Changes:

• Implement numpad arrows/home/end/pgup/pgdn/ins/del when num lock is off.
• Extra keys: handle multiple defined special buttons and in popup. Fix for https://github.com/termux/termux-app/issues/1881.
• ~/.termux/termux.properties: add option fullscreen to toggle fullscreen mode. You may need to enable use-fullscreen-workaround on some devices to fix layout issues, though on some devices it still doesn't work properly. Consider fullscreen mode as unstable for now.
• ~/.termux/termux.properties: add option default-working-directory which allows to open Termux in a specified directory instead of home.
• Added back PNG icons in addition to current adaptive/vector icon. This should fix issues with launchers still not supporting adaptive icons.
• Export current application version as environment variable TERMUX_VERSION.
• Update bootstrap archives.

From this point Termux does split-apk builds. One APK per CPU architecture: for aarch64, arm, i686 and x86_64.
