What's new in this version:

- Changed the way Windows system libraries are loaded to prevent DLL hijacking
- Changed CTCP PING to not reply to text containing CTCP control codes to mitigate NAT-AGAIN Linux kernel NAT bug
- Added tray tip warning on startup if mIRC has been minimized to the system tray but Windows has hidden its icon

Fixed:
- colons being stripped out of nick, alternative nick, user, emails, /nick, and server list entries
- /hsave -i intermittent crash bug caused by a data race / race condition across multiple threads
- tab key evaluation of identifiers in editboxes that contain multiple CR/LF-delimited lines
- nested single-line while loop break bug
- /socklisten -pu with UPnP, IPv6 address, and dual stack not opening an IPv4 UPnP port on the router
- Aero theme bug where if /window +b was used, a miniature titlebar was being drawn
- alternative nick bug when left empty in connect dialog
- Updated CA root certificates cacert.pem file
