Yes, the upgrade licenses (for anyone who purchased Oct 31 or later) were sent Wednesday evening. (It took a while to generate all the upgrades and get them mailed.)
If you haven't received it by now, check your spam mailbox, any auto-mail-filing, etc. If you really never received it (and you qualify for a free upgrade), email
sales@omnigroup.com and we'll get it straightened out.
