 <h3><a name="Version8.62"></a>Version 8.62 (2008-02-29)</h3>
 
-<p>This is and unreleased development shapshot.
-
+<p>
+This version is the next in our line of scheduled semi-annual releases.
+<p>
+There were approximately 55 bugs fixed since version 8.61. Some fixes
+and improvements of note were:
+<p>
+COMPILE_INITS=1 was broken in 8.61 and now works as expected.
+<p>
+Fonts are now distributed in the Resource/Font directory and will be
+included in the executable if COMPILE_INITS=1
+<p>
+The tiffsep device was fixed for using more than 8 colorants.
+<p>
+Shadings, overprinting and transparency were optimized and are substantially
+faster than in 8.61, particularly for large format or high resolution
+rendering when using the 'clist' banding mode.
+<p>
+Changes were made to prevent near unbounded growth in memory usage and
+corresponding performance problems on a few test cases.
+<p>
+The 'pdfwrite' device was improved to fix some compatibility issues with
+PDF/A and to improve some font embedding and other issues.
+<p>
+The 'ht_ccsto.ps' Stochastic Threshold array was completely changed to
+be more useful. The values in the threshold array were inverted, so
+the number of 'light' colors was limited and using it generally caused
+prints that were too dark.
+<p>
+The 'runpdfbegin', 'dopdfpages' and 'runpdfend' PostScript pseudo-operators
+that were inadvertently removed in 8.61 were restored. This also restored
+the functionality of toolbin/pdf_info.ps to display PDF creator stats,
+fonts used and page sizes.
+<p>
+The halftone tile cache sizes and cache effectiveness were improved to
+help the performance when tiling with large cells or threshold arrays.

 <h3><a name="8.62_Incompatible_changes"></a>Incompatible changes</h3>
 
 <p>
-There are no known incompatibile changes in this release.
+Not strictly a compatibility issue, but the default URW (GPL) fonts are now
+distributed in the Resource/Font/ path which can increase the number of
+file handles open for PostScript that opens all of the resources. Also
+the size of the %rom% rom file system within the executable when using
+COMPILE_INITS=1 is larger by the amount needed for the fonts.
+<p>
+Also not strictly incompatible, but some alternate fixed-point code 
+was stripped out, so FPU_TYPE and other FPU related makefile macros
+are gone or don't cause any difference in the code generated. Also the 
+'USE_ASM' macro was removed, since we expect modern compilers to do 
+sufficient optimization.
+<p>
+Some old (deprecated) "helper" scripts were removed: gsindent, gssubst,
+many2pdf.tcl, and pre.
+<p>
+The unused 'cmap' (special color mapping) and 'ropc' devices were 
+removed from the distribution.
+<p>
+The 'ht_ccsto.ps' Stochastic Threshold array was completely changed to
+be more useful. The values in the threshold array were inverted, so
+the number of 'light' colors was limited and using it generally caused
+prints that were too dark. This is an improvement, but incompatible
+in that anyone using it previously would see much different grays/
+colors.
+<p>
+The SYSTEM_CONSTANTS_ARE_WRITABLE compile time define was removed
+as was the "EXTEND_NAMES" makefile macro (still accessible using
+a compiler flag define).
