release candidate LaTeX testing

Synopsis

latex-dev [options] [&format]  [ file [ more-input ]  |  [ \more-input ]

Description

These -dev executables are made so that anyone interested can easily help test upcoming L A T E X releases. They correspond to new formats which have been tested by the L A T E X team for stability and usability. They are not arbitrary development snapshots; more like release candidates and checkpoints.

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.

The lualatex-dev format is built with the luahbtex engine, the LuaT E X variant with HarfBuzz (https://en.wikipedia.org/wiki/HarfBuzz) supported for glyph shaping.

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.

Options

See tex(1) for details of command-line parsing.
