As Chris mentioned on his blog - there is an update out for ExBPA.Config.xml, bringing it to version 18.104.22.168.
Under most circumstances, ExBPA should auto-detect the new version of the rules file and prompt you to download. If this does not occur, you can download and apply the ExBPA Web Update Pack from:
Paul Bowden brought up a point about this release that I wanted to cover a bit more after discussing it with him.
As you might have noticed, the "major" config version has changed from "5" to "6". Meaning, it used to be 1.5.x.x and now it is 1.6.x.x.
The significance of this in "real life" is that the previous runs of ExBPA cannot be reanalyzed with this new set of rules.
Previous EXBPA reports will open just fine after you upgrade to this version of rules, but you can't use the new XML to re-analyze a previous (old) report.
For example, if you used 22.214.171.124 to do a scan and then upgraded to 126.96.36.199 of the XML, the next time you opened the previous scan, the 188.8.131.52 rules would be applied to the old run; and you may see some new problems show up. However, if you did a scan with 184.108.40.206 and then upgraded to 220.127.116.11 of the XML, then when you open the old run, you'll see the same issues as before. New issues that the new set of rules might trigger will not show up unless you re-run the scan completely.
Hope that helps,
