Crashes in beta 7.48.168
UnrealIRCd-4.0.11 - irc1.unrealircd.org - no crash
InspIRCd-2.0 - irc.chatspike.net - no crash
ircd-ratbox-3.0.10 - irc.mzima.net (efnet) - no crash
charybdis-3.5.3 - irc.esper.net - crash
So I got a little clever on running the old beta versions and according to my testing:
7.47.489 - no crash
7.47.638 - crash
mIRC v7.47.638 Beta
1.Item 15,
https://forums.mirc.com/ubbthreads.php/topics/260026 Fixed /server password backward compatibility issue.
2.Item 22,
https://forums.mirc.com/ubbthreads.php/topics/260037 Now checks if /who for that #channel is already taking place and does
not resend it if waiting for reply.
Changed to use fixed T value of 995.
Changed to allow unrecognized T results to be displayed.
3.Item 17,18,21
https://forums.mirc.com/ubbthreads.php/topics/260040 Now only updates IAL after ^event.
4.Item 22, added 'l' option to WHOX parameters. This is not used by mIRC
but may be useful to scripts that parse the numeric reply.
5.Item 27,
https://forums.mirc.com/ubbthreads.php/topics/260014 Needed partial rewrite of IAL routines.
Both /ialmark and $ial().mark should work as before and be backward
compatible.
Needs testing.
6.Item 28, now faster when using just a nickname.
