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 artifact, we provide the corresponding Docker container, that can be pulled with:
docker pull ghcr.io/massimo-nocentini/lua.docker:5.5.0
It enhances the previous container for version 5.4.8:
docker pull ghcr.io/massimo-nocentini/lua.docker:5.4.8
respectively.
