Because that's what the EABI specification requires. Yes it's a change from
the old ABI.
See:
http://infocenter.arm.com/help/topic/com.arm.doc.subset.swdev.abi/index.html
And in particular the "ABI for the ARM Architecture" document.
The change was made because having strict alignment of data types can
significantly improve performance on implementations with 64-bit and wider
data-paths within the core.
