# Release 4.0 - (Not released yet; release notes are incomplete) |
|
|
|
# Release 4.0.0b0 - Codename? (June XX, 2020) |
|
|
|
|
|
|
|
* Experimental support for the Lightning Network |
|
|
|
- Lightning is disabled by default. It can be enabled, per-wallet, |
|
|
|
in the GUI, in Wallet>Information (or init_lightning cmd). Currently |
|
|
|
Lightning is restricted to HD p2wpkh wallets (including watch-only |
|
|
|
and hardware wallets). |
|
|
|
- LN protocol details: dataloss_protect and static_remotekey are |
|
|
|
required; varonion and payment_secret are implemented, MPP not yet. |
|
|
|
Channels are not announced ('private'), forwarding is disabled. |
|
|
|
The default 'to_self_delay' CSV is 1 week. |
|
|
|
- The Qt GUI, CLI/RPC, and the kivy GUI all have LN support, |
|
|
|
with feature-richness in that order. |
|
|
|
- Submarine swaps: the GUI integrates a service that offers |
|
|
|
atomically exchanging on-chain and lightning bitcoins for a fee. |
|
|
|
Electrum Technologies runs a central server for this, powered by |
|
|
|
the Boltz backend. |
|
|
|
- Static channel backups: a backup for each channel can be exported |
|
|
|
that can be used to trigger a remote-force-close. These are |
|
|
|
encrypted from a key derived from the wallet's xpub, and can |
|
|
|
be imported into another copy of the same wallet or a watch-only |
|
|
|
version of it. (the force close is not triggered automatically, |
|
|
|
imported backups can live inside a wallet file) |
|
|
|
- watchtowers? |
|
|
|
* Support Partially Signed Bitcoin Transactions (BIP-174) has been |
|
|
|
fully integrated. (#5721) The previously used custom partial tx |
|
|
|
format is removed, i.e. the partial transaction format has been |
|
|
|
incompatibly changed. Users should make sure that all instances of |
|
|
|
Electrum they use to co-sign or offline sign, are updated together. |
|
|
|
* Hardware wallets: several fixes in general; notable changes: |
|
|
|
- The BitBox02 is now supported (#5993) |
|
|
|
- Multisig support for Coldcard (#5440) |
|
|
|
- Compatibility with latest Trezor fw (#6064, #6198, #5692) |
|
|
|
* Dependencies (see README for install instructions): |
|
|
|
- libsecp256k1 is now required (previously optional). python-ecdsa |
|
|
|
remains a dependency but it is now only used for DNSSEC. |
|
|
|
- Added: either one of pycryptodomex or cryptography is now required, |
|
|
|
mainly due to LN (previously pycryptodomex was optional, for fast AES) |
|
|
|
- Removed: jsonrpclib-pelix, the JSON-RPC library used for CLI/daemon |
|
|
|
* Qt GUI: several changes, notably: |
|
|
|
- Separation between output selection and transaction finalization. |
|
|
|
- Coin selection moved to the Coins tab, and it affects all txns, |
|
|
|
e.g. RBF fee-bumping, LN channel opens, submarine swaps. |
|
|
|
- Editable tx preview dialog that allows e.g. changing the locktime, |
|
|
|
toggling RBF, and manual coinjoins. |
|
|
|
* Http PayServer changes: the electrum-merchant repository has been |
|
|
|
integrated directly into the main codebase. |
|
|
|
* Android: |
|
|
|
- We now build two APKs, one for ARMv7 and one for ARMv8 |
|
|
|
- The kivy GUI now supports importing BIP39 seeds |
|
|
|
- Each wallet on kivy now can have a separate generic password, |
|
|
|
using which the wallet files are encrypted. An optional PIN, |
|
|
|
shared among all wallets, can be added to get prompted for spends. |
|
|
|
* The API of several CLI/RPC commands have changed, and several new |
|
|
|
commands have been introduced (mainly for LN). |
|
|
|
* Distributables: |
|
|
|
- The .tar.gz source dist is now built reproducibly. |
|
|
|
Relatedly, we no longer distribute a .zip sdist. |
|
|
|
- The MacOS binary now conforms to macOS 10.15; it is notarized |
|
|
|
by Apple. This required bumping the min macOS version to 10.13. |
|
|
|
Startup times should now be faster on 10.15. (#6128, #6225) |
|
|
|
* Transactions: |
|
|
|
- we now grind low R for ECDSA signatures to match bitcoind (#5820) |
|
|
|
* Lots and lots of other minor bugfixes and improvements. |
|
|
|
|
|
|
|
* Lightning Network |
|
|
|
* Qt GUI: Separation between output selection and transaction finalization. |
|
|
|
* Http PayServer can be configured from GUI |
