 Gnuk NEWS - User visible changes
 
 
+* Major changes in Gnuk 1.2.19
+
+  Released 2021-10-12, by NIIBE Yutaka
+
+** KDF Data Object configuration
+KDF Data Object should be highly recommended for all configurations.
+Nevertheless, for backward compatibillity, in Gnuk 1.2, it is optional
+by default; It is up to user to configure KDF Data Object before
+importing private keys.  In this situation, it is not good to
+introduce new build-time option like --enable-always-require-kdf-do,
+because it might wrongly encourage use of Gnuk with no KDF Data Object
+setting, by confusion.  If needed, please run configure:
+
+  kdf_do=required ./configure --enable-factory-reset --target...
+
+or
+
+  kdf_do=optional ./configure --enable-factory-reset --target...
+
+Please note that such a use of variable by shell command line is not
+well supported by the configure script (for other variables), but
+override of kdf_do is needed in some situations.
+
+** Upgrade of Chopstx
+We use Chopstx 1.20.  This enables use with PC/SC for GNU/Linux
+emulation.
+
+
+* Major changes in Gnuk 1.2.18
+
+  Released 2021-04-02, by NIIBE Yutaka
+
+** GNU/Linux emulation bug fix
+This time, for GNU/Linux emulation, KDF Data Object is required before
+keygen and key import, really.
+
+** tool/upgrade_by_passwd.py
+Now, it checks if the target of binary being written and the
+configured target of running device are same.  This check can be
+skipped by -s option.  Please note that FST-01 and FST-01SZ are
+different target, as it's MHz is different.
+
+
+* Major changes in Gnuk 1.2.17
+
+  Released 2021-02-25, by NIIBE Yutaka
+
+** GNU/Linux: KDF Data Object is required before keygen and key import
+For GNU/Linux emulation, KDF Data Object is required before keygen and
+key import.
+
+** GNU/Linux emulation
+Since 1.2.10, it was not build-able because of MHZ definition.  It is
+build-able again, and its USB product string is now "Gnuk Token".  It
+has ACK button support using terminal.  It now has start-up message,
+and its driver show useful information to setup USBIP.  When no file
+for the .gnuk-flash-image file, it is automatically created.
+
+** Removal of tool/gnuk-emulation-setup
+Because it is automatically created, the tool is not needed any more.
+
+** Upgrade of Chopstx
+We use Chopstx 1.19.
