RE: [EXTERNAL] Re: Deprecated API Removal timeline?

I think the hope here is that the deprecated API elements in 3.5 are not being used when you move to 3.5 (and complete your migration). Once that is done, AFAIK, there is no actual effort needed to move to the 4.0 API after removal. Unless you keep using deprecated APIs. The decision is not finalised, but expect rapid movement on it.

Note that 3.5 is an LTS so it will be supported for 5 years.

Obviously upgrading to the newer API is recommended sooner than that. 

 

Why?  My employer plans to upgrade to 3.5 soon, and then is very unlikely to upgrade to 4.x for three or four years, at which point we will go to the latest current LTS.  What benefit is there in using the newer API before then.  (“It can do new shiny things” doesn’t really count.  I don’t need to do those new shiny things.)
