 Release Notes for Version 2.57

 Scenes with lighting disabled are rendered correctly in WebGL.
 Attempting to output HTML for 2D pictures produces an SVG file.
 A conditional was removed from the fragment shaders. A viewportshift
 option
 was added to the WebGL driver; the home (h) option now forces a remesh.
 The version number was removed from the local offline copy of asygl.
 A numerical degeneracy in the conic sections intersection routine
 was fixed. A workaround for the broken XDR headers under MacOS X was
 implemented. An issue with animations was fixed. The --version option
 displays
 a list of compiled-in features.
 Release Notes for Version 2.58

 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.

 Comment from Karl Berry on tlbuild:

 I committed the asymptote-2.58 sources to TeX Live. John says this
 release should be stable and has many enhancements over what we released
 with the original TL19. So if everyone is up for trying to compile it,
 and it succeeds, it seems like it would be worth updating now instead of
 waiting until next year.
