New version 5.2.21.0 has been released on 10th September 2016.
It includes changes to prepare for Betfair's forthcoming migration of AU and NZ markets onto the UK exchange.
Betfair are planning to retire the separate Australian exchange on 20th September 2016 and migrate all AU and NZ markets to the main Main/UK exchange. Funds held in AUS wallets, will be transferred to the Main/UK wallets. So thereafter, all markets will be operated on the same exchange and there will be just one wallet for all markets, regardless of the country.
Kind regards,
Gavin
