  Since its inception, the full Lagrangian meshless smoothed particle
hydrodynamics (SPH) method has experienced a tremendous enhancement in
methodology and impacted a range of multi-physics applications in science and
engineering.
  The paper presents a concise review on latest developments and achievements
of the SPH method, including (1) brief review of theory and fundamental with
kernel corrections,
  (2) the Riemann-based SPH method with dissipation limiting and high-order
data reconstruction by using MUSCL, WENO and MOOD schemes,
  (3) particle neighbor searching with particle sorting and efficient
dual-criteria time stepping schemes,
  (4) total Lagrangian formulation with stablized, dynamics relaxation and
hourglass control schemes,
  (5) fluid-structure interaction scheme with interface treatments and
multi-resolution discretizations,
  (6) novel applications of particle relaxation for mesh and particle
generations.
  Last but not least, benchmark tests for validating computational accuracy,
convergence, robustness and efficiency are also supplied accordingly.
