CTAN update: nicematrix

[CTAN Announcements]

François Pantigny submitted an update to the

                nicematrix

package.

Version number: 5.0 2020-07-15
License type: lppl1.3

Summary description: Improve the typesetting of mathematical matrices with PGF

Announcement text:
----------------------------------------------------------------------

In previous versions of nicematrix, it was mandatory, for technical reasons, to use the
letters L, C and R instead of the letters l, c, r in the preambles of the environments of
nicematrix.

In this version 5.0, one must use l, c and r.

For *compatibility* with previous versions, there is a key 'define-L-C-R' to use at
load-time : \usepackage[define-L-C-R]{nicematrix}

This version also provides a command \tabularnote to create tabular notes in
{NiceTabular}. These tabular notes are composed at the bottom of the tabular.

In this version, it's also possible to use \diagbox in a \Block.
