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

- (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

- 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
  but this should normally go unnoticed

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

\hjcodes is
  possible (but of course goes ahead of hyphenation which is delayed till
parbuilding or

- 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:
doesn't work. It will be fixed in the next release.
