 ### Changed
 - Moved the events -> TOAs and photon weights code into the function `load_events_weights` within `event_optimize`.
 - Updated the `maxMJD` argument in `event_optimize` to default to the current mjd
+- Changed default value of `FDJUMPLOG` to `Y`
 - Bumped `black` version to 24.x
 ### Added
 - Type hints in `pint.derived_quantities` and `pint.residuals`
