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 1.739
+1. Removed unwanted ij and IJ ligatures under pdflatex.
+2. Modified definition of \mathsf in newtxmath.sty so that
+it acts as expected on uppercase Greek, both upright and slanted.
+(Thanks Alexander Malkis for alerting me to 1 and 2.)
+3. Added several newtxmath options that were missing from
+the list of math options to pass from newtx.sty.
+4. Added alternate versions of math glyphs h, hslash and hbar.
+The alternate forms have an outward pointing lower serif
+as opposed to the existing ingrown lower serif which makes the
+hard to distinguish from math b. Option alth to newtxmath or
+newtx activates the alternate forms though of course, only when
+option ebgaramond to newtxmath (or newtx) is specified.
+(Thanks Máté Wierdl.)

Changes in version 1.738
1. Documentation updated for newtx.sty usage.
2. Modified newtx.sty and newtxtext.sty to ensure that default effects of \mathsf and \mathtt are the same in both cases, and to ensure that in both, the prior loading of a sf or tt text font would result in those being used for \mathsf, \mathtt without any further interventions.
