 Gnuk NEWS - User visible changes

+* Major changes in Gnuk 0.15
+
+  Released 2011-11-24, by NIIBE Yutaka
+
+** New targets: FST_01 and FST_01_00
+Flying Stone Technology's open hardware, Flying Stone Tiny 01 is
+supported.
+
+** Flash writing tool for "DfuSe" is improved
+Now, it support holes and unaligned blocks in hex file.
+
+** Experimental PIN-pad support (by TV controller) change
+Now, Gnuk has codetables for conversion from CIR code to ASCII code.
+Note that only four controllers (of Dell, Sharp, Sony, and Toshiba)
+are supported and tested.
+
+** It is possible for users to keep using OPENPGP_CARD_INITIAL_PW1
+With a bug fix of verify_user_0, it's now possible.  Although it's not
+recommended.
+
+** Important bug fix and a workaround
+In version 0.14, __main_stack_size__ (for interrupt handler) was too
+small for some cases.  This is fixed in 0.15.
+
+In src/Makefile.in, added -mfix-cortex-m3-ldrd for correctly linking C
+library for thumb2.  This is needed for newer summon-arm-toolchain.
+
+
+* Major changes in Gnuk 0.14
+
+  Released 2011-10-07, by NIIBE Yutaka
+
+** Random number generator change
+NeuG, Gniibe's True RNG implementation for STM32F103, has been
+integrated to Gnuk.  It is not needed to put random number bytes
+(generated by host) to Token any more.
