aside from bugs?  2.53 has some new ones which I noticed but haven't
gotten around to studying - I only got to that early this week.

The usual point about incompatibility is that quoting has changed.
Indirectly that also affects the use of macros within macros - some
combinations were declared illegal in 2.5x.  I note that 2.5x detects a
few of the places where incompatibilties were introduced but generally
not.  I've modified most of my scripts so they'll work (barring new bugs
as noted) with either version, but retain compatibilty with 2.13 because
2.5x does not work with "older" shells.  Reading the bug reports, it
appears that 2.5x is tested well only using bash.
