• max-iterations option got removed, only a single pass is required to achieve the same or better result

v1.11.0

Features

• Remove debug protection (freezes the browser if you open devtools)
• Control Flow Flattening can now be deobfuscated when Transform Object Keys is enabled
• Rearrange sequences in variables: var t = (o = null, o); -> o = null; var t = o;

Bug Fixes

• Remove correct nodes in self defending code (based on references instead of the first 2 statements)

Security

Performance

Deobfuscation and readability transforms are now significantly faster

New Features

Modules can get converted to ESM:

require.r(exports);
require.d(exports, 'Counter', function () {
  return f;
});
class f {}

->

export class Counter {}

This, together with changes to some other webpack functions, will allow unpacked modules to be repacked and run instead of the original bundle:

npx webpack-cli ./webcrack-out

v1.8.0

New Features

• Merge nested else if:

if (x) { } else { if (y) {} }

->
