Electron Cash 4.4.1 with CashFusion, CashTokens, and RPA

This is bugfix release of Electron Cash. The largest issue addresses is the bug with the Windows Portable version (#2833), which would delete the portable wallet directory, rather than preserve it alongside the binary (sorry!). Please upgrade at your earliest convenience if you are a Windows Portable user.

Electron Cash 4.3.1 with CashFusion and CashTokens

This is bugfix release of Electron Cash. It contains a highly recommended fix for a bad interactions between CashToken-containing UTXOs and CashFusion. Your tokens are safe, they cannot be burned -- however in some cases CashFusion would "see" CashToken-containing UTXOs and submit them for fusions. They would fail to be signed correctly, of course, so nothing could be lost, but it could lead to a potential situation of many failed fusions. This has been fixed! Additionally, a performance fix was added such that opening wallets is faster now than in 4.3.0. As such, it is highly recommended that all users of Electron Cash 4.3.0 upgrade as soon as possible to this release!

What's New in 4.3.1

• Added a performance fix for a situation which led to pessimization/slowdown when opening wallets in some cases (cculianu)
• Added a fix where CashFusion was "seeing" token-containing UTXOs. Not normally an issue but if they have significant funds on them, this could cause fusions to fail (cculianu).
• Fixed a typo: "Cateogry" -> "Category" ##2617 (7e378be)
• Fix for exoteric bug/problem on Python 3.11 in some rare cases.

Electron Cash 4.2.10 with CashFusion

This is a maintenance release of Electron Cash. It simply rights the "wrong" of temporary non-reproducibility in the Windows build. Additionally, an update to the internal compiler tools used to build the Windows version should improve performance and stability for Windows users. It is strongly recommended that Windows users update to this version at their earliest convenience. Also in this release: a fix-up for dark mode on Linux & Windows.

What's New in 4.2.10

• Windows build: Restored reproducibility of the Windows build #2444 (Axel Gembe)
• Removal of dead code (cculianu)

Electron Cash 4.2.9 with CashFusion

This is a bugfix release of Electron Cash. Importantly, Windows crash issues when using the LNS UI have been all (hopefully) addressed. In addition, some minor UI flow issues with the LNS UI were addressed. Also, perhaps most importantly, the web3 python package has been made optional. Users not interested in LNS Names need not install this package and the app will continue to run as before. This, in particular, is important for package maintainers for e.g. Fedora and other distros which do not offer the python-web3 package, so that they can continue to offer electron-cash as a distro-level package (even if the python-web3 package is missing from the distro).

What's New in 4.2.9

• LNS: Fix crash in multiple_result_picker (cculianu)
• LNS: Make the web3 dependencies optional #2441. This allows distro packages to not have to pull them in to provide electron-cash. (cculianu)
• LNS: Fix to the "add to contacts" button + misc code nits (cculianu)
• Qt: Disable destroyed_print_error unless a static flag is set. This fixes some of the crash issues seen on Windows. (cculianu)
• LNS: Bugfix whereby GUI was being sometimes access from a thread. This fixes the remaining portion (hopefully) of the crash issues seen on Windows. (cculianu)
• LNS: Misc fixups and code cleanup (cculianu)
