# ZNC 1.9.0 (2024-02-22)

## New
* Support for capability negotiation 302 and `cap-notify`. ZNC now has API `AddServerDependentCapability()`, using which modules can easily implement new capabilities: if server supports a cap, it will automatically be offered to clients which support `cap-notify` and ZNC will notify the module when the capability is enabled or disabled for server and for each client.
    * Several capabilities (`away-notify`, `account-notify`, `extended-join`) were moved from the core to a new module: corecaps.
    * The corecaps module is loaded automatically when upgrading from old config and when creating new config, but it's possible to unload it.
        * Note: users who were using pre-release versions of 1.9.x (from git or from nightly tarballs) won't have it loaded automatically, because the existing config states `Version = 1.9`. In such case you can load it manually. This is to honor choice of users who decide to unload it, since we don't know whether the module is missing intentionally.
    * Added support for `account-tag` capability, also in corecaps module.
* Updated password hashing algorithm from SHA-256 to Argon2id (if libargon2 is installed). Existing passwords are transparently upgraded upon login.
* Allow ordering of channels: via `ListChans`, `MoveChan` and `SwapChans` commands, and via webadmin.
* New user options: `DenySetIdent`, `DenySetNetwork`, `DenySetRealName`, `DenySetQuitMsg`, `DenySetCTCPReplies`.
* Switched `--makeconf` wizard default network from freenode to Libera.
* Added Portuguese and Turkish translations.
* znc-buildmod: output where the module was written to

## Fixes
* Fixed crash when receiving SASL lines from server without having negotiated SASL via CAP.
* Fixed build with SWIG 4.2.0.
* Fixed build with LibreSSL.
* Fixed handling of timezones when parsing server-time tags received from server.
* Use module names as the module ident, otherwise some clients were merging conversations with different modules together.
* Stopped sending invalid 333 (`RPL_TOPICWHOTIME`) to client if topic owner is unknown.
* Fixed an ODR violation.
* Better hide password in PASS debug lines, sometimes it was not hidden.
* CAP REQ sent by client without CAP LS now suspends the registration as the spec requires.

## Modules
* autoop: In some cases settings were parsed incorrectly, resulting in failure to do the autoop, now it's fixed.
* clientnotify: Added options to reduce amount of notifications depending on the IP and the client ID of the connecting client.
* controlpanel: Fixed help output.
* log: Log nickserv account in the joins lines.
* modperl: Allow overriding label for timers, which means now there can be more than 1 timer per module.
* modpython:
    * Rewrote internals of how modpython loads modules.
    * Main motivation for the switch from using `imp` to using `importlib` was to support Python 3.12+.
        * As an additional benefit, now it's possible to structure the module as a python package (a subdirectory with `__init__.py` and other .py files).
        * All the old python modules should load as they were before.
        * ZNC no longer supports loading a C python extension directly through modpython (though I doubt there were any users of that obscure feature): if you want to some parts of the module to be compiled, you can always import that from `__init__.py`.
    * Implemented `Module.AddCommand()`
* route_replies:
    * Added Solanum-specific 337 (`RPL_WHOISTEXT`) to possible replies of `/whois`.
    * Route replies to `/topic`.
* sasl: Don't forward 908 (`RPL_SASLMECHS`) to clients.
* webadmin: Fixed order of breadcrumbs in network page.
* watch: Allow new entries to use spaces.

## Notes for package maintainers
* Require C++17 compiler. That is, GCC 8+ or Clang 5+.
* Removed autoconf, leaving only CMake as the build system. The `configure` script is now merely a wrapper for CMake, and accepts mostly the same parameters as the old `configure`. You can use either `configure` as before, or CMake directly. Minimum supported CMake version is 3.13.
* If cctz library is available on the system, it will be used, otherwise the bundled copy will be used.
* libargon2 is new optional dependency.
* Dropped support for Python < 3.4
* Dropped support for SWIG < 4.0.1
* The systemd unit now passes `--datadir=/var/lib/znc`.

## Internal
* Switched to steady clock for cache map and for sockets to fix certain issues with leap seconds and DST.
* Made `CUser::Put...()` send to all clients instead of only networkless clients. Deprecate `CUser::PutAllUser()`.
* Setup Github Actions to replace old Travis CI setup.
* Added CIFuzz.
* Added CodeQL.
* List of translators is now automatically generated from Crowdin.
* Modernized the way how CMake is used.
* Updated default SSL settings from Mozilla recommendations.
* Rewrote message parsing using `std::string_view`, improving the performance of the parser.
* Web: removed legacy xhtml syntax.
* Documented more functions.
* Made some integration tests run faster by changing ServerThrottle value in the test.

# ZNC 1.6.6 (2018-03-05)

* Fix use-after-free in `znc --makepem`. It was broken for a long time, but
  started segfaulting only now. This is a useability fix, not a security fix,
  because self-signed (or signed by a CA) certificates can be created
  without using `--makepem`, and then combined into znc.pem.
* Fix build on Cygwin.



# ZNC 1.6.5 (2017-03-12)

## Fixes

* Fixed a regression of 1.6.4 which caused a crash in modperl/modpython.

  but without the `/` in the end.
* `znc-buildmod` now exits with non-zero exit code when the .cpp file is not found.
* Fixed `znc-buildmod` on Cygwin.
* ExpandString got expanded. It now expands `%znc%` to
  `ZNC <version> - http://znc.in`, honoring the global "Hide version" setting.
* Default quit message is switched from `ZNC <version> - http://znc.in` to `%znc%`,
  which is the same, but "automatically" changes the shown version when ZNC gets upgraded.
  Before, the old version was recorded in the user's quit message, and stayed the same
  regardless of the current version of ZNC.

## Modules
* modperl:
    * Fixed a memory leak.
* sasl:
    * Added an option to show which mechanisms failed or succeeded.
* webadmin:
    * Fixed an error message on invalid user settings to say what exactly was invalid.

      thought the user is going to change a password, but the passwords didn't match.



# ZNC 1.6.2 (2015-11-15)

## Fixes

* Fixed a use-after-delete in webadmin. It was already partially fixed in ZNC 1.4; since 1.4 it has been still possible to trigger, but much harder.

* Fixed a build failure when using an ancient OpenSSL version.
* Fixed a build failure when using OpenSSL which was built without SSLv3 support.

* autovoice:
    * Check for autovoices when we are opped.
* controlpanel:
    * Fixed `DelCTCPReply` case-insensitivity.

    * Add missing return statement. It was harmless.
* modpython:
    * Fixed a memory leak.
* modules_online:
    * Wrong ident was used before.
* stickychan:
    * Fixed to unstick inaccessible channels to avoid infinite join loops.

## Internal

* Fixed the nick passed to `CModule::OnChanMsg()` so it has channel permissions set.
* Fixed noisy `-Winconsistent-missing-override` compilation warnings.
* Initialized some fields in constructors of modules before `OnLoad()`.

## Cosmetic

* Various modules had commands with empty descriptions.
* perform:
    * Say "number" instead of "nr".

    * Improved the breadcrumbs.
    * Mentioned ExpandString in CTCP replies.
    * Added an explanation how to delete port which is used to access webadmin.

## Internal

* Fixed `CThreadPool` destructor to handle spurious wakeups.

# ZNC 1.6.0 (2015-02-12)

## New

* Switch versioning scheme to <major>.<minor>.<patch>.
* Add settings for which SSL/TLS protocols to use (SSLProtocols), which ciphers to enable (SSLCiphers). By default TLSv1+ are enabled, SSLv2/3 are disabled. Default ciphers are what Mozilla advices: https://wiki.mozilla.org/Security/Server_Side_TLS#Intermediate_compatibility_.28default.29

# ZNC 1.0 (2012-11-07)

## 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.

## Timezones
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.

## Fixes
* 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 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

* Modified description field for bouncedcc module to explain what the module actually does.
* nickserv: add support for nickserv requests on wenet.ru 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.

# ZNC 0.092 (2010-07-03)

## Fixes

* The traffic stats caused a NULL pointer dereference if there were any unauthenticated connections. CVE-2010-2488 (r2051)
* Csocket had a bug where a wrong error message was generated and one that caused busy loops with c-ares. (r2053)

# ZNC 0.090 (2010-06-06)

## Upgrading from previous versions

## Errors during start-up
The shell, email and imapauth modules have been moved from the regular module set to the "extra" set, you have to use --enable-extra with ./configure to compile them.

So, to fix these errors, edit the znc.conf file in ~/.znc/configs and don't load those modules, or recompile znc with extra.

### WebMods
While previously only the "webadmin" provided an HTTP server/interface, the HTTP server is now integrated into ZNC's core. This means that all modules (not only webadmin) can now provide web pages. Examples shipping with ZNC are lastseen, stickychan and notes. Old-style module arguments to webadmin will be automatically converted to the new syntax.

Please note that the WebMods interface uses session cookies instead of 'Basic' HTTP authentication.

All URLs to webadmin's settings pages have changed. Please adjust your scripts etc. if necessary.

### Running without installing
If you want to run ZNC without doing make install, i.e. if you want to run it from the source dir, you will have to add --enable-run-from-source as an argument to ./configure. You do not have to care about this if you use a --prefix= or if you install ZNC system-wide.

### I upgraded and WebAdmin/WebMods is acting weird, Log Out does not work.
Starting with 0.090, ZNC uses cookies instead of HTTP Basic authentication. If your browser is still sending the Basic credentials to ZNC, e.g. because you have saved them in a bookmark, or password manager, or simply haven't restarted your browser in a while, those will continue to work, even after you click the Log Out button.

To fix this, remove any user:pass@host portions from your bookmarks, remove all entries for ZNC's web interface from your password manager, and restart your browser.

# ZNC 0.066 (2009-02-24)

There was a privilege escalation bug in webadmin which could allow all ZNC users to write to znc.conf. They could gain shell access through this. (r1395) (r1396)

This is CVE-2009-0759.

## Affected versions
This bug affects all versions of ZNC which include the webadmin module. Let's just say this affects every ZNC version, ok? ;)

## Who can use this bug?
First, ZNC must have the webadmin module loaded and accessible to the outside. Now any user who already has a valid login can exploit this bug.

An admin must help (unknowingly) to trigger this bug by reloading the config.

## Impact
Through this bug users can write arbitrary strings to the znc.conf file.

Unprivileged ZNC users can make themselves admin and load the shell module to gain shell access.
Unprivileged ZNC users can temporarily overwrite any file ZNC has write access to via ISpoof. This can be used to overwrite ~/.ssh/authorized_keys and gain shell access.
Unprivileged ZNC users can permanently truncate any file to which ZNC has write access via ISpoof. ZNC never saves more than 1kB for restoring the ISpoofFile.

## How can I protect myself?
Upgrade to ZNC 0.066 or newer or unload webadmin.

## What happens?
Webadmin doesn't properly validate user input. If you send a manipulated POST request to webadmin's edit user page which includes newlines in e.g. the QuitMessage field, this field will be written unmodified to the config. This way you can add new lines to znc.conf. The new lines will not be parsed until the next rehash or restart.

This can be done with nearly all input fields in webadmin. Because every user can modify himself via webadmin, every user can exploit this bug.

## Thanks
Thanks to cnu for finding and reporting this bug.

* Added the admin module. (r1379) (r1386)
* savebuff and away no longer ask for a password on startup. (r1388)
* Added the fail2ban module. (r1390)

## Fixes
