This update of CTools focuses on stabilizing the tools, and still contains a number of known bugs.
- People have reported issues with export UI classes not being found. This appears to be due to incomplete registry cache builds, possibly during cron. Typically a complete cache clear via drush fixes this, and update.php should also clear cache and fix this but does not seem to be able to. Sometimes disabling modules such as mini panels appears to fix it. This seems to be happening regardless of the CTools version.
- Taxonomy term selection in the taxonomy access selection rule and taxonomy context not working right.
- Multiple terms (i.e, 1+2+3 or 1,2,3) at taxonomy/term/%term not supported.
- There may still be little bits that have not been fully upgraded to 7. I keep thinking I have them all and then find a new one.
