+.BR v3.1.4\~ "released September 20, 2023"
+Version 3.1.4 fixes a minor bug, eliminates compilation warnings and
+static analysis warnings, and improves code:
+
+- fix: add checks to prevent silent overflow of short unsigned integers,
+
+- fix: compilation warnings with GCC 13 and clang 18,
+
+- fix: 1,040 clang-tidy warnings (from 3,669 warnings, down to 2,629),
+
+- improve: code modernization for long-term maintenance,
+
+- improve: double the maximal number of threads (from 256 threads to 512),
+
+- improve: make `-DNDEBUG` the default compilation behavior,
+performance: stable for all modes, except a 6 to 10% increase in memory footprint when d > 2.

 .BR v3.1.3\~ "released December 5, 2022"
 Version 3.1.3 fixes a few minor bugs, removes warnings, and improves code and documentation:
-fix: bug introduced in version 3.1.1, that caused swarm to allocate way too much memory when d > 1 (bug had no impact on clustering results),
-fix: off-by-one error when allocating memory for a Bloom filter (bug had no impact on clustering results),
-fix: compilation warning with GCC 12 (and more recent) when using link-time optimization,
-fix: compilation warning with clang 13 (and more recent): unused set variable,
-fix: five clang-tidy warnings (readability-braces-around-statements),
-fix: minor code refactoring,
-improve: more uniform vocabulary throughout swarm's documentation (code, help, manpage, README, companion scripts and wiki),
-improve: code coverage of our test suite (swarm-tests).
