+- Version upgrade to 9.23
+  Highlights in this release include:
+  * Ghostscript now has a family of 'pdfimage' devices
+    (pdfimage8, pdfimage24 and pdfimage32) which produce
+    rendered output wrapped up as an image in a PDF.
+    Additionally, there is a 'pclm' device which
+    produces PCLm format output.
+  * There is now a ColorAccuracy parameter allowing the user
+    to decide between speed or accuracy in ICC color transforms.
+  * JPEG Passthrough: devices which support it can now receive
+    the 'raw' JPEG stream from the interpreter.
+    The main use of this is the pdfwrite/ps2write family of devices
+    that can now take JPEG streams from the input file(s) and write
+    them unchanged to the output (thus avoiding additional
+    quantization effects).
+  * PDF transparency performance improvements
+  * IMPORTANT: We (i.e. Ghostscript upstream) are in the process
+    of forking LittleCMS.
+    LCMS2 is not thread safe, and cannot be made thread safe
+    without breaking the ABI. Our fork will be thread safe,
+    and include performance enhancements (these changes have all
+    be been offered and rejected upstream). We will maintain
+    compatibility between Ghostscript and LCMS2 for a time,
+    but not in perpetuity. Our fork will be available as its own
+    package separately from Ghostscript (and MuPDF).
+  * We have continued the focus on code hygiene in this release
+    cleaning up security issues, ignored return values,
+    and compiler warnings.
+  * The usual round of bug fixes, compatibility changes,
+    and incremental improvements.
+  Incompatible changes
+  * The planned device API tidy has, unfortunately, been
+    indefinitely postponed, until appropriate resources
+    are available.
