breaking change: The variables property of all scopes has become a standard JavaScript Map as opposed to the old bespoke Dictionary object.
Typescript definitions were fixed
terser --help was fixed
The public interface was cleaned up
Fixed optimisation of Array and new Array
Added the keep_quoted=strict mode to mangle_props, which behaves more like Google Closure Compiler by mangling all unquoted property names, instead of reserving quoted property names automatically.
Fixed parent functions' parameters being shadowed in some cases
Allowed Terser to run in a situation where there are custom functions attached to Object.prototype
And more bug fixes, optimisations and internal changes

3.16.1

published 3.16.1 • 6 years ago

Changelog

Fixed issue where Terser being imported with import would cause it not to work due to the __esModule property. (PR #254 was submitted, which was nice, but since it wasn't a pure commonJS approach I decided to go with my own solution)
