I had some problem installing this update on Win 10
1 - (I didn't save a screenshot, sorry) - some files with an extension .csv had problem to be written to the folder. Windows show a message with options

Try again (didn't work)
Skip this file (not recommended - I clicked on this option and have got the message with another csv file)
Cancel - it rolled installation back.

Restarted my computer, tried again with no problem.

Opened my project and for some reason got a warning from my Norton Antivirus about this

Apart from the few minor bug fixes and custom asthetics most of the improvements are aligned to expediting scripting and now almost negating any need to scroll through existing or other programs to remember syntax or what subs are associated with any function or attribute which makes us really lazy and efficient!
