There is no ordering by add/update/fix/scode/docs/design.
Other fixed issues are added to the end of the list, chronologically.

incomplete if the connection is closed before the response is fully
written due to a write timeout. (markt)

<bug>60781</bug>: Escape elements in the access log that need to be
escaped for the access log to be parsed unambiguously.
(fschumacher/markt)
</fix>
<add>
<bug>64110</bug>: Add support for additional TLS related request
attributes that provide details of the protocols and ciphers requested
by a client in the initial TLS handshake. (markt)
</add>
<add>
Let the <code>RemoteCIDRValve</code> inherit from
<code>RequestFilterValve</code> and support all of its features.
Especially add support for connector specific configuration
using <code>addConnectorPort</code>. (rjung)
</add>
<add>
Add <code>peerAddress</code> to coyote request, which contains
the IP address of the direct connection peer. If a reverse proxy
sits in front of Tomcat and the protocol used is AJP or HTTP
in combination with the <code>RemoteIp(Valve|Filter)</code>,
the peer address might differ from the <code>remoteAddress</code>.
The latter then contains the address of the client in front of the
reverse proxy, not the address of the proxy itself.
Support for the peer address has been added to the
RemoteAddrValve and RemoteCIDRValve with the new attribute
<code>usePeerAddress</code>. This can be used to restrict access
to Tomcat based on the reverse proxy IP address, which is especially
useful to harden access to AJP connectors. The peer address can also
be logged in the access log using the new <code>%{peer}a</code>
syntax. (rjung)
