This was a sad consequence of people paying too little attention to
alpha and beta versions. Most issues that appeared in that long
sequence of release candidates were already present in the alpha
and/or beta versions, but nobody cared to complain (probably because
they did not care to try those versions) before the final version.

It would be very helpful if people really tried this beta version...

BTW, these are the main changes from alpha to beta:

* 'dumpint' and co. replaced by 'string.pack'/'string.unpack'
* new functions 'lua_geti'/'lua_seti'
* 'ipairs' stops at first 'nil'
* 'lua_Ctx' renamed to 'lua_Kcontext'
* %U gets a long (instead of int)
* deprecated 'luaL_checkint'/'luaL_optint'/'luaL_checklong'/'luaL_optlong'
* 'luaL_getmetafield' returns field type
* 'table.copy' -> 'table.move' (plus change in order of parameters)
* 'debug.Csize' removed (subsumed by 'string.pack')
* 'lua_strtonum' -> 'lua_stringtonum'
* change in handling of non-string error messages in lua.c
* ANSI mode turns off 64 bits (as 'long long' is not ANSI)
