<scode>
Remove part of the deprecated Servlet 4 Preview API. Users still
depending on this feature should ideally upgrade to Tomcat 9.0.x. If

Tomcat implementation classes. (markt)

<update>
<bug>63691</bug>: Skip all jar and directory scanning when the wildcard

<bug>64008</bug>: Clarify/expand the Javadoc for the
<code>Tomcat#addWebapp()</code> and related methods. (markt)

SCI definitions from JARs unpacked into <code>WEB-INF/classes</code> are
now handled consistently and will always be found irrespective of

<update>
The minimum required Tomcat Native version has been increased to 1.2.14.
This version includes a new API needed for correct client certificate
support when using a Java connector with OpenSSL TLS implementation and
support for the <code>SSL_CONF</code> OpenSSL API. (rjung)
</update>
<add>
Add support for the OpenSSL <code>SSL_CONF</code> API when using
TLS with OpenSSL implementation. It can be used by adding
<code>OpenSSLConf</code> elements underneath <code>SSLHostConfig</code>.
The new element contains a list of <code>OpenSSLConfCmd</code> elements,
each with the attributes <code>name</code> and <code>value</code>.
(rjung)
</add>
<fix>
When using a Java connector in combination with the OpenSSL TLS
implementation, do not configure each SSL connection object via
the OpenSSLEngine. For OpenSSL the SSL object inherits its
settings from the SSL_CTX which we have already configured.
(rjung)
</fix>
<fix>
When using JSSE TLS configuration with the OpenSSL implementation and
client certificates: include client CA subjects in the TLS handshake
so that the client can choose an appropriate client certificate to
present. (rjung)
</fix>
<fix>
If an invalid option is specified for the
<code>certificateVerification</code> attribute of an
<code>SSLHostConfig</code> element, treat it as <code>required</code>
which is the most secure / restrictive option in addition to reporting
the configuration error. (markt)

<code>Mapper</code> used is the <code>Mapper</code> associated with the
<code>Service</code> for which the listener was created. (markt)
</scode>
<add>
Move the functionality that provides redirects for context roots and
directories where a trailing <code>/</code> is added from the Mapper to
the <code>DefaultServlet</code>. This enables such requests to be
processed by any configured Valves and Filters before the redirect is
made. This behaviour is configurable via the
<code>mapperContextRootRedirectEnabled</code> and
<code>mapperDirectoryRedirectEnabled</code> attributes of the Context
which may be used to restore the previous behaviour. (markt)

<add>
<bug>56917</bug>: As per RFC7231 (HTTP/1.1), allow HTTP/1.1 and later

</fix>
<fix>
<bug>58655</bug>: Fix an <code> IllegalStateException</code> when
calling <code>HttpServletResponse.sendRedirect()</code> with the
<code>RemoteIpFilter</code>. This was caused by trying to correctly
generate the absolute URI for the redirect. With the fix for
<bug>56917</bug>, redirects may now be relative making the
<code>sendRedirect()</code> implementation for the
<code>RemoteIpFilter</code> much simpler. This also addresses issues
where the redirect may not have behaved as expected when redirecting
from http to https to from https to http. (markt)

NIO + OpenSSL if tomcat-native is available, rather than the APR

<add>
Extend the feature available in the cluster session manager
implementations that enables session attribute replication to be
filtered based on attribute name to all session manager implementations.
Note that configuration attribute name has changed from
<code>sessionAttributeFilter</code> to
<code>sessionAttributeNameFilter</code>. Apply the filter on load as
well as unload to ensure that configuration changes made while the web
application is stopped are applied to any persisted data. (markt)
</add>
<add>
Extend the session attribute filtering options to include filtering
based on the implementation class of the value and optional
<code>WARN</code> level logging if an attribute is filtered. These
options are available for all of the Manager implementations that ship
with Tomcat. When a <code>SecurityManager</code> is used filtering will
be enabled by default. (markt)
</add>

Correct a regression in the fix for <bug>58867</bug>. When configuring a
Context to use an external directory for the <code>docBase</code>, and

Refactor the web.xml parsing so a new parser is created every time the
