Security fix for RegExps that should not be evaluated (regexp DDOS)
v4.8.0
Support for numeric separators (million = 1_000_000) was added.
Assigning properties to a class is now assumed to be pure.
Fixed bug where yield wasn't considered a valid property key in generators.
v4.7.0
A bug was fixed where an arrow function would have the wrong size
arguments object is now considered safe to retrieve properties from (useful for length, or 0) even when pure_getters is not set.
Fixed erroneous const declarations without value (which is invalid) in some corner cases when using collapse_vars.
v4.6.13
Fixed issue where ES5 object properties were being turned into ES6 object properties due to more lax unicode rules.
Fixed parsing of BigInt with lowercase e in them.
v4.6.12
Fixed subtree comparison code, making it see that [1,[2, 3]] is different from [1, 2, [3]]
Printing of unicode identifiers has been improved
v4.6.11
Read unused classes' properties and method keys, to figure out if they use other variables.
Prevent inlining into block scopes when there are name collisions
Functions are no longer inlined into parameter defaults, because they live in their own special scope.
When inlining identity functions, take into account the fact they may be used to drop this in function calls.
Nullish coalescing operator (x ?? y), plus basic optimization for it.
Template literals in binary expressions such as + have been further optimized
v4.6.10
Do not use reduce_vars when classes are present
v4.6.9
Check if block scopes actually exist in blocks
v4.6.8
Take into account "executed bits" of classes like static properties or computed keys, when checking if a class evaluation might throw or have side effects.
v4.6.7
Some new performance gains through a AST_Node.size() method which measures a node's source code length without printing it to a string first.
v3.4.4 release bumps resolve-url-loader to a version for which npm audit does not report a vulnerability. Note that this vulnerability did not affect Create React App projects, so this change is only necessary to satisfy auditing tools.
