 sodium_compat was updated to v1.12.1 in [46858] for WordPress 5.3.1.

 Two new releases have been made since then:
 https://github.com/paragonie/sodium_compat/releases/tag/v1.12.2
 https://github.com/paragonie/sodium_compat/releases/tag/v1.13.0

 List of changes from v1.12.1 to v1.13.0:
 https://github.com/paragonie/sodium_compat/compare/v1.12.1...v1.13.0

 For WordPress 5.6, one more particular fix is relevant for PHP 8
 compatibility:
 https://github.com/paragonie/sodium_compat/pull/119

 In PHP 8, the `MB_OVERLOAD_STRING` constant has been removed along with
 the `mbstring` function overload feature. This is now causing a test
 failure:
 {{{
 1) Tests_File::test_file_signature_functions_as_expected
 Error: Undefined constant "MB_OVERLOAD_STRING"

 /var/www/build/wp-admin/includes/file.php:1348
 /var/www/tests/phpunit/tests/file.php:198
 }}}

 The PR above is merged and fixes the issue. However, a new release is not
 tagged yet, so we'll have to backport that commit separately for now, and
 keep an eye on the next release.
