Sorry I couldn't reply sooner, but the following of your proposed text
needs to be updated a bit:

+ <listitem>
+ <para>
+ Having a "default" partition for storing data that does not match a
+ partition key
+ </para>
+ </listitem>

I think "does not match a partition key" is not accurate. Description of
default partitions further below in the release notes says this:

"The default partition can store rows that don't match any of the other
defined partitions, and is searched accordingly."

So, we could perhaps write it as:

Having a "default" partition for storing data that does not match any of
the remaining partitions

Thanks,
Amit
