 This package, initially based on txfonts, provides many fixes and enhancements to the txfonts package, splitting it into two separate packages---newtxtext and newtxmath, which may be run independently of one another. It provides scaling, improved metrics, and other options. In particular, newtxmath offers a libertine option which substitutes Linux Libertine (provided with TeXLive and MikTeX) italic and Greek letters for the default Times letters, providing a good match for the Libertine text font, which is heavier than Computer Modern but lighter than Times, and in my experience, looks very sharp and clear on the screen.

+Changes in version 1.653
+Following valued input from David Carlisle and Enrico Gregorio, the fd files "corrected" in 1.652 were actually corrected using a suggestion of Enrico Gregorio.

 Changes in version 1.652
 Corrected the fd files for the main text fonts. Those in version 1.651 were not functional and were released in error.
