Luatex 1.08.0 announcement

============================================================== LuaTeX 1.08 2018-08-28 ============================================================== (1) This release is a prelude to 1.10, the next stable iteration of LuaTeX after version 1.00. (2) Lua 5.3 is now considered to be default and we might use 5.4 in version 1.10. There are no real functional changed expected. You still need to rename the binary for 5.3! (3) Binary mode is no longer available in MPlib but it is still available in stand alone MetaPost. This simplifies compilation and reduces dependencies. (4) The dependency on Poppler for pdf image inclusion has been removed. We now use a small dedicated library written by Pawel Jakowski. We no longer need c++ compilers. We're in the process of making it behave well on all platforms. It has been tested on intel platforms. (5) We know that there can be some (alignment) issues with the arm platform but these are looked into. Therefore, later this year we will release 1.09. Version 1.10 is planned for TeXlive. We hope that ffi works ok on intel and arm platforms at that point. (6) There have been some extensions to the Lua libraries and some callbacks have been added. Also, a few new primitives have been introduced. The documentation mentions the stable extensions. (7) There are the usual bug fixes and cleanups but there have been no real fundamental changes in the API. The LuaTeX team

Not searching the font cache
by Jouke Witteveen 08 Jan '19

Hi, I ran into an inconvenience with lualatex and would like some help debugging it. Consider the following .tex file: ---- documentclass{article} \usepackage{bbm} \begin{document} $\mathbbm{1}$ \end{document} ---- When compiling with pdflatex, the font file for the bbm font is created in the local cache (~/.texlive/texmf-var/fonts) only if it does not exist. When the font exists in the cache, it is used without warning. When compiling with lualatex, the font file is created every time. When the font exists, this results in a simple warning ("mktexpk: [...] already exists."). Trying to create the fonts slows down compilation noticeably. How do I go about debugging this? The fact that pdflatex has no problems suggests that this is not an issue with my texmf.cnf, right? Regards, - Jouke
