# Release 1.7
-* Synchronization waits until transactions have 2 confirmations before
-creating new addresses. This makes recovery from seed more robust, but
-it might create unwanted gaps if you use Electrum 1.7 together with
-older versions of Electrum.
+* The wallet does not create new addresses until transactions have 2
+confirmations. This makes recovery from seed more robust. Note that it

-* The Wall has been replaced by an interactive Python console. Wallet
-and Blockchain functions can be accessed through it. The goal is to
-let users extend Electrum through custom scripts.
+* An interactive Python console replaces the 'wall' tab. The provided
+python environment gives users access to the wallet and gui. Custom
+scripts an be loaded with a "run(filename)" command. Tab-completions
+are available.
-* The location of the Electrum folder in Windows changed from LOCALAPPDATA
-to APPDATA. Discussion on this topic can be found here: https://bitcointalk.org/index.php?topic=144575.0

+Here is how to sign a transaction with an offline Electrum wallet.
+
+1. With your online (seedless) wallet, create the transaction using mktx:
+
+./electrum mktx 1Cpf9zb5Rm5Z5qmmGezn6ERxFWvwuZ6UCx 0.1
+{
+ "complete": false,
+ "hex": "010000000296f054a6eccd3051444aec20e9c5c9b58739e70c7d958e4eb03587acf99d02e70000000000ffffffffdf350752fe6e27534633bb59327d9feb347756fe8d6e5b0b56312aca57df0eb30000000000ffffffff02f4345c35000000001976a914aaf437e25805f288141bfcdc27887ee5492bd13188ac80969800000000001976a91481acc8b7f9ec7cbf45a02dd8b758c6ac6a1481ca88ac00000000",
+ "input_info": "[{'scriptPubKey':'76a91411bbdc6e3a27c44644d83f783ca7df3bdc2778e688ac','electrumKeyID':(15,False),'vout':0,'txid':u'e7029df9ac8735b04e8e957d0ce73987b5c9c5e920ec4a445130cdeca654f096'},{'scriptPubKey':'76a914aaf437e25805f288141bfcdc27887ee5492bd13188ac','electrumKeyID':(112,True),'vout':0,'txid':u'b30edf57ca2a31560b5b6e8dfe567734eb9f7d3259bb334653276efe520735df'}]"
+}
+
+Note that returned json contains the unsigned tx in "hex". The field
+"complete" is false because the transaction is not signed, and
+"input_info" contains parameters that need to be passed to the offline
+wallet so that it knows which private keys to generate.
+
+2. Sign the transaction with your offline wallet: pass "hex" and "input_info" to 'signrawtransaction':
