YaBB 2.6.12 is now available at SourceForge at https://sourceforge.net/p/yabb/svn/HEAD/tree/trunk/ (download the 'snapshot') and https://sourceforge.net/p/yabb/svn/HEAD/tree/branches/2.6.12/ (download the 'snapshot').

This is basically a bug-fixed version of 2.6.11 with some security fixes converning the clicklog and log.txt.

Instructions: if you're running an unmodded version of 2.6.11 (or your only mods were the big fixes), simply replace the files in yabb2/Admin, yabb2/Help/English, yabb2/Languages/English/*.lng, yabb2/Sources, yabb2/Templates/default/*.template,  yabb2/Templates/default/Micon.def.

If your forum was modded - 2.6.11 mods should install without problems to 2.6.12.

There's 1 change to Templates/default/default.html

find

<div class="yabb_searchbox">{yabb searchbox}</div> 

replace with

{yabb searchbox} 

Moving the searchbox div to Subs.pm solves a bug with Setup.pl.

yabbfiles/Templates/Forum/default.css has also changed.
If you have edited the Fourm/default.css you'll need to add:

table.fixed {
     table-layout: fixed;
 }
 span.newlinks {
     height: 11px;
     display: inline-block;
     vertical-align: middle;
     -webkit-border-radius: 3px;
     -moz-border-radius: 3px;
     border-radius: 3px;
     background: -webkit-linear-gradient(top, #569dce, #3673b3);
     background: -moz-linear-gradient(top, #569dce, #3673b3);
     background: linear-gradient(#569dce, #3673b3);
 }

 span.newlinks_c {
     color: #fff;
     font-size: 8px;
     height: 11px;
     display: inline-block;
     vertical-align: top;
     padding: 0 4px;
 } 

span.newlinks and span.newlinks_c is for the non-graphics dependant 'new' marker.
