The next version of the MetaTrader 5 platform was released by MetaQuotes yesterday - Build 3661. It is already available from MT5 brokers via their automatic update facility. It fixes the notorious code generation error introduced in the MT5 Build 3660, which had been released a few days earlier and fixed a bug with platform log creation and MQL5's handling of global variables.
