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.
- Add 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

Don't send invalid 333 (RPL_TOPICWHOTIME) to client if topic owner is unknown (#1889)
Fix build with SWIG 4.2.0
Fix handling of timezones when parsing server-time tags received from server (#1857) (#1773)
Don't crash when receiving SASL lines from server without having negotiated SASL via CAP
Use module names as the module ident, otherwise some clients were merging conversations with different modules together. (#1874)
Fix an ODR violation (#1835)
Fix build with LibreSSL (#1828)
Better hide password in PASS debug lines, sometimes it was not hidden

modpython: Rewrite how modpython loads modules from imp to importlib: this adds support for Python 3.12. Also now it's possible to structure the module as a python package (a subdirectory with __init__.py 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 __init__.py format and implement some of the files in C. (#1724)
log: Add account to joins for the log module. (#1870)
clientnotify: Add options to reduce amount of notifications depending on the IP and the client ID of the connecting client (#1843)
modpython: Implement Module.AddCommand() (#1832) (#1833)
webadmin: Fix order of breadcrumbs in network page
watch: Allow new entries to use spaces (#1822)
route_replies: add Solanum-specific 337 (RPL_WHOISTEXT) to possible replies of /whois (#1881)
route_replies: route replies to /topic
modperl: allow overriding timer label
autoop: in some cases settings were parsed incorrectly, resulting in failure to do the autoop
sasl: don't forward 908 (RPL_SASLMECHS) to clients (#1756)
controlpanel: fix in help output

Require C++17 compiler. That is, GCC 8+ or Clang 5+. (#1887)
Remove autoconf, leave 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. 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
Drop support for Python < 3.4
Drop support for SWIG < 4.0.1
The systemd unit now passes --datadir=/var/lib/znc
