Sparrow Wallet v2.0.0: SLIP39 Shares Recovery, New Hardware Wallets & More

• "This major version release includes an upgrade to Java and JavaFX 22, which means minimum system requirements have been updated to macOS 11 and GTK3 (macOS 10.15 has now been end of life for over 2 years). These upgrades fix issues on modern operating systems and prepare for future capabilities," said the developer.

"As part of this update, the Windows installer has been changed from .exe to .msi (Microsoft Installer format), but otherwise the installation process is unchanged from previous versions."

• Other release highlights include support for the Trezor Safe 5, Ledger Stax and Ledger Flex hardware wallets. Besides, Sparrow now supports recovering SLIP39 mnemonic shares to a hot wallet (via File > New Wallet > Software Wallet).
• Other notable improvements include saving a file for airgapped message signing, adding any missing previous outputs to a loaded PSBT, a number of warning dialogs to prevent user errors, and performance improvements, said the developer.
