 # Essential Post-v.1 Features
 
-This is a list of essential features we *know* we need but were not part of the
-Minimum Viable Product that is [v.1](V1.md). Longer-term features will be added
-in [future versions](FutureFeatures.md).
-
-## 64-bit integers
-* Provide access to efficient 64-bit arithmetic.
-* Some code will want to only use 64-bit integers when running on a 64-bit system (for performance
-  reasons) so provide a "has native 64-bit integer" query.
+This is a list of essential features that are known to be needed ASAP, but were removed from
+[v.1](V1.md) since there was not (yet) a portably-efficient polyfill via asm.js. There is a much bigger
+[list of features](FutureFeatures.md) that will be added after this list, prioritized by feedback and
+experience.
