Hi everyone,

Unfortunately we had to release a fix 2 days after 5.0.5 release. This
reverts the previously mentioned UTF8 support in Spamfilter. The reason
for this is that there is currently a bug in the PCRE2 regex library
which causes the IRCd to hang/freeze on certain regexes, in particular
ones which use () groups. Once PCRE2 has fixed this issue and has done
more tests, we may be able to reintroduce the issue in a future version,
but for now it is gone.

UnrealIRCd 5.0.5(.1) is now available. This releases focuses mainly on
new features, while also fixing a few bugs. See the release notes
<https://github.com/unrealircd/unrealircd/blob/d1d0237f2df2fc83d8dc235ed139d45de342a138/doc/RELEASE-NOTES.md#unrealircd-5051-release-notes>
for full details.

*UnrealIRCd 5!*

After more than 6 months of hard work, UnrealIRCd 5 was released in
December 2019 and is now our "stable" branch. In particular I would like
to thank Gottem and 'i' for their source code contributions and PeGaSuS
and westor for testing releases.
When we transitioned from 3.2.x to 4.0.0 there were 175,000 lines of
source code added/removed during 3 years of development. This time it
was 120,000 lines in only 8 months, a major effort!

A short summary of release highlights is available here
<https://www.unrealircd.org/docs/What%27s_new_in_UnrealIRCd_5>. The full
release notes are available here
<https://github.com/unrealircd/unrealircd/blob/d1d0237f2df2fc83d8dc235ed139d45de342a138/doc/RELEASE-NOTES.md#unrealircd-5>.
If you have some spare time, we recommended reading the full release
notes (the new and changed sections, anyway) so you don't miss out on
anything.

If you are upgrading from 4.x to 5.x then it would be wise to read
Upgrading from 4.x <https://www.unrealircd.org/docs/Upgrading_from_4.x>.
In any case, be sure to upgrade your services package first! (if you use
any). UnrealIRCd 5 is known to work with the following services:

  * anope <https://www.anope.org/> (version 2.0.7 or higher) - with the
    "unreal4" protocol module
  * atheme <https://atheme.github.io/atheme.html> (version 7.2.9 or
    higher) - with the "unreal4" protocol module

As always, you can download UnrealIRCd from https://www.unrealircd.org/

*UnrealIRCd 4 is still supported*

UnrealIRCd 4 will be maintained until 31 December 2020 (security fixes
only). After that date UnrealIRCd 4 is no longer supported
<https://www.unrealircd.org/docs/UnrealIRCd_4_EOL>.
Admins are recommended to upgrade to UnrealIRCd 5 in the first half of 2020.
