We have tested an experimental version +for a few months and not encountered issues. + +(2) If you use Lua 5.3 you should be aware of a few changes in the language and +its implementation. Numbers are now either integers or floats but are cast +automatically. + +(3) In some cases (e.g. string.format) there is a more strict check. A float always +has a decimal appended when serialized, so 1 becomes 1.0 as string. + +(4) We keep supporting the bit32 library on top of the new bit operators. Be aware +of the fact that currently LuajitTeX does not have these operators. + +(5) Performance of LuaTeX with Lua 5.3 can be slightly better than with 5.2 but this +really depends on your usage of Lua. In practice there should be no slowdown. + +(6) We are aware of possible substantial slowdown of string.format depending on the +platform and compiler. This depends on Lua too and will be resolved in due time. + +(7) If you want to test with Lua 5.3 then have to build LuaTeX with --lua53. Because +ConTeXt will switch to 5.3 after this release there will be binaries available at the +ConTeXt garden. + +(8) The 2018 TeXlive distribution will ship with LuaTeX using Lua 5.2 but there will +likely be an additional binary LuaTeX53 available. + +(9) From 2019 TeXlive will ship with LuaTeX and Lua 5.3 as default. We provide --lua52 +as build flag for a while. By then we might be looking at Lua 5.4 already. + +(10) There are the usual patches and cleanups and a few small additions (mentioned +in the manual) but there have been no fundamental changes in the API (apart from +removing depricated and undocumented functionality). + -This file is in the public domain. ============================================================== LuaTeX Release 1.0.4 was released 2017033109 -- GitLab
