 Release Notes for Version 2.73

 The asygl library was updated to support embedding of WebGL and
 WebGL2 scenes on the same page.

 
 Release Notes for Version 2.72

 WebGL2 is enabled by default only for examples that use image-based
 lighting.  Multiple output formats in threaded interactive mode are
 now handled correctly.  CPU partial sum indexing is used in the
 3D transparency shader if the compute shader fails to compile.


 Release Notes for Version 2.71

 Support for the portable compressed 3D vector file format V3D was
 added.  The default value of settings.prc was changed to false.
 Efficient order-independent transparency was implemented for
 modern OpenGL platforms and the OSMesa offscreen rendering engine
 (with no interactive transparency support for Mac OS X and WebGL).
 The WebGL library now uses WebGL2 if available.
 Image-based lighting was implemented.
 Many bug fixes and improvements were made to Xasy, allowing objects
 drawn with the graphical editor to be saved to and restored from
 a .xasy file, as well as being exportable to an .asy file.
 A function was added to graph a parametric function with control
 points determined by the specified derivative.
 The recommended PostScript viewer for MSWindows is now Sumatra PDF.
 The workflow for generating transparent PDFs and PNGs was fixed.
 Emacs lasy-mode was patched to work with Emacs >= 23.
 Support for the Language Server Protocol was added.
 Compilation with COMPACT=0 is supported again.
 All threads now return the same error code.
 A remote command-line interface to
 http://asymptote.ualberta.ca is now available.

A bug in the Bezier patch bounds was fixed. Vertex and material data are 
copied from the CPU to GPU only when necessary. The default Headlamp
light was brightened. WebGL output is centered in the viewport, extending 
to the canvas boundary; the precision of planar Bezier surfaces was
increased to avoid artifacts. Fullscreen mode has been fixed; the new 
default maxviewport=(0,0) specifies the screen dimensions. Camera
adjustment was fixed.  Problems with Xasy and interactive signals under 
MSWindows were fixed.  A background color for both 2D and 3D images
can be specified with currentlight.background. Offscreen rendering on 
headless machines has been reinstated; while the setting offscreen has
been removed, one can again configure asy for either onscreen or offscreen 
rendering. Clipping was removed from the slopefield module.
Functions mapArray, mapTemplate, real abs2(pair), and real abs2(triple) 
were implemented. The new Ghostscript transparency model requires
Ghostscript 9.52 or later. The detection of TeX errors was improved.  An array 
segmentation fault was fixed; array dimensions are checked.  Flattened
monochrome tensor patches with interior internal control points are now 
drawn as filled cyclic paths. PDF offsets were fixed, along with the
auto-reload feature for Acroread. SVG support was improved; 2D images can 
now be output in HTML format using inline SVG code, to support the
Asymptote Web Application, a new cloud service at 
http://asymptote.ualberta.ca.

was fixed; outline and mesh mode were ported to WebGL. Degenerate
surface normals were fixed. The octant1, hemisphere, and sphere
surfaces were replaced by nondegenerate versions that render faster.
The unitcone, unitfrustum, and DefaultHead3 arrowhead were simplified.
A robust and more efficient tube routine was implemented;
the PRC tube primitive was removed. WebGL compression was achieved by
implementing sphere, disk, cylinder, and tube primitives in the AsyGL 
library. 
Patches are now split in both directions only when required.
If the GNU Readline library is unavailable, the Editline library
is used to at least support command-line editing, without history 
features.
An MSDOS configuration issue was fixed.

CTAN update: asymptote

[CTAN Announcements]

John Bowman submitted an update to the

asymptote

package.

Version number: 2.62
License type: lgpl3

Summary description: 2D and 3D TeX-Aware Vector Graphics Language

Announcement text:
--


A hyperbola(point F1, point F2, point M) function was added to the 
geometry module. Duplicate intersections are avoided. Errors in the 
texpreamble are handled gracefully, without hanging. Unwanted indentation 
under LuaLaTex was removed. The WebGL canvas is populated with the design 
width and height. The WebGL context is stored in the top rather than 
parent window. To avoid polling, WebGL images now draw directly.
Zooming of embedded WebGL images is disabled until activated with a click 
or touch event, using ESC to cancel activation. WebGL usage comments now 
suggest embedding as an iframe rather than an object. The obsolete grffile 
package is no longer used. Typos in the documentation were fixed.

 Transparent WebGL backgrounds were fixed. A build issue involving the revision
 number was fixed. The locatefile function now returns the fully qualified
 file name. The htmlviewer uses the absolute path for all platforms;
 it is also used for displaying svg files. SVG output for embedded PNG, JPEG,
 and external vector EPS and PDF images is supported with the latex TeX
 engine and dvisvgm 2.8. The simplex solver was optimized. A pad function that
 pads a picture to a precise size in both directions was introduced.
 The xasy front end was ported to high-resolutions screens and handles Ctrl-C
 interrupts correctly. Objects can be positioned finely with the arrow keys
 while holding down the mouse button. The origin/center order and anchor names
 were fixed. A front/back detection bug in the solids module was fixed.
 The grffile package fixes issues with included file names.
 This release requires Version 1.34 of asymptote.sty (auto-generated).

library. Multiple embedded images now share a single WebGL context and 
shaders, to work around browser limitations. A bug in 3D arrows was fixed. 
Unavailable material attributes are now ignored. Miscellaneous Python 
support files were ported to Python3. The obsolete maxvertices setting was 
removed.

Intersection points in geometry.asy are now returned in currentcoordsys; a 
numerical precision issue was also fixed. Ambiguous function signatures in 
geometry.asy are resolved by requiring explicit casts when converting 
general forms to special cases. The xasy editor selection is now 
consistent. Building the asymptote.so shared library is supported again. 
A bug in rendering indexed triangle arrays was fixed. Execution errors in 
support utilities are now handled gracefully. Due to current limitations 
of dvisvgm (2.7.4), graphic() can only display SVG output (used by the 
xasy vector editor) for external vector EPS graphics (embedded images, 
PDF, PNG, and JPG formats are not yet supported). Building under CYGWIN 
with X11 is supported again. The --version option lists both enabled and 
disabled features. The GLX library is explicitly linked if present.

Release Notes for Version 2.55

An initialization bug in the OpenGL renderer and portability issues were
fixed. 

Release Notes for Version 2.54

Support for generating and embedding interactive 3D WebGL vector graphics 
within an HTML file has been added, allowing Asymptote figures to be 
displayed on modern mobile and desktop browsers. The OpenGL rendering 
routines were further optimized, yielding higher frame rates and lower 
memory usage. The view position for perspective projection was fixed. The 
default value of file word() was fixed. Installation issues were 
addressed. A new digits setting controls the default output file 
precision. A hanging pipe was fixed. The popcount function was extended to 
systems that lack 64-bit integers. The order of PRC quad colours was 
fixed. If lighting is enabled, vertex colors are now ignored in PRC 
images; when drawing a surface s, use draw(s,prc() ? nolight : 
currentlight); to disable lighting manually and recover the old behaviour.

The xasy graphical user interface now runs under both Python 2.7 and 
Python 3.  Legacy versions (prior to 9.14) of Ghostscript can be
supported by assigning settings.epsdriver="epswrite" (or by setting the 
environment variable ASYMPTOTE_EPSDRIVER to epswrite). The
quiet flag suppresses noninteractive standard output when 
settings.verbosity <= 1. A progress function was added to the 
plain_strings
module. The smoothcontour3 module was optimized to use Bezier triangles 
where appropriate, along with a built-in least-squares routine
and an improved root finder based on quadratic interpolation. If 
settings.sysdir is empty, preference is given to a version of
kpsewhich in the same directory as the executable for determining the 
correct sysdir. The handling of degenerate normals of Bezier
triangles was fixed. Bugs in forking, integer formatting, dash adjustment, 
subpaths, and guide reversion were fixed. Version 1.30 of

asymptote.sty (auto-generated) and version 0.35 (or later) of media9.sty
