* The `general::dots_in_ident` configuration directive has been renamed to
  `general::specials_in_ident` and now covers the '-' and '_' characters in
  addition to '.'
* Fixed issue with clients connected from IPv6 localhost that, depending on the
  system's getaddrinfo() implementation, could lead to a crash of remote servers
* For a full list of all changes in this release, see <https://git.io/JtkgL>


-- Noteworthy changes in version 8.2.37 (2020-12-26)
* Implemented IRCv3 `CAP 302`

* For a full list of all changes in this release, see <https://git.io/JtkgJ>

* The old WATCH implementation has been replaced with IRCv3.2 MONITOR. For this,
  the `general::max_watch` configuration directive has been renamed to
  `general::max_monitor`.
* User mode `B` has been implemented. Clients with that mode set are marked as a
  bot in both `WHOIS` and `WHO`. This mode can only be set by IRC operators (as
  long as the `bot` directive is set in `general::oper_only_umodes`), servers,
  and services.
  This mode can for example be used to mark HOPM as official network bot.

  `full` have been removed from `general::oper_only_umodes`, `general::oper_umodes`,
  and `operator::umodes`.
* User mode +b (bots) has been replaced with +f (flood). Spam/flood notices are now

-- Noteworthy changes in version 8.2.30 (2020-03-01)
* `QUOTE HELP extban` didn't work because the extban help file hasn't been
  installed properly during `make install`
* Fixed broken libcrypto detection which caused the ircd not to work with
  OpenSSL under certain circumstances
* Extban $n of type `acting` has been implemented. This extban prevents
  matching users from changing their nick while in the channel. Users

  * `$c:<channel>`   Matches users that are on the given channel. An additional
                     prefix of either @, %, or + can be specified to test for
                     certain channel privileges.
  * `$o:<class>`     Matches IRC operators that have joined a class
                     matching the mask.
  * `$r:<realname>`  Matches users with a matching realname.
  * `$s:<server>`    Matches users that are connected to a server matching the mask.
  * `$u:<modes>`     Matches users having the specified user modes set or not set.
  * `$z:<certfp>`    Matches users having the given TLS certificate fingerprint.

  Acting:

  * `$j:<banmask>`   Prevents matching users from joining the channel.
  * `$m:<banmask>`   Blocks messages from matching users. Users with voice
                     or above are not affected.

  For more details, see `help/extban`.

* The `--enable-openssl`, `--enable-gnutls` switches, and their disabling counterparts
  `--disable-openssl` and `--disable-gnutls`, have been replaced with the `--with-tls`
  switch which takes one of the following options: `openssl`, `wolfssl`, `gnutls`,
  and `none`.
  If nothing has been specified, configure tries to autodetect in the following order:
  OpenSSL/LibreSSL -> GnuTLS -> wolfSSL.
* Fixed segfault with GnuTLS/libgmp in case there's no DH parameters file
  defined in `serverinfo::ssl_dh_param_file` or if that file is missing

    `ssl_dh_param_file` -> `tls_dh_param_file`
    `ssl_dh_elliptic_curve` -> `tls_supported_groups`
    `ssl_cipher_list` -> `tls_cipher_list`
    `ssl_message_digest_algorithm` -> `tls_message_digest_algorithm`

  instead of updating existing ones that are already in use
* For a full list of all changes in this release, see <https://git.io/fjEbq>


-- Noteworthy changes in version 8.2.25 (2019-04-24)
* The `class::number_per_ip`, `class::max_local` and `class::max_global`
  configuration directives have been replaced with just `class::number_per_ip_local`

  extended ban list size specified with the new `channel::max_bans_large`
  configuraton option. This mode can be set only by IRC operators or servers.

-- Noteworthy changes in version 8.2.13 (2016-02-02)

  following channel {} block configuration directives:
  `default_split_user_count`, `default_split_server_count`,
  `no_create_on_split`, `no_join_on_split`

  ISO 3166 alpha-2 two letter country code, or a nick!user@host mask.

  commands with the new `MODULE` command which can be fed with the `LOAD,`

  all modules
* Added back server notice when a client tries to obtain a reserved nick name

* Implemented full services support, including but not limited to the
  following changes:
  - Added `SVSNICK`, and `SVSMODE` command handlers
  - Added service stamps to `NICK`/`UID` messages
  - Added SVS to server capabilities (`CAPAB`). SVS capable servers can
    deal with extended `NICK`/`UID` messages that contain service IDs/stamps.
  - Changed rejected client notices to go to new user mode +j. These
    previously used user mode +r.
  - Added user mode +r (registered nick) and channel mode +r (registered channel)
  - Added user mode +R (only registered clients may send a private message)
  - Added channel mode +R (only registered clients may join that channel)

  - Added services {} block to `ircd.conf`
  - Added services_name directive to general {} block

  only be added via `ircd.conf`
* Added `globops`, `restart`, `dline`, `undline` and `module` IRC operator privilege flags.
  Read `doc/reference.conf` for further explanation of what these flags control
* Removed Idle-time klines
* Cleaned up modules API. Old modules won't work anymore
* Removed `general::burst_away` configuration directive. AWAY bursts are now
  controlled via `connect::flags` explicitly
* Introduced new logging subsystem including log rotation based on
  file sizes. Log timestamp format is ISO8601 now
* Added support for remote D-lines
* Added user mode +H which is basically a replacement for the hidden_admin and
  `hidden_oper` operator flags. With user mode +H, IRC operator status can now
  be hidden even on remote servers
* Added CIDR support for operator {} blocks
* Removed the servlink program. ircd-hybrid can now make use of
  SSL/TLS for inter-server communication.
  NOTE: compressed server links are of course still available, but a SSL/TLS
  connection is required, as compression is now handled via OpenSSL
* Removed `ssl_server_protocol` configuration directive and
  added `ssl_client_method` and `ssl_server_method` instead.
  Both of these options can now be changed at runtime
* IRC operator login IDs are no longer limited to NICKLEN*2
* Removed `channel::burst_topicwho` configuration option. This feature is now
  enabled by default
* `STATS Y|y` now reports CIDR limits as well
* Added `m_webirc.c` to `contrib/`
* Overall code cleanup and speed improvements
