+* Major changes in Gnuk 1.2.7
+
+  Released 2017-11-26, by NIIBE Yutaka
+
+** reGNUal
+reGNUal enables CRC module by itself.
+
+** Flash update change
+CRC module is disabled when Gnuk stops.  It's reGNUal which needs to
+enable CRC module.
+
+** Support of USB suspend
+USB suspend and wakeup event are now handled.
+
+** KDF-DO support and KDF by host
+KDF-DO is now available.  Host can use this feature.
+
+** Upgrade of Chopstx
+We use Chopstx 1.6.
+
+
+* Major changes in Gnuk 1.2.6
+
+  Released 2017-10-11, by NIIBE Yutaka
+
+** Port to GNU/Linux emulation
+We can "run" Gnuk Token on GNU/Linux by emulation through USBIP.
+
+** Upgrade of Chopstx
+We use Chopstx 1.5.
+
+
+* Major changes in Gnuk 1.2.5
+
+  Released 2017-08-11, by NIIBE Yutaka
+
+** "factory-reset" fix
+Gnuk's behavior was implemented by referring the gpg implementation.
+It found that gpg implementation was not good from the viewpoint of
+the OpenPGP card specification.  GnuPG was fixed to match the OpenPGP
+card specification already.  Thus, Gnuk is now fixed.
+
+** Upgrade of Chopstx
+We use Chopstx 1.4.

 Release Notes
 =============

-This is the release of Gnuk, version 1.2.4, which has major
+This is the release of Gnuk, version 1.2.7, which has major
 incompatible changes to Gnuk 1.0.x.  Specifically, it now supports
 overriding key import, but importing keys (or generating keys) results
-password reset.  Please update your documentation for Gnuk Token, so
+password reset.  Also, you need to import private keys before changing
+your password.  Please update your documentation for Gnuk Token, so
 that the instruction of importing keys won't cause any confusion.

 It has supports of EdDSA, ECDSA (with NIST P256 and secp256k1), and
 ECDH (with X25519, NIST P256 and secp256k1), but this ECC feature is
-somehow experimental, and it requires modern GnuPG 2.1 with libgcrypt
+somehow experimental, and it requires modern GnuPG 2.2 with libgcrypt
 1.7.0 or later.

 It also supports RSA-4096, but users should know that it takes more
 than 8 seconds to sign/decrypt.  Key generation of RSA-4096 just fails,
 because the device doesn't have enough memory.

+In this release, experimental KDF-DO support is added.  To use the
+feature, you need to build/install experimental branch of GnuPG by
+yourself:
+
+    https://dev.gnupg.org/source/gnupg/history/gniibe%252Fscd-kdf-support/
+
+And manually prepare the KDF-DO on your token.

The linker script should therefore reserve 1024 bytes per key instead of 512. In practice it's not an issue at all as all supported MCU have a page size bigger than 1024 bytes and Gnuk use one page per key.	2017-10-19 14:31:12 +09:00
NIIBE Yutaka	8ff3865890	Update ChangeLog, README, AUTHORS, and THANKS.	2017-10-17 15:26:46 +09:00
Aurelien Jarno	43009f39e8	polarssl: use a bigger sliding window when possible	2017-10-17 15:01:17 +09:00
Aurelien Jarno	56fb5002bf	malloc: rename MEMORY_ into HEAP_ That way MEMORY_SIZE can be exported in a later patch.	2017-10-17 15:01:13 +09:00
Aurelien Jarno	3bb5097031	polarssl: add ARM DSP optimized mpi_montsqr	2017-10-17 15:01:09 +09:00
Aurelien Jarno	8319f4a14b	polarssl: replace BIGNUM_C_IMPLEMENTATION check Replace the BIGNUM_C_IMPLEMENTATION check by a check on POLARSSL_HAVE_ASM and __arm__. This way it's possible to use this code on non arm, but also to run the GNU/Linux emulation on an arm machine, which is useful for debugging and profiling.	2017-10-17 15:01:06 +09:00
Aurelien Jarno	f7cf0a3461	polarssl: add ARM DSP optimized MULADDC code The Cortex M4, M7 MCUs and the Cortex A CPUs support the ARM DSP instructions, and especially the umaal instruction which greatly speed up MULADDC code.	2017-10-17 15:01:03 +09:00
Aurelien Jarno	5ac52d3f2f	polarssl: rename MULADDC_HUIT into MULADDC_HUIT_DEAD As the comment above said, it's dead code. Renaming it make sure it's not used by mistake, for example when testing/debugging code.	2017-10-17 15:01:00 +09:00
Aurelien Jarno	209d459d09	polarssl: fix build without POLARSSL_HAVE_ASM This fixes building polarssl for architectures without assembly code or when POLARSSL_HAVE_ASM is not defined. This has been done in upstream commit a755ca1bbe, but somehow the generic version has been missed in gnuk's version.	2017-10-17 15:00:55 +09:00

Jeremy Drake	eea011fe70	Allow compile-time override of detected flash size. On the STM32F103C8, as used in the "blue pill" boards, it has been determined that, despite these only officially having 64KiB flash, it is possible to actually use 128KiB of flash. This commit allows for a preprocessor define STM32F103_OVERRIDE_FLASH_SIZE which, when set, is used as the size of flash in KiB instead of reading it from the FLASH_SIZE_REG.	2017-08-03 21:20:47 +09:00
