Beta Version: 188.8.131.52 (released 2017-06-23)
Make sure you back up your wallet/seed before upgrading from an earlier version.
What's New since 184.108.40.206?
- Fixes for Trezor and Keepkey.
- Now compatible with newer versions of macOS.
- The wallet file format has been upgraded. This upgrade is not backward compatible, which means that a wallet upgraded to the 2.8 format will not be readable by earlier versions of Electrum. Multiple accounts inside the same wallet are not supported in the new format; the Qt GUI will propose to split any wallet that has several accounts. Make sure that you have saved your seed phrase before you upgrade Electrum.
- Support for the new Litecoin P2SH address version (multisig addresses now start with M). Old multisig wallets must be regenerated from seed to convert them to the new address type.
- Wallet file encryption using ECIES: A keypair is derived from the wallet password. Once the wallet is decrypted, only the public key is retained in memory, in order to save the encrypted file.
- Seed phrases can be extended with a user-chosen passphrase. The length of seed phrases is standardized to 12 words, using 132 bits of entropy. In the wizard, the type of the seed is displayed in the seed input dialog.
- Invoices and contacts are stored in the wallet file and are no longer shared between wallets. Previously created invoices and contacts files may be imported from the menu.
- This version introduces a separation between wallets types and keystores types. 'Wallet type' defines the type of Bitcoin contract used in the wallet, while 'keystore type' refers to the method used to store private keys. Therefore, so-called 'hardware wallets' will be referred to as 'hardware keystores'.
- Hardware keystores: The Ledger Nano S is supported.
- Hardware keystores: Support for Ledger firmwares older than version 1.0.1 has been dropped.
- Hardware keystores can be used as cosigners in multi-signature wallets. Multiple hardware cosigners can be used in the same multisig wallet. One icon per keystore is displayed in the satus bar. Each connected device will co-sign the transaction.
- The daemon requires wallets to be explicitly loaded before commands can use them. Wallets can be loaded using: electrum-ltc daemon load_wallet [-w path]. This command will require a password if the wallet is encrypted.
- Qt GUI: The Address tab is hidden by default, can be shown with Ctrl-A.
- Qt GUI: a blue icon is shown when connected using a proxy.
- SPV: add blockchain checkpoints, configurable by user.
- Support for Replace-By-Fee (RBF).
- Add Testnet support (--testnet option).
- Experimental support for Segregated Witness (testnet only).
