Intro TC39 の Stage 2 と Stage 3 の間に、新たに Stage 2.7 が追加された。 これはなんだろうと思った人が、検索で辿りつけるよう、その経緯と目的をまとめる。 TC39 Stages TC39 は、 ECMAScript (つまりまあ JS) の新機能を議論する Task Group だ。 ここでは、比較的自由に新機能の提案がなされ、定期的に行われるミーティングでの議論や、実装からのフィードバックを経て、 Stage が上がっていく仕組みをとっている。 旧来の Stage は 0~4 まであった。ざっくり言うと以下のようなものだ。

GitHub - tc39/proposal-signals: A proposal to add signals to JavaScript.
Stage 1 (explanation) Authors: Rob Eisenberg and Daniel Ehrenberg This document describes an early common direction for signals in JavaScript, similar to the Promises/A+ effort which preceded the Promises standardized by TC39 in ES2015. Try it for yourself, using a polyfill. Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a

GitHub - tc39/test262-parser-tests: tests designed for ECMA-262 parsers
This repository contains tests designed for parsers. There are three directories of tests: pass/, which contains syntactically valid ECMAScript programs, early/, which contains programs which match the grammar of ECMAScript but which trigger early errors, and fail/, which contains files which do not match the grammar of ECMAScript. A fourth directory, pass-explicit/, contains alternative versions
Unique identifiers for Japanese calendar eras · Issue #526 · tc39/proposal-temporal

That requires that these identifiers are unique. However, that seems not to be the case as there are several eras written with different kanji but with the
