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!
