This page lists versions of Electrum that are incompatible with the
|
|
previous version. These incompatibilities are caused by a change in
|
|
the key derivation algorithm.
|
|
|
|
Wallets created before the change are incompatible with the new
|
|
version, and that users need to move their bitcoins. We apologize for
|
|
the inconvenience. We try to keep this kind of upgrades as rare as
|
|
possible.

LIST OF UPGRADES:
|
|
-----------------
|
|
|
|
Version 0.34: The key derivation was changed again in version 0.34, in order to offer "type 2 wallet" capabilities.
|
|
Version 0.31: This version fixes a vulnerability in the key generation function.

HOW TO UPGRADE:
|
|
---------------
|
|
|
|
If your wallet is deprecated, you will see a message asking you to
|
|
create a new wallet and to move your balance to the new wallet.
|
|
|
|
Here are the steps that you need to follow:
|
|
* create a new wallet with the new version of Electrum: /path/to/new/electrum.py -w my_new_wallet.dat
|
|
* copy a receiving address from the new wallet
|
|
* open your old wallet with the old version of Electrum: /path/to/old/electrum.py -w my_old_wallet
|
|
* move your entire balance to the new address.
|
|
|
|
Note that you may keep your current seed. For this, all you need to do
|
|
is to create the new wallet using the wallet recovery procedure. You
|
|
will not recover your old wallet with the new software, but you will
|
|
get a new wallet instead.
