This version of mIRC is primarily a security release. mIRC users are advised to upgrade to this version due to a security issue related to very long nicknames on non-standard servers.
Several other small issues have also been fixed in this release.
Although this is a minor update, it includes important changes and all users are advised to upgrade.
Full list of Fixes, Changes and Additions:
1.Fixed nickname bug where very long nicknames (hundreds of characters
in length) sent by the server would cause mIRC to crash.
2.Updated to PCRE v7.8 and OpenSSL 0.9.8i libraries.
3.Added Script Editor option to disable line numbers.
4.Fixed /toolbar bug where setting a bitmap for a default button was
not working correctly.
5.Added custom dialog support for "rich" editbox property that allows
an arbitrary "limit" on the amount of text.
6.Fixed window listbox display bug when moving the horizontal scrollbar
all the way to the right.
