Searching through the user manual today, I came across this:
https://docs.inductiveautomation.com/display/DOC79/Timer+Scripts+-+Deprecated
Just to be clear, are timer scripts deprecated, or just this manual page? There’s no other mention of deprecation that I could find.
Probably just the manual page. Current page is here
I’ve noticed that there is a large number of other topics that are deprecated as well. Searching for ‘Deprecated’ give 5 pages of results!
E.g.
Navigation Functions - Deprecated
Shutdown Scripts - Deprecated
Scripting Basics - Deprecated
… etc.
What does this mean?
PS. I’m looking at the latest doc on the inductive auto server (https://docs.inductiveautomation.com)
That page in the manual has been replaced. Poor usage of the word "deprecated".
How do I get the latest page?
Search for that title without the “deprecated”.
Ah, of course 
It looks like they’re rewriting sections and re-organising/renaming sections as well
