ChangeLog/1.9.0

← 1.8.2

ZNC 1.9.0

1.9.1 →

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. (#1859)
  • 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 (#1746)
• Updated password hashing algorithm from SHA-256 to Argon2id (if libargon2 is installed). Existing passwords are transparently upgraded upon login. (#1879)
• Allow ordering of channels: via ListChans, MoveChan and SwapChans commands, and via webadmin (#1744)
• New user options: DenySetIdent, DenySetNetwork, DenySetRealName, DenySetQuitMsg, DenySetCTCPReplies (#1814)
• Switch --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 (#1828)
• Fixed handling of timezones when parsing server-time tags received from server (#1857) (#1773)
• Use module names as the module ident, otherwise some clients were merging conversations with different modules together. (#1874)
• Stopped sending invalid 333 (RPL_TOPICWHOTIME) to client if topic owner is unknown (#1889)
• Fixed an ODR violation (#1835)
• 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 (#1820)

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 (#1843)
• controlpanel: Fixed help output
• log: Log nickserv account in the joins lines. (#1870)
• 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. (#1724)
    • 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() (#1832) (#1833)
• route_replies:
  • Added Solanum-specific 337 (RPL_WHOISTEXT) to possible replies of /whois (#1881)
  • Route replies to /topic
• sasl: Don't forward 908 (RPL_SASLMECHS) to clients (#1756)
• webadmin: Fixed order of breadcrumbs in network page
• watch: Allow new entries to use spaces (#1822)

Notes for package maintainers

• Require C++17 compiler. That is, GCC 8+ or Clang 5+. (#1887)
• 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 (#1845)
• Added CodeQL (#1846)
• 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 (#1785)
• Web: removed legacy xhtml syntax (#1723)
• Documented more functions
• Made some integration tests run faster by changing ServerThrottle value in the test
