ChangeLog/1.9.0

ZNC 1.9.0

New

Support for capability negotiation 3.2 and cap-notify. ZNC now has API, 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 using 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 won't have it loaded automatically. 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

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

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)

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

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
