Version 2.6.20 fixes a problem with slowness when importing waveforms (such as the Galbanum collection).

Just wondering if Synthmaster sent you an email for update like this. I've purchased the Synthmaster license by don't get any update information.
 
Thanks!

I received the newsletter Oct 17th, it included the update announcement, although 2.6.20 was announced here http://www.kvraudio.com/forum/viewtopic.php?f=1&t=422121 Oct. 7th. There is a link to sign up for their newsletter to the right above the menu on http://www.synthmaster.com/synthmaster.aspx. It is also possible to check for updates by clicking the Synthmaster logo in the upper right of the synth UI.

I got the newsletter yesterday, the 19th. I'm guessing addition to the mailing list is not automatic when you buy something. IIRC I did explicitly sign up for the newsletter.
