ZNC 1.6.0

Changes since ZNC 1.4

New
===

* Switch versioning scheme to <major>.<minor>.<patch>.
* Add settings for which SSL/TLS protocols to use (SSLProtocols), which ciphers to enable (SSLCiphers). By default TLSv1+ are enabled, SSLv2/3 are disabled. Default ciphers are what Mozilla advices: https://wiki.mozilla.org/Security/Server_Side_TLS#Intermediate_compatibility_.28default.29
* Validate SSL certificates.
* Allow clients to specify an ID as part of username (user[@identifier][/network]). Currently not used, but modules can use it.
* Add alias module for ZNC-side command interception and processing.
* Support character encodings with separate settings for networks, and for clients. It replaces older charset module, which didn't work well with webadmin, log and other modules.
* Support X-Forwarded-For HTTP header, used with new TrustedProxy setting.
* Add URIPrefix option for HTTP listeners, used with reverse proxy.
* Store query buffers per query the same way it's done for channels, add new option AutoClearQueryBuffer.
* Add DisableChan command to *status, it was available only in webadmin before.
* Allow wildcards in arguments of Help commands of *status and various modules.
* Support IRCv3.2 batches, used for buffer playbacks.
* Support IRCv3.2 self-message.
* Remove awaynick module. It's considered bad etiquette.
* Add JoinDelay setting, which allows a delay between connection to server, and joining first channel. By default it joins immediately after connect.
* Make Detach, EnableChan and DisableChan commands of *status accept multiple channels.
* znc-buildmod: Build output to the current working directory.
* Wrap long lines in tables (e.g. in Help or ListAvailMods commands).
* Support ECDHE if available in OpenSSL.
* Report ZNC version more consistently, add HideVersion setting, which hides ZNC version from public.
* Bump compiler requirements to support C++11. This means GCC 4.7+, Clang 3.2+, SWIG 3.0.0+.
