-Unreleased — 2.24
+2024-02-15 — 2.24
 
 * The documentation now specifies the acceptable range for orbital
   element angles like inclination and mean anomaly, and a new function
   ``check_satrec(sat)`` will tell the caller if any of the angles are
   out of bounds.
 
+* The documentation now gives an example of loading elements from JSON.
+
 * Tweaked the fallback Python code to accept TLE lines without a final
   checksum character in the 69th column, to match the C++ code.
