 ### Changed behavior
 
 * (core) `EmpiricalRandomVariable` CDF pairs can now be added in any order.
+* (core) `EmpiricalRandomVariable` no longer requires that a CDF pair with a range value exactly equal to 1.0 be added (see issue #922).
 * (wifi) Upon ML setup, a non-AP MLD updates the IDs of the setup links to match the IDs used by the AP MLD.
 * (wifi) Attribute **TrackSignalsFromInactiveInterfaces** in SpectrumWifiPhy has been defaulted to be enabled.

 ### Bugs fixed
 
+- (core) #922 - `EmpiricalRandomVariable` no longer requires that a CDF pair with a range value exactly equal to 1.0 be added.
 - (lr-wpan) - !1591 - Removed unnecessary Bcst filter from MAC
 - (wifi) - Reset MU PPDU UID to prevent STA from receiving the TB PPDU sent by another STA
 - (wifi) - Fix max value for UL MCS field of User Info fields (depends on TF variant)
