Obsoleted means approximately the same thing as deprecated, except for verb subject.

  They’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in the software field it has long also been used to indicate things that actively don’t work any more because they’ve been replaced by something else.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.
