-Release notes for version 1.9 of the dvipng package:
+Release notes for version 1.10 of the dvipng package:
This program makes PNG graphics from DVI files as obtained from TeX
and its relatives.
-The 1.9 release adds CJK (Chinese, Japanese and Korean) support, more
-specifically it adds support for the subfonts used in the CJK-latex
-package.
+From v 1.10, dvipng will be available under the LGPL rather than the
+GPL. This is because the GPL restricts inclusion in some rendering
+systems out there. I have decided to change to LGPL because a) there
+are other possible albeit slower conversion paths from DVI to PNG, and
+b) dvipng has been available (pre-release and release) for five years
+now, which should be enough of a head start for the GNU community.
-TrueType fonts have been tested somewhat more, and the ttfonts.map
-file is now used, if present on the system.
-It also fixes a few bugs, most notably a version problem with
-Freetype<2.1.8, and a graphics inclusion bug for non-.-paths.
+The main code addition is limited support for literal PostScript
+specials, using gs. For example, most of the PSTricks package can now
+be rendered using dvipng. Unfortunately, dvipng can only handle
+drawing PostScript code at the moment, not PostScript code intended to
+make dvips + gs scale, rotate, or move DVI glyphs (characters). This
+is because the graphics state cannot be communicated back to dvipng
+from gs. So no guarantees. Also, the performance in terms of runtime
+could be better.
+
+Other changes include internal changes to the DVI stack, DVI flags,
+some build issues on AIX and glyph-index-checking fixes.
