Useless. * Cleared all aggressive warning flag errors from the code. Changes in 3.22b: * Autosetup handling interfered with 2.x and 1.x client authentication and has been reworked. Changes in 3.22a: * Applied hub level local-echo fix. * Bugfix in iced_privmsg applied. Changes in 3.22: * Protocol version taken back to 2. * can_forward changed from static int to bool. * broadcast and isbroadcast in forward function changed to bool variables. * Version check removed from imc_addnewmud.

Old ignore system had been removed. (!) - Added ban file to hold ban data. - Added IMC_BAN struct for data tables. - Added host field to IMC_CONNECTION to support IP address bans. - clientpassword checks connection host before allowing complete connection. - Bans can be added and removed using the autoupdate feature if enabled. * Control socket listens for 3 queued connections now instead of just 1. *boggle* * Added disconnect bool to IMC_CONNECTION struct to delay disconnect until after messages are sent. * Memory handling macros updated to the latest versions. * Default channel level now sent down by the hub with the ice-refresh packets. - This is used with the 3.20 client permissions system. * Added autoupdate field to imc_siteinfo_struct for config file control of update file. * Added private field to imc_siteinfo_struct to allow hubs to deny autoconn. Controlled by config file. * Added connects field to imc_siteinfo_struct for counting the number of connections in the config. * Added maxconnects field to imc_siteinfo_struct to allow control over how many muds can connect. Config file. * log() function renamed to imclog() to shut GCC 3.3.x up. * imc_saveconfig is only called by check_mudsfile if an update actually succeeded. * Network name can now be specified in the config file vs hardcoding in send_keepalive.
