### <sup>v0.7.0</sup>
### <sup>v0.8.0</sup>
#### Compatibility Warnings ####
* Renamed `_.zipObject` to `_.object`
* Replaced `_.drop` with `_.omit`
* Made `_.drop` alias `_.rest`
* Made `_.random` return `0` or `1` when no arguments are passed
* Moved late bind functionality from `_.bind` to [_.lateBind](http://lodash.com/docs#lateBind)
* Removed first argument falsey checks from methods
* Removed support for custom `clone`, `isEqual`, `toArray` methods from<br>
`_.clone`, `_.isEqual`, and `_.toArray`
#### Changes ####
* Added [_.invert](http://lodash.com/docs#invert), [_.pairs](http://lodash.com/docs#pairs), and [_.random](http://lodash.com/docs#random)
* Added `_.result` to the `backbone` build
* Added `exports`, `iife`, `-c`/`--stdout`, `-o`/`--output`, and `-s`/`--silent` build options
* Ensured `isPlainObject` works with objects from other documements
* Ensured `_.isEqual` compares values with circular references correctly
* Ensured `_.merge` work with four or more arguments
* Ensured `_.sortBy` performs a stable sort for `undefined` values
* Ensured `_.template` works with "interpolate" delimiters containing ternary operators
* Ensured the production build works in Node.js
* Ensured template delimiters are tokenized correctly
* Made pseudo private properties `_chain` and `_wrapped` double-underscored to avoid conflicts
* Made `minify.js` support `underscore.js`
* Reduced the size of `mobile` and `underscore` builds
* Simplified `_.isEqual` and `_.size`
* Added `-d`/`--debug`, `-m/--minify`, `minus`, `plus`, `settings`, and `template` build options
* Added `_.isPlainObject` and `_.lateBind`
* Allowed `_.sortedIndex` to accept a property name as the `callback` argument
* Ensured methods accept a `thisArg` of `null`
* Fixed the `iife` build option to accept more values
* Made `_.times` return an array of `callback` results
* Simplified `_.max`, `_.min`, and `_.reduceRight`
