GRUB2 Editor received a new minor release today, mainly to update the openSUSE Build Service packages. The changelog is indeed tiny:
*ADDED: Install on the boot sector of a partition instead of the MBR.
*FIXED: Fix installation detection in Gentoo.
*FIXED: Fix translation loading.
Actually it’s a release straight from git, no planning had been made. The changes are minimum since v0.5.5.
Translations included in the release: ca cs da de el es et fr ga hu lt nb nl pl pt pt_BR ru sv uk zh_TW
