* [#1761](https://github.com/moment/moment/issues/1761): moments created without a language are no longer following the global language, in case it changes. Only newly created moments take the global language by default. In case you're affected by this, wait, comment on [#1797](https://github.com/moment/moment/issues/1797) and wait for a proper reimplementation
* [#1642](https://github.com/moment/moment/issues/1642): 45 days is no longer "a month" according to humanize, cutoffs for month, and year have changed. Hopefully your code does not depend on a particular answer from humanize (which it shouldn't anyway)
* [#1784](https://github.com/moment/moment/issues/1784): if you use the human readable English datetime format in a weird way (like storing them in a database) that would break when the format changes you're at risk.

* [#1759](https://github.com/moment/moment/issues/1759) rename `duration.toIsoString` to `duration.toISOString`. The js standard library and moment's `toISOString` follow that convention.
* [#1419](https://github.com/moment/moment/issues/1419), [#1468](https://github.com/moment/moment/issues/1468), [#1467](https://github.com/moment/moment/issues/1467), [#1546](https://github.com/moment/moment/issues/1546) better handling of timezone-d moments around DST

### 2.4.0
- Release Oct 27, 2013
* **Deprecate** globally exported moment, will be removed in next major
Revamped parser to support parsing non-separated strings (YYYYMMDD vs YYYY-MM-DD).
Added support for millisecond parsing and formatting tokens (S SS SSS)
Added a getter for `moment.lang()`
Various bugfixes.
There are a few things deprecated in the 1.6.0 release.
1. The format tokens `z` and `zz` (timezone abbreviations like EST CST MST etc) will no longer be supported. Due to inconsistent browser support, we are unable to consistently produce this value. See [this issue](https://github.com/timrwood/moment/issues/162) for more background.
2. The method `moment.fn.native` is deprecated in favor of `moment.fn.toDate`. There continue to be issues with Google Closure Compiler throwing errors when using `native`, even in valid instances.
3. The way to customize am/pm strings is being changed. This would only affect you if you created a custom language file. For more information, see [this issue](https://github.com/timrwood/moment/pull/222).
Added `moment.version` to get the current version.
Removed `window !== undefined` when checking if module exists to support browserify. [issue 25](https://github.com/timrwood/moment/pull/25)

### 0.5.2
- Release Jul 11, 2011

Dropped the redundant `_date.date()` in favor of `_date()`.
