+                    Prior to this release, you set the
+                    <filename>TEST_IMAGE</filename> variable to "1" to
+                    enable automatic testing for successfully built images.
+                    The <filename>TEST_IMAGE</filename> variable no longer

+            <ulink url='https://www.openssl.org/'>OpenSSL</ulink> has been
+            upgraded from 1.0 to 1.1.
+            By default, this upgrade could cause problems for recipes that
+            have both versions their dependency chains.
+            The problem is that both versions cannot be installed together
+            at build time.
+            <note>
+                It is possible to have both versions of the library at runtime.

+            The Poky distribution now uses security compiler files by

+            Inclusion of these files could cause new failures due to stricter
