+NLSR version 0.7.0
+------------------
+
+Release date: August 18, 2023
+
+New features
+^^^^^^^^^^^^
+
+- Add experimental support for State Vector Sync (SVS) (:issue:`5248`)
+- ``nlsrc``: Add an option to query the status from remote routers (:issue:`4544`)
+
+Notable changes and improvements
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- **Deprecate ChronoSync support**: ChronoSync support is now optional and excluded from the
+ default build; it remains available mainly for testing purposes (:issue:`5147`)
+- Switched to the C++17 standard
+- 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
+
+- Refactor LSDB for readability and add signals to notify of modifications (:issue:`4127`)
+- Retrieve LSA from the face that triggered the notification of LSA changes
+- Accommodate certificate name in ``KeyLocator`` (:issue:`5195`)
+- Change ``sig-type`` to ``ecdsa-sha256`` in ``nlsr.conf`` as ndn-cxx now has strict checking for it
+- Improve error handling and reporting
+- Stop using the ``gold`` linker on Linux; prefer instead linking with ``lld`` if installed
+- Update waf build system to version 2.0.24
+- Various test suite and documentation improvements
+
+Bug fixes
+^^^^^^^^^
+
+- lsdb: Fix for issues involving incorrect retransmission behavior in segment fetcher
+- Prevent NLSR from unregistering route during update for router that advertised it initially
+ (:issue:`5179`)
+- NameLsa: fix LSDB update bug by sorting the NPLs before difference
+- Fix recurring sync prefix registration on every hello data (:issue:`5157`)
+- Return the appropriate exit codes when executing ``nlsrc`` advertise/withdraw commands
+ (:issue:`5271`)
