It should be preferred instead of Data:getPointer because the latter uses lightuserdata which can't store more all possible memory addresses on some new arm64 architectures, when LuaJIT is used.
Any attempt to call a method on the object after it has been released will result in an error. Object:release() returns true if it was successful, or false if not (if it has already been released previously).

Currently exposed formats are rgba8 and rgba16 (normalized), and rgba16f and rgba32f (floating-point). Some systems, especially mobile ones, won't support every format when creating a love.graphics Image. Use love.graphics.getRawImageFormats to check for support.
love.image.newImageData now takes an optional format parameter as its third argument when creating an empty sized ImageData. It defaults to rgba8.
16-bit PNGs, .hdr images, and floating-point OpenEXR images can now be loaded via love.image.newImageData and love.graphics.newImage.

Note that ImageData:mapPixel (with its optional sub-rectangle parameters) is often many times faster than a loop of ImageData:setPixel and/or getPixel, for anything more than a few pixels.
