The latest beta, mIRC v7.31, can be downloaded here
and includes the following changes:
1.Fixed editbox buffer bug that was not storing an edited line if you pressed the up key.
2.Fixed incremental search not working correctly in channels list window.
3.Changed email catcher to be more strict when determining whether something looks like an email address.
4.Fixed installer issue that may been the cause of popups.ini files being overwritten in some situations.
5.Added installer command line options /DESKTOP, /NODESKTOP, /STARTMENU and /NOSTARTMENU to enable/disable creation of shortcut icons.
6.Added "On Top" menu item to the View menu as users have difficulty finding it in the system menu when it is enabled.
7.Changed the "File changed" dialog so that it is closed automatically if a load/reload command applies to the same file.
8.Extended $encode/$decode to support blowfish. By default, the method is compatible with OpenSSL and uses CBC, key hashing, a random salt and PKCS#5 padding (see versions file for more details).
9.Fixed SSL caching bug that may have required repeat acceptance of certficates on some networks. The cache now stores the IP address of the associated certificate.
10.Changed connection retry method so that if a connection attempt to an SSL server fails, and the server is part of an IP pool, the next retry will use the same SSL port.
11.Enabled DPI awareness to prevent Windows applying display scaling to mIRC. This should resolve the blurry interface and font issues when non-standard DPI display settings are used. A number of GUI-related features needed to be updated to cater for this change, eg. fonts now use internal defaults of points versus logical sizes. This may affect scripts that use dialogs and /draw on systems with non-standard DPI settings.
12.Fixed drag-drop bug that may have caused a gpf when switching windows between MDI/desktop mode.
13.Added MONITOR protocol support for the notify list. mIRC will use MONITOR automatically if it is listed in the 005 numeric.
14.Fixed "Check for update" dialog display bug that occurred when the connection to the website timed out.
15.Fixed $& indentation bug in scripts editor dialog.
16.Changed notify list to dynamically switch between WATCH/MONITOR and ISON when the number of nicks in the notify list is within/beyond the WATCH/MONITOR limit set by the server.
17.Optimized switchbar and treebar display speed.
18.Fixed switchbar "auto" lines feature being disabled when switchbar is repositioned. It is now only disabled if switchbar is resized vertically.
19.Fixed timestamp bug that may have caused a gpf in some situations if your timestamp was very long.
20.Fixed timestamp part of a message not being wrapped correctly when message is initially displayed in a window.
21.Fixed mIRC not handling mouse buttons correctly in some situations if the user's system is configured to swap mouse buttons.
22.Changed the way the window buffer is trimmed when it reaches the maximum number of lines set in the Options/Other dialog.
23.Added /close -lk to close channels list and links list windows, however note that channels list window cannot be closed if it is currently listing.
24.Optimized SSL routines.
25.Added SSL identifiers $sslversion, $ssldll and $ssllibdll.
26.Added logging dialog option to enable/disable automatic logging of status windows.
27.Changed reload log feature so that it is enabled by default for channels and chats.
