CHANGELOG.md
# Changelog
## v0.17.0 (29 Sep 2015)
* Additions:
- `differenceInDays`
- `getTimeSinceMidnight`
* Improvements:
- `setISOWeek` now keeps time from original date
- Reuse `getDaysInMonth` inside of `addMonths`
- Complete UMD package (for Bower)
* Bug fixes:
- Fix a lot of bugs appearing when date is modifying into other time zone
(e.g., when adding months and original date is in DST but new date is not)
- Prevent instances of Date to lose milliseconds value when passed to
`parse` in IE10
## v0.16.0 (1 Sep 2015)
