OF 0.9.x update?

hi
your addon looks very interesting.
any plans to update it to OF 0.9.x?

ofx v0.9.8 issues

Hi there, I've found this amazing addon of yours today and I would love to use it in my projects, however, I've faced some issues while running the example.

Errors I get in the example code:

void ofApp::draw() {
 ...
"Life: " + ofToString(surfTracker.objectLifeTime, 2)
 ...
}

^ Error: No member named 'objectLifeTime'.
I can easily fix this by removing the line as it only provides information.

void ofApp::update() {
 ...
  surfTracker.detect(vidGrabber.getPixels(), CAM_W, CAM_H);
 ...
}

^Error: No matching member function for call to 'detect'.
I have managed to fix this by adding .getData() as in vidGrabber.getPixels().getData()

Errors I get in the ofxSURFTracker.cpp file from the addon:

void ofxSURFTracker::detect(ofImage &img){
  ...
    detect(img.getPixels(), inputWidth, inputHeight);
}

^ Error: No matching member function for call to 'detect'.
I have managed to fix this by adding .getData() as in img.getPixels().getData()

void ofxSURFTracker::detect(unsigned char *pix, int inputWidth, int inputHeight){
  ...
    croppedImg.setFromPixels(inputImg.getRoiPixels(), width, height);
  ...
}

^ Error: No matching member function for call to 'setFromPixels'.
Again I have managed to fix this by adding .getData() as in inputImg.getRoiPixels().getData()

ofImage ofxSURFTracker::getCroppedImage(){
  ...
	newImg.setFromPixels(croppedImg.getPixels(), croppedImg.getWidth(), croppedImg.getHeight(), OF_IMAGE_COLOR);
  ...
}

^ Error: No matching member function for call to 'setFromPixels'.
Yet again I have managed to fix this by adding .getData() as in croppedImg.getPixels().getData()

Now I can run the example and see the detection working, however, when I toggle spacebar it does not learn or match any features.

Any help would be appreciated.

P.s I run this on macOS 10.12.2 and my openFrameworks version is 0.9.8.
