The Big News

Multiple networks per user

Think about new users as "user groups", while new networks are similar to old users.

To login to ZNC, use user/network:password as password, or user/network as username. Also, you can switch between different networks on the fly using the /znc JumpNetwork command.

When you first run ZNC 1.0, it will automatically convert your config and create a network called "default" for each user. Settings from each user are moved into these "default" networks. When you log into ZNC without setting a network, the "default" network will automatically be chosen for you.

Users can create new networks up to an admin-configurable limit. By default, this limit is one network per user.

Existing user-per-network setups can be migrated to the new multinetwork setup using the /znc MoveNetwork command.

You can see a list of networks via /znc ListNetworks and /znc ListAllUserNetworks.


Timezone can now be configured by name, e.g. "GMT-9", or "Europe/Madrid". Old TimezoneOffset setting (which was the number of hours between the server's timezone and the user's timezone) is deprecated and should not be used anymore. Its old value is lost. The reason for this change is that the old TimezoneOffset was not trivial to count and often broke during switches to/from daylight savings time.

So if you previously used the TimezoneOffset option, you now have to configure your timezone again (via the webadmin or controlpanel module).

No more ZNC-Extra

Most modules from ZNC-Extra are now enabled in the usual installation. It was pointless to have them shipped in the tarball, but requiring user to add some weird flags to ./configure.

Antiidle, fakeonline and motdfile modules are dropped.

Away module is renamed to awaystore to better explain its meaning.


  • Don't try IPv6 servers when IPv6 isn't available. Use threads for non-blocking DNS instead of c-ares.
  • Fix debug output of identfile.
  • Don't forward WHO replies with multi-prefix to clients which don't support multi-prefix
  • Send nick changes to clients before we call the OnNick module hook
  • Don't connect to SSLed IRC servers when ZNC is compiled without SSL support
  • Fix check for visibility support in the compiler
  • Fix compilation on cygwin again, including modperl and modpython
  • Support parting several channels at once
  • Fix a crash in admin (now controlpanel) module
  • Fix webadmin to deny setting a bindhost that is not on the global list of allowed bindhosts.
  • Fix using empty value for defaults in user page in webadmin.

Minor Stuff

  • Rename admin module to controlpanel to make it clearer that it's not the same as admin flag of a user.
  • Add protection from flood. If you send multiple lines at once, they will be slowed down, so that the server will not disconnect ZNC due to flood. It can be configured and can be completely turned off. Default settings are: 1 line per second, first 4 lines are sent at once.
  • Modules can support several types now: a module can be loaded as a user module, as a network module and as a global module, if the module supports these types.
  • Rename (non-)KeepBuffer to AutoClearChanBuffer
  • Process starttls numeric
  • Improvements to modperl, modpython, modtcl.
  • Add timestamps to znc --debug
  • Listeners editor in webadmin
  • Add sasl module which uses SASL to authenticate to NickServ.
  • Rename saslauth to cyrusauth, to make it clearer that it's not needed to do SASL authentication to NickServ.
  • Modules get a way to describe their arguments.
  • webadmin: allow editing of the bindhost without global list.
  • Don't send our password required notice until after CAP negotiation
  • Rewrite the JOIN channel logic, dropping MaxJoins
  • Support messages directed to specific user prefixes (like /msg @#channel Hello)
  • Show link to from web as a link. It was plain text before.
  • Webadmin: use HTML5 numeric inputs for numbers.
  • Add SSL/IPv6/DNS info to znc --version
  • Clarify that only admins can load the shell module.
  • cyrusauth: Allow creating new users on first login
  • Clear channel buffers when keep buffer is disabled if we're online

  • identfile: Pause the connection queue while we have a locked file
  • Add ShowBindHost command
  • autoop: Check for autoops when we get op status
  • Improvements and fixes to the partyline module
  • partyline Drop support for fixed channels
  • Check that there're modules available on startup. Check if ZNC is installed or not.
  • Modified description field for bouncedcc module to explain what the module actually does.
  • nickserv: add support for nickserv requests on and rusnet.
  • send 422 event if MOTD buffer is empty
  • route_replies: Handle much more replies
  • Clear text colors before appending timestamps to buffer lines, add space before AppendTimestamp for colorless lines.
  • Don't replace our motd with a different servers motd
  • webadmin: Add a "Disabled" checkbox for channels
