 * Support for reader initialisation was added to the PDF417 and MicroPDF417 encoders via a new readerinit option.
+* Support for FNC1 in second position was added to the Code 128, Code 16K, Code 49, PosiCode, Data Matrix, Aztec Code, Code One, DotCode, QR Code, Rectangular Micro QR Code and MicroPDF417 encoders, declared with ^FNC@ followed by an AIM application indicator of one letter or two digits.
+* The QR Code, Data Matrix, Aztec Code, DotCode and Code One encoders were changed to refuse ECIs with FNC1 in first position, which denotes GS1 AI syntax.
+* The QR Code encoder, including GS1 QR Code, was fixed in FNC1 mode so that a % encoded in byte mode is no longer doubled.
+* The QR Code encoder was fixed in FNC1 mode so that an FNC1 followed by % or another FNC1 is no longer misread.
+* The Code 49 encoder was fixed to encode a numeric run of one more than a multiple of five digits that follows other data, which raised an error.
