Good idea. I added a 'for example' to the sentence about installing
default-mysql-server. Otherwise this seems ready to me.

+ MariaDB is now the default MySQL variant in Debian, at version 10.1.
+ The &Releasename; release introduces a new mechanism for switching the
+ default variant, using metapackages created from the
+ <systemitem role="package">mysql-defaults</systemitem> source package.
+ For example, installing the metapackage
+ <systemitem role="package">default-mysql-server</systemitem>
+ will install
+ <systemitem role="package">mariadb-server-10.1</systemitem>.
+ Users who had
+ <systemitem role="package">mysql-server-5.5</systemitem> or
+ <systemitem role="package">mysql-server-5.6</systemitem> will have it
+ removed and replaced by the MariaDB equivalent.
+ Similarly, installing
+ <systemitem role="package">default-mysql-client</systemitem>
+ will install
+ <systemitem role="package">mariadb-client-10.1</systemitem>.
+ </para>
+ <important><para>
+ Note that the database binary data file formats are not backwards
+ compatible, so once you have upgraded to MariaDB 10.1 you will
+ not be able to switch back to any previous version of MariaDB or
+ MySQL unless you have a proper database dump. Therefore, before
+ upgrading, please make backups of all important databases with
+ an appropriate tool such as <command>mysqldump</command>.
+ </para></important>
+ <para>
+ The <systemitem role="package">virtual-mysql-*</systemitem> and
+ <systemitem role="package">default-mysql-*</systemitem> packages
+ will continue to exist. MySQL continues to be maintained in Debian,
+ in the <literal>unstable</literal> release.
+ See the <ulink url="https://wiki.debian.org/Teams/MySQL";>Debian MySQL Team
+ wiki page</ulink> for current information about the mysql-related
+ software available in Debian.
