     Apache HTTP Server 2.4.65 and earlier with Server Side Includes
     (SSI) enabled and mod_cgid (but not mod_cgi) passes the
     shell-escaped query string to #exec cmd="..." directives.
     This issue affects Apache HTTP Server before 2.4.66.

  *) SECURITY: CVE-2025-55753: Apache HTTP Server: mod_md (ACME),
     unintended retry intervals (cve.mitre.org)
     An integer overflow in the case of failed ACME certificate
     renewal leads, after a number of failures (~30 days in default
     configurations), to the backoff timer becoming 0. Attempts to
     renew the certificate then are repeated without delays until it
     succeeds.
     This issue affects Apache HTTP Server: from 2.4.30 before 2.4.66.
     Users are recommended to upgrade to version 2.4.66, which fixes
     the issue.

  *) mod_http2: Fix handling of 304 responses from mod_cache. PR 69580.
     [Stefan Eissing]

  *) mod_http2/mod_proxy_http2: fix a bug in calculating the log2 value of
     integers, used in push diaries and proxy window size calculations.
     PR69741 [Benjamin P. Kallus]

  *) mod_md: update to version 2.6.5
     - New directive `MDInitialDelay`, controlling how longer to wait after
       a server restart before checking certificates for renewal.
       [Michael Kaufmann]
     - Hardening: when build with OpenSSL older than 1.0.2 or old libressl
       versions, the parsing of ASN.1 time strings did not do a length check.
     - Hardening: when reading back OCSP responses stored in the local JSON
       store, missing 'valid' key led to uninitialized values, resulting in
       wrong refresh behaviour.

  *) mod_md: update to version 2.6.6
     - Fix a small memory leak when using OpenSSL's BIGNUMs. [Theo Buehler]
     - Fix reuse of curl easy handles by resetting them. [Michael Kaufmann]

  *) mod_http2: update to version 2.0.35
     New directive `H2MaxStreamErrors` to control how much bad behaviour
     by clients is tolerated before the connection is closed.
     [Stefan Eissing]

  * mod_proxy_http2: add support for ProxyErrorOverride directive. PR69771

  *) mpm_common: Add new ListenTCPDeferAccept directive that allows to specify
     the value set for the TCP_DEFER_ACCEPT socket option on listen sockets.
     [Ruediger Pluem]

  *) mod_ssl: Add SSLVHostSNIPolicy directive to control the virtual
     host compatibility policy.  PR 69743.  [Joe Orton]

  *) mod_md: update to version 2.6.2
     - Fix error retry delay calculation to not already doubling the wait
       on the first error.

  *) mod_md: update to version 2.6.1
     - Increasing default `MDRetryDelay` to 30 seconds to generate less bursty
       traffic on errored renewals for the ACME CA. This leads to error retries
        of 30s, 1 minute, 2, 4, etc. up to daily attempts.
     - Checking that configuring `MDRetryDelay` will result in a positive
       duration. A delay of 0 is not accepted.
     - Fix a bug in checking Content-Type of responses from the ACME server.
     - Added ACME ARI support (rfc9773) to the module. Enabled by default. New
       directive "MDRenewViaARI on|off" for controlling this.
     - Removing tailscale support. It has not been working for a long time
       as the company decided to change their APIs. Away with the dead code,
       documentation and tests.
     - Fixed a compilation issue with pre-industrial versions of libcurl.
