In Omniscope 2.8 we have combined the "File", "URL" and "Publish on visokio.com" output blocks into a single "Data file output" block. When you open this block you are given the option to specify whether you want to publish to a file, URL or to publish on visokio.com.
Files from version 2.7 will open in 2.8 with "legacy blocks" appearing. These output blocks will continue to execute, but you will not be able to change their configuration.
You will be able to convert them to the new block in order to configure, but after saving, this new block will not be backwards compatible with 2.7.
