There are different kinds of windows. I put in Anderson windows in my
addition that are sorta intermediate storm types -- they have tabs on
the frames to hold the sashes in but are not impact resistant for
hurricanes, etc. Those windows are really expensive but the higher end
houses over on the barrier islands tend to use them and obviate the need
for storm shutters (perhaps).
Interestingly, the fire dept says that unless there is life in danger
they will pretty much watch a "hurricane" house burn, and keep those
nearby hosed down, as with the hurricane windows, metal roofs, and
Hardie siding they cannot break into walls or roofs or windows to put
water on a fire. Saw some article somewhere a day or two ago of someone
saying they were astounded that the houses on the shore up in NJ did not
have shutters on the windows, that might be the reason.
As far as strapping -- in Houston (and maybe the rest of TX along the
coast) the strapping had to run from the sill up over to the roof for
single story houses, not sure about 2 story but there are strap
requirements there too. Here along the coast in SC the straps just need
to tie the walls to the sill, run up a bit on the wall studs.

It's interesting that the main change was in strapping and things as
simple as nailing schedules and decking clips.
There are also issues with end gables and their construction as well,
but I don't recall the exact details.
The changes are ongoing, and have been modified almost constantly
since the mid 90s.
The one thing I always thought was peculiar was all of the attention
to the roof decking and trusses, yet they continue to use aluminum
framed single glazed windows. When we built our last house down here
we wanted double pane windows for noise and energy efficiency, and the
builder wouldn't do it. Strange.

The changes in building code are interesting to me. 30+ years ago, when I put up roof
trusses, I used the 1" or 3/4" steel strapping that came with the lumber to cut into
18" strips that I used to tie each end of the truss down to the wall. It is interesting
to me in that the code became essentially the same thing except that the code is mild steel,
where I was using tempered steel. I saw it as recycling waste into making the building
safer. Back then we didn't have truss nails so I used roofing nails to fasten the straps to
the wood so that the force was shear force on the nail.
We are fortunate to live in a newer area, in which all of the hurricane codes
resulting from Andrew were in place. As a result, when the three hurricanes
passed through in the early 2000s, the interruption, if any, was minimal. It's
amazing how little the changes were in residential construction and how much
difference they made in the integrity of the homes built with the revised
hurricane codes.
