dc.description.abstract© 2021 American Physical Society.We present an update of the event generator based on the three-fluid dynamics (3fd), complemented by Ultrarelativistic Quantum Molecular Dynamics (urqmd) for the late stage of the nuclear collision - the Three-fluid Hydrodynamics-based Event Simulator Extended by urqmd final State interactions (theseus). Two modifications are introduced. The theseus table of hadronic resonances is made consistent with that of the underlying 3fd model. The main modification is that the generator is extended to simulate the light-nuclei production in relativistic heavy-ion collisions, on an equal basis with hadrons. These modifications are illustrated by applications to the description of available experimental data. The first run of the updated generator revealed a good reproduction of the NA49 data on the light nuclei. The reproduction is achieved without any extra parameters, while the coalescence approach in 3fd requires special tuning of the coalescence coefficients for each light nucleus separately.
