    Changes for libtcnative-1-0:

    - Update to 1.3.9
     * Security fixes      + Client certificate requirements can be down-graded      (bsc#1282621, CVE-2026-86247)      A race condition allowed client certificate verification      requirements to be down-graded for some configurations.
     + Insecure OpenSSL options enabled (bsc#1282622, CVE-2026-86246)      Apache Tomcat Native enabled insecure options by default      including ALLOW_CLIENT_RENEGOTIATION,      NO_EXTENDED_MASTER_SECRET, IGNORE_UNEXPECTED_EOF and      ALLOW_NO_DHE_KEX.
     + DoS via TLS handshake (bsc#1282623, CVE-2026-86243)      A buffer over-read vulnerability in Apache Tomcat Native      during the TLS handshaking permits a malicious user to trigger      a DoS via a JVM crash.
     * Changes      + Code: Remove call to ERR_remove_thread_state() from Windows      specific code to allow building with OpenSSL 4.0.x.
     ERR_remove_thread_state() is a no-op in OpenSSL 1.1+ and got      removed in OpenSSL 4      + Fix: Fix a potential crash when negotiating ALPN      + If ALPN negotiation fails and failure is configured to use      the last server protocol in the list, use it rather than the      last protocol offered by the client      + Fix: Add support for the extended range of options available      from OpenSSL 3.0.x. The options flag is now a 64-bit unsigned      int (represented by a Java long) rather than a 32-bit unsigned      int (represented by a Java int)      + Code: Remove unused code      + Ensure that per connection changes to certificate verification      settings, e.g. to support client certificate authentication,      do not modify the certificate verification settings for other      connections      + Fix: Fix a potential crash when configuring raw certificates      + Fix: Avoid a potential crash with very long ALPN protocol      names      + Fix: Make the call to a CertificateVerifier more robust      + Fix: Avoid a potential crash when processing OCSP URLs      + Fix: Make the processing of OCSP responses more robust      + Fix: Stricter OCSP handling when soft-fail is disabled      + Fix: Harden against the mis-use of Buffer.address(ByteBuffer)      + Fix: Harden against the mis-use of Pool.destroy(long)      + Code: The minimum supported OpenSSL version is now 3.0.x.
     OpenSSL 1.1.1 support was accidentally broken in 1.3.8. As no      bug reports were receive for that failure and since both      Debian and Ubuntu versions that used OpenSSL 1.1.1 have      reached end of support, OpenSSL 1.1.1 is no longer supported      + Update: OpenSSL 3.0.x is approaching end of support so the      recommended version of OpenSSL (and the version that windows      binaries will be built with) now follows the 3.5.x LTS branch      + Fix: Switch to automatic configuration of DH parameters.
     Manual configuration attempts will be ignored      + Code: Make setTmpECDHByCurveName() a NO-OP      + Fix: Refactor extraction of ECDH curve name from the      Certificate to avoid deprecated OpenSSL methods      + Fix: Refactor the native implementation of SSL.getTime() to      avoid the Y2038 problem in SSL_SESSION_get_time() when running      on a verion of OpenSSL that includes the new      SSL_SESSION_get_time_ex() method

    Changes for tomcat:

    - Update to Tomcat 9.0.122
     * Catalina      + Fix: Improve the handling of AsyncContext.dispatch() when the Context      attribute dispatchersUseEncodedPaths is set to false since the      application has no control over the path used for the      AsyncContext.dispatch(). Prior to this fix, paths containing literal '?'      characters were truncated. (markt)      + Fix: Ensure that capture groups from a RewriteCond always reflect the      result of the current request. (markt)      + Fix: When a PersistentManager needs to reduce the number of active      sessions, swap out the least recently used eligible sessions first. Pull      request #1045 provided by sainadh777. (markt)      + Fix: Align web.xml logging output with the new Context attribute      urlPatternsProvidedInDecodedForm. (markt)      + Fix: Improve robustness of DIGEST authentication to system clock jumps.
     (markt)      + Add: Support multiple protocol header values (treat as a single merged      header value) in the RemoteIpFilter and RemoteIpValve. (markt)      + Fix: potential concurrency issues when loading/saving sessions from/to a      session store. Custom Store implementations that do not extend StoreBase      must implement the new getSessionStoreLock() method of the Store      interface to ensure concurrency protection. The default method      implementation provided only provides the pre-fix functionality. (markt)      + Fix: Ensure that PersistentManager implementations that extend      PersistentManagerBase do not swap out sessions that are associated with      a request that is currently being processed. As a result, it is now a      requirement that the system property      org.apache.catalina.session.StandardSession.ACTIVITY_CHECK is set to      true (either explicitly or via STRICT_SERVLET_COMPLIANCE) if either      minIdleSwap or maxIdleSwap are configured.

    Changes for tomcat10:

    - Update to Tomcat 10.1.60
     * Catalina      + Fix: When a PersistentManager needs to reduce the number of active      sessions, swap out the least recently used eligible sessions first. Pull      request #1045 provided by sainadh777. (markt)      + Fix: Align web.xml logging output with the new Context attribute      urlPatternsProvidedInDecodedForm. (markt)      + Fix: Improve robustness of DIGEST authentication to system clock jumps.
     (markt)      + Add: Support multiple protocol header values (treat as a single merged      header value) in the RemoteIpFilter and RemoteIpValve. (markt)      + Fix: potential concurrency issues when loading/saving sessions from/to a      session store. Custom Store implementations that do not extend StoreBase      must implement the new getSessionStoreLock() method of the Store      interface to ensure concurrency protection. The default method      implementation provided only provides the pre-fix functionality. (markt)      + Fix: Ensure that PersistentManager implementations that extend      PersistentManagerBase do not swap out sessions that are associated with      a request that is currently being processed. This includes not swapping      out a session unless the session was created when activity tracking was      enabled. (markt)      + Fix: Ensure namespace attributes are XML escaped in WebDAV responses.
     + Fix: Resolve null or missing rewrite substitutions as an empty string,      to align with the mod_rewrite behavior. (remm)      + Add: a best efforts protection in the CrawlerSessionManagerValve against      crawlers being associated with an authenticated session. (markt)      + Fix: Clarify the meaning of various RewriteValve server variables and      explicitly use the canonical context path for the CONTEXT_PATH server      variable. (markt)      + Fix: storeconfig not saving the path when a context is saved in      server.xml. (remm)      + Fix: WAR URLConnection should propagate use of caching. (remm)      + Fix: Ensure resources are evicted from the static resource cache in the      correct order. (markt)      + Fix: When Jakarta Authentication is configured for a web application,      cache the ServerAuthConfig in the Authenticator valve. This ensures web      application specific settings are cached on a per web application basis.
     + Fix: 70203: Fix RegistrationListener notifications in Jakarta      Authentication implementation. (markt)      + Fix: Handle CGI scripts that write excessively to stdout after setting      an HTTP error status code. (schultz)      + Fix: Require the request to the login action during FORM authentication      to be made using HTTP POST. (markt)      + Fix: 70208: Make URL encoding more robust. Based on pull request #1065      by Chenjp. (markt)
