+This file, current.txt, describes problems and new features in the current
+release of Ghostscript. This file describes version 5.13 of Ghostscript.
+
+For an overview of Ghostscript and a list of the documentation files, see
+README.
+
+New features (since release 5.03)
+============
+
+(This is not a complete list of new features: see NEWS for details.)
+
+ps2pdf (and the pdfwrite device) now produces much more compact output. By
+default, the output is compatible only with Acrobat 3.x; for Acrobat
+2.x-compatible output, use
+ ps2pdf -dCompatibilityLevel=1.1 ...
+
+ps2pdf now has more flexibility about the handling of unencoded glyphs. See
+gdevpdft.c for details.
+
+ps2pdf now recognizes the CompressPages, CompatibilityLevel, and
+UseFlateCompression device (distiller) parameters.
+
+The PDF interpreter now handles Lab and Separation color spaces, images with
+color space resources, embedded font subsets, undefined operators with
+BX/EX, and Functions.
+
+Changes
+=======
+
+The RGB<->CMYK conversion rules have been changed back to Adobe's documented
+rules.
+
+Known problems
+==============
+
+(This is not a complete list of known problems: see NEWS for details.)
+
+Usage
+-----
+
+On a MS-DOS system, interrupting the interpreter by typing ^C doesn't
+restore the display mode.
+
+Limitations
+-----------
+
+serialnumber returns the same value in all copies.
+
+Some floating point exceptions terminate the interpreter, rather than
+producing a limitcheck error.
+
+The DCTEncode filter disregards the Blend parameter, and uses different
+QuantTables and HuffTables from Adobe's.
+
+The DCT filters do not support nonintegral sample ratios. Also, DCTEncode
+will not create files with Sum(HS*VS)>10 (regardless of the value of the
+Relax parameter) because they violate the JPEG standard; but DCTDecode will
+read such files.
+
+The size of the execution stack cannot be changed dynamically. (However,
+the sizes of the operand and dictionary stacks can be changed.)
+
+Separation color spaces are implemented, but devices that actually produce
+color separations are not supported. The special color separations All and
+None, and the primary separations (Red, Green, etc.), are not supported.
+
+execform and ucache are implemented, but they do not actually do any
+caching; setucacheparams and ucachestatus are dummies. (This only impacts
+performance, not functionality.)
+
+The image operator only honors the Interpolate flag in the image dictionary
+if the combined transformation (ImageMatrix + CTM) doesn't involve rotation,
+skewing, or X-reflection; imagemask doesn't honor Interpolate at all.
+
+Some path building operations that would generate a device coordinate larger
+than +/-2^19 will cause a limitcheck. However, the common ones ([r]moveto,
+[r]lineto, [r]curveto, closepath) will not.
+
+Graphics bugs
+-------------
+
+Opening more than one window device at the same time doesn't work.
+This is the case for both X Windows and Microsoft Windows.
+
+cshow doesn't work with composite fonts.
+
+Non-graphics bugs
+-----------------
+
+The %statementedit pseudo-file is equivalent to %lineedit. As a
+consequence, the interactive interpreter requires that every statement fit
+on a line, i.e., you can't have an unpaired (, {, or <.
+
+The following operators that expect arrays won't accept packed arrays:
+ definefont (Subrs (type 1 fonts))
+
+Syntax errors occurring within a binary token do not produce the error
+message specified by the Adobe documentation.
+
+save doesn't save, and restore doesn't restore, the user parameters.
