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).

## 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;
• etc.

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