-This is charybdis 4.1.3-dev, Copyright (c) 2005-2018 Charybdis team.
+This is solanum 1.0-dev.
 See LICENSE for licensing details (GPL v2).
 
+## solanum-1.0
+
+Includes changes from charybdis-4.1.3-dev.
+
+**This release includes breaking changes from charybdis 4.x.** Please pay close attention to
+bolded warnings in the full release notes below.
+
+### build
+- Add `--with-asan` to configure to produce an ASan instrumented build
+
+### server protocol
+- **Breaking:** Don't implicitly abort SASL when connection registration handshake completes;
+  requires updating atheme to include https://github.com/atheme/atheme/pull/833.
+- OPER is now propagated globally, as :operator OPER opername privset
+
+### user
+- **Breaking:** invite-notify is now enabled by loading the invite-notify extension
+- Prioritise older, more important client capabilities for clients that can only accept
+  one line of CAP LS
+- Add the solanum.chat/realhost vendor capability (provided by extensions/cap\_realhost)
+- Add the solanum.chat/identify-msg vendor capability (provided by extensions/identify\_msg)
+- Server-side aliases preserve protocol framing characters
+- Add the +G user mode for soft callerid (implicitly allow users with a common channel)
+- /invite no longer punches through callerid
+- invite-notify now works
+- Rejectcached users are now sent the reason of the ban that caused their reject in most cases
+- Rejectcache entries expire when their corresponding K-lines do
+- One-argument /stats and zero-argument /motd are no longer ratelimited
+- Channel bans don't see through IP spoofs
+- Global /names now respects userhost-in-names
+- The `$j` extban is no longer usable inside ban exceptions
+- TLSv1 connections are accepted. They can still be disabled using OpenSSL config if you don't
+  want them. TLSv1 existing is not thought to be a threat to up-to-date clients.
+
+### oper
+- **Breaking:** Kick immunity for override is now its own extension, override\_kick\_immunity
+- **Breaking:** /stats A output now follows the same format as other stats letters
+- **Breaking:** helpops now uses +h instead of +H
+- **Breaking:** sno\_whois and the spy\_ extensions have been removed
+- **Breaking:** Using /wallops now requires the oper:wallops privilege instead of oper:massnotice
+- Opers now have their privset (identified by name) on remote servers
+- Oper-only umodes are refreshed after rehash and /grant
+- Extension modules can be reloaded
+- Override no longer spams about being enabled/disabled. It continues to spam on each use.
+- Add /testkline, which has the same syntax as /testline but doesn't check if the mask is ilined
+- /privs is now remote-capable and can respond with more than one line
+- Most commands now respect oper hiding
+- Massnotice (notice/privmsg to $$.../$#...) now alerts opers
+- Massnotice no longer imposes any restrictions on the target mask
+- /kline and /dline are hardened to invalid inputs
+- K/D-lines are more consistent about checking for encoded ipv4-in-ipv6 addresses
+- Add extensions/drain to reject new connections
+- Add extensions/filter to filter messages, parts and quits with a Hyperscan database
+- Add extensions/sasl\_usercloak to interpolate SASL account names into I-line spoofs
+
+### conf
+- **Breaking:** Completely overhaul oper privs. All privset configs will need to be rewritten.
+  See reference.conf for details.
+- Add the `kline_spoof_ip` I-line flag to make any spoof opaque to K-line matching
+- Add general::hide\_tkline\_duration to remove durations from user-visible ban reasons
+- Add general::hide\_opers, which behaves as if all opers have oper:hidden
+- Add general::post\_registration\_delay
+- Add general::tls\_ciphers\_oper\_only to hide TLS cipher details in /whois
+- Add channel::opmod\_send\_statusmsg to send messages allowed by +z to @#channel
+- Add class::max\_autoconn, with the behaviour of class::max\_number for servers prior to
+  charybdis 4
+- Add `secure {}` blocks. Networks listed in a secure block gain +Z and can match `need_ssl` I-
+  and O-lines.
+- Remove general::kline\_delay
+- If m\_webirc is loaded, connections that try to use a webirc auth block as their I-line will
+  be disconnected on registration
+
+### misc
+- **Breaking:** WEBIRC now processes the "secure" option as specified by IRCv3. Web gateways that
+  do not set this option will need to be updated or their connections will show as insecure.
+- Successfully changing IP with WEBIRC now drops an identd username
+
+### code
+- Channel lists are now kept sorted. A for-loop macro, `ITER_COMM_CHANNELS`, is introduced to
+  efficiently compare two such lists.
+
+
 ## charybdis-4.1.2
 
 ### user
-- src/s_user.c: don't corrupt usermodes on module unload/reload
+- src/s\_user.c: don't corrupt usermodes on module unload/reload

-Charybdis is designed with portability in mind, but does not target older systems nor those of solely academic
-interest.
-
-Do note that operating systems are only supported if they are supported by their vendor.
-
-## Tier 1
-
-These platforms are the best supported, and should always work. They are actively tested. If you encounter
-problems, please file a bug.
-
-* FreeBSD 10.x and above (i386 and amd64)
-* Linux 2.6.x and above with glibc or musl (i386, x86_64, and ARM)
-* macOS 10.7 and above
-* Windows Vista/Server 2008 and above (x86 or x64)
-
-## Tier 2
-
-These platforms are supported and occasionally tested, and most features should work, but this is not
-guaranteed. If you find any problems, file a bug, but as these are not regularly tested platforms, a timely
-resolution may not be possible.
-
-* DragonflyBSD 4.4 and above (i386)
-* Linux with uClibc (i386 or x86_64)
-* NetBSD 6.1.x and above (i386, amd64)
-* OpenBSD 5.6 and above (i386, amd64)
-* Solaris 10 and above (i386)
-
-## Tier 3
-
-Anything else that hasn't been tested. Charybdis may or may not work on it; patches welcome if they don't.
+Solanum is developed on Linux with glibc, but is currently portable to most POSIX-compatible operating systems.
+However, this portability is likely to be removed unless someone is willing to maintain it.  If you'd like to be that
+person, please let us know on IRC.

+Connecting servers
+==================
+
+Servers can be connected together to improve redundancy, distribute bandwidth,
+lower latency, and connect network services.
+
+This document is an introduction to connecting servers. It assumes you are
+already somewhat familiar with Solanum's configuration (if not, read
+:file:`ircd.conf.example`, and set up your own server by editing it
+and running Solanum).
+
+Solanum uses the TS6 protocol, and can only be connected with other servers
+using this protocol. We recommend you only connect Solanum with other Solanum
+instances.
+
+Unlike some other IRCd implementations, all connections are reciprocal in
+Solanum, which means a single configuration block is used for both incoming
+and outgoing connections.
+Additionally, the same ports are used for server and client connections.
+
+Creating servers
+----------------
+
+If you already have a server running, copy its configuration to a new machine,
+and edit ``serverinfo`` for the new server. In particular, you must change the
+``name`` and ``sid``, but keep the same ``network_name``.
+We recommend you keep both configurations in sync using some external
+configuration management systems, so server configurations do not drift apart
+over time, as you change them.
+
+For each of the two servers, you must create a ``connect`` block to represent
+the connection with the other server. For example, if you have servers A and B
+respectively at a.example.org and b.example.org, use respectively::
+
+   serverinfo {
+           name = "a.example.org";
+           // ...
+   };
+
+   connect "b.example.org" {
+           host = "203.0.113.2";
+           port = 6666;
+
+           send_password = "password";
+           accept_password = "anotherpassword";
+
+           flags = topicburst, autoconn;
+
+           class = "server";
+   };
+
+and::
+
+   serverinfo {
+           name = "b.example.org";
+           // ...
+   };
+
+   connect "a.example.org" {
+           host = "203.0.113.1";
+           port = 6666;
+
+           send_password = "anotherpassword";
+           accept_password = "password";
+
+           flags = topicburst, autoconn;
+
+           class = "server";
+   };
+
+Note the reversed passwords.
+
+The ports should be any of the ports defined in a ``listen {}`` block of the
+other server.
+
+The ``autoconn`` flag indicates a server should automatically connect using
+this ``connect {}`` block. At least one of the two servers should have it,
+or the servers won't try to connect.
+
+If you are connecting servers over an unencrypted link, you should use SSL/TLS
+for the connection; see :file:`reference.conf`.
+
+
+Connecting services
+-------------------
+
+In addition to regular servers, you can also connect service packages such
+as atheme-services.
+
+These services typically do not accept incoming connections, and connect to
+one of the existing servers of the network.
+
+To allow connections from such a service server, you should create
+a new ``connect {}`` block for this package, on the server the services
+will connect to::
+
+   connect "services.example.org" {
+           host = "localhost";
+           port = 6666;
+
+           send_password = "password";
+           accept_password = "anotherpassword";
+
+           flags = topicburst;  // No autoconn, services don't accept incoming connections
+
+           class = "server";
+   };
+
+And create the appropriate config in your services' configuration so that
+they connect to your server on the configured port, and from the configured
+hostname.
+
+For example, with atheme::
+
+   loadmodule "modules/protocol/solanum";
+
+   uplink "a.example.org" {
+           host = "localhost";
+           port = 6666;
+           send_password = "anotherpassword";
+           receive_password = "password"
+   };
+
+Finally, you must configure all servers in your network to recognize the
+services server::
+
+   service {
+           name = "services.example.org";
+   };

+extensions/filter module documentation
+--------------------------------------
+
+The filter extension implements message content filtering using 
+solanum's hook framework and Intel's Hyperscan regular expression
+matching library.
+
+It requires an x86_64 processor with SSSE3 extensions.
+
+To operate, the filter requires a database of regular expessions
+that have been compiled using the Hyperscan library's 
+hs_compile_multi() or hs_compile_ext_multi() functions. 
+
+The command SETFILTER is used to manage operation of the filter and to
+load compiled Hyperscan databases.
+
+General documenation of SETFILTER is available using the 'HELP SETFILTER'
+command.
+
+For each expression in the database, the three least significant bits 
+of the expression ID are used to indicate which action the ircd should
+take in the event of a match:
+
+001 (1) DROP   - The message will be dropped and the client will be sent
+                 an ERR_CANNOTSENDTOCHAN message.
+010 (2) KILL   - The connection from which the message was recevied will
+                 be closed.
+100 (4) ALARM  - A Server Notice will be generated indicating that an
+                 expression was matched. The nick, user, hostname and
+                 IP address will be reported. For privacy, the expression
+                 that has been matched will not be disclosed.
+
+Messages are passed to the filter module in a format similar to an
+IRC messages:
+
+0:nick!user@host#1 PRIVMSG #help :hello!
+
+The number at the start of the line indicates the scanning pass:
+Messages are scanned twice, once as they were received (0), and once
+with any formatting or unprintable characters stripped (1).
+
+By default, 'nick', 'user' and 'host' will contain *. This behaviour
+can be changed at build time if filtering on these fields is required.
+
+The number after the # will be 0 or 1 depending on whether the sending
+client was identified to a NickServ account.
+
+The process for loading filters is as follows:
+
+1. The Hyperscan database is serialized using hs_serialize_database().
+2. A 'SETFILTER NEW' command is sent.
+3. The serialized data is split into chunks and base64 encoded. 
+   The chunk size needs to be chosen to ensure that the resuliting
+   strings are short enough to fit into a 510 byte IRC line, taking 
+   into account space needed for the 'SETFILTER +' command, check field, 
+   server mask, and base64 overhead.
+4. The encoded chunks are sent using 'SETFILTER +' commands
+5. Once the entire database has been sent, a 'SETFILTER APPLY' command
+   is sent to commit it.
