 PyLink is an extensible, plugin-based IRC services framework written in Python. It aims to be:

 These IRCds (in alphabetical order) are frequently tested and well supported. If any issues occur, please file a bug on the issue tracker.
 
-* [charybdis](https://github.com/charybdis-ircd/charybdis) (3.5+) - module `ts6`
+* [InspIRCd](http://www.inspircd.org/) (2.0 - 3.x) - module `inspircd`
-    - For KLINE support to work, a `shared{}` block should be added for PyLink on all servers.
-* [InspIRCd](http://www.inspircd.org/) 2.0 - 3.x - module `inspircd`
     - Set the `target_version` option to `insp3` to target InspIRCd 3.x, or `insp20` to target InspIRCd 2.0 (currently the default).
     - For vHost setting to work, `m_chghost.so` must be loaded. For ident and realname changing support, `m_chgident.so` and `m_chgname.so` must be loaded respectively.
     - Supported channel, user, and prefix modes are negotiated on connect, but hotloading modules that change these is not supported. After changing module configuration, it is recommended to SQUIT PyLink to force a protocol renegotiation.
 * [Nefarious IRCu](https://github.com/evilnet/nefarious2) (2.0.0+) - module `p10`
     - Note: Both account cloaks (user and oper) and hashed IP cloaks are optionally supported (`HOST_HIDING_STYLE` settings 0 to 3). Make sure you configure PyLink to match your IRCd settings.

 ### Extended support
 
 Support for these IRCds exist, but are not tested as frequently and thoroughly. Bugs should be filed if there are any issues, though they may not always be fixed in a timely fashion.

+    - For GLINEs to propagate, the `AllowRemoteOper` option must be enabled in ngIRCd.
+    - `+` (modeless) channels are not supported, and should be disabled for PyLink to function correctly.
+    - For use with Relay, the `CloakHostModeX` setting will work fine but `CloakHost` and `CloakUserToNick` are *not* supported.

+### Legacy extended support
+
+Support for these IRCds was added at some point but is no longer actively maintained, either due to inactive upstream development or a perceived lack of interest. We recommend migrating to an IRCd in the above two sections.

 * [beware-ircd](http://ircd.bircd.org/) (1.6.3) - module `p10`
     - Because bircd disallows BURST after ENDBURST for regular servers, U-lines are required for all PyLink servers. Fortunately, wildcards are supported in U-lines, so you can add something along the lines of `U:<your pylink server>:` and `U:*.relay:` (adjust accordingly for your relay server suffix).
     - Use `ircd: snircd` as the target IRCd.
     - Halfops, `sethost` (`+h`), and account-based cloaking (`VHostStyle=1`) are supported. Crypted IPs and static hosts (`VHostStyle` 2 and 3) are NOT.

 ### Clientbot
 
-Since v1.0, PyLink supports connecting to IRCds as a relay bot and forwarding users back, similar to Janus' Clientbot. This can be useful if the IRCd a network used isn't supported, or if you want to relay certain channels without fully linking with a network.

 For Relay to work properly with Clientbot, be sure to load the `relay_clientbot` plugin in conjunction with `relay`.
