+- User fonts:  This is new API allowing the user of cairo API to provide
+  drawings for glyphs in a font.  This is most useful in implementing
+  fonts in non-standard formats, like SVG fonts and Flash fonts, but can
+  also be used by games and other application to draw "funky" fonts.
+  See test/user-font.c and test/user-font-proxy.c for usage examples.
+
+  Note that user font API changed a bit just before this release.
+
+- show_text_glyphs:  This is new API allowing the caller of cairo to mark
+  text glyphs with their original text.  The PDF backend implements this
+  new API and latest Pango master uses it.  The result is (when bugs are
+  fixed) that complex text can be copied out of pangocairo's PDF output
+  correctly and reliably.  There are bugs to fix though.  A few poppler
+  bugs, and some more in cairo and pango.
+
+  To test show_text_glyph, just grab pango master & this cairo snapshot and
+  print text in gedit.  Open in acroread or evince, select all, copy, paste
+  in gedit and compare.  The Arabic text with diacritic marks is particularly
+  showing bad.  Try with pango/pango-view/HELLO.txt if you are brave
+  enough.  The Indic text is showing improvements, but is still coming out
+  buggy.
+
+- text_to_glyphs API:  This is mostly useful in combination with user-fonts.
+
+The result of the above three changes combined is that when you render text
+using cairo_show_text() and a user font, the resulting PDF file is perfectly
+text extractable.  Something one could not do with cairo before.
+
+- Toy font face constructor and getters:  Mostly for API completion, but
+  also useful for higher level (like Pango) to hook into what the user
+  has set using cairo_select_font_face(), making that toy API a bit more
+  useful.
+
+- LCD subpixel filtering using FreeType, with different filters.  Original
+  patch by David Turner.
+
+
+Known issues:
+
+- Type3 fonts generated by cairo's PDF backend may show up in poppler/Evince
+  in a different color than expected.  This is fixed in poppler master branch.
+  This mostly affects cairo user fonts.  The test case test/user-font.c
+  demonstrates this.
+
+- User fonts using other fonts in their rendering are currently embedded in
+  PDF as fallback bitmap glyphs.  This will be (hopefully) fixed before 1.8.
+  The test case test/user-font-proxy.c demonstrates this.
+
+- The win32 font backend does not work in this version.  This will be fixed
+  as soon as possible.

 =========================================================
 The cairo community is wildly embarrassed to announce the 1.6.4
