Changes since 8.2.45:

• • Noteworthy changes in version 8.2.46 (2025-01-22)
• The user mode subsystem now supports dynamic registration and unregistration of user modes. This allows modules to register and unregister their own user modes, making the system more flexible and modular.

• The INFO command output now shows entries from the admin {} config block
• The WALLOPS command has been removed
• The serverinfo::motd_file configuration directive has been added, allowing the Message of the Day (MOTD) file path to be customized instead of hardcoded
• The channel::max_kick_length configuration directive has been added, allowing servers to specify the maximum length of a KICK message that the server will accept from a client.
