+
+ * Implemented the BAN command to the client library.
+
+ * The JOIN command in the server now checks the invite list
+ and the ban list.
+
+ * Changed the silc_command_reply_payload_encode_va and the
+ silc_command_payload_encode_va to support that if argument is
+ NULL it ignores and checks the next argument. Affected file
+ lib/silccore/silccommand.c.
+
+ * Added silc_server_send_notify_ban to send the BAN notify
+ type between routers.
+
+ * Chaned the silc_notify_payload_encode to support that if
+ argument is NULL it ignores and checks the next argument.
+ Affected file lib/silccore/silcnotify.c.
+
+ * Tested ban lists in router environment successfully.

+Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Implemented BAN command to the server, in silcd/command.[ch].
+
+ * Removed the BAN and INVITE_LIST modes from the CMODE command
+ in the server code.
+
+ * Added function silc_string_match to regex match two strings.
+ Affected files lib/silcutil/silcutil.[ch].
+
+Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Redefined parts of the SilcChannelEntry in the server to support
+ the new ban and invite lists.

Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Redefined the INVITE command. The same command can be used to
l <limit> Set/unset channel's user limit
a <passphrase> Set/unset passphrase for channel that must
be provided when joining to the channel.

Multiple modes can be set/unset at once if the modes does not

- Arguments: (1) [<Client ID>] (2) [<Channel ID>]
+ Arguments: (1) [<Client ID>] (2) <Channel ID>
(3) [<adding client>] (4) [<removing client>]
This command is used to invite other clients to join to the
nickname and hostname and add to the invite list before sending
the notify packet.
- When this command is given without any arguments then the command
- merely returns the invite list of the channel. This command must
- fail if the requested channel does not exist, the requested
- <Client ID> is already on the channel or if the channel is invite
- only channel and the caller of this command does not have at least
- channel operator privileges.
+ When this command is given with only <Channel ID> argument then

Reply messages to the command:
Arguments: (1) <Status Payload> (2) <channel>

This command is used to manage the ban list of the channel
from than one clients then the lists are an comma (`,') separated
list.
- If this command is executed without any arguments the command
+ If this command is executed without the ban arguments the command
merely replies with the current ban list.
