* Add CMake build. Minimum supported CMake version is 3.1. For now ZNC can be built with either CMake or autoconf. In future autoconf is going to be removed.
* Currently `znc-buildmod` requires python if CMake was used; if that's a concern for you, please open a bug.
* Increase minimum GCC version from 4.7 to 4.8. Minimum Clang version stays at 3.2.
* Make ZNC UI translateable to different languages (only with CMake), add partial Russian and German translations.
* If you want to translate ZNC to your language, please join https://crowdin.com/project/znc-bouncer
* Configs written before ZNC 0.206 can't be read anymore
* Implement IRCv3.2 capabilities `away-notify`, `account-notify`, `extended-join`
* Implement IRCv3.2 capabilities `echo-message`, `cap-notify` on the "client side"
* Update capability names as they are named in IRCv3.2: `znc.in/server-time-iso`→`server-time`, `znc.in/batch`→`batch`. Old names will continue working for a while, then will be removed in some future version.
* Make ZNC request `server-time` from server when available
* Increase accepted line length from 1024 to 2048 to give some space to message tags
* Separate buffer size settings for channels and queries
* Support separate `SSLKeyFile` and `SSLDHParamFile` configuration in addition to existing `SSLCertFile`
* Add "AuthOnlyViaModule" global/user setting
* Added pyeval module
* Added stripcontrols module
* Add new substitutions to ExpandString: `%empty%` and `%network%`.
* Stop defaulting real name to "Got ZNC?"
* Make the user aware that debug mode is enabled.
* Added `ClearAllBuffers` command
* Don't require CSRF token for POSTs if the request uses HTTP Basic auth.
* Set `HttpOnly` and `SameSite=strict` for session cookies
* Add SNI SSL client support
* Add support for CIDR notation in allowed hosts list and in trusted proxy list
* Add network-specific config for cert validation in addition to user-supplied fingerprints: `TrustAllCerts`, defaults to false, and `TrustPKI`, defaults to true.
* Add `/attach` command for symmetry with `/detach`. Unlike `/join` it allows wildcards.
* Timestamp format now supports sub-second precision with `%f`. Used in awaystore, listsockets, log modules and buffer playback when client doesn't support server-time
* Build on macOS using ICU, Python, and OpenSSL from Homebrew, if available
* Remove `--with-openssl=/path` option from ./configure. SSL is still supported and is still configurable
Fixes
=====
* Revert tables to how they were in ZNC 1.4
* Remove flawed Add/Del/ListBindHost(s). They didn't correctly do what they were intended for, but users often confused them with the SetBindHost option. SetBindHost still works.
* Fix disconnection issues when being behind NAT by decreasing the interval how often PING is sent and making it configurable via a setting to change ping timeout time
* Change default flood rates to match RFC1459, prevent excess flood problems
* Match channel names and hostmasks case-insensitively in autoattach, autocycle, autoop, autovoice, log, watch modules
* Fix crash in shell module which happens if client disconnects at a wrong time
* Decrease CPU usage when joining channels during startup or reconnect, add config write delay setting
* Always send the users name in NOTICE when logging in.
* Don't try to quit multiple times
* Don't send PART to client which sent QUIT
* Send failed logins to NOTICE instead of PRIVMSG
* Stop creating files with odd permissions on Solaris
* Save channel key on JOIN even if user was not on the channel yet
* Stop buffering and echoing CTCP requests and responses to other clients with self-message, except for /me
* Support discovery of tcl 8.6 during `./configure`
