# Release 3.3.2 - (December 21, 2018) * Fix Qt history export bug * Improve network timeouts # Release 3.3.1 - (December 20, 2018) * Qt: Fix invoices tab crash (#4941) * Android: Minor GUI improvements # Release 3.3.0 - Hodler's Edition (December 19, 2018) * The network layer has been rewritten using asyncio and aiorpcx. In addition to easier maintenance, this makes the client more robust against misbehaving servers. * The minimum python version was increased to 3.6 * The blockchain headers and fork handling logic has been generalized. Clients by default now follow chain based on most work, not length. * New wallet creation defaults to native segwit (bech32). * Segwit 2FA: TrustedCoin now supports native segwit p2wsh two-factor wallets. * RBF batching (opt-in): If the wallet has an unconfirmed RBF transaction, new payments will be added to that transaction, instead of creating new transactions. * MacOS: support QR code scanner in binaries. * Android APK: - build using Google NDK instead of Crystax NDK - target API 28 - do not use external storage (previously for block headers) * hardware wallets: - Coldcard now supports spending from p2wpkh-p2sh, fixed p2pkh signing for fw 1.1.0 - Archos Safe-T mini: fix #4726 signing issue - KeepKey: full segwit support - Trezor: refactoring and compat with python-trezor 0.11 - Digital BitBox: support firmware v5.0.0 * fix bitcoin URI handling when app already running (#4796) * Qt listings rewritten: the History tab now uses QAbstractItemModel, the other tabs use QStandardItemModel. Performance should be better for large wallets. * Several other minor bugfixes and usability improvements.
