.SH DESCRIPTION
These -dev executables are made so that anyone interested can easily
help test upcoming \*(LX releases. They correspond to new formats which
have been tested by the \*(LX team for stability and usability. They are
not arbitrary development snapshots; more like release candidates and
checkpoints.
.PP
Testing by as many users as possible is desired and requested. Simply
replacing the regular engine (e.g., pdflatex) with the -dev engine name
(pdflatex-dev) in your invocations is all that should be needed. No
changes to source documents should be required.
.PP
The lualatex-dev format is built with the luahbtex engine, the Lua\*(TX
variant with HarfBuzz (https://en.wikipedia.org/wiki/HarfBuzz) supported
for glyph shaping.
.PP
The latest ltnews document present in latex-dev describes the changes
present in -dev compared to the previous official release. E.g., if the
official release has a document ltnews42.pdf, then look for ltnews43.pdf
in the -dev tree.
