Tomcat 8.5.43 (markt)
Catalina
Update: Modify the Default and WebDAV Servlets so that a 405 status code is returned for PUT and DELETE requests when disabled via the readonly initialisation parameter.
Fix: Align the contents of the Allow header with the response code for the Default and WebDAV Servlets. For any given resource a method that returns a 405 status code will not be listed in the Allow header and a method listed in the Allow header will not return a 405 status code. (markt)

Fix: Improve parsing of Range request headers. (markt)
Fix: Range headers that specify a range unit Tomcat does not recognise should be ignored rather than triggering a 416 response. Based on a pull request by zhanhb. (markt)
Fix: When comparing a date from a If-Range header, an exact match is required. Based on a pull request by zhanhb. (markt)
Fix: Add an option to the default servlet to disable processing of PUT requests with Content-Range headers as partial PUTs. The default behaviour (processing as partial PUT) is unchanged. Based on a pull request by zhanhb. (markt)
Fix: Improve parsing of Content-Range headers. (markt)
Fix: Ensure that the HEAD response is consistent with the GET response when HttpServlet is relied upon to generate the HEAD response and the GET response uses chunking. (markt)

2018-08-17 Tomcat 8.5.33 (markt)
Catalina
Fix: Ensure that the HTTP Vary header is set correctly when using the CORS filter and improve the cacheability of requests that pass through the COPRS filter. (markt)
Fix: 62527: Revert restriction of JNDI to the java: namespace. (remm)

Fix: 62507: Ensure that JSSE based TLS connectors work correctly with a DKS keystore. Note: DKS keystores require Java 8 or later. (markt)
Fix: Refactor code that adds an additional header name to the Vary HTTP response header to use a common utility method that addresses several additional edge cases. (markt)
Fix: 62515: When a connector is configured (via setting bindOnInit to false) to bind/unbind the server socket during start/stop, close the socket earlier in the stop process so new connections do not sit in the TCP backlog during the shutdown process only to be dropped as stop completes. In this scenario new connections will now be refused immediately. (markt)

Jasper
Fix: 53011: When pre-compiling with JspC, report all compilation errors rather than stopping after the first error. A new option -failFast can be used to restore the previous behaviour of stopping after the first error. Based on a patch provided by Marc Pompl. (markt)
Add: 53492: Make the Java file generation process multi-threaded. By default, one thread will be used per core. Based on a patch by Dan Fabulich. (markt)
Add: 62453: Add a performance optimisation for using expressions in tags that depend on uninitialised tag attributes with implied scope. Generally, using an explicit scope with tag attributes in EL is the best way to avoid various potential performance issues. (markt)
Fix: Correctly decode URL paths (+ should not be decoded to a space in the path) in the Jasper class loader. (markt)
Fix: 62603: Fix a potential race condition when development mode is disabled and background compilation checks are enabled. It was possible that some updates would not take effect and/or ClassNotFoundExceptions would occur. (markt)

Fix: 61229: Correct a regression in 8.5.15 that broke WebDAV handling for resources with names that included a & character. (markt)
Coyote
Fix: Restore the ability to configure support for SSLv3. Enabling this protocol will trigger a warning in the logs since it is known to be insecure. (markt)
Fix: Do not log a warning when a null session is returned for an OpenSSL based TLS session since this is expected when session tickets are enabled. (markt)

Fix: Review those places where Tomcat re-encodes a URI or URI component and ensure that that correct encoding (path differs from query string) is applied and that the encoding is applied consistently. (markt)
Fix: Avoid a NullPointerException when reading attributes for a initialised HTTP connector where TLS is enabled. (markt)
Fix: Always quote the hostName of an SSLHostConfig element when using it as part of the JMX object name to avoid errors that prevent the associated TLS connector from starting if a wild card hostName is configured (because * is a reserved character for JMX object names). (markt)
Code: Start to switch to using Charset rather than String to store encoding configuration settings to reduce the number of places the associated Charset needs to be looked up. (markt)
Fix: Use a more reliable mechanism for the DefaultServlet when determining if the current request is for custom error page or not. (markt)
Fix: Ensure that when the Default or WebDAV servlets process an error dispatch that the error resource is processed via the doGet() method irrespective of the method used for the original request that triggered the error. (markt)
Fix: If a static custom error page is specified that does not exist or cannot be read, ensure that the intended error status is returned rather than a 404 or 403. (markt)
Fix: When the WebDAV servlet is configured and an error dispatch is made to a custom error page located below WEB-INF, ensure that the target error page is displayed rather than a 404 response. (markt)

Fix: 60940: Improve the handling of the META-INF/ and META-INF/MANIFEST.MF entries for Jar files located in /WEB-INF/lib when running a web application from a packed WAR file. (markt)
Fix: Pre-load the ExceptionUtils class. Since the class is used extensively in error handling, it is prudent to pre-load it to avoid any failure to load this class masking the true problem during error handling. (markt)
Fix: Avoid potential NullPointerExceptions related to access logging during shutdown, some of which have been observed when running the unit tests. (markt)
Fix: When there is no javax.servlet.WriteListener registered then a call to javax.servlet.ServletOutputStream#isReady will return false instead of throwing IllegalStateException. (violetagg)
