+## Regression tests
+
+You are **strongly encouraged** to add regression tests. Regression tests are great,

+
+* ensure that your contribution will never completely stop working.
+
+* makes code reviews easier, because it becomes very clear what the code is
+  supposed to do.
+
+For functional changes, you most likely want to add a test to
+[`tests/integration_tests.rs`](https://github.com/sharkdp/bat/blob/master/tests/integration_tests.rs).
+Look at existing tests to know how to write a new test. In short, you will
+invoke the `bat` binary with a certain set of arguments, and then assert on

 The [`prettybat`](https://github.com/eth-p/bat-extras/blob/master/doc/prettybat.md) script is a wrapper that will format code and print it with `bat`.
 
+#### Highlighting `--help` messages
+
+You can use `bat` to colorize help text: `$ cp --help | bat -plhelp`
+
+You can also use a wrapper around this:
+
+```bash
+# in your .bashrc/.zshrc/*rc
+alias bathelp='bat --plain --language=help'
+help() {
+    "$@" --help 2>&1 | bathelp
+}
+```
+
+Then you can do `$ help cp` or `$ help git commit`.
+
+When you are using `zsh`, you can also use global aliases to override `-h` and `--help` entirely:
+
+```bash
+alias -g -- -h='-h 2>&1 | bat --language=help --style=plain'
+alias -g -- --help='--help 2>&1 | bat --language=help --style=plain'
+```
+
+This way, you can keep on using `cp --help`, but get colorized help pages.
+
+Be aware that in some cases, `-h` may not be a shorthand of `--help` (for example with `ls`).
+
+Please report any issues with the help syntax in [this repository](https://github.com/victor-gp/cmd-help-sublime-syntax).

+
+						*{subject}* *E149* *E661*
+:h[elp] {subject}	Like ":help", additionally jump to the tag {subject}.
+			For example:  >
+				:help options
+
+<			{subject} can include wildcards such as "*", "?" and
+#   ^ punctuation.definition.constant.begin
+#    ^^^^^^^ constant.numeric
+#           ^ punctuation.definition.constant.end
+			"[a-z]":
+			   :help z?	jump to help for any "z" command
+			   :help z.	jump to the help for "z."
+			But when a tag exists it is taken literally:
+			   :help :?	jump to help for ":?"
+
+			If there is no full match for the pattern, or there
+			are several matches, the "best" match will be used.
+			A sophisticated algorithm is used to decide which
+			match is better than another one.  These items are
+			considered in the computation:
+			- A match with same case is much better than a match
+			  with different case.
+			- A match that starts after a non-alphanumeric
+			  character is better than a match in the middle of a
+			  word.
+			- A match at or near the beginning of the tag is
+			  better than a match further on.
+			- The more alphanumeric characters match, the better.
+			- The shorter the length of the match, the better.
+
+			The 'helplang' option is used to select a language, if
+			the {subject} is available in several languages.
+			To find a tag in a specific language, append "@ab",
+			where "ab" is the two-letter language code.  See
+			|help-translated|.
+
+			Note that the longer the {subject} you give, the less
+			matches will be found.  You can get an idea how this
+			all works by using commandline completion (type CTRL-D
+#                                                  ^^^^^^ markup.underline.link.key
+			after ":help subject" |c_CTRL-D|).
+			If there are several matches, you can have them listed
+			by hitting CTRL-D.  Example: >
+				:help cont<Ctrl-D>
+
+<			Instead of typing ":help CTRL-V" to search for help
+			for CTRL-V you can type: >
+				:help ^V
+<			This also works together with other characters, for
+			example to find help for CTRL-V in Insert mode: >
+				:help i^V
+<
+			It is also possible to first do ":help" and then
+			use ":tag {pattern}" in the help window.  The
+			":tnext" command can then be used to jump to other
+			matches, "tselect" to list matches and choose one. >
+				:help index
+				:tselect /.*mode
+
+<			When there is no argument you will see matches for
+			"help", to avoid listing all possible matches (that
+			would be very slow).
+			The number of matches displayed is limited to 300.
+
+			The `:help` command can be followed by '|' and another
+			command, but you don't need to escape the '|' inside a
+			help command.  So these both work: >
+				:help |
+				:help k| only
+<			Note that a space before the '|' is seen as part of
+#   ^^^^ constant.other.note
+			the ":help" argument.
+			You can also use <NL> or <CR> to separate the help
+			command from a following command.  You need to type
+			CTRL-V first to insert the <NL> or <CR>.  Example: >
+				:help so<C-V><CR>only
+<
+
+:h[elp]! [subject]	Like ":help", but in non-English help files prefer to
+			find a tag in a file with the same language as the
+			current file.  See |help-translated|.
+
+							*:helpc* *:helpclose*
+:helpc[lose]		Close one help window, if there is one.
+			Vim will try to restore the window layout (including
+			cursor position) to the same layout it was before
+			opening the help window initially.  This might cause
+			triggering several autocommands.
+
+							*:helpg* *:helpgrep*
+:helpg[rep] {pattern}[@xx]
+			Search all help text files and make a list of lines
+			in which {pattern} matches.  Jumps to the first match.
+			The optional [@xx] specifies that only matches in the
+			"xx" language are to be found.
+			You can navigate through the matches with the
+			|quickfix| commands, e.g., |:cnext| to jump to the
+			next one.  Or use |:cwindow| to get the list of
+			matches in the quickfix window.
+			{pattern} is used as a Vim regexp |pattern|.
+			'ignorecase' is not used, add "\c" to ignore case.
+			Example for case sensitive search: >
+				:helpgrep Uganda
+<			Example for case ignoring search: >
+				:helpgrep uganda\c
+<			Example for searching in French help: >
+				:helpgrep backspace@fr
+<			The pattern does not support line breaks, it must
+			match within one line.  You can use |:grep| instead,
+			but then you need to get the list of help files in a
+			complicated way.
+			Cannot be followed by another command, everything is
+			used as part of the pattern.  But you can use
+			|:execute| when needed.
+			Compressed help files will not be searched (Fedora
+			compresses the help files).
+
+							*:lh* *:lhelpgrep*
+:lh[elpgrep] {pattern}[@xx]
+			Same as ":helpgrep", except the location list is used
+			instead of the quickfix list.  If the help window is
+			already opened, then the location list for that window
+			is used.  Otherwise, a new help window is opened and
+			the location list for that window is set.  The
+			location list for the current window is not changed
+			then.
+
+							*:exu* *:exusage*
+:exu[sage]		Show help on Ex commands.  Added to simulate the Nvi
+			command.
+
+							*:viu* *:viusage*
+:viu[sage]		Show help on Normal mode commands.  Added to simulate
+			the Nvi command.
+
+When no argument is given to |:help| the file given with the 'helpfile' option
+will be opened.  Otherwise the specified tag is searched for in all "doc/tags"
+files in the directories specified in the 'runtimepath' option.
+
+If you would like to open the help in the current window, see this tip:
+|help-curwin|.
+
+The initial height of the help window can be set with the 'helpheight' option
+(default 20).
+						*help-buffer-options*
+When the help buffer is created, several local options are set to make sure
+the help text is displayed as it was intended:
+    'iskeyword'		nearly all ASCII chars except ' ', '*', '"' and '|'
+    'foldmethod'	"manual"
+    'tabstop'		8
+    'arabic'		off
+    'binary'		off
+    'buflisted'		off
+    'cursorbind'	off
+    'diff'		off
+    'foldenable'	off
+    'list'		off
+    'modifiable'	off
+    'number'		off
+    'relativenumber'	off
+    'rightleft'		off
+    'scrollbind'	off
+    'spell'		off
+
+Jump to specific subjects by using tags.  This can be done in two ways:
+- Use the "CTRL-]" command while standing on the name of a command or option.
+  This only works when the tag is a keyword.  "<C-Leftmouse>" and
+  "g<LeftMouse>" work just like "CTRL-]".
+- use the ":ta {subject}" command.  This also works with non-keyword
+  characters.
+
+Use CTRL-T or CTRL-O to jump back.
+Use ":q" to close the help window.
+
+If there are several matches for an item you are looking for, this is how you
+can jump to each one of them:
+1. Open a help window
+2. Use the ":tag" command with a slash prepended to the tag.  E.g.: >
+	:tag /min
+3. Use ":tnext" to jump to the next matching tag.
+
+It is possible to add help files for plugins and other items.  You don't need
+to change the distributed help files for that.  See |add-local-help|.
+
+To write a local help file, see |write-local-help|.
+
+Note that the title lines from the local help files are automagically added to
+the "LOCAL ADDITIONS" section in the "help.txt" help file |local-additions|.
+This is done when viewing the file in Vim, the file itself is not changed.  It
+is done by going through all help files and obtaining the first line of each
+file.  The files in $VIMRUNTIME/doc are skipped.
+
+							*help-xterm-window*
+If you want to have the help in another xterm window, you could use this
+command: >
+	:!xterm -e vim +help &
+<
+
+					*:helpt* *:helptags*
+			*E150* *E151* *E152* *E153* *E154* *E670* *E856*
+:helpt[ags] [++t] {dir}
+			Generate the help tags file(s) for directory {dir}.
+			When {dir} is ALL then all "doc" directories in
+			'runtimepath' will be used.
+
+			All "*.txt" and "*.??x" files in the directory and
+			sub-directories are scanned for a help tag definition
+			in between stars.  The "*.??x" files are for
+			translated docs, they generate the "tags-??" file, see
+			|help-translated|.  The generated tags files are
+			sorted.
+			When there are duplicates an error message is given.
+			An existing tags file is silently overwritten.
+
+			The optional "++t" argument forces adding the
+			"help-tags" tag.  This is also done when the {dir} is
+			equal to $VIMRUNTIME/doc.
+
+			To rebuild the help tags in the runtime directory
+			(requires write permission there): >
+				:helptags $VIMRUNTIME/doc
+<
+
+
+==============================================================================
+2. Translated help files				*help-translated*
+
+It is possible to add translated help files, next to the original English help
+files.  Vim will search for all help in "doc" directories in 'runtimepath'.
+
+At this moment translations are available for:
+	Chinese  - multiple authors
+	French   - translated by David Blanchet
+	Italian  - translated by Antonio Colombo
+	Japanese - multiple authors
+	Polish   - translated by Mikolaj Machowski
+	Russian  - translated by Vassily Ragosin
+See the Vim website to find them: http://www.vim.org/translations.php
+
+A set of translated help files consists of these files:
+
+	help.abx
+	howto.abx
+	...
+	tags-ab
+
+"ab" is the two-letter language code.  Thus for Italian the names are:
+
+	help.itx
+	howto.itx
+	...
+	tags-it
+
+The 'helplang' option can be set to the preferred language(s).  The default is
+set according to the environment.  Vim will first try to find a matching tag
+in the preferred language(s).  English is used when it cannot be found.
+
+To find a tag in a specific language, append "@ab" to a tag, where "ab" is the
+two-letter language code.  Example: >
+	:he user-manual@it
+	:he user-manual@en
+The first one finds the Italian user manual, even when 'helplang' is empty.
+The second one finds the English user manual, even when 'helplang' is set to
+"it".
+
+When using command-line completion for the ":help" command, the "@en"
+extension is only shown when a tag exists for multiple languages.  When the
+tag only exists for English "@en" is omitted.  When the first candidate has an
+"@ab" extension and it matches the first language in 'helplang' "@ab" is also
+omitted.
+
+When using |CTRL-]| or ":help!" in a non-English help file Vim will try to
+find the tag in the same language.  If not found then 'helplang' will be used
+to select a language.
+
+Help files must use latin1 or utf-8 encoding.  Vim assumes the encoding is
+utf-8 when finding non-ASCII characters in the first line.  Thus you must
+translate the header with "For Vim version".
+
+The same encoding must be used for the help files of one language in one
+directory.  You can use a different encoding for different languages and use
+a different encoding for help files of the same language but in a different
+directory.
+
+Hints for translators:
+- Do not translate the tags.  This makes it possible to use 'helplang' to
+  specify the preferred language.  You may add new tags in your language.
+- When you do not translate a part of a file, add tags to the English version,
+  using the "tag@en" notation.
+- Make a package with all the files and the tags file available for download.
+  Users can drop it in one of the "doc" directories and start use it.
+  Report this to Bram, so that he can add a link on www.vim.org.
+- Use the |:helptags| command to generate the tags files.  It will find all
+  languages in the specified directory.
+
+==============================================================================
+3. Writing help files					*help-writing*
+
+For ease of use, a Vim help file for a plugin should follow the format of the
+standard Vim help files, except for the first line.  If you are writing a new
+help file it's best to copy one of the existing files and use it as a
+template.
+
+The first line in a help file should have the following format:
+
+*plugin_name.txt*	{short description of the plugin}
+
+The first field is a help tag where ":help plugin_name" will jump to.  The
+remainder of the line, after a Tab, describes the plugin purpose in a short
+way.  This will show up in the "LOCAL ADDITIONS" section of the main help
+file.  Check there that it shows up properly: |local-additions|.
+
+If you want to add a version number or last modification date, put it in the
+second line, right aligned.
+
+At the bottom of the help file, place a Vim modeline to set the 'textwidth'
+and 'tabstop' options and the 'filetype' to "help".  Never set a global option
+in such a modeline, that can have undesired consequences.
+
+
+TAGS
+
+To define a help tag, place the name between asterisks (*tag-name*).  The
+tag-name should be different from all the Vim help tag names and ideally
+should begin with the name of the Vim plugin.  The tag name is usually right
+aligned on a line.
+
+When referring to an existing help tag and to create a hot-link, place the
+name between two bars (|) eg. |help-writing|.
+
+When referring to a Vim command and to create a hot-link, place the
+name between two backticks, eg. inside `:filetype`.  You will see this is
+highlighted as a command, like a code block (see below).
+
+When referring to a Vim option in the help file, place the option name between
+two single quotes, eg. 'statusline'
+
+When referring to any other technical term, such as a filename or function
+parameter, surround it in backticks, eg. `~/.path/to/init.vim`.
+
+
+HIGHLIGHTING
+
+To define a column heading, use a tilde character at the end of the line.
+This will highlight the column heading in a different color.  E.g.
+
+Column heading~
+#^^^^^^^^^^^^^ markup.heading.header
+#             ^ punctuation.definition.keyword
+
+To separate sections in a help file, place a series of '=' characters in a
+line starting from the first column.  The section separator line is highlighted
+differently.
+
+To quote a block of ex-commands verbatim, place a greater than (>) character
+at the end of the line before the block and a less than (<) character as the
+first non-blank on a line following the block.  Any line starting in column 1
+also implicitly stops the block of ex-commands before it.  E.g. >
+    function Example_Func()
+	echo "Example"
+    endfunction
+<
+
+The following are highlighted differently in a Vim help file:
+  - a special key name expressed either in <> notation as in <PageDown>, or
+    as a Ctrl character as in CTRL-X
+  - anything between {braces}, e.g. {lhs} and {rhs}
+
+The word "Note", "Notes" and similar automagically receive distinctive
+highlighting.  So do these:
+	*Todo	something to do
+	*Error	something wrong
+
+You can find the details in $VIMRUNTIME/syntax/help.vim

+
+Usage: bat [OPTIONS] [FILE]...
+       bat <COMMAND>
+
+Arguments:
+  [FILE]...
+          File(s) to print / concatenate. Use a dash ('-') or no argument at all to read from
+          standard input.
+
+Options:
+  -A, --show-all
+          Show non-printable characters like space, tab or newline. This option can also be used to
+          print binary files. Use '--tabs' to control the width of the tab-placeholders.
+
+      --nonprintable-notation <notation>
+          Set notation for non-printable characters.
+          
+          Possible values:
+            * unicode (␇, ␊, ␀, ..)
+            * caret   (^G, ^J, ^@, ..)
+
+      --binary <behavior>
+          How to treat binary content. (default: no-printing)
+          
+          Possible values:
+            * no-printing: do not print any binary content
+            * as-text: treat binary content as normal text
+
+  -p, --plain...
+          Only show plain style, no decorations. This is an alias for '--style=plain'. When '-p' is
+          used twice ('-pp'), it also disables automatic paging (alias for '--style=plain
+          --paging=never').
+
+  -l, --language <language>
+          Explicitly set the language for syntax highlighting. The language can be specified as a
+          name (like 'C++' or 'LaTeX') or possible file extension (like 'cpp', 'hpp' or 'md'). Use
+          '--list-languages' to show all supported language names and file extensions.
+
+  -H, --highlight-line <N:M>
+          Highlight the specified line ranges with a different background color For example:
+            '--highlight-line 40' highlights line 40
+            '--highlight-line 30:40' highlights lines 30 to 40
+            '--highlight-line :40' highlights lines 1 to 40
+            '--highlight-line 40:' highlights lines 40 to the end of the file
+            '--highlight-line 30:+10' highlights lines 30 to 40
+
+      --file-name <name>
+          Specify the name to display for a file. Useful when piping data to bat from STDIN when bat
+          does not otherwise know the filename. Note that the provided file name is also used for
+          syntax detection.
+
+  -d, --diff
+          Only show lines that have been added/removed/modified with respect to the Git index. Use
+          --diff-context=N to control how much context you want to see.
+
+      --diff-context <N>
+          Include N lines of context around added/removed/modified lines when using '--diff'.
+
+      --tabs <T>
+          Set the tab width to T spaces. Use a width of 0 to pass tabs through directly
+
+      --wrap <mode>
+          Specify the text-wrapping mode (*auto*, never, character). The '--terminal-width' option
+          can be used in addition to control the output width.
+
+  -S, --chop-long-lines
+          Truncate all lines longer than screen width. Alias for '--wrap=never'.
+
+      --terminal-width <width>
+          Explicitly set the width of the terminal instead of determining it automatically. If
+          prefixed with '+' or '-', the value will be treated as an offset to the actual terminal
+          width. See also: '--wrap'.
+
+  -n, --number
+          Only show line numbers, no other decorations. This is an alias for '--style=numbers'
+
+      --color <when>
+          Specify when to use colored output. The automatic mode only enables colors if an
+          interactive terminal is detected - colors are automatically disabled if the output goes to
+          a pipe.
+          Possible values: *auto*, never, always.
+
+      --italic-text <when>
+          Specify when to use ANSI sequences for italic text in the output. Possible values: always,
+          *never*.
+
+      --decorations <when>
+          Specify when to use the decorations that have been specified via '--style'. The automatic
+          mode only enables decorations if an interactive terminal is detected. Possible values:
+          *auto*, never, always.
+
+  -f, --force-colorization
+          Alias for '--decorations=always --color=always'. This is useful if the output of bat is
+          piped to another program, but you want to keep the colorization/decorations.
+
+      --paging <when>
+          Specify when to use the pager. To disable the pager, use --paging=never' or its
+          alias,'-P'. To disable the pager permanently, set BAT_PAGING to 'never'. To control which
+          pager is used, see the '--pager' option. Possible values: *auto*, never, always.
+
+      --pager <command>
+          Determine which pager is used. This option will override the PAGER and BAT_PAGER
+          environment variables. The default pager is 'less'. To control when the pager is used, see
+          the '--paging' option. Example: '--pager "less -RF"'.
+
+  -m, --map-syntax <glob:syntax>
+          Map a glob pattern to an existing syntax name. The glob pattern is matched on the full
+          path and the filename. For example, to highlight *.build files with the Python syntax, use
+          -m '*.build:Python'. To highlight files named '.myignore' with the Git Ignore syntax, use
+          -m '.myignore:Git Ignore'. Note that the right-hand side is the *name* of the syntax, not
+          a file extension.
+
+      --ignored-suffix <ignored-suffix>
+          Ignore extension. For example:
+            'bat --ignored-suffix ".dev" my_file.json.dev' will use JSON syntax, and ignore '.dev'
+
+      --theme <theme>
+          Set the theme for syntax highlighting. Use '--list-themes' to see all available themes. To
+          set a default theme, add the '--theme="..."' option to the configuration file or export
+          the BAT_THEME environment variable (e.g.: export BAT_THEME="...").
+          
+          Special values:
+          
+            * auto: Picks a dark or light theme depending on the terminal's colors (default).
+                    Use '--theme-light' and '--theme-dark' to customize the selected theme.
+              * auto:always: Detect the terminal's colors even when the output is redirected.
+              * auto:system: Detect the color scheme from the system-wide preference (macOS only).
+            * dark: Use the dark theme specified by '--theme-dark'.
+            * light: Use the light theme specified by '--theme-light'.
+
+      --theme-light <theme>
+          Sets the theme name for syntax highlighting used when the terminal uses a light
+          background. Use '--list-themes' to see all available themes. To set a default theme, add
+          the '--theme-light="..." option to the configuration file or export the BAT_THEME_LIGHT
+          environment variable (e.g. export BAT_THEME_LIGHT="...").
+
+      --theme-dark <theme>
+          Sets the theme name for syntax highlighting used when the terminal uses a dark background.
+          Use '--list-themes' to see all available themes. To set a default theme, add the
+          '--theme-dark="..." option to the configuration file or export the BAT_THEME_DARK
+          environment variable (e.g. export BAT_THEME_DARK="...").
+
+      --list-themes
+          Display a list of supported themes for syntax highlighting.
+
+  -s, --squeeze-blank
+          Squeeze consecutive empty lines into a single empty line.
+
+      --squeeze-limit <squeeze-limit>
+          Set the maximum number of consecutive empty lines to be printed.
+
+      --strip-ansi <when>
+          Specify when to strip ANSI escape sequences from the input. The automatic mode will remove
+          escape sequences unless the syntax highlighting language is plain text. Possible values:
+          auto, always, *never*.
+
+      --style <components>
+          Configure which elements (line numbers, file headers, grid borders, Git modifications, ..)
+          to display in addition to the file contents. The argument is a comma-separated list of
+          components to display (e.g. 'numbers,changes,grid') or a pre-defined style ('full'). To
+          set a default style, add the '--style=".."' option to the configuration file or export the
+          BAT_STYLE environment variable (e.g.: export BAT_STYLE="..").
+          
+          When styles are specified in multiple places, the "nearest" set of styles take precedence.
+          The command-line arguments are the highest priority, followed by the BAT_STYLE environment
+          variable, and then the configuration file. If any set of styles consists entirely of
+          components prefixed with "+" or "-", it will modify the previous set of styles instead of
+          replacing them.
+          
+          By default, the following components are enabled:
+            changes, grid, header-filename, numbers, snip
+          
+          Possible values:
+          
+            * default: enables recommended style components (default).
+            * full: enables all available components.
+            * auto: same as 'default', unless the output is piped.
+            * plain: disables all available components.
+            * changes: show Git modification markers.
+            * header: alias for 'header-filename'.
+            * header-filename: show filenames before the content.
+            * header-filesize: show file sizes before the content.
+            * grid: vertical/horizontal lines to separate side bar
+                    and the header from the content.
+            * rule: horizontal lines to delimit files.
+            * numbers: show line numbers in the side bar.
+            * snip: draw separation lines between distinct line ranges.
+
+  -r, --line-range <N:M>
+          Only print the specified range of lines for each file. For example:
+            '--line-range 30:40' prints lines 30 to 40
+            '--line-range :40' prints lines 1 to 40
+            '--line-range 40:' prints lines 40 to the end of the file
+            '--line-range 40' only prints line 40
+            '--line-range 30:+10' prints lines 30 to 40
+
+  -L, --list-languages
+          Display a list of supported languages for syntax highlighting.
+
+  -u, --unbuffered
+          This option exists for POSIX-compliance reasons ('u' is for 'unbuffered'). The output is
+          always unbuffered - this option is simply ignored.
+
+      --completion <SHELL>
+          Show shell completion for a certain shell. [possible values: bash, fish, zsh, ps1]
+
+      --diagnostic
+          Show diagnostic information for bug reports.
+
+      --acknowledgements
+          Show acknowledgements.
+
+      --set-terminal-title
+          Sets terminal title to filenames when using a pager.
+
+  -h, --help
+          Print help (see a summary with '-h')

 # Release checklist
 
-## Dependencies
-
-See this page for a good overview: https://deps.rs/repo/github/sharkdp/bat
-
-- [ ] Optional: update dependencies with `cargo update`. This is also done by
-      dependabot, so it is not strictly necessary.
-- [ ] Install [cargo-outdated](https://crates.io/crates/cargo-outdated). Check
-      for outdated dependencies with `cargo outdated --root-deps-only` and
-      decide for each of them whether we want to (manually) upgrade. This will
-      require changes to `Cargo.toml`.
-
 ## Version bump
 
 - [ ] Update version in `Cargo.toml`. Run `cargo build` to update `Cargo.lock`.
       Make sure to `git add` the `Cargo.lock` changes as well.
 - [ ] Find the current min. supported Rust version by running
-      `grep '^\s*MIN_SUPPORTED_RUST_VERSION' .github/workflows/CICD.yml`.
+      `cargo metadata --no-deps --format-version 1 | jq -r '.packages[0].rust_version'`.
 - [ ] Update the version and the min. supported Rust version in `README.md` and
-      `doc/README-*.md`. Check with `git grep -i 'rust.*1\.'` and
-      `git grep -i '1\..*rust'`.
-- [ ] Update `CHANGELOG.md`. Introduce a section for the new release.
+      `doc/README-*.md`. Check with
+      `git grep -i -e 'rust.*1\.' -e '1\..*rust' | grep README | grep -v tests/`.

       sure that it is available on the `PATH` (`bat --version` should show the
       new version).
 - [ ] Run `assets/create.sh` and check in the binary asset files.
 
 ## Documentation
 
-- [ ] Review the `-h` and `--help` texts
-- [ ] Review the `man` page
+- [ ] Review [`-h`](./short-help.txt), [`--help`](./long-help.txt), and the `man` page. The `man` page is shown in
+      the output of the CI job called *Documentation*, so look there.
