# Changelog
## 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
- `/*#__INLINE__*/` annotation fixed for arrow functions with non-block bodies.
- Functional tests have been added, using [this repository](https://github.com/terser/terser-functional-tests).
- A memory leak, where the entire AST lives on after compression, has been plugged.
## v4.4.2
- Fixed a problem with inlining identity functions
## v4.4.1
*note:* This introduced a feature, therefore it should have been a minor release.
- Fixed a crash when `unsafe` was enabled.
- An issue has been fixed where `let` statements might be collapsed out of their scope.
- Some error messages have been improved by adding quotes around variable names.
## v4.4.0
- Added `/*#__INLINE__*/` and `/*#__NOINLINE__*/` annotations for calls. If a call has one of these, it either forces or forbids inlining.
## v4.3.11
- Fixed a problem where `window` was considered safe to access, even though there are situations where it isn't (Node.js, workers...)
- Fixed an error where `++` and `--` were considered side-effect free
- `Number(x)` now needs both `unsafe` and and `unsafe_math` to be compressed into `+x` because `x` might be a `BigInt`
- `keep_fnames` now correctly supports regexes when the function is in a variable declaration
## v4.3.10
- Fixed syntax error when repeated semicolons were encountered in classes
- Fixed invalid output caused by the creation of empty sequences internally
- Scopes are now updated when scopes are inlined into them
## v4.3.9
- Fixed issue with mangle's `keep_fnames` option, introduced when adding code to keep variable names of anonymous functions
## v4.3.8
- Typescript typings fix
## v4.3.7
- Parsing of regex options in the CLI (which broke in v4.3.5) was fixed.
- typescript definition updates
## v4.3.6
(crash hotfix)
## v4.3.5
- Fixed an issue with DOS line endings strings separated by `\` and a new line.
- Improved fix for the output size regression related to unused references within the extends section of a class.
- Variable names of anonymous functions (eg: `const x = () => { ... }` or `var func = function () {...}`) are now preserved when keep_fnames is true.
- Fixed performance degradation introduced for large payloads in v4.2.0
## v4.3.4
- Fixed a regression where the output size was increased when unused classes were referred to in the extends clause of a class.
- Small typescript typings fixes.
- Comments with `@preserve`, `@license`, `@cc_on` as well as comments starting with `/*!` and `/**!` are now preserved by default.
## v4.3.3
- Fixed a problem where parsing template strings would mix up octal notation and a slash followed by a zero representing a null character.
- Started accepting the name `async` in destructuring arguments with default value.
- Now Terser takes into account side effects inside class `extends` clauses.
- Added parens whenever there's a comment between a return statement and the returned value, to prevent issues with ASI.
- Stopped using raw RegExp objects, since the spec is going to continue to evolve. This ensures Terser is able to process new, unknown RegExp flags and features. This is a breaking change in the AST node AST_RegExp.
## v4.3.2
- Typescript typing fix
- Ensure that functions can't be inlined, by reduce_vars, into places where they're accessing variables with the same name, but from somewhere else.
## v4.3.1
- Fixed an issue from 4.3.0 where any block scope within a for loop erroneously had its parent set to the function scopee
- Fixed an issue where compressing IIFEs with argument expansions would result in some parameters becoming undefined
- addEventListener options argument's properties are now part of the DOM properties list.
## v4.3.0
- Do not drop computed object keys with side effects
- Functions passed to other functions in calls are now wrapped in parentheses by default, which speeds up loading most modules
- Objects with computed properties are now less likely to be hoisted
- Speed and memory efficiency optimizations
- Fixed scoping issues with `try` and `switch`
## v4.2.1
- Minor refactors
- Fixed a bug similar to #369 in collapse_vars
- Functions can no longer be inlined into a place where they're going to be compared with themselves.
- reduce_funcs option is now legacy, as using reduce_vars without reduce_funcs caused some weird corner cases. As a result, it is now implied in reduce_vars and can't be turned off without turning off reduce_vars.
- Bug which would cause a random stack overflow has now been fixed.
## v4.2.0
- When the source map URL is `inline`, don't write it to a file.
- Fixed output parens when a lambda literal is the tag on a tagged template string.
- The `mangle.properties.undeclared` option was added. This enables the property mangler to mangle properties of variables which can be found in the name cache, but whose properties are not known to this Terser run.
- The v8 bug where the toString and source representations of regexes like `RegExp("\\\n")` includes an actual newline is now fixed.
- Now we're guaranteed to not have duplicate comments in the output
- Domprops updates
## v4.1.4
- Fixed a crash when inlining a function into somewhere else when it has interdependent, non-removable variables.
## v4.1.3
- Several issues with the `reduce_vars` option were fixed.
- Starting this version, we only have a dist/bundle.min.js
## v4.1.2
- The hotfix was hotfixed
## v4.1.1
- Fixed a bug where toplevel scopes were being mixed up with lambda scopes
## v4.1.0
- Internal functions were replaced by `Object.assign`, `Array.prototype.some`, `Array.prototype.find` and `Array.prototype.every`.
- A serious issue where some ESM-native code was broken was fixed.
- Performance improvements were made.
- Support for BigInt was added.
- Inline efficiency was improved. Functions are now being inlined more proactively instead of being inlined only after another Compressor pass.
## v4.0.2
(Hotfix release. Reverts unmapped segments PR [#342](https://github.com/terser/terser/pull/342), which will be put back on Terser when the upstream issue is resolved)
## v4.0.1
- Collisions between the arguments of inlined functions and names in the outer scope are now being avoided while inlining
- Unmapped segments are now preserved when compressing a file which has source maps
- Default values of functions are now correctly converted from Mozilla AST to Terser AST
- JSON ⊂ ECMAScript spec (if you don't know what this is you don't need to)
- Export AST_* classes to library users
- Fixed issue with `collapse_vars` when functions are created with the same name as a variable which already exists
- Added `MutationObserverInit` (Object with options for initialising a mutation observer) properties to the DOM property list
- Custom `Error` subclasses are now internally used instead of old-school Error inheritance hacks.
- Documentation fixes
- Performance optimizations
## v4.0.0
- **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
## v3.17.0
- More DOM properties added to --mangle-properties's DOM property list

### Annotations
Annotations in Terser are a way to tell it to treat a certain function call differently. The following annotations are available:
* `/*@__INLINE__*/` - forces a function to be inlined somewhere.
* `/*@__NOINLINE__*/` - Makes sure the called function is not inlined into the call site.
* `/*@__PURE__*/` - Marks a function call as pure. That means, it can safely be dropped.
You can use either a `@` sign at the start, or a `#`.
Here are some examples on how to use them:
```javascript
/*@__INLINE__*/
function_always_inlined_here()
/*#__NOINLINE__*/
function_cant_be_inlined_into_here()
