InspIRCd v4 is still early in development!

If you use this branch you may experience crashes, weird behaviour, and unannounced breaking changes.

You probably want to use InspIRCd v3 instead.

The "chanhistory" Module (v4)


This module adds channel mode H (history) which allows message history to be viewed on joining the channel.


To load this module use the following <module> tag:
