+Snapshot 1.3.10 (2006-12-23 Carl Worth <cworth@cworth.org>)
+===========================================================
+Santa Claus is coming just a little bit early this year, and he's
+bringing a shiny new cairo snapshot for all the good little boys and
+girls to play with.
+
+This is the fifth development snapshot in the 1.3 series. It comes 9
+days after the 1.3.8 snapshot, and still well within our goal of
+having a new snapshot every week, (though don't expect one next
+week---we'll all be too stuffed with sugar plums).
+
+Speaking of sugar plums, there's a sweet treat waiting in this cairo
+snapshot---greatly improved performance for stroking rectilinear
+shapes, like the ever common rectangle:
+
+image-rgb          box-outline-stroke-100 0.18 -> 0.01: 25.58x speedup
+████████████████████████▋
+image-rgba         box-outline-stroke-100 0.18 -> 0.01: 25.57x speedup
+████████████████████████▋
+xlib-rgb          box-outline-stroke-100 0.49 -> 0.06:  8.67x speedup
+███████▋
+xlib-rgba         box-outline-stroke-100 0.22 -> 0.04:  5.39x speedup
+████▍
+
+In past releases of cairo, some people had noticed that using
+cairo_stroke to draw rectilinear shapes could be awfully slow. Many
+people had worked around this by using cairo_fill with a more complex
+path and gotten a 5-15x performance benefit from that.
+
+If you're one of those people, please rip that workaround out, as now
+the more natural use of cairo_stroke should be 1.2-2x faster than the
+unnatural use of cairo_fill.
+
+And if you hadn't ever implemented that workaround, then you just
+might get to see your stroked rectangles now get drawn 5-25x faster.
+
+Beyond that performance fix, there are a handful of bug fixes in this
+snapshot:
+
+ * Fix for glyph cache race condition in glitz backend (Jinghua Luo)
+
+ * Many fixes for ATSUI text rendering (Brian Ewins)
+
+ * Un-break recent optimization-triggered regression in rendering text
+   with a translation in the font matrix (Behdad Esfahbod)
+
+ * Fix make check to work on OPD platforms (IA64 or PPC64)
+   (Frederic Crozat)
+
+ * Fix a couple of character spacing issues on Windows
+    (Jonathan Watt)
+
+Have fun with that, everybody, and we'll be back for more in the new
+year, (with a plan to add the last of our performance improvements in
+this round, fix a few bad, lingering bugs, and then finish off a nice,
+stable 1.4 release before the end of January).
