Changelog: swc v1.2.6

Bugfixes

catch parameter in regenerator (#854)

While porting regenerator, I forgot handling catch parameters. The bug was that swc does not touch e in the code below.

function throwingFn() {

throw "Error";

}

function* gen() {

try {

yield throwingFn();

} catch (e) {

yield e;

}

}

console.log(gen().next());

It's now fixed and works correctly.

New features

es2020 output (#847)

Optional chaining and nullish coalescing are enabled by default, and if you want to emit those as-is, you can now specify target: "es2020".
