+	(otrl_tlv_serialize): Add missing "const"s.  (Closes #1243963)
+
+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
+	<varenet@debian.org> 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:

+
+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:
