There's a minor Android one with a few Outlier-related bug fixes that's in beta channel now and will probably start rolling out to non-beta users today - that might be the one that
@Harionago downloaded. But we've basically done this within our existing database format - there'll be more app changes to accommodate this as they continue expanding the dictionary, but we wanted to make sure that a) users of old devices that weren't old devices when they backed the Kickstarter can still get the dictionary (system requirements are going to go up a lot in Pleco 4.0), and that b) we wouldn't be introducing any delay on our end due to App Review or whatever. (and also that c) we didn't waste a lot of time implementing things that they eventually decided not to do / to do very differently as the dictionary developed)
