*** The default settings for JIT stealth lock parameters are changed.
The default value for the user option jit-lock-stealth-time is now 16
instead of 3, and the default value of jit-lock-stealth-nice is now
0.5 instead of 0.125. The new defaults should lower the CPU usage
when Emacs is fontifying in the background.
The default value for the user option jit-lock-stealth-time is now nil
instead of 3. This setting of jit-lock-stealth-time disables stealth
fontification: on today's machines, it may be a bug in font lock
patterns if fontification otherwise noticeably degrades interactivity.
If you find movement in infrequently visited buffers sluggish (and the
major mode maintainer has no better idea), customizing
jit-lock-stealth-time to a non-nil value will let Emacs fontify
buffers in the background when it considers the system to be idle.
jit-lock-stealth-nice is now 0.5 instead of 0.125 which is supposed to
cause less load than the old defaults.

*** jit-lock can now be delayed with `jit-lock-defer-time'.
