Changes in this release: - Added Vertcoin support. - Switched to 'btc-fee.net' for more aggressive BTC fee estimation to avoid overpaying. - Renamed miner fee selection labels from 'Fast', 'Medium', 'Slow' to 'Priority', 'Normal', 'Economy' respectively. - Added extra fee option 'Frugal' for BTC transactions which always uses 1 sat/byte miner fee. Be careful when using this; Only use this if you know the network isn't congested otherwise the transaction may not confirm for a long time. - Fixed console.log of host<-->device message consistency. - Fixed device connectivity issue where sometimes KeepKey doesn't get detected when plugged in. - Fixed style wrapping issue for long digit balances. - Made 'Receive Address' more robust in handling PIN timeouts. - Reworked the PIN retry mechanism so it works correctly in other contexts besides device initialization. - Expose 'EndSession' method for 'DeviceBridge'. This is handy for allowing user to directly clear PIN caching from dev console with KeepKey.DeviceBridge.endSession(). - Implemented BIP39 mnemonic length selection during KeepKey initialization. User can now select between 12, 18 or 24 words when generating mnemonic phrase on KeepKey. - Allow PIN input from keyboard numpad when setting and confirming new PIN. - Removed Shapeshift advert overlay during loading. - Added atomicwallet blockbook indexers for some of the coins. - UI visual fix: Grey out PIN input button until at least 1 digit is entered. This sidesteps an error with 0 length PIN input.
