Feb. 2022: The upper limit of the unresolved resonance parameter of Pr-141 was inconsistent with that of unresolved resonance region. Fixed in update 1 (upd-1) on Feb. 16.
Corrected data (upd-1): n_059-Pr-141_u20.dat.gz

Jan. 2023: The inelastic scattering cross sections of MF10 for isomeric targets were inconsistent with those of MF3. Fixed in update 10 (upd-10).
Corrected data (upd-10): jendl5-n_upd10_u20.tar.gz

Jan. 2023: Production cross section of non-existent isomeric state in Ti-48 was given. Fixed in update 11 (upd-11).
Corrected data (upd-11): jendl5-n_upd11_u20.tar.gz

Aug. 2023: The data in MF8 were inconsistent with those in the other MF. Fixed in update 12 (upd-12).
