+      <p>&os; has been updated to allow it to use the VFP variant of the
+	ARM EABI ABI.  The VFP unit is the ARM hardware to perform
+	floating-point operations.  This changes the ABI to improve the
+	performance of code that uses floating-point operations.  By
+	default, &os; already uses the ARM EABI on all releases from
+	10.0.</p>
+
+      <p>This is important for users of &os;/arm with an ARMv6 or ARMv7
+	SoC and who use code that makes use of floating-point
+	operations.  It removes the need for the slow software
+	floating-point support in <tt>libc</tt>.  This is mostly
+	compatible with the existing ABI, with the exception of how
+	floating-point values are passed into functions.  Because no
+	floating-point values are passed to the kernel, the
+	<tt>armv6</tt> and <tt>armv6hf</tt> kernels will work with
+	either userland.</p>
+
+      <p>As part of this, some support functions have been updated to
+	use the VFP unit when available.  It is intended the existing
+	<tt>armv6</tt> target architecture will be kept for cases where
+	the SoC lacks a VFP unit, or existing binaries that are
+	incompatible with the new ABI.</p>
