 # Changelog
 
+## v1.3.3 (2017-04-07)
+
+### :bug: Bug Fix
+
+- Support electron version in a string format ([#252](https://github.com/babel/babel-preset-env/pull/252)) (@yavorsky)
+
+Adding electron as a target was an inadvertent breaking change as it no longer
+allowed string versions. We added an exception for now, even though it is
+inconsistent with other versions. Just as a note, the upcoming version 2.x will
+allow _both_ number and string versions.
+
+- Ensure const-check plugin order ([#257](https://github.com/babel/babel-preset-env/pull/257)) (@existentialism)
+
+We now force the `const-es2015-check` plugin to run first (so that it can
+correctly report issues before they get transpiled away).
+
+### :rocket: New Feature
+
+- Allow use `babel-plugin-` prefix for include and exclude ([#242](https://github.com/babel/babel-preset-env/pull/242)) (@yavorsky)
+
+The `include` and `exclude` options now allow both prefixed (`babel-plugin-transform-es2015-spread`) 
+and prefix-less (`transform-es2015-spread`) plugin names.
+
+### :memo: Documentation 
+
+- Note babel plugin prefix handling in include/exclude ([#245](https://github.com/babel/babel-preset-env/pull/245)) (@existentialism)
+- Fix README: debug option shows info in stdout. ([#236](https://github.com/babel/babel-preset-env/pull/236)) (@Gerhut)
+
+### :house: Internal
+
+- Add simple smoke-test ([#240](https://github.com/babel/babel-preset-env/pull/240)) (@existentialism)
+- Add prepublish script (@existentialism)
+
+## v1.3.2 (2017-03-30)
+
+- Fixed an issue with a broken publish
+
+## v1.3.1 (2017-03-30)
+
+- Fixed a regression with missing files due to `.npmignore`.
+
 ## v1.3.0 (2017-03-30)

 An array of plugins to always include.
 
-Valid options include any of the [babel plugins](https://github.com/babel/babel-preset-env/blob/master/data/plugin-features.js) or [built-ins](https://github.com/babel/babel-preset-env/blob/master/data/built-in-features.js), such as `transform-es2015-arrow-functions`, `map`, `set`, or `object.assign`.
+Valid options include any:
+
+- [Babel plugins](https://github.com/babel/babel-preset-env/blob/master/data/plugin-features.js) - both with (`babel-plugin-transform-es2015-spread`) and without prefix (`transform-es2015-spread`) are supported.
+
+- [Built-ins](https://github.com/babel/babel-preset-env/blob/master/data/built-in-features.js), such as `map`, `set`, or `object.assign`.
 
 This option is useful if there is a bug in a native implementation, or a combination of a non-supported feature + a supported one doesn't work.
