+    `GRUB_ENABLE_CRYPTODISK'; the latter is now used consistently.
+  * grub-mount handles symbolic links to directories.
+  * Support disabling submenus with `GRUB_DISABLE_SUBMENU' configuration key
+    for grub-mkconfig.

+    executable stack.
+  * Fix documentation build with Texinfo >= 5.1.
+  * More robust and documented cross-compiling support.
+  * Partial clang support for some platforms (experimental).
+  * Partial mingw64 x86_64-efi compile support (highly experimental).
+  * Partial mingw32 i386-* (other than already present i386-pc)
+    compile support (highly experimental).
+  * Support for grub-mkpasswd on Windows.
+  * Eliminate the use of AutoGen.  This allowed some performance
+    improvements to the build system.
+  * Remove variable length arrays.
+  * OpenBSD compile and tools support (NetBSD and FreeBSD were already supported).
+  * Fix build with FreeType >= 2.5.1.
+  * Make gentpl.py compatible with Python 3.  It now requires at least
+    Python 2.6.
+  * modinfo.sh contains build information now.
+  * Added many new tests to improve robustness.
+  * Target is built without libgcc now. Necessary builtins are reimplemented
+    directly. This removes requirement for target-specific runtime on build
+    system.
+  * emu libusb support removed (was broken and unmaintained).
+  * powerpc64le compile support.
+  * Use fixed timestamp when generating GRUB image for reproducible builds.
+  * Verify at build time that modules contain only supported relocations and their
+    structure matches what boot-time module loader expects.
+  * Do not require fonts on powerpc-ieee1275.
+
+* Revision control moved to git.

+
+   --amend=FILE FILE maps from an SHA1 to perl code (i.e., s/old/new/) that
+                  makes a change to SHA1's commit log text or metadata.
+   --append-dot append a dot to the first line of each commit message if
+                  there is no other punctuation or blank at the end.
+   --no-cluster never cluster commit messages under the same date/author
+                  header; the default is to cluster adjacent commit messages
+                  if their headers are the same and neither commit message
+                  contains multiple paragraphs.
+   --srcdir=DIR the root of the source tree, from which the .git/
+                  directory can be derived.
+   --since=DATE convert only the logs since DATE;
+                  the default is to convert all log entries.
+   --format=FMT set format string for commit subject and body;
+                  see 'man git-log' for the list of format metacharacters;
+                  the default is '%s%n%b%n'
+   --strip-tab  remove one additional leading TAB from commit message lines.
+   --strip-cherry-pick  remove data inserted by "git cherry-pick";
+                  this includes the "cherry picked from commit ..." line,
+                  and the possible final "Conflicts:" paragraph.
+   --help       display this help and exit
+   --version    output version information and exit
+
+EXAMPLE:
+
+  $ME --since=2008-01-01 > ChangeLog
+  $ME -- -n 5 foo > last-5-commits-to-branch-foo
+
+SPECIAL SYNTAX:
+
+The following types of strings are interpreted specially when they appear
+at the beginning of a log message line.  They are not copied to the output.
+
+  Copyright-paperwork-exempt: Yes
+    Append the "(tiny change)" notation to the usual "date name email"
+    ChangeLog header to mark a change that does not require a copyright
+    assignment.
+  Co-authored-by: Joe User <user\@example.com>
+    List the specified name and email address on a second
+    ChangeLog header, denoting a co-author.
+  Signed-off-by: Joe User <user\@example.com>
+    These lines are simply elided.
+
+In a FILE specified via --amend, comment lines (starting with "#") are ignored.
+FILE must consist of <SHA,CODE+> pairs where SHA is a 40-byte SHA1 (alone on
+a line) referring to a commit in the current project, and CODE refers to one
+or more consecutive lines of Perl code.  Pairs must be separated by one or
+more blank line.
+
+Here is sample input for use with --amend=FILE, from coreutils:

+
+To register your own verifier call @samp{grub_verifier_register} with a
+structure pointing to your functions.
+
+The interface is inspired by hash interface with @samp{init}/@samp{write}/@samp{fini}.
+
+There are eesntially 2 ways of using it: hashing and whole-file verification:
+
+With hashing approach:
+During @samp{init} you decide whether you want to check given file and init context.
+In @samp{write} you update you hashing state.
+In @samp{fini} you check that hash matches the expected value/passes some check/...
+
+With whole-file verification:
+During @samp{init} you decide whether you want to check given file and init context.
+In @samp{write} you verify file and return error if it fails.
+You don't have @samp{fini}.
+
+Additional @samp{verify_string} receives various strings like kernel parameters to
+verify. Returning no error means successful verification and an error stops the current
+action.
+
+Detailed description of API:
+
+Every time a file is opened your @samp{init} function is called with file descriptor
+and file type. Your function can have following outcomes:
+
+@itemize
+
+@item returning no error and setting @samp{*flags} to @samp{GRUB_VERIFY_FLAGS_SKIP_VERIFICATION}.
+In this case your verifier will not be called anymore and your verifier is considered
+to have skipped verification
+
+@item returning error. Then opening of the fail will fail due to failed verification.
+
+@item returning no error and not setting @samp{*flags} to @samp{GRUB_VERIFY_FLAGS_SKIP_VERIFICATION}
+In this case verification is done as described in following section
+
+@end itemize
+
+In the third case your @samp{write} will be called with chunks of file. If you need the whole file in a single
+chunk then during @samp{init} set bit @samp{GRUB_VERIFY_FLAGS_SINGLE_CHUNK} in @samp{*flags}.
+During @samp{init} you may set @samp{*context} if you need additional context. At every iteration you may return
+an error and the the file will be considered as having failed the verification. If you return no error then
+verification continues.
+
+Optionally at the end of the file @samp{fini} if it exists is called with just the context. If you return
+no error during any of @samp{init}, @samp{write} and @samp{fini} then the file is considered as having
+succeded verification.
