The latest version of the general purpose file JENDL-4.0 was released in 2010 with enhancing data of fission products and minor actinides. After that, the neutron energy range of JENDL-4.0 were extended up to 200 MeV adding proton induced reaction data. They were compiled as JENDL-4.0/HE and released in 2015. An activation cross section library for decommission of nuclear reactor, JENDL/AD-2016, is under development and will be released by 2017. It will contain neutron reaction data for approximately 300 nuclides in energy range of $$10^{-5}$$ eV to 20 MeV including isomer production cross sections. Evaluation of nuclear data for the next version of the general purpose file is also in progress. It is planned to be released by 2022. Several new evaluations mainly for fission products that had not been updated in JENDL-4.0 were already done. Data for light nuclei and structure material will be updated. Minor actinides data are still important to develop transmutation system of nuclear waste. They will be updated using new measurements especially done in J-PARC. Status of the JENDL project in developing the general and special purpose files will be presented.
