I am considering buying Start10 after trying the trial version. 

But will I get FREE updates as Start10 point-releases become available, or will I have to keep paying for it with every release?

I ask because with the latest Win10 1511 release some start10 features either didn't work or played-up.  (For example, I had the Win10 'Settings' on the start10 'modern' menu but it dissapeared after 1511 upgrade happened and didn't come back.)  So changes to Win10 make Start10 unstable and free updates to Start10 would be important to me.
