== New ==
== New ==
* Require C++17 compiler. That is, GCC 8+ or Clang 5+. {{GH|1887}}
* Support for [https://ircv3.net/specs/extensions/capability-negotiation capability negotiation] 302 and <code>cap-notify</code>. ZNC now has API <code>AddServerDependentCapability()</code>, using which modules can easily implement new capabilities: if server supports a cap, it will automatically be offered to clients which support <code>cap-notify</code> and ZNC will notify the module when the capability is enabled or disabled for server and for each client. {{GH|1859}}
* Remove autoconf, leave only CMake as the build system. The <code>configure</code> script is now merely a wrapper for CMake, and accepts mostly the same parameters as the old <code>configure</code>. Minimum supported CMake version is 3.13.
** Several capabilities ([https://ircv3.net/specs/extensions/away-notify away-notify], [https://ircv3.net/specs/extensions/account-notify account-notify], [https://ircv3.net/specs/extensions/extended-join extended-join]) were moved from the core to a new module: corecaps.
* Update password hashing algorithm from SHA-256 to Argon2id (if libargon2 is installed). Existing passwords are transparently upgraded upon login. {{GH|1879}}
** The [[corecaps]] module is loaded automatically when upgrading from old config and when creating new config, but it's possible to unload it.
* Support for capability negotiation 3.2 and <code>cap-notify</code>. 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 <code>cap-notify</code> and ZNC will notify the module when the capability is enabled or disabled for server and for each client. {{GH|1859}}
*** '''NOTE''': Users who were using '''pre-release version of 1.9.x''' (from git or from nightly tarballs) will NOT have this module loaded automatically, because the existing config states <code>Version = 1.9</code>. This is to honor choice of users who decide to unload it, since we don't know whether the module is missing intentionally. You MUST manually load this module if you have clients or scripts that depends on away-notify, account-notify, account-tag, and/or extended-join.
* Add support for cap account-tag {{GH|1746}}
** Added support for [https://ircv3.net/specs/extensions/account-tag account-tag] capability, also in corecaps module {{GH|1746}}
* Updated password hashing algorithm from SHA-256 to [[wikipedia:Argon2|Argon2id]] (if libargon2 is installed). Existing passwords are transparently upgraded upon login. {{GH|1879}}
* Allow ordering of channels: via ListChans, MoveChan and SwapChans commands, and via webadmin {{GH|1744}}
* New user options: DenySetIdent, DenySetNetwork, DenySetRealName, DenySetQuitMsg, DenySetCTCPReplies {{GH|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 ==
== Fixes ==
* Don't send invalid 333 (RPL_TOPICWHOTIME) to client if topic owner is unknown {{GH|1889}}
* Fixed crash when receiving SASL lines from server without having negotiated SASL via CAP
* Fix build with SWIG 4.2.0, drop support for SWIG < 4.0.1
* Fixed build with SWIG 4.2.0
* Fix handling of timezones when parsing server-time tags received from server {{GH|1857}} {{GH|1773}}
* Fixed build with LibreSSL {{GH|1828}}
* Fixed handling of timezones when parsing server-time tags received from server {{GH|1857}} {{GH|1773}}
* Use module names as the module ident, otherwise some clients were merging conversations with different modules together. {{GH|1874}}
* Stopped sending invalid 333 (RPL_TOPICWHOTIME) to client if topic owner is unknown {{GH|1889}}
* Fixed an ODR violation {{GH|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 {{GH|1820}}


== Modules ==
== Modules ==
* modpython: Rewrite how modpython loads modules from <code>imp</code> to <code>importlib</code>: this adds support for Python 3.12, but bumps the minimum supported python version to 3.4. Also now it's possible to structure the module as a python package (a subdirectory with <code>__init__.py</code> and other .py files), however it no longer supports loading a C python extension through modpython - just write the module on C++ in such case instead of python, or use the <code>__init__.py</code> format and implement some of the files in C. {{GH|1724}}
* [[autoop]]: In some cases settings were parsed incorrectly, resulting in failure to do the autoop, now it's fixed
* log: Add account to joins for the log module. {{GH|1870}}
* [[clientnotify]]: Added options to reduce amount of notifications depending on the IP and the client ID of the connecting client {{GH|1843}}
* clientnotify: Add options to reduce amount of notifications depending on the IP and the client ID of the connecting client {{GH|1843}}
* [[controlpanel]]: Fixed help output
* modpython: Implement Module.AddCommand() {{GH|1832}}
* [[log]]: Log nickserv account in the joins lines. {{GH|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. {{GH|1724}}
*** Main motivation for the switch from using <code>imp</code> to using <code>importlib</code> 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 <code>__init__.py</code> 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 <code>__init__.py</code>.
** Implemented Module.AddCommand() {{GH|1832}} {{GH|1833}}
* [[route_replies]]:
** Added Solanum-specific 337 (RPL_WHOISTEXT) to possible replies of /whois {{GH|1881}}
** Route replies to /topic
* [[sasl]]: Don't forward 908 (RPL_SASLMECHS) to clients {{GH|1756}}
* [[webadmin]]: Fixed order of breadcrumbs in network page
* [[watch]]: Allow new entries to use spaces {{GH|1822}}

← 1.8.2 ZNC 1.9.0 git →
This is the latest release. Source tarball is available here.


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 version of 1.9.x (from git or from nightly tarballs) will NOT have this module loaded automatically, because the existing config states Version = 1.9. This is to honor choice of users who decide to unload it, since we don't know whether the module is missing intentionally. You MUST manually load this module if you have clients or scripts that depends on away-notify, account-notify, account-tag, and/or extended-join.
    • 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
