-Current version: 1.093, 2019-06-10
+Current version: 1.10, 2019-11-04

+Changes in version 1.10
+1. Math mode under option utopia to newtxmath was modified to generate pdf output complying with the PDF/A-1b standard, so that utopia now qualifies as an enhanced option to newtxmath. 
+2. Math mode Greek was modified to use mainly glyphs from the fourier package rather than modified txfonts Greek.
 
 Changes in version 1.093
 Corrected an error in the last correction to the fd file. (Thanks, Frank Mittelbach.)

 The effect of the options {\tt p,osf} is to force the default figure style in {\tt erewhon} text to be proportional oldstyle 0123456789 while using lining figures $0123456789$ in math mode. If no options are specified, tabular lining figures will be used throughout.

+\textsc{Enhanced Mathematical Options:}\\
+As of version {\tt 1.10}, the {\tt utopia} option to {\tt newtxmath} enjoys enhanced status. Most importantly, this means that you can generate pdf output satisfying the PDF/A-1b standards. It means, in addition, that the option {\tt subscriptcorrection} is available, permitting you to improve the spacing of subscripts by copying {\tt newtx-utopia-subs.tex} to your home texmf tree and modifying its entries.
