[CTAN Announcements]

François Pantigny submitted an update to the

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).
