You’re absolutely right. In my mind “feature parity” got garbled into “backwards compatibility”.

Email to all:

“Due to budget constraints, resources will shift from $oldThingy to $newThingy. As a result, $oldThingy’s availability can no longer be maintained at the previous level.”

Then randomly kill oldThingy for more and more hours each day.

location /old_api {
  redirect /new_api
}

(can’t be bothered to check the syntax).

“The other 98% of the codebase.”

I didn’t know what XCode was, so I read the first three words of its Wikipedia article.

Xcode is Apple’s

And suddenly, all surprise vanished.
