 Varnish Cache 7.3.1 (2023-11-07)
 ================================
 
-* The ``vcl_req_reset`` feature (controllable through the ``feature``
-  parameter, see `varnishd(1)`) has been added and enabled by default
-  to terminate client side VCL processing early when the client is
-  gone.
-
-  *req_reset* events trigger a VCL failure and are reported to
-  `vsl(7)` as ``Timestamp: Reset`` and accounted to ``main.req_reset``
-  in `vsc` as visible through ``varnishstat(1)``.
-
-  In particular, this feature is used to reduce resource consumption
-  of HTTP/2 "rapid reset" attacks (see below).
-
-  Note, in particular, that *req_reset* events may lead to client
-  tasks for which no VCL is called ever. Presumably, this is thus the
-  first time that valid `vcl(7)` client transactions may not contain
-  any ``VCL_call`` records.
-
 * Added mitigation options and visibility for HTTP/2 "rapid reset"
   attacks (CVE-2023-44487_, 3996_, 3997_, 3998_, 3999_).

-* The ``cli_limit`` parameter default has been increased from 48KB to
-  64KB.
+* A race condition has been fixed in the backend probe code which
+  could trigger a panic with dynamic backends (dyn100_).
 
-* ``VSUB_closefrom()`` now falls back to the base implementation not
-  only if ``close_range()`` was determined to be unusable at compile
-  time, but also at run time. That is to say, even if
-  ``close_range()`` is compiled in, the fallback to the naive
-  implementation remains.
+* A bug has been fixed in the ESI code which would prevent use of
+  internal status codes >1000 as their modulus 1000 value (3958_).
 
-* Fixed ``varnishd -I`` error reporting when a final newline or
-  carriage return is missing in the CLI command file (3995_).
+* Fixed a performance issue in http/2 upload processing (3930_).
 
-* Improved and updated the build system with respect to autoconf and
-  automake.
+* A regression introduced with Varnish Cache 7.3.0 was fixed: On
+  HTTP/2 connections, URLs starting with ``//`` no longer trigger a
+  protocol error (3911_).
 
-* Improved ``VSB_tofile()`` error reporting, added support for partial
-  writes and support of VSBs larger than INT_MAX.
+* A bug has been fixed where ``unset bereq.body`` had no effect when
+  used with a cached body (3914_).
+
+* Fixed a compatibility issue in the abstract socket support (3908_).
 
 * Improved HPACK header validation.
 
-* Fixed scopes of protected headers (3984_).
+* HTTP/2 header field validation is now more strict with respect to
+  allowed characters (3952_).
