I just upgraded to Yosemite and my commercial licensed version of LRTimelapse will not work any more. It prompts me to re-install an older version of Java (6), which is supposed to be a security nightmare.

Guenther, any suggestions on how to work around this? thanks, Bob Krist

Yes, upgrade to LRTimelapse 3, you can get an Upgrade for your license from http://lrtimelapse.com/shop
LRTimelapse 3 supports the latest MacOS and brings its own, modern Java. No need to install the legacy one.
Apart from this, there are lots of new features, better workflows and the new render engine that you will take profit from.

Thanks, Gunther. I'll look into the update after all the Christmas bills are paid:-).
