+    A dump/restore is not required for those running 7.4.X.
+    However, if you are upgrading from a version earlier than 7.4.26,
+    see the release notes for 7.4.26.

+      Add new configuration parameter <varname>ssl_renegotiation_limit</> to
+      control how often we do session key renegotiation for an SSL connection
+      (Magnus)
+     </para>
+
+     <para>
+      This can be set to zero to disable renegotiation completely, which may
+      be required if a broken SSL library is used.  In particular, some
+      vendors are shipping stopgap patches for CVE-2009-3555 that cause
+      renegotiation attempts to fail.

+      Make <function>substring()</> for <type>bit</> types treat any negative
+      length as meaning <quote>all the rest of the string</> (Tom)
+     </para>
+
+     <para>
+      The previous coding treated only -1 that way, and would produce an
+      invalid result value for other negative values, possibly leading to
+      a crash (CVE-2010-0442).

+     <para>
+      When reading <filename>pg_hba.conf</> and related files, do not treat
+      <literal>@something</> as a file inclusion request if the <literal>@</>
+      appears inside quote marks; also, never treat <literal>@</> by itself
+      as a file inclusion request (Tom)
+     </para>
+
+     <para>
+      This prevents erratic behavior if a role or database name starts with
+      <literal>@</>.  If you need to include a file whose path name
+      contains spaces, you can still do so, but you must write
+      <literal>@"/path to/file"</> rather than putting the quotes around
+      the whole construct.

+      The only known symptom of this oversight is that the Tcl
+      <literal>clock</> command misbehaves if using Tcl 8.5 or later.
