[Hans Hagen <pragma@wxs.nl>]

Hi,

Luigi and I are currently looking into Lua 5.3 in combination with 
LuaTeX. We have an experimental setup and all seems to work well, which 
given the new number model of Lua is good news. Depending on how we 
compile the binaries we either gain some speed or in the worst case 
loose half the performance but that will be sorted out one of these days 
as we know where to look.

For most users the consequences will be minimal but for those who use a 
lot of Lua it makes sense to keep an eye on the subtle differences 
between 5.2 and 5.3 which is why I post this.

For TeXLive we don't expect the switch before 2019 (so 2018 will ship 
two binaries with the 5.2 one the official one) but for the context 
distribution we will make the switch earlier so that we can test in real 
situations.

Hans
