Ecma TC39 (ECMAScript) has formally now a new Task Group (TG2)
In the March 2019 New York TC39 meeting TC39 has been slightly reorganized.
In TC39 the following formal reorganization has taken place, which has de-facto no effect on how the work has been done so far:
Ecma TC39 has two task groups:
TC39-TG1 — General ECMAScript Language (basically the old TC39 RFTG unchanged…)
TC39-TG2 — ECMAScript Internationalization API Specification (basically the old ECMA-402 Ad-Hoc Group…)
