This table details a summary of the latest changes made to e-POP data files.
| Instrument | Product | Version | Date | Changes |
| Spacecraft | CAS Ephemeris txt | 1.2 | 2022-06-10 | Minor bug fix in calculation of geodetic latitude and altitude. Fixes errors on the order of 0.001 degrees latitude and 0.01 km altitude. |

| FAI | lv1 h5 | v5.0 | 2021-10-08 | – New format (hdf5) – Image data is now in units of Rayleighs – Files now include latitude and longitude of projection of image onto the Earth at 110 km (NIR) or 220 km (VIS) altitude – Updated ephemeris and attitude data – Now one file per pass rather than one file per image |
| GAP | lv1 binary | v2.0 | 2018-06-22 | – Filenames now have a major and minor version number – Data files are now split after two minutes of break rather than twenty – Fixed bug that caused minor loss of data at the end of some files |
