The latest version of JENDL general purpose file, i.e. JENDL-4.0 was released in 2010. It focused on improvements of the data of fission products and minor actinides that would be important for research and development on light water reactors with high burn-up and MOX fuels, and also for innovative reactors such as ones for accelerator driven system. After that, many special purpose files have been released: JENDL FP Decay Data File 2011 (JENDL/FPD-2011), JENDL FP Fission Yields Data File 2011 (JENDL/FPY-2011), JENDL-4.0 High Energy File (JENDL-4.0/HE), JENDL Decay Data File 2015 (JENDL/DDF-20215), JENDL Photonuclear Data File 2016 (JENDL/PD-2016), JENDL Activation Cross Section File for Nuclear Decommissioning 2017 (JENDL/AD-2017), JENDL LLFP Transmutation Cross Section File 2018 (JENDL/ImPACT-2018). These files were developed to meets needs from expanding fields of applications such as backends of nuclear energy and accelerator utilizations. In addition to the special purpose files, development of the next version of general purpose file JENDL-5 is in progress. For JENDL-5, we are aiming at increasing completeness and reliability from JENDL-4.0 in viewpoints of target nuclide species and data uncertainties by taking into accounts the current knowledge of cross section measurements, nuclear theory and integral benchmark tests. A new R-matrix theory code AMUR has been developed and applied to the resonance analysis for light nuclides. Structure materials and medium-heavy nuclides have been evaluated using the modern nuclear reaction model codes CCONE. Minor actinides data was updated using the TOF measurements with ANNRI installed at MLF in J-PARC. The first test library JENDL-5$\alpha$1 was created last year and its integral benchmark tests was performed. The next version of the test files JENDL-5$\alpha$2 will be made in this year. JENDL-5 is planned to be released in 2022. At the symposium, progress and future plan of JENDL-5 and summary of the recently released special purpose files will be presented.
