New luatex release, 0.87.0
From NEWS:

==================================================
This is a next step upto 0.90 and it has the following changes:

- image data is no longer stored in the format (it was fragile anyway)

- pdf backend data generated when in ini mode is no longer stored in  the
format

- (incomplete) \mag support removed from pdf backend (this functionality is
  kept in dvi mode)

- there are a couple of improvements that should make luatex run a little
bit faster
  (but of course that depends on the job at hand)

- some further pending issues / cleanup has been done (but this is not
reflected in the
  interface)

- there is a new primitive \nospace:

  \nospace=1   do now not inject glue for spaces (not even zero glue)
  \nospace=2   inject zero glue for spaces

- there are new primitives \hpack, \vpack and \tpack that are like \hbox,
\vbox and
  \vtop but they don't trigger callbacks

- we no longer keep track of older math character and delimiter definition
states,
  but this should normally go unnoticed

- from now on only ^^XX, ^^C, ^^^^XXXX and ^^^^^^XXXXXX are supported so no
funny odd
  values (three and five)

- texio.setescape(0) disables escaping to terminal (a matter of taste)

- the (current) lc codes are now saved with the (current) language when
patterns are
  loaded unless one hs used \hjcode instead of \lccode; overloading of
\hjcodes is
  possible (but of course goes ahead of hyphenation which is delayed till
parbuilding or
  packaging

- active characters can now be set with: \letcharcode123=\foo (experimental)

- there are some experimental new primitives but these will be described
when they are
  stable (currently being tested)

- there is more backend error reporting and all error messages adn warnings
(the non-tex
  ones) have been normalized

- of course there are the usual small fixes and additional setters and
getters in libraries
  (see manual)
==================================================

Last minute note:
 --synctex
doesn't work. It will be fixed in the next release.

When you use context or latex you need an updated format. The latest
version of
context can be fetched from the context garden, latex from ctan. For latex
you can contact David and Joseph as they are dealing with the update.
