Any new classes/functions in Lr5(b)?

This command line is handy for finding classes and namespaces:

cd Lightroom-program-directory

strings * | grep '^Lr' | sort -u

I found one new namespace, which looks intended for running LR slideshows from a custom user interface:

LrController:

{--table: 1
previousPhoto = function: 00000000145D3330,
nextPhoto = function: 00000000145D32F0,
stopSlideshow = function: 00000000145D33B0,
triggerCapture = function: 00000000145D33F0,
showGrid = function: 00000000145D3270,
startSlideshow = function: 00000000145D3370,
showLoupe = function: 00000000145D3230,
showBezel = function: 00000000148EC500}
