I have just uploaded the archives for a new luatex release, 0.75.0.

Most noticeable changes:

* New expandable primitive \Uchar.

* Metapost 1.790.

* New version of lnodelib.c with speedups by Hans and Luigi.
   Also added some extra sanity checks to the Lua node field
   setting functions.

* Support 'umath' in tex.extraprimitives(), so that formats can
   make the \Umath* primitives unprefixed, now that they will be
   provided by XeTeX as well.

* Removed a bunch of deprecated primitives
   * \AlephVersion, \Alephrevision, \Alephversion, \Alephminorversion
   * \OmegaVersion, \Omegarevision, \Omegaversion, \Omegaminorversion
   * \omathcode, \odelcode, \omathchardef, \omathchar, \omathaccent,
     \odelimiter, \oradical
   * \Umathbotaccent, \Umathaccents

* Fix large file support.

* Fix Lua's loadfile().

* Removed the cidmap callbacks again (let that be done by user lua
   code after the fact).

* Removed the fatal error on fonts where num_glyphs is too high,
   as that problem is actually harmless.

* Some compilation issues under Win32 and Solaris resolved.
   NOTE: You still need an 'installed' pkg-config while building
   luatex. Either install pkg-config for your platform, or make
   sure there is a binary linking to /bin/true while configuring.
   The requirement is for the executable 'pkg-config' itself, not
   for any particular package.

* Allow math extender objects to be zero width.

* The 'epdf' library has been extended to deal with finding and
   saving embedded files (catalog:numEmbeddedFiles() and catalog:
   embeddedFile, new EmbFile object).

The archives can be downloaded from supelec as usual:
