## 6.0.0

### Enhancements
- @wenq added `contour.moments` method.
- @andreasgal added `matrix.substract` method.
- @jainanshul added `matrix.mean` method.
- @idubinskiy restored `contour.points` method.
- @danschultzer updated node-pre-gyp to fix load of node-opencv in electron runtime.
- @andreasgal made `matrix.getData` work with RGB images.
- @Evilcat325 added `matrix.MatchTemplateByMatrix` method.
- @danschultzer added code coverage.

### Bug fixes
- @dominikdolancic fixed image load issue in `matrix.matchTemplate()`.
- @AwooOOoo fixed `type_info` errors in Visual Studio with std namespace pollution.
- @mvines fixed issue that prevented `AsyncSaveWorker` from using de-allocated memory.
- @mcwhittemore fixed dissimilarity example image load.
- @saoron fixed dead index.html documentup source.
- @andreasgal fixed an issue with `matrix.crop` (and potentially others), where `matrix.getData` ends up returning less than full matrix.
- @danschultzer fixed `examples/test.js` channel issue, and problematic Vec3b casting (instead of Vec3f) in `matrix.set`.

### Backwards incompatible changes
- @dxprog changed readImage to load image with `CV_LOAD_IMAGE_UNCHANGED` instead of `CV_LOAD_IMAGE_COLOR`. The latter returned the image as 3-channel.
- @danschultzer changed `VideoCapture.close` to `VideoCapture.release`.

Thanks to all, also a massive thanks to @danschultzer for helping get the open
tickets and PR's under control.

## 5.0.0 (Feb 9 2016)

- @mvines and @svogl started working on OpenCV 3.x support.
- @sirotenko added a getFrameCount method
- @vaceta implemented getFrameAt
- @jainanshul improved some methods
- @cascade256 improved the windows build

Plus fixes from @banterability, @punnerud, @vargad  etc. Thanks all.

## 4.0.0

I've been super slow releasing this one, and there's a ton of new stuff.

Importantly, @keeganbrown managed to upgrade nan to 2.0.9 so this should
work with newer versions of node.

Also a ton of new bindings from @jainanshul

Thanks to the many contributors I haven't named too.

## 3.2.0

Bugfixes from @mvines and @dropfen. Thanks!

### 3.1.0
Many bugfixes from @queuecumber, @emanuelandrada, @thomashoffmann1979,
@paulmorrishill, @zankich, @morganrallen and @AVVS.

### 3.0.0

You wait ages for a release, and 2 come along at once...

This one is awesome. It adds prebuilt binaries, so you don't need
to build opencv for the common platforms.

Many many thanks to @edgarsilva for awesome work here, and
http://hybridgroup.com/ for hosting the binaries


### 2.0.0

- Support for node 0.12
- Camera Calibration Functions from @queuecumber
- Fix for Nan 1.5.1 from @IMGNRY
- More build fixes from @scanlime
- Matrix crop prototype from @dbpieter
- Many fixes from @madshall

Thanks to everyone that contributed!


### 1.0.0

Ok, let's do a proper semver release :)

The big news in this release is that thanks to some amazing work by
@kaosat-dev, node-opencv now works with node 0.11.

There's also some general tidying up, including the examples by marcbachmann

Thanks all!
