François Pantigny submitted an update to the
nicematrix
package.
Version: 6.16
License: lppl1.3
Summary description: Improve the typesetting of mathematical matrices with PGF
Announcement text:

It's now possible to put any LaTeX extensible delimiter (\lgroup, \langle, etc.) in the preamble of an environment with preamble (such as {NiceArray}) by prefixing them by \left and \right. New key 'code' for the command \SubMatrix in the \CodeAfter (useful to insert Tikz instructions).

The package’s Catalogue entry can be viewed at https://ctan.org/pkg/nicematrix The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/nicematrix/

Thanks for the upload. For the CTAN Team Petra Rübe-Pugliese

## nicematrix – Improve the typesetting of mathematical matrices with PGF

This package is based on the package array. It creates PGF/TikZ nodes under the cells of the array and uses these nodes to provide functionalities to construct tabulars, arrays and matrices.

Among the features :

- continuous dotted lines for the mathematical matrices;
- exterior rows and columns (so-called border matrices);
- control of the width of the columns;
- tools to color rows and columns with a good PDF result;
- blocks of cells;
- tabular notes;
- etc.

The package requires and loads
l3keys2e,
array,
amsmath,
pgfcore,
and the module `shapes` of
PGF.
