** ImageMagick support, if available, is automatically enabled.
It is no longer necessary to call `imagemagick-register-types'

*** `current-time-string' no longer requires that its argument's year
must be in the range 1000..9999. It now works with any year supported

*** `current-time' now returns extended-format time stamps
(HIGH LOW USEC PSEC), where the new PSEC slot specifies picoseconds.
PSEC is typically a multiple of 1000 on current machines. Other
[TRIGGERED-P HI-SECS LO-SECS USECS REPEAT-DELAY FUNCTION ARGS IDLE-DELAY PSECS].
The PSECS slot is new, and uses picosecond resolution. It can be
accessed via the new timer--psecs accessor.

*** Last-modified time stamps in undo lists now are of the form
(t HI-SECS LO-SECS USECS PSECS) instead of (t HI-SECS . LO-SECS).
