Changelog

Sourced from terser's changelog.

Changelog

v5.16.7

• Become less conservative with analyzing function definitions for reduce_vars
• Parse import.meta as a real AST node and not an object.property

v5.16.5

• Correctly handle AST transform functions that mutate children arrays
• Don't mutate the options object passed to Terser (#1342)
• Do not treat BigInt like a number

v5.16.4

• Keep (defaultArg = undefined) => ..., because default args don't count for function length
• Prevent inlining variables into ?. optional chains
• Avoid removing unused arguments while transforming
• Optimize iterating AST node lists
• Make sure catch and finally aren't children of try in the AST
• Use modern unicode property escapes (\p{...}) to parse identifiers when available

v5.16.3

• Ensure function definitions, don't assume the values of variables defined after them.

v5.16.2

• Fix sourcemaps with non-ascii characters (#1318)
• Support string module name and export * as (#1336)
• Do not move let out of for initializers, as it can change scoping

• Knowledge of more native object properties (#1330)
• Got rid of Travis (#1323)
• Added semi-secret asObject sourcemap option to typescript defs (#1321)

v5.16.1

• Properly handle references in destructurings (const { [reference]: val } = ...)
• Allow parsing of .#privatefield in nested classes
• Do not evaluate operations that return large strings if that would make the output code larger
• Make collapse_vars handle block scope correctly
• Internal improvements: Typos (#1311), more tests, small-scale refactoring

v5.16.0

• Disallow private fields in object bodies (#1011)
• Parse #privatefield in object (#1279)
• Compress #privatefield in object
