2005-06-24
* README:
* configure.ac:
* packaging/fedora/libotr.spec:
* src/version.h: Change version to 3.0.0 (but don't yet release)
* Protocol: Clarify that, if the user requests to see the secure
session id in the middle of the conversation, the value
displayed should be the one calculated at the time the private
connection was established (the last Key Exchange Message that
caused a rekeying), _not_ the DH secure id calculated from DH
keys in more recent Data Messages.
* libotr.m4: Have the version check require an exact match on
the major version, since, for example, source that expects
libotr 2.0.0 won't work with libotr 3.0.0.
* libotr.m4: Add #include <stdlib.h> to the version test so that
it compiles cleanly with -Wall -Werror.
* src/proto.c:
* src/dh.h:
* src/dh.c:
* src/context.h:
* src/context.c: Save the secure session id so that it can be
displayed to the user upon request, instead of only when the
private session is initially set up.
* src/privkey.c:
* src/context.h:
* src/context.c: Allow the app to set a "trust level" for
fingerprints. This is an arbitrary string, intended to indicate
whether (or possibly by what means) the user has verified that
this fingerprint is accurate.
* src/context.h:
* src/context.c: Allow the app to set an arbitrary binary
"preshared secret" for the ConnContext. This is currently
unused, but in the future it would allow for users to exchange a
secret _before_ they generate their fingerprints. [But the
protocol would have to be extended to support this.]
* src/message.h:
* src/message.c: Remove the "confirm_fingerprint" callback
which requires the user to acknowledge the new fingerprint
before it can be used. Replace it with a "new_fingerprint"
callback which merely informs the user that a new fingerprint
has been received.
2005-05-13
* libotr.m4: Fixed a bug which made configure fail to find the
libotr header files if they weren't in the standard place.
2005-05-09
* src/privkey.c (otrl_privkey_read_fingerprints): Allow fields,
particularly accountnames, to contain spaces. Closes #1198379.
2005-05-03
* README:
* configure.ac:
* packaging/fedora/libotr.spec:
* src/version.h: Change version to 2.0.2
* packaging/debian: Remove this directory, as Thibaut VARENE
<[email protected]> is now responsible for the debian packages.
2005-02-23
* src/privkey.c (otrl_privkey_hash_to_human): Avoid writing a
NUL one byte past the end of the buffer
2005-02-16
* README:
* configure.ac:
* packaging/debian/changelog:
* packaging/fedora/libotr.spec:
* src/version.h: Change version to 2.0.1
2005-02-15
* src/message.c (otrl_message_sending, otrl_message_receiving)
(otrl_message_disconnect):
* src/proto.c (otrl_proto_accept_key_exchange)
(otrl_proto_create_data, otrl_proto_accept_data): Don't send
encrypted messages to a buddy who has disconnected his private
connection with us.
* src/message.c (otrl_message_sending): Don't show the user the
"the last message was resent" notice if the message has never
actually been sent before.
2005-02-09
* src/proto.c (otrl_proto_create_data): Copy the msg before
using since, since it may be an alias for context->lastmessage,
which we're going to gcry_free().
2005-02-08
* README:
* configure.ac:
* packaging/debian/changelog:
* packaging/fedora/libotr.spec:
