Release: Electrum 2.9 - Independence

Make sure to update your Electrum to be prepared for the coming Forks of Bitcoin United (BTCX) and Bitcoin Cash (BCC)!

Release Notes:

Release 2.9 - Independence (July 27th, 2017)

Multiple Chain Validation: Electrum will download and validate
block headers sent by servers that may follow different branches
of a fork in the Bitcoin blockchain. Instead of a linear sequence,
block headers are organized in a tree structure. Branching points
are located efficiently using binary search. The purpose of MCV is
to detect and handle blockchain forks that are invisible to the
classical SPV model.
The desired branch of a blockchain fork can be selected using the
network dialog. Branches are identified by the hash and height of
the diverging block. Coin splitting is possible using RBF
transaction (a tutorial will be added).
Multibit support: If the user enters a BIP39 seed (or uses a
hardware wallet), the full derivation path is configurable in the
install wizard.

Qt GUI:
