Following the main objective of the IAEA Coordinated Research Project on Photonuclear Data and Photon Strength Functions (Code F41032; Duration 2016-2019), new measurements of photoneutron and photofission cross sections in the Giant Dipole Resonance energy region have been performed at the laser Compton-scattering $\gamma$-ray source of the NewSUBARU synchrotron radiation facility. Nuclei in a wide mass range spanning from $^9$Be to $^{238}$U have been investigated. Quasi-monochromatic $\gamma$-ray beams with typical energy resolution 3% in FWHM have been employed. The neutron multiplicity sorting has been performed using an energy-dependent statistical treatment of neutron coincidence events associated with a flat-efficiency moderated neutron detection array. We report updates on the experimental technique and methodology and selected experimental results on photoneutron ($^{197}$Au, $^{208}$Pb) and photofission ($^{232}$Th, $^{238}$U) cross sections as well as average energies of neutron emission spectra.
