mojoPortal 2.2.6.7 is now available on the download page.
This is primarily a bug fix release. There was a change in the search engine architecture in recent versions that did not work in Medium Trust hosting environments that has now been fixed.
It seems like a constant battle to avoid medium trust issues, so I started a small document here with some notes for developers about things to avoid that can cause problems under medium trust.

Its not comprehensive so if anyone else has any suggestions for things to list on this page let me know. Sometimes its surprising when seemingly innocuous things don't work under medium trust. The problem we encountered was when we changed the search engine to use a queue for writing/updating the search index to ensure things happen in correct sequence. We were serializing our task object into a row in the database then our little task service would deserialize it and run it on a new thread in the background. As it turned out the SoapFormatter we were using to do the serialization throws a security exception under medium trust so you can't use it. I had to re-work the code to use the XmlSerializer.
Since a lot of people are hosted in medium trust I thought it important to get this fix out quickly.
This release also fixes a few other minor bugs as mentioned in the forums. I was surprised how many people are experimenting with our WebStore feature. Several bug fixes and improvements have been made in WebStore. Most of the bugs were only affecting the MS SQL version, whereas the store on this site is runningunder MySql
UPDATE: I've just uploaded a new set of files versioned 2-2-6-7-b because a significant bug was found today in the task framework. The changes I made to the way we serialize tasks to fix the medium trust issue introduced a bug that allowed multiple instances of the same task to run at the same time and this would use up additional threads from the threadpool, potentially causing hangs and performance problems. I also upgraded to FCKeditor 2.6.3.
