* [InspIRCd](http://www.inspircd.org/) 2.0, 3.x [BETA] - module `inspircd`

- Both InspIRCd 2.0 and 3.x are supported by this module.

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.
