+Subject: Add recognition of more LaTeX commands for tex filetype detection
+
+Since filetype detection of TeX files defaults to plaintex, we've added
+detection of some additional LaTeX commands to help sway the detection
+to LaTeX.

+Subject: Document Debian's decision to disable modelines by default
+
+Modelines have historically been a source of vulnerabilities in Vim.
+As long as it remains a "blacklist suspected/proven dangerous options"
+instead of a "whitelist allowed options" piece of functionality,
+Debian's system-wide vimrc will maintain this setting.  As such, the
+documentation needs to be updated to reflect the induced behavior.

+This is used only in the vim-tiny package to allow a specific
+configuration for vim-tiny's vi.  The vim-tiny package is substantially
+different from other Vim packages, so it does not make sense to
+share the same config.

+Subject: patch 8.1.1366: using expressions in a modeline is unsafe
+
+Problem:    Using expressions in a modeline is unsafe.
+Solution:   Disallow using expressions in a modeline, unless the
+            'modelineexpr' option is set.  Update help, add more tests.
+
+(cherry picked from commit 110289e78195b6d01e1e6ad26ad450de476d41c1)

+Subject: Support defining compilation date in $SOURCE_DATE_EPOCH
+
+There is an ongoing effort[0] to make FOSS software reproducibly
+buildable.  In order to make Vim build reproducibly, it is necessary to
+allow defining the date/time that is part of VIM_VERSION_LONG as part of
+the build process.
+
+This commit enables that by adding support for the SOURCE_DATE_EPOCH
+spec[1].  When the $SOURCE_DATE_EPOCH environment variable is defined,
+it will be used to populate the BUILD_DATE preprocessor define.
+
+If BUILD_DATE is not defined, the existing behavior of relying on the
+preprocessor's __DATE__/__TIME__ symbols will be used.
