- Improve the sanitation of input data so that upper limits of extensive properties are not eliminated from the quantities to be fitted when upper limits are activated. (Médéric Boquien)

- Ensure that the radio module still works with recent versions of numpy. (Médéric Boquien & Laure Ciesla, reported by Wenjia Zhou)

- The unphysical wavy structure of the nebular continuum in the mid-infrared has been eliminated. (Médéric Boquien)

- The percentage of models with a low reduced χ² was too small by a factor 100. (Médéric Boquien, reported by Guang Yang)

### Optimised

- Slight speedup of the computation of the likelihood from the χ² using a multiplication rather than a division. (Médéric Boquien)

- Speedup of the computation of the χ² by ~10% taking the opposite of a scalar rather than of an array. (Médéric Boquien)
