Noteworthy changes in version 1.9.0 (unreleased)
------------------------------------------------
* gpg does now also use libgcrypt, libgpg-error is required.
* New gpgsm commands --call-dirmngr and --call-protect-tool.
* Changing a passphrase is now possible using "gpgsm --passwd"

@ -1,3 +1,25 @@
2003-06-27 Werner Koch <wk@gnupg.org>
* seckey-cert.c (check_secret_key): Bypass the unprotection for
mode 1002.
* sign.c (do_sign): Handle card case (i.e. mode 1002).
2003-06-26 Werner Koch <wk@gnupg.org>
* build-packet.c (do_secret_key): Implement special protection
mode 1002.
* parse-packet.c (parse_key): Likewise.
* keygen.c (smartcard_gen_key): New.
* call-agent.c (agent_scd_setattr): New.
2003-06-24 Werner Koch <wk@gnupg.org>
* Makefile.am: Removed signal.c
* g10.c (emergency_cleanup): New.
(main): Use gnupg_init_signals and register malloc for assuan.
2003-06-23 Werner Koch <wk@gnupg.org>
* keyid.c (do_fingerprint_md): Made it work again.
