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
znc-buildmod: output where the module was written to
Add Portuguese and Turkish translations

Fixed build with SWIG 4.2.0
Fixed build with LibreSSL (#1828)
Fixed crash when receiving SASL lines from server without having negotiated SASL via CAP
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

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)
Removed 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
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 recommmendations
Rewrote message parsing using std::string_view, improving the performance of the parser (#1785)
Web: remove legacy xhtml syntax (#1723)
Documented more functions
Made some integration tests run faster by changing ServerThrottle value in the test
