 # Changelog
 
+## 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.
+ - An issue with setting `--comments` to `false` in the CLI has been fixed.
+ - Fixed some issues with inlining
+ - `unsafe_symbols` compress option was added, which turns `Symbol("name")` into just `Symbol()`
+ - Brought back compress performance improvement through the `AST_Node.equivalent_to(other)` method (which was reverted in v4.6.6).
+
+## v4.6.6
+
+(hotfix release)
+
+ - Reverted code to 4.6.4 to allow for more time to investigate an issue.
+
+## v4.6.5 (REVERTED)
+
+ - Improved compress performance through using a new method to see if two nodes are equivalent, instead of printing them to a string.
+
+## v4.6.4
+
+ - The `"some"` value in the `comments` output option now preserves `@lic` and other important comments when using `//`
+ - `</script>` is now better escaped in regex, and in comments, when using the `inline_script` output option
+ - Fixed an issue when transforming `new RegExp` into `/.../` when slashes are included in the source
+ - `AST_Node.prototype.constructor` now exists, allowing for easier debugging of crashes
+ - Multiple if statements with the same consequents are now collapsed
+ - Typescript typings improvements
+ - Optimizations while looking for surrogate pairs in strings
+
+## v4.6.3
+
+ - Annotations such as `/*#__NOINLINE__*/` and `/*#__PURE__*/` may now be preserved using the `preserve_annotations` output option
+ - A TypeScript definition update for the `keep_quoted` output option.
+
+## v4.6.2
+
+ - A bug where functions were inlined into other functions with scope conflicts has been fixed.
+ - `/*#__NOINLINE__*/` annotation fixed for more use cases where inlining happens.
+
+## v4.6.1
+
+ - Fixed an issue where a class is duplicated by reduce_vars when there's a recursive reference to the class.
+
+## v4.6.0
+
+ - Fixed issues with recursive class references.
+ - BigInt evaluation has been prevented, stopping Terser from evaluating BigInts like it would do regular numbers.
+ - Class property support has been added
+
+## v4.5.1
+
+(hotfix release)
+
+ - Fixed issue where `() => ({})[something]` was not parenthesised correctly.
+
+## v4.5.0
+
+ - Inlining has been improved
+ - An issue where keep_fnames combined with functions declared through variables was causing name shadowing has been fixed
+ - You can now set the ES version through their year
+ - The output option `keep_numbers` has been added, which prevents Terser from turning `1000` into `1e3` and such
+ - Internal small optimisations and refactors
+
 ## v4.4.3
 
  - Number and BigInt parsing has been fixed
