Lua 5.5.0 is out!

According to the official announcement, the following main changes are introduced:

declarations for global variables
named vararg tables
for-loop variables are read only
floats are printed in decimal with enough digits to be read back correctly.
more levels for constructors
table.create
utf8.offset returns also final position of character
external strings (that use memory not managed by Lua)
new functions luaL_openselectedlibs and luaL_makeseed
major garbage collections done incrementally
more compact arrays (large arrays use about 60% less memory)
lua.c loads readline dynamically
static (fixed) binaries (when loading a binary chunk in memory, Lua can reuse its original memory in some of the internal structures)
dump and undump reuse all strings
auxiliary buffer reuses buffer when it creates final string

Containers

As companion artifacts, we provide the corresponding alpine-based containers.
