Mindjet is approaching the release of MindManager 8.2. You can read more about it and download the latest BETA via Mindjet's Blog. http://blog.mindjet.com/
We've been actively testing TPAssist 2007 (v1.6.8) and TPAssistCapture (v1.2.3) with MindManager 8.2 (build 302) and thus far have seen no issues.
Feel free to try MindManager 8.2 yourself.
Download TPAssist 2007 here: http://www.tpassist.com/Downloads/
Note: as with MindManager 8.1, TPAssist customer who are also using the Outlook Integrated Linkage Module (OLIM) must wait for the next update for TPAssist 2007. This is because TPAssist 2007 must be compiled against specific versions of MindManager in order for the Outlook 2003/2007 add-in to load correctly.
