Is there a cheatsheet for OpenCV 3? what are key differences in v3?

Question

Is there a cheatsheet for OpenCV 3? what are additional features and functions in OpenCV3 that need to be considered?

Also, most important - what are the functions and modules that are no more available in OpenCV 3?

Note : I notice that there is a cheat sheet for 2.4. Is that still good for OpenCV 3 also?

Answer 1

In "Learning OpenCV 3" by Adrian Kaehler & Gary Bradsky (the library founder), the second release (2017-01-20), there's link to Cheat Sheet:

http://docs.opencv.org/3.0-last-rst/opencv_cheatsheet.pdf

..but it points to "OpenCV 2.4 Cheat Sheet (C++)". So I assume there's no official OpenCV 3.x Cheat Sheet.

For changes in the library introduced to 3.0 you can refer to this page:
