# Release 4.4.6 (August 18, 2023) (security update)
 * Lightning:
   - security fix: multiple lightning-related security issues have
     been fixed. We will disclose these in detail on 2023-09-11.
     These release notes will also be updated at that time.
     In the meantime, please update.
   - fix: cannot sweep from channel after local-force-close, if using
     imported channel backup (#8536). Fixing this required adding a
     new field (local_payment_pubkey) to the channel backup
     import/export format and bumping its version number
     (v0->v1). Both v0 and v1 can be imported, and we only export v1
     backups. When you force close a channel, the GUI will prompt you
     to save a backup. In that case, you must export the backup using
     the updated Electrum, and not rely on a backup made with an older
     release of Electrum.  Note that if you request a force close from
     the remote node or co-op close, you do not need to save a channel
     backup.
   - fix: we would sometimes attempt sending MPP even if not supported
     by the invoice (2cf6173c)
 * QML GUI:
   - fix lnurl-pay when config.BTC_AMOUNTS_ADD_THOUSANDS_SEP is True
     (5b4df759)

# Release 4.4.3 (May 11, 2023)
 * Intentionally break multisig wallets that have heterogeneous master
   keys. Versions 4.4.0 to 4.4.2 of Electrum for Android did not check
   that master keys used the same script type. This may have resulted
   in the creation of multisig wallets that cannot be spent from
   with any existing version of Electrum. It is not sure whether any
   users are affected by this; if there are any, we will publish
   instructions on how to spend those coins (#8417, #8418).

   - do not disconnect on "warning" messages (6fade55d)

# Release 4.4.0 (April 18, 2023)

 * New Android app, using QML instead of Kivy

   - This release still on python3.8
   - Feature parity with Kivy
   - Android Back button used throughout, for cancel/close/back
   - Note: two topbar menus; tap wallet name for wallet menu, tap
     network orb for application menu
   - Note: long-press Receive/Send for list of payment requests/invoices
 * Qt GUI improvements
   - New onchain transaction creation flow, with configurable preview
   - Various options have been moved to toolbars, where their effect
     can be more directly observed.
 * Privacy features:
    - lightning: support for option scid_alias.
    - Qt GUI: UTXO privacy analysis: this dialog displays all the
      wallet transactions that are either parent of a UTXO, or can be
      related to it through address reuse (Note that in the case of
      address reuse, it does not display children transactions.)
    - Coins tab: New menu that lets users easily spend a selection
      of UTXOs into a new channel, or into a submarine swap (Qt GUI).
 * Internal:
    - Lightning invoices are regenerated everytime routing hints are
      deprecated due to liquidity changes.
    - Script descriptors are used internally to sign transactions.


Reproducible: Always
