 Gnuk NEWS - User visible changes

+* Major changes in Gnuk 0.17
+
+  Released 2012-01-XX, by NIIBE Yutaka
+
+** USB CCID/ICCD low level bug is fixed
+When the size of command APDU data is just 49, the lower level packet
+size is 64.  This is maximum size of BULK-OUT transfer packet, and
+caused trouble in the past implementations.  Example is setting url
+(0x5f50) as: http://www.gniibe.org/adpu-string-size-is-just-49
+This is because the past implementations expect ZLP (zero size
+packet).  Now, it has been fixed.  You can use any size.
+
+** CERT.3 Data Object (0x7f21) is now optional
+As there's no valid use case for this data object and it does not
+work as current version of GnuPG, this is now optional feature.
+You can enable this data object by specifying --enable-certdo at
+configure time.
+
+** With DnD pinentry, user can cancel pin input
+Now, user can cancel pin input by unmounting device before finishing
+DnD.
+
+** New tool: pinpad-test.py
+The tool pinpad-test.py is PC/SC test tool for pinentry of pinpad with
+OpenPGP card v2.
+
+
+* Major changes in Gnuk 0.16
+
+  Released 2011-12-14, by NIIBE Yutaka
+
+** DnD pinentry support is added and it's default to pinentry support
+DnD pinentry support doesn't require any hardware extension, but
+emulates mass storage class device of USB.  User inputs pass phrase
+by "drag and drop"-ing folders using file manager or something.
+
+** Bug fix for VERIFY for CHV2
+With no keys, VERIFY command for CHV2 used to fail even if pass phrase
+is correct.  It was intentional, because CHV2 verification would be
+useless with no keys.  But there is a corner case for PRIVATE-DOs,
+which may requires CHV2 verification.  Even though Gnuk doesn't
+support any PRIVATE-DOs, it is good to be fixed.
+
+** Changed bcdUSB = 1.1
+Gnuk device conforms to USB 2.0 full speed device, but when it was
+2.0, some OS informs users, "you can connect the device to 2.0
+compliant hub so that it can have better bandwidth", which is not
