
+		them by calling QRinput_setVersion() and
+		QRinput_setErrorCorrectionLevel(), or use QRinput_new2() to
+		instantiate a QRinput object.

 ======================================
 
+Version 3.0.0 (2008.4.x)
+------------------------
+Summary:
+* A significant API change that requires to modify user applications.
+* Structured append support has been added. (patches from Yusuke Mihara)
+* "-S" option for structured append has been added to qrencode and view_qrcode.
+
+Release Note:
+
+Now libqrencode supports "structured-append" of symbols. A large data set can
+be split into multiple QR code symbols. The basic usage of structured-append
+is not so different from the single symbol encoding: just call
+QRcode_encodeStringStructured() or QRcode_encodeString8bitStructured() and
+they return a list of symbols. Instead of giving a string, you can encode
+an explicitly typed data. See the manual generated by Doxygen for the detailed
+usage.
+
+Many thanks to Yusuke Mihara, who contributed a patch to add support of
+structured-append to version 1.0.2.

+* Incompatible API changes:
+  - QRencode_encodeInput
+* New types:

+- Optimized encoding of a string

 - Micro QR Code
-- QR Code model 1
+- QR Code model 1 (deprecated)

 all of qrencode functions are thread unsafe because of them.
