+ndn-cxx version 0.9.0
+---------------------
+
+*Release date: July 28, 2024*
+
+Important changes and new features
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- **C++17** is now *required* to build ndn-cxx and when including any of its header files
+
+- The build dependencies have been increased as follows:
+
+  - GCC >= 9.3 or Clang >= 7.0 are strongly *recommended* on Linux; GCC 8.x is also known
+    to work but is not officially supported
+  - Xcode 13 or later is *recommended* on macOS; older versions may still work but are not
+    officially supported
+  - Boost >= 1.71.0 is *required* on all platforms
+
+- Ubuntu 24.04 (Noble), Debian 12 (Bookworm), and macOS 14 (Sonoma) are now officially supported
+
+- Added an official Dockerfile to the repository. From this Dockerfile, two images are currently
+  published to the GitHub container registry:
+
+  - `named-data/ndn-cxx-build <https://github.com/named-data/ndn-cxx/pkgs/container/ndn-cxx-build>`__
+  - `named-data/ndn-cxx-runtime <https://github.com/named-data/ndn-cxx/pkgs/container/ndn-cxx-runtime>`__
+
+  Both images are available for *linux/amd64* and *linux/arm64* platforms.
+
+- The default forwarder socket path for Unix transports changed to ``/run/nfd/nfd.sock`` on Linux
+  and to ``/var/run/nfd/nfd.sock`` on all other platforms (:issue:`5304`)
+
+- On macOS, the default TPM backend is now **tpm-file** (the same as all other platforms)
+
+- :ndn-cxx:`Interest::matchesData` no longer considers ``MustBeFresh`` and ``FreshnessPeriod``
+  (:issue:`5270`)
+
+- Modernized several APIs to use ``std::string_view``
+
+- Added :ndn-cxx:`Interest::setApplicationParameters(std::string_view)` and
+  :ndn-cxx:`Data::setContent(std::string_view)` overloads for convenience
+
+- :ndn-cxx:`SegmentFetcher` gained an option to omit ``MustBeFresh`` from the first Interest sent
+
+- Moved :ndn-cxx:`DummyClientFace`, :ndn-cxx:`Segmenter`, and :ndn-cxx:`SegmentFetcher` to
+  namespace ``ndn``
+
+- Moved all :ndn-cxx:`Signal`-related classes to namespace ``ndn::signal``
+
+Improvements and bug fixes
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- Check the TLV type when constructing :ndn-cxx:`Name` from :ndn-cxx:`Block`
+
+- Provide relational operators for :ndn-cxx:`FaceUri`, to make it usable as a container key
+
+- Generalize and simplify :ndn-cxx:`time::fromUnixTimestamp` and :ndn-cxx:`time::toUnixTimestamp`
+
+- Prevent overflows in ``InterestLifetime`` and ``FreshnessPeriod`` (:issue:`4997`)
+
+- Make HMAC signing and verification compatible with OpenSSL 3.x (:issue:`5251`)
+
+- Better handling of large dates in :ndn-cxx:`ValidityPeriod` (:issue:`5176`)
+
+- :ndn-cxx:`NetworkMonitor` now ignore AWDL interfaces on macOS (:issue:`5074`)
+
+- Avoid dependency on *boost_program_options* when tools are disabled (:issue:`5210`)
+
+- Add fine-grained options to ``./waf configure`` to enable/disable the compilation of
+  benchmarks, integration tests, and unit tests independently
+
+- Fix building the documentation with Python 3.12 (:issue:`5298`)
+
+- Reduce amount of debugging information produced in compiled binaries by default (:issue:`5279`)
+
+- Update waf build system to version 2.0.27
+
+- Various code cleanups, modernizations, and documentation improvements
+
+Deprecations
+^^^^^^^^^^^^
+
+- ``Face::getIoService()``. Use ``Face::getIoContext()`` instead.
+
+- ``Component::fromEscapedString()``. Use :ndn-cxx:`Component::fromUri` instead.
+
+- TPM unlock and related functionality. This includes ``Tpm::isTpmLocked()``,
+  ``Tpm::unlockTpm()``, ``Tpm::isTerminalMode()``, ``Tpm::setTerminalMode()``,
+  and the ``ndnsec-unlock-tpm`` command-line tool (:issue:`4754`)
+
+Removals
+^^^^^^^^
+
+- ``Block::wire()``. Use :ndn-cxx:`Block::data` instead.
+
+- :ndn-cxx:`Component` constructors that take a raw ``const uint8_t*``. Use the ``span``-based
+  constructors instead.
+
+- ``Component::fromImplicitSha256Digest()`` and ``Component::fromParametersSha256Digest()``
+
+- Previously deprecated overloads of ``Name::append()``
+
+- ``Name::push_back()``. Use :ndn-cxx:`Name::append` instead.
+
+- ``ndn::escape()`` and ``ndn::unescape()`` overloads that take raw strings as ``const char*`` +
+  ``size_t``. Use the corresponding ``std::string_view`` versions instead.
+
+- ``ndn::optional`` and ``ndn::variant``. Use C++17 ``std::optional`` and ``std::variant``
+  directly instead.
+
+- ``ndn::to_string()``. Use the standard C++ function ``std::to_string()`` instead.
+
+- Previously deprecated ``ndnsec`` command aliases (:issue:`5163`)
