| | 123 | * grub-script-check fails on scripts containing no commands. |
| | 124 | |
| | 125 | * Installation and other utility improvements: |

| | 129 | * Fix inconsistent use of `GRUB_CRYPTODISK_ENABLE' and |
| | 130 | `GRUB_ENABLE_CRYPTODISK'; the latter is now used consistently. |
| | 131 | * grub-mount handles symbolic links to directories. |

| | 140 | variable and `GRUB_TIMEOUT_STYLE' configuration key for grub-mkconfig. |
| | 141 | Menu hotkeys pressed during a hidden timeout now boot the corresponding |
| | 142 | menu entry immediately. |

| | 145 | * Set menu entry class to primary OS name returned by os-prober to display |
| | 146 | OS specific icon. |
| | 147 | * On Linux x86 detect EFI word size in grub-install and automatically select |
| | 148 | correct platform (x86_64-efi or i386-efi) to install. Requires Linux kernel |
| | 149 | 4.0 or higher. |
| | 150 | |
| | 151 | * Build system: |
| | 152 | * Remove all uses of nested functions; GRUB no longer requires an |
| | 153 | executable stack. |
| | 154 | * Fix documentation build with Texinfo >= 5.1. |
| | 155 | * More robust and documented cross-compiling support. |
| | 156 | * Partial clang support for some platforms (experimental). |
| | 157 | * Partial mingw64 x86_64-efi compile support (highly experimental). |
| | 158 | * Partial mingw32 i386-* (other than already present i386-pc) |
| | 159 | compile support (highly experimental). |
| | 160 | * Support for grub-mkpasswd on Windows. |
| | 161 | * Eliminate the use of AutoGen. This allowed some performance |
| | 162 | improvements to the build system. |
| | 163 | * Remove variable length arrays. |
| | 164 | * OpenBSD compile and tools support (NetBSD and FreeBSD were already supported). |
| | 165 | * Fix build with FreeType >= 2.5.1. |
| | 166 | * Make gentpl.py compatible with Python 3. It now requires at least |
| | 167 | Python 2.6. |
| | 168 | * modinfo.sh contains build information now. |
| | 169 | * Added many new tests to improve robustness. |
| | 170 | * Target is built without libgcc now. Necessary builtins are reimplemented |
| | 171 | directly. This removes requirement for target-specific runtime on build |
| | 172 | system. |
| | 173 | * emu libusb support removed (was broken and unmaintained). |
| | 174 | * powerpc64le compile support. |
| | 175 | * Use fixed timestamp when generating GRUB image for reproducible builds. |
| | 176 | * Verify at build time that modules contain only supported relocations and their |
| | 177 | structure matches what boot-time module loader expects. |
| | 178 | * Do not require fonts on powerpc-ieee1275. |
| | 179 | |
| | 180 | * Revision control moved to git. |
