 ### Changed
 - `INSAR_ISCE_BURST` now accepts `reference` and `secondary` parameters, each of which is a list containing a single granule name. In a future release, `INSAR_ISCE_BURST` will support processing multiple adjacent bursts into one interferogram, and each parameter will be a list of one or more granule names.
+- All previous `INSAR_ISCE_BURST` jobs have been reformatted to replace the `granules` parameter with the `reference` and `secondary` parameters.
 
 ### Removed
 - `INSAR_ISCE_BURST` no longer accepts a `granules` parameter.
