${{\boldsymbol \psi}{(4230)}}$ $I^G(J^{PC})$ = $0^-(1^{- -})$ 

also known as ${{\mathit Y}{(4230)}}$; was ${{\mathit X}{(4230)}}$
The recent measurement of ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \pi}}{{\mathit \pi}}$ (ABLIKIM 2017B) led to a downward shift in the mass of the ${{\mathit \psi}{(4260)}}$, also known as Y(4260), such that a distinction between the ${{\mathit \psi}{(4260)}}$ and ${{\mathit \psi}{(4230)}}$ no longer appears justified. Therefore, starting from this edition, we include the data of ABLIKIM 2017B in this node and have listed the ${{\mathit \psi}{(4230)}}$ in the summary tables instead of the ${{\mathit \psi}{(4260)}}$.
