+
+
+v2.1.0 (2014-08-25)
+-------------------
+
+Large code refactor with better OOP, better code reuse, and more comments.
+**No more reliance on jQuery UI** for event dragging, resizing, or anything else.
+
+Significant changes to HTML/CSS skeleton:
+- Leverages tables for liquid rendering of days and events. No costly manual repositioning ([809])
+- **Backwards-incompatibilities**:
+	- **Many classNames have changed. Custom CSS will likely need to be adjusted.**
+	- IE7 definitely not supported anymore
+	- In `eventRender` callback, `element` will not be attached to DOM yet
+	- Events are styled to be one line by default ([1992]). Can be undone through custom CSS,
+	  but not recommended (might get gaps [like this][111] in certain situations).
+
+A "more..." link when there are too many events on a day ([304]). Works with month and basic views
+as well as the all-day section of the agenda views. New options:
+- `eventLimit`. a number or `true`
+- `eventLimitClick`. the `"popover`" value will reveal all events in a raised panel (the default)
+- `eventLimitText`
+- `dayPopoverFormat`
+
+Changes related to height and scrollbars:
+- `aspectRatio`/`height`/`contentHeight` values will be honored *no matter what*
+	- If too many events causing too much vertical space, scrollbars will be used ([728]).
+	  This is default behavior for month view (**backwards-incompatibility**)
+	- If too few slots in agenda view, view will stretch to be the correct height ([2196])
+- `'auto'` value for `height`/`contentHeight` options. If content is too tall, the view will
+  vertically stretch to accomodate and no scrollbars will be used ([521]).
+- Tall weeks in month view will borrow height from other weeks ([243])
+- Automatically scroll the view then dragging/resizing an event ([1025], [2078])
+- New `fixedWeekCount` option to determines the number of weeks in month view
+	- Supersedes `weekMode` (**deprecated**). Instead, use a combination of `fixedWeekCount` and
+	  one of the height options, possibly with an `'auto'` value
+
+Much nicer, glitch-free rendering of calendar *for printers* ([35]). Things you might not expect:
+- Buttons will become hidden
+- Agenda views display a flat list of events where the time slots would be
+
+Other issues resolved along the way:
+- Space on right side of agenda events configurable through CSS ([204])
+- Problem with window resize ([259])
+- Events sorting stays consistent across weeks ([510])
+- Agenda's columns misaligned on wide screens ([511])
+- Run `selectHelper` through `eventRender` callbacks ([629])
+- Keyboard access, tabbing ([637])
+- Run resizing events through `eventRender` ([714])
+- Resize an event to a different day in agenda views ([736])
+- Allow selection across days in agenda views ([778])
+- Mouseenter delegated event not working on event elements ([936])
+- Agenda event dragging, snapping to different columns is erratic ([1101])
+- Android browser cuts off Day view at 8 PM with no scroll bar ([1203])
+- Don't fire `eventMouseover`/`eventMouseout` while dragging/resizing ([1297])
+- Customize the resize handle text ("=") ([1326])
+- If agenda event is too short, don't overwrite `.fc-event-time` ([1700])
+- Zooming calendar causes events to misalign ([1996])
+- Event destroy callback on event removal ([2017])
+- Agenda views, when RTL, should have axis on right ([2132])
+- Make header buttons more accessibile ([2151])
+- daySelectionMousedown should interpret OSX ctrl+click as a right mouse click ([2169])
+- Best way to display time text on multi-day events *with times* ([2172])
+- Eliminate table use for header layout ([2186])
+- Event delegation used for event-related callbacks (like `eventClick`). Speedier.

+
+
+v1.5 (2011-03-19)
+-----------------
+
+- slicker default styling for buttons
+- reworked a lot of the calendar's HTML and accompanying CSS (solves [327] and [395])
+- more printer-friendly (fullcalendar-print.css)
+- fullcalendar now inherits styles from jquery-ui themes differently.
+  styles for buttons are distinct from styles for calendar cells.
+  (solves [299])
+- can now color events through FullCalendar options and Event-Object properties ([117])
+  THIS IS NOW THE PREFERRED METHOD OF COLORING EVENTS (as opposed to using className and CSS)
+	- FullCalendar options:
+		- eventColor (changes both background and border)
+		- eventBackgroundColor
+		- eventBorderColor
+		- eventTextColor
+	- Event-Object options:
+		- color (changes both background and border)
+		- backgroundColor
+		- borderColor
+		- textColor
+- can now specify an event source as an *object* with a `url` property (json feed) or
+  an `events` property (function or array) with additional properties that will
+  be applied to the entire event source:
+	- color (changes both background and border)
+	- backgroudColor
+	- borderColor
+	- textColor
+	- className
+	- editable
+	- allDayDefault
+	- ignoreTimezone
+	- startParam (for a feed)
+	- endParam   (for a feed)
+	- ANY OF THE JQUERY $.ajax OPTIONS
+	  allows for easily changing from GET to POST and sending additional parameters ([386])
+	  allows for easily attaching ajax handlers such as `error` ([754])
+	  allows for turning caching on ([355])
+- Google Calendar feeds are now specified differently:
+	- specify a simple string of your feed's URL
+	- specify an *object* with a `url` property of your feed's URL.
+	  you can include any of the new Event-Source options in this object.
+	- the old `$.fullCalendar.gcalFeed` method still works
+- no more IE7 SSL popup ([504])
+- remove `cacheParam` - use json event source `cache` option instead
+- latest jquery/jquery-ui

+## Reporting Bugs
+
+Each bug report MUST have a [JSFiddle/JSBin] recreation before any work can begin. [further instructions &raquo;](http://fullcalendar.io/wiki/Reporting-Bugs/)
+
+
+## Requesting Features
+
+Please search the [Issue Tracker] to see if your feature has already been requested, and if so, subscribe to it. Otherwise, read these [further instructions &raquo;](http://fullcalendar.io/wiki/Requesting-Features/)
+
+
+## Contributing Features
+
+The FullCalendar project welcomes [Pull Requests][Using Pull Requests] for new features, but because there are so many feature requests (over 100), and because every new feature requires refinement and maintenance, each PR will be prioritized against the project's other demands and might take a while to make it to an official release.
+
+Furthermore, each new feature should be designed as robustly as possible and be useful beyond the immediate usecase it was initially designed for. Feel free to start a ticket discussing the feature's specs before coding.
+
+
+## Contributing Bugfixes
+
+In the description of your [Pull Request][Using Pull Requests], please include recreation steps for the bug as well as a [JSFiddle/JSBin] demo. Communicating the buggy behavior is a requirement before a merge can happen.
+
+
+## Contributing Languages
+
+Please edit the original files in the `lang/` directory. DO NOT edit anything in the `dist/` directory. The build system will responsible for merging FullCalendar's `lang/` data with the [MomentJS locale data].
+
+
+## Other Ways to Contribute
+
+[Read about other ways to contribute &raquo;](http://fullcalendar.io/wiki/Contributing/)
+
+
+## Getting Set Up
+
+You will need [Git][git], [Node][node], and NPM installed. For clarification, please view the [jQuery readme][jq-readme], which requires a similar setup.
+
+Also, you will need the [grunt-cli][grunt-cli] and [bower][bower] packages installed globally (`-g`) on your system:
+
+	npm install -g grunt-cli bower
+
+Then, clone FullCalendar's git repo:
+
+	git clone git://github.com/arshaw/fullcalendar.git
+
+Enter the directory and install FullCalendar's development dependencies:
+
+	cd fullcalendar
+	./build/init.sh
+
+
+## What to edit
+
+When modifying files, please do not edit the generated or minified files in the `dist/` directory. Please edit the original `src/` files.
+
+
+## Development Workflow
+
+After you make code changes, you'll want to compile the JS/CSS so that it can be previewed from the tests and demos. You can either manually rebuild each time you make a change:
+
+	grunt dev
+
+Or, you can run a script that automatically rebuilds whenever you save a source file:
+
+	./build/watch.sh
+
+When you are finished, run the following command to write the distributable files into the `./dist/` directory:
+
+	grunt
+
+If you want to clean up the generated files, run:
+
+	grunt clean
+
+

+
+```js
+if (true) {
+}
+else { // please put else, else if, and catch on a separate line
+}
+
+// please write one-line array literals with a one-space padding inside
+var a = [ 1, 2, 3 ];
+
+// please write one-line object literals with a one-space padding inside

-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-        GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-          NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.

+### 2.8.1
+
+* bugfix [#1813](https://github.com/moment/moment/issues/1813): fix moment().lang([key]) incompatibility
+
+### 2.8.0 [See changelog](https://gist.github.com/ichernev/ac3899324a5fa6c8c9b4)
+
+* incompatible changes
+    * [#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.
+
+* deprecations (old behavior will be dropped in 3.0)
+    * [#1761](https://github.com/moment/moment/issues/1761) `lang` is renamed to `locale`, `langData` -> `localeData`. Also there is now `defineLocale` that should be used when creating new locales
+    * [#1763](https://github.com/moment/moment/issues/1763) `add(unit, value)` and `subtract(unit, value)` are now deprecated. Use `add(value, unit)` and `subtract(value, unit)` instead.
+    * [#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.
+
+* new locales
+    * [#1789](https://github.com/moment/moment/issues/1789) Tibetan (bo)
+    * [#1786](https://github.com/moment/moment/issues/1786) Africaans (af)
+    * [#1778](https://github.com/moment/moment/issues/1778) Burmese (my)
+    * [#1727](https://github.com/moment/moment/issues/1727) Belarusian (be)
+

+    * [#1577](https://github.com/moment/moment/issues/1577), [#1604](https://github.com/moment/moment/issues/1604) put Date parsing in moment.createFromInputFallback so it can be properly deprecated and controlled in the future
+    * [#1545](https://github.com/moment/moment/issues/1545) extract two-digit year parsing in moment.parseTwoDigitYear, so it can be overwritten
+    * [#1590](https://github.com/moment/moment/issues/1590) (see [#1574](https://github.com/moment/moment/issues/1574)) set AMD global before module definition to better support non AMD module dependencies used in AMD environment

+
+### 1.7.2 [See discussion](https://github.com/timrwood/moment/issues/456)
+
+Bugfixes
+
+### 1.7.1 [See discussion](https://github.com/timrwood/moment/issues/384)
+
+Bugfixes
+

+
+Added `moment.fn.endOf()` and `moment.fn.startOf()`.
+
+Added validation via `moment.fn.isValid()`.
+

+
+Added instance specific languages.
+
+Added two letter weekday abbreviations with the formatting token `dd`.
+
+Various language updates.
+
+Various bugfixes.
+
+### 1.6.0 [See discussion](https://github.com/timrwood/moment/pull/268)
+
+Added Durations.
+
+Revamped parser to support parsing non-separated strings (YYYYMMDD vs YYYY-MM-DD).

+
+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.

+### 0.6.0
+
+Added _date.lang() support.
+Added support for passing multiple formats to try to parse a date. _date("07-10-1986", ["MM-DD-YYYY", "YYYY-MM-DD"]);
+Made parse from string and single format 25% faster.
+
+### 0.5.2

+
+### 0.3.0
+
+Switched to the Underscore methodology of not mucking with the native objects' prototypes.
+Made chaining possible.
+
+### 0.2.1
+
+Changed date names to be a more pseudo standardized 'dddd, MMMM Do YYYY, h:mm:ss a'.
+Added `Date.prototype` functions `add`, `subtract`, `isdst`, and `isleapyear`.

+[![Coverage Status](https://coveralls.io/repos/moment/moment/badge.svg?branch=master)](https://coveralls.io/r/moment/moment?branch=master)
+
+A lightweight JavaScript date library for parsing, validating, manipulating, and formatting dates.
+
+## [Documentation](http://momentjs.com/docs/)
+
+## Port to ES6 (version 2.10.0)
+
+Moment 2.10.0 does not bring any new features, but the code is now written in
+es6 modules and placed inside `src/`. Previously `moment.js`, `locale/*.js` and
+`test/moment/*.js`, `test/locale/*.js` contained the source of the project. Now
+the source is in `src/`, temporary build (es5) files are placed under
+`build/umd/` (for running tests during development), and the `moment.js` and
+`locale/*.js` files are updated only on release.
+
+If you want to use a particular revision of the code, make sure to run
+`grunt transpile update-index`, so `moment.js` and `locales/*.js` are synced
+with `src/*`. We might place that in a commit hook in the future.
+
+## Upgrading to 2.0.0
+
+There are a number of small backwards incompatible changes with version 2.0.0. [See the full descriptions here](https://gist.github.com/timrwood/e72f2eef320ed9e37c51#backwards-incompatible-changes)
+
+ * Changed language ordinal method to return the number + ordinal instead of just the ordinal.
+
+ * Changed two digit year parsing cutoff to match strptime.
+
+ * Removed `moment#sod` and `moment#eod` in favor of `moment#startOf` and `moment#endOf`.
+
+ * Removed `moment.humanizeDuration()` in favor of `moment.duration().humanize()`.
+
+ * Removed the lang data objects from the top level namespace.
+
+ * Duplicate `Date` passed to `moment()` instead of referencing it.
