Refactor creation of MapperListener to ensure that the Mapper used is the Mapper associated with the Service for which the listener was created. (markt)
Move the functionality that provides redirects for context roots and directories where a trailing / is added from the Mapper to the DefaultServlet.

Fixed potential NPE in HostConfig while deploying an application. Issue reported by coverity scan. (violetagg)
58655: Fix an IllegalStateException when calling HttpServletResponse.sendRedirect() with the RemoteIpFilter. This was caused by trying to correctly generate the absolute URI for the redirect. With the fix for 56917, redirects may now be relative making the sendRedirect() implementation for the RemoteIpFilter 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)
58657: Exceptions in a Servlet 3.1 ReadListener or WriteListener do not need to be immediately fatal to the connection. Allow an error response to be written. (markt)

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)
Extend the session attribute filtering options to include filtering based on the implementation class of the value and optional WARN level logging if an attribute is filtered. These options are available for all of the Manager implementations that ship with Tomcat. When a SecurityManager is used filtering will be enabled by default. (markt)
Remove distributable and maxInactiveInterval from the Manager interface because the attributes are never used. The equivalent attributes from the Context always take precedence. (markt)

When configuring a Context to use an external directory for the docBase, and that directory happens to be located along side the original WAR, use the directory as the docBase rather than expanding the WAR into the appBase and using the newly created expanded directory as the docBase. (markt)
58988: Special characters in the substitutions for the RewriteValve can now be quoted with a backslash. (fschumacher)
58999: Fix class and resource name filtering in WebappClassLoader. It throws a StringIndexOutOfBoundsException if the name is exactly "org" or "javax". (rjung)
Add JASPIC (JSR-196) support. (markt)
Make checking for var and map replacement in RewriteValve a bit stricter and correct detection of colon in var replacement. (fschumacher)
Refactor the web application class loader to reduce the impact of JAR scanning on the memory footprint of the web application. (markt)
Fix some resource leaks in the error handling for accessing files from JARs and WARs. (markt)
Refactor the JAR and JAR-in-WAR resource handling to reduce the memory footprint of the web application. (markt)
Refactor the web.xml parsing so a new parser is created every time the web application starts rather than creating and caching the parser when the Context is created. This enables the parser to take account of modified Context configuration parameters and reduces (slightly) the memory footprint of a running Tomcat instance. (markt)
Switch the web application class loader to the ParallelWebappClassLoader by default. (markt)
57809: Remove the custom context attribute that held the effective web.xml. Components needing access to configuration information may access it via the Servlet API. (markt)
Refactor JAR scanning to reduce memory footprint. (markt)
59001: Correctly handle the case when Tomcat is installed on a path where one of the segments ends in an exclamation mark. (markt)
Expand the fix for 59001 to cover the special sequences used in Tomcat's custom jar:war: URLs. (markt)
59043: Avoid warning while expiring sessions associated with a single sign on if HttpServletRequest.logout() is used. (markt)
59054: Ensure that using the CrawlerSessionManagerValve in a distributed environment does not trigger an error when the Valve registers itself in the session. (markt)
Add socket properties support to storeconfig. (remm)
Fix incorrect parsing of the NE and NC flags in rewrite rules. (remm)
59065: Correct the timing of the check for colons in paths on non-Windows systems implemented in catalina.sh so it works correctly with Cygwin. Patch provided by Ed Randall. (markt)
When a Host is configured with an appBase that does not exist, create the appBase before trying to expand an external WAR file into it. (markt)
59115: When using the Servlet 3.0 file upload, the submitted file name may be provided as a token or a quoted-string. If a quoted-string, unquote the string before returning it to the user. (markt)
59123: Close NamingEnumeration objects used by the JNDIRealm once they are no longer required. (fschumacher/markt)
Implement the proposed Servlet 4.0 API to provide mapping type information for the current request. (markt)
59138: Correct a false positive warning for ThreadLocal related memory leaks when the key class but not the value class has been loaded by the web application class loader. (markt)
59017: Make the pre-compressed file support in the Default Servlet generic so any compression may be used rather than just gzip. Patch provided by Mikko Tiihonen. (markt)
59145: Don't log an invalid warning when a user logs out of a session associated with SSO. (markt)
59150: Add an additional flag on APR listener to allow disabling automatic use of OpenSSL. (remm)
59151: Fix a regression in the fix for 56917 that added additional (and arguably unnecessary) validation to the provided redirect location. (markt)
59154: Fix a NullPointerException in the JAASMemoryLoginModule resulting from the introduction of the CredentialHandler to Realms. (schultz/markt)

Coyote

Remove support for the HTTP BIO and AJP BIO connectors. (markt)
Refactor HTTP upgrade and AJP implementations to reduce duplication. (markt)
Add support for HPACK header encoding and decoding, contributed by Stuart Douglas. (remm)
57108: Add support for Server Name Indication (SNI). There has been significant changes to the SSL configuration in server.xml to support this. (markt)
Add SSL engine for JSSE backed by OpenSSL. Includes ALPN support. Based on code contributed by Numa de Montmollin and derived from code developed by Twitter and Netty. (remm)
RFC 7230 states that clients should ignore reason phrases in HTTP/1.1 response messages. Since the reason phrase is optional, Tomcat no longer sends it. As a result the system property org.apache.coyote.USE_CUSTOM_STATUS_MSG_IN_HEADER is no longer used and has been removed. (markt)
The minimum required Tomcat Native version has been increased to 1.2.2. The 1.2.x branch includes ALPN and SNI support which are required for HTTP/2. (markt)
Add support for HTTP/2 including server push. (markt)
58621: The certificate chain cannot be set using the main certificate attribute, so restore the certificate chain property. (remm)
Allow a new SSL config type where a connector can use either JSSE or OpenSSL. Both could be allowed, but it would likely create support issues. This type is used by the OpenSSL implementation for NIOx. (remm)
Improve upgrade context classloader handling by using Context.bind and unbind. (remm)
Improve OpenSSL keystore/truststore configuration by using the code from the JSSE implementation. (remm, jfclere)
Fix a potential loop when a client drops the connection unexpectedly. (markt)
OpenSSL renegotiation support for client certificate authentication. (remm)
Fix NIO connector renegotiation. (remm)
58659: Fix a potential deadlock during HTTP/2 processing when the connection window size is limited. (markt)

Bad processing of handshake errors in NIO2. (remm)
Use JSSE session configuration options with OpenSSL. (remm)
59015: Fix potential cause of endless APR Poller loop during shutdown if the Poller experiences an error during the shutdown process. (markt)
Align cipher aliases for kECDHE and ECDHE with the current OpenSSL implementation. (markt)
59081: Retain the user defined cipher order when defining ciphers. (markt)
59089: Correctly ignore HTTP headers that include non-token characters in the header name. (markt)

59119: Correct read logic for WebSocket client when using secure connections. (markt)
59134: Correct client connect logic for secure connections made through a proxy. (markt)

Web applications

48674: Implement an option within the Host Manager web application to persist the current configuration. Based on a patch by Coty Sutherland. (markt)
58631: Correct the continuation character use in the Windows Service How-To page of the documentation web application. (markt)

Document test.threads option in BUILDING.txt. (kkolinko)
Correct an error in the documentation of the expected behaviour for automatic deployment. If a WAR is updated and an expanded directory is present, the directory will always be deleted and recreated by expanding the WAR if unpackWARs is true. (markt)
58935: Remove incorrect references in the documentation to using jar:file: URLs with the Manager application. (markt)
Correct the description of the ServletRequest.getServerPort() in Proxy How-To. Issue reported via comments.apache.org. (violetagg)
The Manager and Host Manager applications are now only accessible via localhost by default. (markt)

Tribes

Clarify the handling of Copy message and Copy nodes. (kfujino)
Ensure that the static member is registered to the add suspect list even if the static member that is registered to the remove suspect list has disappeared. (kfujino)
When using a static cluster, add the members that have been cached in the membership service to the map members list in order to ensure that the map member is a static member. (kfujino)
Add support for the startup notification of local members in the static cluster. (kfujino)
Ignore the unnecessary member remove operation from different domain. (kfujino)
Add support for the shutdown notification of local members in the static cluster. (kfujino)
If promoting a proxy node to a primary node when getting a session, notify the change of the new primary node to the original backup node. (kfujino)

Correct evaluation of system property org.apache.tomcat.jdbc.pool.onlyAttemptCurrentClassLoader. It was basically ignored before. Reported by coverity scan. (fschumacher)
Fix potential integer overflow in ConnectionPool and PooledConnection. Reported by coverity scan. (fschumacher)

Other

Allow to configure multiple JUnit test class patterns with the build property test.name and document the property in BUILDING.txt. (rjung)
Support the use of the threads attribute on Ant's junit task. Note that using this with a value of greater than one will disable Cobertura code coverage. (markt)
Update optional Checkstyle library to 6.14.1. (kkolinko)
