•The Load Shedding module starts even when there are Reactors or Capacitors disconnected from the network. This bug occurred since v4.7.129.

•Fixed a behavior in the Self-Healing module where I/O failures in *SwitchPosition Discrete Measurements compromise a search for solutions. This bug occurred since v4.7.276.

•Fixed an error in the State Estimator module, which presented different outputs for the same input depending on the previous inputs. This bug occurred since v4.7.119.

•Fixed an error in the Self-Healing module, which ignored protection measures in phases other than the ones where devices were connected. This bug occurred since v4.7.119.

•Triggers with bad quality now are registered on the events database with a -28 code. This bug occurred since v4.7.167.

•The Self-Healing module memorizes values of Measurements disabled or configured with the StudyInputSource property equal to None. This bug occurred since v4.7.119.

•Switches without a SelfHealing Source in the *SwitchPosition Discrete Measurement are not considered as a trigger option anymore by the Self-Healing module. This bug occurred since v4.7.119.

•Fixed an error in the Self-Healing module, which could find solutions with overload if the trigger plan involved transferring Loads to Switches with different levels of voltage. This bug occurred since v4.7.119.

•The Self-Healing module does not generate empty steps anymore for Switches without any output Measurement (DevicesUpstream, DevicesDownstream, or ExpectedCurrent). This bug occurred since v4.8.89.

•Fixed an error in the Self-Healing module, which presented a sub-optimal solution due to an incorrect selection of Switches adjacent to the problem. This bug occurred since v4.7.119.

•Fixed power and current values in the Terminal three of a Three-Winding Transformer. This bug occurred since v4.7.156.

•The Self-Healing module returns the value SelfHealingResultInconsistentTopologyState when a Switch with a trigger does not have a good path for the Generator. This bug occurred since v4.7.119.

•The log "Trigger upstream switch(es) are" does not show Switches with bad quality anymore. This bug occurred since v4.7.119.

•The Self-Healing module returns an error code if the trigger starts in a de-energized Recloser. This bug occurred since v4.8.277.

•Fixed the impedance calculation of a Three-Winding Transformer in the State Estimator module. This bug occurred since v4.7.119.

•The Self-Healing module returns the error code SelfHealingResultProtectionDisabled if the restoration trigger starts in Switches that are isolated, in by-pass, or in switch mode. This bug occurred since v4.8.163.

•Closing the PowerEngine2 library with a Topological Processor is now much more faster in large systems. This bug occurred since v4.7.119.

•The current injected by a bank of Capacitors does not prevent triggering the Self-Healing module anymore. This bug occurred since v4.7.119.

•Fixed a failure when executing a trigger plan of a restoration trigger, which occurred when the solution involved closing that trigger's Switch. This bug occurred since v4.8.85.

•Fixed the solution for restoration triggers, where Reclosers in switch mode behave as protection elements if they were not immediately downstream of that trigger. This bug occurred since v4.7.119.
