+PSync version 0.4.0
+-------------------
+
+*Release date: January 18, 2023*
+
+Important changes and new features
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- The minimum build requirements have been increased as follows:
+
+  - Either GCC >= 7.4.0 or Clang >= 6.0 is required on Linux
+  - On macOS, Xcode 11.3 or later is recommended; older versions may still work but are not
+    officially supported
+  - Boost >= 1.65.1 and ndn-cxx >= 0.8.1 are required on all platforms
+  - Sphinx 4.0 or later is required to build the documentation
+
+- *(breaking change)* Switch to C++17
+- *(breaking change)* The Name TLV value is now hashed directly instead of being converted
+  to URI format first (:issue:`4838`)
+- Add ``incomingFace`` field to missing data notifications (:issue:`3626`)
+- *(breaking change)* Add ``ndn::KeyChain`` parameter to the producer API
+- Provide API to remove a subscription in partial sync :psync:`Consumer` (:issue:`5242`)
+
+Improvements and bug fixes
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- Use ndn-cxx's ``ndn::util::Segmenter`` class in :psync:`SegmentPublisher`
+- Fix compilation against the latest version of ndn-cxx
+- Stop using the ``gold`` linker on Linux; prefer instead linking with ``lld`` if installed
+- Update waf build system to version 2.0.24
+- Various documentation improvements
+
+Known issues
+^^^^^^^^^^^^
+
+- We have taken some steps to be endian safe but PSync is not completely endian safe yet
+  (:issue:`4818`)
