Hi everyone,

It has been only a month since previous release, but I'm happy to 
announce UnrealIRCd 6.1.7. The main purpose of this release is adding 
new features, such as ASN support, more flexible ban user { } and ban 
authentication { } blocks and more. See the release notes below for all 
details.


      Enhancements:

<https://github.com/unrealircd/unrealircd/blob/unreal60_dev/doc/RELEASE-NOTES.md#enhancements>

  * In the ban user { } <https://www.unrealircd.org/docs/Ban_user_block>
    and require authentication { }
    <https://www.unrealircd.org/docs/Require_authentication_block>
    blocks the |mask| is now a Mask item
    <https://www.unrealircd.org/docs/Mask_item>. This means you can use
    all the power of mask items and security groups and multiple
    matching criteria.
  * The GeoIP module now contains information about Autonomous System
    Numbers <https://www.unrealircd.org/docs/ASN>:
      o The asn is shown in the user connecting notice as |[asn: ###]|,
        is shown in |WHOIS| (for IRCOps) and it is expanded in JSON data
        such as JSON Logging
        <https://www.unrealircd.org/docs/JSON_logging> and JSON-RPC
        <https://www.unrealircd.org/docs/JSON-RPC> calls like |user.list|.
      o Can be used in Extended server ban
        <https://www.unrealircd.org/docs/Extended_server_bans>: |GLINE
        ~asn:64496 0 This ISP is banned|.
      o Can be used in security groups and mask items
        <https://www.unrealircd.org/docs/Mask_item> so you can do like:

        |require authentication { mask { asn { 64496; 64497; 64498; } }
        reason "Too much abuse from this ISP. You are required to log in
        with an account using SASL."; }|

      o In Crule <https://www.unrealircd.org/docs/Crule> functions as
        |match_asn(64496)|
      o Also available in regular extbans/invex, but normally users
        don't know the IP or ASN of other users, unless you use no
        cloaking or change set::whois-details::asn
        <https://www.unrealircd.org/docs/Set_block#set::whois-details>.
  * JSON-RPC <https://www.unrealircd.org/docs/JSON-RPC>: Similar to oper
    and operclass, in an rpc-user
    <https://www.unrealircd.org/docs/Rpc-user_block> you now have to
    specify an rpc-user::rpc-class. The rpc-class is defined in an
    rpc-class block <https://www.unrealircd.org/docs/Rpc-class_block>
    and configures what JSON methods can be called.
    There are two default json-rpc classes:
      o |full|: access to all JSON-RPC Methods
      o |read-only|: access to things like /server_ban.list/ but not to
        /server_ban.add/
  * set::spamfilter::except
    <https://www.unrealircd.org/docs/Set_block#set::spamfilter::except>
    is now a Mask item <https://www.unrealircd.org/docs/Mask_item>
    instead of only a list of exempted targets. A warning is created to
    existing users along with a suggestion of how to use the new syntax.
    Technically, this is not really new functionality as all this was
    already possible via the Except ban block
    <https://www.unrealircd.org/docs/Except_ban_block> with type
    spamfilter, but it is more visible/logical to have this also.
  * New option set::hide-killed-by
    <https://www.unrealircd.org/docs/Set_block#set::hide-killed-by>: We
    normally show the nickname of the oper who did the /KILL in the quit
    message. When set to |yes| the quit message becomes shortened to
    "Killed (Reason)". This can prevent oper harassment.
  * set::restrict-commands
    <https://www.unrealircd.org/docs/Restrict_commands>: new option
    |channel-create| for managing who may create new channels.
  * New option set::tls::certificate-expiry-notification
    <https://www.unrealircd.org/docs/Set_block#set::tls::certificate-expiry-notification>:
    since UnrealIRCd 5.0.8 we warn if a SSL/TLS certificate is (nearly)
    expired. This new option allows turning it off, it is (still) on by
    default.
  * Add the ability to capture the same data as Central Spamreport
    <https://www.unrealircd.org/docs/Central_spamreport> by providing an
    spamreport::url option.


      Changes:

<https://github.com/unrealircd/unrealircd/blob/unreal60_dev/doc/RELEASE-NOTES.md#changes>

  * IRCOps with the operclass |locop| can now only |REHASH| the local
    server and not remote servers.
  * Comment out some more in example.conf by default
  * Update shipped libraries: c-ares to 1.31.0, PCRE2 to 10.44, Sodium
    to 1.0.20


      Fixes:

<https://github.com/unrealircd/unrealircd/blob/unreal60_dev/doc/RELEASE-NOTES.md#fixes>

  * Crash when removing the |websocket| option on a websocket listener.
  * Silence some compiler warnings regarding deprecation of c-ares API
    in src/dns.c.
  * Memory leaks of around 1-2KB per rehash


      Developers and protocol:

<https://github.com/unrealircd/unrealircd/blob/unreal60_dev/doc/RELEASE-NOTES.md#developers-and-protocol>

  * We use numeric 569 (RPL_WHOISASN) for displaying ASN info to IRCOps:
    |:irc.example.net 569 x whoiseduser 64496 :is connecting from
    AS64496 [Example Corp]|
