 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.

+\item {\tt alty}  is new as of version 1.611, and applies only when math mode uses Charter alphabets. It causes math italic y to be rendered using a rounder shape that is less problematic than the default shape because it lacks the long tail of the XCharter Italic {\usefont{T1}{XCharter-TLF}{m}{it}y}.
 \item {\tt noxchvw} (or {\tt noXchvw} is new as of version 1.54, and applies only when math mode uses Charter alphabets. It causes math italic v and w to be rendered using Charter italic glyphs. Use this only if you don't care if math italic v is hard to distinguish from Greek \verb|\nu|.

 \item {\tt cochineal}  loads different versions of math italic and bold math italic based on \textsf{cochineal} rather than \textsf{Times}---the {\tt varg} and {\tt varvw} options are disabled in this case. There are two additional options specific to {\tt cochineal}.
