# Change Log

## v2.2.0
**Bugfixes:**
* Fixed bit value of `SideEffectOptions.JsxElement` to be a power of 2

**Features:**
* Added utilities: `getTokenAtPosition` and `isPositionInComment`

## v2.1.0
**Features:**
* Added typeguard `isExpression`
* Added utilities: `hasSideEffects`, `getDeclarationOfBindingElement`

## v2.0.0
**Breaking Changes:**
* Dropped compatibility with `typescript@<2.1.0`
* Removed misnamed `isNumericliteral`, use `isNumericLiteral` instead (notice the uppercase L)
* Removed `isEnumLiteralType` which will cause compile errors with typescript@2.4.0
* Refactored directory structure: all imports that referenced subdirectories (e.g. `require('tsutils/src/typeguard')` will be broken

**Features:**
* New directory structure allows imports of typeguards or utils independently, e.g. (`require('tsutils/typeguard')`)

**Bugfixes:**
* `isObjectFlagSet` now uses the correct `objectFlags` property
