Well, everybody else is struggling to move from EcmaScript 6 to EcmaScript 2015.
This of course works best when the publishers have established a rhythm (e.g., every year, as in this case, or maybe twice a year).

(Date of publication ≠ date of tool interface in use, though.)

((There is an ongoing discussion of protocol versions, protocol features, and document revisions in T2TRG right now, so I couldn’t resist.  Oh, and for ECMAScript the number counts “editions”, a term I didn’t have in active use in that discussion yet.))
