Electron Cash 3.3.6 available for Windows, Mac & Linux

3.3.6 Changes:

Support for op_return_raw= URI parameter to 'bitcoincash:' URIs. This paremeter is for raw hex to be used as the OP_RETURN payload (0x6a will always be prefixed to this raw hex.) (markblundeberg)
Testnet wallets were using the wrong bip32 key headers. They SHOULD accept & generate tpub/tprv on testnet but instead the keys generated were xpub/xprv. This was not to spec and has been fixed but, it may mean you will need to regenerate your testnet wallets form mnemonic seed. :/ (cculianu)
Added "Check for updates..." mechanism which is enabled by default (check is done once per hour). See Preferences -> General to disable auto check. Or Help -> "Check for updates..." for manual checking. (cculianu)
Added "Dark" theme to UI. See Preferences -> General (cculianu)
Fixed incompatibility bug where generated QR images were uppercase-only BITCOINCASH: which caused problems with some buggy wallet implementations. We switched back to generating 'bitcoincash:' (mixed-case) URIs, which is more compatible. (cculianu)
Added "Export contacts" facility to UI so you can export all your contacts to a file. (Strangely, we had "Import contacts", but no export!) (cculianu)
Added "Wallet -> Rebuild history" to Qt GUI. Allows users to re-synch entire wallet from server, on demand. (commit: a72b2a72, cculianu)
Request fee estimate from ElectrumX/ElectronX server every 20 minutes (cculianu)
Performance improvements for wallets with huge numbers of tx's (cculianu)
Trezor bugfix (SomberNight)
Append HMAC to Bitbox messages (TheCharlatan)
Android fixes (mhsmith)
Various internal bugfixes and code refactoring (cculianu, ecdsa, SomberNight)
servers.json updated (torusJKL)
Fixed a compatibility issue with Qt 5.12 (SomberNight, cculianu)
