description: Elsevier publishes a dated release-notes archive for the Research Products APIs. It runs
  from 2014-12-16 to 2019-09-12 and then stops. 93 dated entries, none in the last seven years, while
  the underlying contracts (SciVal topic clusters, SUSHI COP5.1, ScienceDirect Search V2) have plainly
  moved on. Recording the recent window here means recording that the recent window is empty.

  visible only in the contracts themselves. This is the single most consequential operational gap in the
  Elsevier developer surface: an integrator has no supported way to learn that something changed.'

    all APIs with the throttling limits adjusted to minimize potential client impacts.
