 - Add explosions for 5e.
 - Movement power improvements for 5e (pointing, description, and added gliding).
 - Description improvements for invisibility and darkness. [#573](https://github.com/dmdorman/hero6e-foundryvtt/issues/573)
+- Correct a crash during the start of each segment for characters that have endurance powers active but with no power modifiers. Consequently, automatic endurance tracking should be be better.
 - Improvements to adjustment powers (although we suggest still only using them for characteristics):
   - Adjustment powers should now respect uploaded multi sources and targets when triggering. They should also respect maximum amounts for absorption, aid, and transfer for 5e and 6e.
   - No adjustment powers should be killing attacks that are enhanced by strength.

 - Changing PC/NPC actor type moved to sheet header.  Also can be changed in the context menu of the actor sidebar. Fixes [#170](https://github.com/dmdorman/hero6e-foundryvtt/issues/170).
-- Combat Tracker Improvments. Reworked underlying code so that _onEndRound and _onStartTurn are called as expected.  This should lead to future automation improvments.  For example Post-Segment-12 activities and Endurance use at the beginning of turn for continuous powers. Also changed tooltips for PREV/NEXT to align with Hero terminology.
