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. -Current version: 1.54 2018-04-10 +Current version: 1.55 2018-05-11 This material is subject to the LaTeX Project Public License. See http://www.ctan.org/license/lppl1.3 for the details of that license. +Changes in version 1.55 +1. Added new option stix2 to newtxmath, resulting in using Roman and Greek letters from STIX2 with symbols from newtxmath. +2. Modified the handling of secondary alphabets loaded not using \DeclareMathAlphabet. These now allow multiple tokens rather than a single one, and provide a way to get to dotlessi and dotlessj if they exists in the secondary alphabet. +3. Added direct links to DSSerif glyphs under the stix2 option, making use of the changes in 2 above. E.g., \varmathbb{A\imath\dots x\alpha} does pretty much what you would expect, passing along \dots and \alpha to be handled by LaTeX, but rendering the other characters using the DSSerif font when under the option stix2. + Changes in version 1.54 Added option noxchvw (or, equivalently, noXchvw) to newtxmath. This affects only math usage with XCharter, supressing the default math italic v and w and in favor of the Charter italic glyphs. (This may lead to problems distinguishing math italic v from Greek math \nu.) diff --git a/Master/texmf-dist/doc/fonts/newtx/newtxdoc.pdf b/Master/texmf-dist/doc/fonts/newtx/newtxdoc.pdf Binary files differindex 3e3b5031543..0aee9d9ef82 100644 --- a/Master/texmf-dist/doc/fonts/newtx/newtxdoc.pdf +++ b/Master/texmf-dist/doc/fonts/newtx/newtxdoc.pdf diff --git a/Master/texmf-dist/doc/fonts/newtx/newtxdoc.tex b/Master/texmf-dist/doc/fonts/newtx/newtxdoc.tex index c67a8fa7108..df822db02cc 100644 --- a/Master/texmf-dist/doc/fonts/newtx/newtxdoc.tex +++ b/Master/texmf-dist/doc/fonts/newtx/newtxdoc.tex @@ -23,12 +23,13 @@ \newtheorem{thm}{Theorem}[section] %\pdfmapfile{=newtx.map} \usepackage[osf,largesc,theoremfont]{newtxtext} -\usepackage[OT1]{fontenc} +\usepackage[T1]{fontenc} \usepackage[varqu,varl]{zi4} %\traceon \usepackage{newtxmath} %\traceoff %\useosf +\DeclareMathSymbol{\bbZ}{\mathord}{lettersA}{218} \usepackage{bm} %SetFonts \makeatletter @@ -48,7 +49,7 @@ This package is meant to be a replacement for Young Ryu's {\tt txfonts}.
