Version 2.4.2 was released today, with OSX and Windows binaries.
See
https://electrum.org/#downloadHowever, hardware wallets (trezor, ledger) are not supported in the current Windows binaries.
If you use a hardware wallet, please wait until we have better binaries.
Thanks for this wonderful wallet.
Is there a portable version for 2.4.*?
Not yet released. Guess it will be out soon. As mentioned above, Electrum-LTC released version 2.4.2.1 in all configurations (installer, stand alone etc..) so assume Electrum-BTC will be short on its heals. Most probably some issues to be resolved as 2.4 (BTC) also have no Trezor support at the moment.Correction, go to the link provided, see there is a standalone version for version 2.4.3 available
From the release notes:
# Release 2.4.3
