RLS is no longer deprecated, but removed. “Deprecation warning” means “FYI, you shouldn’t be using this, but it’ll still work for now”. This is an obsolescence notification, not a deprecation warning.
I fear we’re losing the fight for the meaning of the word “deprecate”. Yet we have no other word or even phrase to convey what it has historically meant.
- pie_flavor 4y agoObsoleted means approximately the same thing as deprecated, except for verb subject.
- chrismorgan 4y agoThey’re often similar, but there are very important differences. (And I led with the word “removed” rather than “obsoleted” for a reason; perchance it was unwise to use the term obsolescence at all.) Obsolescence is ambiguous. In common usage it means a thing is not maintained and will generally become harder and harder to use due to the lack of maintenance and support, so that at some point it will probably stop working and be unfixable. But especially in the software field it has long also been used to indicate things that actively don’t work any more because they’ve been replaced by something else. In short, “obsolete” already serves as what people are ruining “deprecated” to mean: maybe it works, maybe it doesn’t, but sooner or later it won’t work. Deprecation, however, must not signify removal. It is purely a form of discouragement of something that still works, at least for now.
