# Release 4.2.1 - (March 26, 2022)
 * Binaries:
   - Windows: we are dropping support for Windows 7. (#7728)
     Version 4.2.0 already unintentionally broke compatibility with
     Win7 and there is no easy way to restore and maintain support.
     Existing users can keep using version 4.1.5 for now, but should
     consider upgrading or changing their OS.
     Win8.1 still works but only Win10 is regularly tested.
   - bump bundled Python version (win, mac, appimage) to 3.9.11,
     (android) to 3.8.13 (1bb7ef92, #7721)
     (note these include a fix to an openssl DOS-vector CVE-2022-0778)
   - windows: bump pyinstaller to 4.10 and wine to 7.0 (#7721)
 * Kivy GUI:
   - fix "Child Pays For Parent" not working on Android (#7723)
   - revert to defaulting the UI language to English (25fee6a6)
 * Qt GUI:
   - macOS: fix opening "Preferences" segfaulting for some (#7725)
   - more resilient startup: better error-handling and fallback (#7447)
 * Library:
   - fix LN error/warning message-handling, and fix regression that
     errors during channel-open were not properly shown in GUI (a92dede4)
   - during LN chan open, do not backup wallet automatically (#7733)
   - Imported wallets: fix delete_address rm-ing too many txs (#7587)
   - fix potential deadlock in wallet.py (d3476b6b)
 * Hardware wallets:
   - ledger: add progress indicator to sign_transaction (#7516)
 * fix the "--portable" flag for AppImage, and for pip installs (#7732)

For those Windows7 users who want to try to upgrade to 4.2.0~4.2.1, try running Electrum directly from source.
The minimum python version is python v3.8 that's still supported by Windows7, only the bundled python dll to the Windows binaries (exe files) are python v3.9

Follow this guide to be able to run Electrum from source on Windows: /index.php?topic=5224252.msg53806954
But it needs an additional step because that was for old version of Electrum: now, it requires to build "libsecp256k1-0.dll" using "make_libsecp256k1.sh" in 'contrib' folder, however the script wont work on Windows.
There's a pre-compiled 64-bit 'libsecp256k1-0.dll' file provided by SomberNight here: github.com/spesmilo/electrum/issues/5976, but please read his reply first.
Extract it, then paste the file 'libsecp256k1-0.dll' in 'electrum' folder inside 'electrum-master'.

Disclaimer: I don't have a Win7 PC but I've tried running Electrum v4.2.1 with python 3.8 and it still works so it might work on Windows7.
