The extra variables are now replaced (in addition to `$server`, `$channel` and
`$nick`):
- `${irc_server.xxx}`: variable xxx in server
- `${irc_channel.xxx}`: variable xxx in channel
The bar item "buffer_nicklist_count" is now the number of displayed nicks
only (not groups).
New bar items:
- "buffer_nicklist_count_groups": number of groups displayed
- "buffer_nicklist_count_all": number of nicks and groups displayed
Default value is changed for the following options:
* relay.irc.backlog_max_minutes: from 1440 to 0 (unlimited)
* relay.irc.backlog_max_number: from 256 to 1024
This allows the input callback function for a buffer to receive multiple
lines at once, instead of the message being split on newline before
being sent to the callback. It adds a new flag, input_multiline, to
control this. This flag defaults to 0 which is the current behavior.
New comparison operators:
- "==*": is matching mask, case sensitive (wildcard "*" is allowed)
- "!!*": is NOT matching mask, case sensitive (wildcard "*" is allowed)
- "==-": is included, case sensitive
- "!!-": is NOT included, case sensitive
- "=-": is included, case insensitive
- "!-": is NOT included, case insensitive
