UnrealIRCd 4.2.4 released (also fixes crash issue)
This release fixes a crash issue if UnrealIRCd is configured to use utf8 or chinese character sets in set::allowed-nickchars. We don't expect many users to run their IRCd with this enabled, as the utf8 support was tagged as experimental and the chinese/gbk implementation is incomplete.
This release also contains a number of other fixes and enhancements. In particular the reputation and connthrottle modules are now working better and there were some major Windows fixes. (Read more)

There have been so many changes in this and last few 4.0.x versions, it justifies calling this release UnrealIRCd 4.2.0. Marking the beginning of the 4.2 series, this release introduces features such as 'soft klines' and 'soft actions'. A significant number of optional modules are now loaded as default, including timed channel bans and textbans. Also, a lot more smaller changes are included in this release, such as fixes for TLSv1.3 and experimental WHOX support.

Currently more than 95% of the crashes reported to us are due to faulty 3rd party modules. Third party modules are modules coded by authors other than the UnrealIRCd team. We do not investigate such bug reports. These bugs are caused by and should be resolved by the module author(s). Keep this in mind if your server crashes: try unloading all (recently) installed 3rd party modules and see if the crash issue disappears. Also, check for updates of 3rd party modules, your crash issue may very well be fixed already.
Crash issue in UnrealIRCd: apply hot fix ASAP or upgrade to 4.0.11
UnrealIRCd versions 4.0.8 - 4.0.10 on *NIX can be crashed by a remote user. This is due to a buffer overflow issue. The issue is actually present in all UnrealIRCd versions but because the data overflows into unused variables after the buffer previously went undetected and caused no harm. [.] The Windows version does not crash. For *NIX, we have released a 'hot fix' which can patch your server without requiring an UnrealIRCd restart. Or you can upgrade to UnrealIRCd 4.0.11 (Read more)

If you are still running UnrealIRCd 3.2.x then this is a friendly reminder to upgrade to UnrealIRCd 4 before the end of the year. As announced a year ago, all support for UnrealIRCd 3.2.x will stop after December 31, 2016. This also means no more security updates. UnrealIRCd 4 is in use by many networks and has proven to be stable and reliable. Many third party modules have been converted as well. Upgrading from 3.2.x to 4.x should be relatively easy. Your configuration file can be updated to the new format automatically. (Read more)

Security: SASL security issue (UnrealIRCd 4.0.6 & 3.2.10.7 released)
A security issue was detected in a number of IRCd's, including UnrealIRCd.

While this only affects 2% of our userbase, for those networks which are affected this is a very serious issue. (Read more)
