+\subsection{Full bleed printing}
+
+When preparing a book for press printing, you may be asked by the professional printer to output the document on a larger sheet than your target paper, and to reserve a trim area around it.
+This trick is often called “full bleed printing”.
+Your document will be printed on an oversized sheet that will then be mechanically cut down to the target size.
+You can specify the expected “trim” (or “bleed”) dimension, to be distributed evenly on all sides
+of the document:
+
+\code{papersize=\em{<paper size>}, bleed=\em{<measurement>}}.
+
+For instance, a US trade book with an extra 0.125 inch bleed area can be specified by \code{papersize=6in x 9in, bleed=0.25in}.
+The output paper size is then 6.25 per 9.25 inches, with the actual 6 per 9 inches inner content centered.
+
+Some packages, such as \autodoc:package{background} and \autodoc:package{cropmarks}, ensure their content extends over the trim area and thus indeed “bleeds” off the sides of the page, so that artifacts such as blank lines are avoided when the sheets are cut, would they be trimmed slightly differently for some assembling or technical reasons.
+
+Finally, there is also the case when the actual paper sheets available to you are larger than your target paper size, and yet you would want the output document to show properly centered:
+
+\code{papersize=\em{<paper size>}, sheetsize=\em{<actual paper size>}}.
+
+For instance, \code{papersize=6in x 9in, sheetsize=a4} produces an A4-dimensioned document, but with you content formatted as a 6 per 9 inches US trade book. You may, obviously, combine these options and also specify a bleed area.

+\em{Note on Unicode soft hyphens} — By default, soft hyphens (U+00AD) are interpreted as discretionary breaks, allowing line-breaking at that point (using the current font’s hyphen character).
+
+However, issues may arise when soft hyphens are used in ligatures, causing breaks between constituent characters and disrupting the ligature’s integrity.
+Rather than relying on soft hyphens, for instances requiring hyphenation in unknown words, consider adding an exception to the hyphenation rules instead, with \autodoc:command{\hyphenator:add-exceptions{<text>}} (where the text is a lowercase representation of the word, with dashes where hyphenation is allowed).
+
+Moreover, typists sometimes manually insert soft hyphens to rectify line-breaking issues in other typesetting systems.
+In SILE, leveraging language-specific hyphenation rules tends to be more reliable.
+Setting \autodoc:setting{typesetter.softHyphen} to \code{false} ignores soft hyphens entirely in the text, alleviating potential issues arising from their manual insertion.
+
+Soft hyphens can be inadvertently inserted by text editors or software, remaining invisible in the source text and causing unexpected output.
+Setting \autodoc:setting{typesetter.softHyphenWarning} to \code{true} triggers warnings upon encountering soft hyphens, aiding users in identifying and rectifying such instances, regardless of the previous setting.

 \use[module=packages.background]
-The \autodoc:package{background} package allows you to set the color of the canvas background (by drawing a solid color block the full size of the page on page initialization).
-The package provides a \autodoc:command{\background} command which requires at least one parameter, \autodoc:parameter{color=<color specification>}, and sets the background of the current and all following pages to that color.
-If you want to set only the current page background different from the default, use the parameter \autodoc:parameter{allpages=false}.
-The color specification in the same as specified in the \autodoc:package{color} package.
+As its name implies, the \autodoc:package{background} package allows you to set the color of the page canvas background or to use a background image extending to the full page width and height.
+
+The package provides a \autodoc:command{\background} command which requires one of the following parameters:
+\begin{itemize}
+\item{\autodoc:parameter{color=<color specification>} sets the background of the current and all following pages to that color. The color specification has the same syntax as specified in the \autodoc:package{color} package.}
+\item{\autodoc:parameter{src=<file>} sets the backgound of the current and all following pages to the specified image. The latter will be scaled to the target dimension.}
+\end{itemize}
+
+The background extends to the page trim area (“page bleed”) if the latter is defined.
+This is to ensure that it indeed “bleeds” off the sides of the page, so as to avoid thin white lignes on an otherwise full color page when the paper sheet is cut to dimension but some pages are trimmed slightly more than others.
+If setting only the current page background different from the default is desired, an extra parameter \autodoc:parameter{allpages=false} can be passed.
 
 \background[color=#e9d8ba,allpages=false]
 
 So, for example, \autodoc:command{\background[color=#e9d8ba,allpages=false]} will set a sepia tone background on the current page.
+The \autodoc:parameter{disable=true} parameter allows disabling the background on the following pages.
+It may be useful when \autodoc:parameter{allpages} is active from a previous invocation.

 The \autodoc:package{dropcaps} package allows you to format paragraphs with an “initial capital” (also commonly referred as a “drop cap”), typically one large capital letter used as a decorative element at the beginning of a paragraph.
 
 It provides the \autodoc:command{\dropcap} command.
@@ -92,6 +177,18 @@ To tweak the position of the dropcap, measurements may be passed to the \autodoc
 Other options passed to \autodoc:command{\dropcap} will be passed through to \autodoc:command{\font} when drawing the initial letter(s).
 This may be useful for passing OpenType options or other font preferences.
 
+Some fonts have capitals — such as, typically, \autodoc:example{Q} and \autodoc:example{J} — hanging below the baseline.
+By default, the dropcap fits the specified number of lines and the characters are typeset in a smaller size to fit these descenders.
+
+With the \autodoc:parameter{strict=false} option, the characters are scaled with respect to their height only, and extra hanged lines are added to the dropcap in order to accommodate the descenders.
+The dropcap is allowed to overflow the baseline by a reasonable amount, before triggering the addition of extra lines, for fonts that have capitals very slightly hanging below the baseline.
+This tolerance is computed based on the font metrics.
+If you want to bypass this mechanism and adjust the tolerance, you can use the \autodoc:setting{dropcaps.bsratio} setting.
+
+Moreover, some fonts, such as EB Garamond Initials, have \em{all} capitals hanging below the baseline.
+To take this case into account in non-strict mode, the depth adjustment of the dropcap is empirically corrected based on that of a character which shouldn't have any, by default an \autodoc:example{I}.
+The character(s) used for this depth adjustment correction can be specified using the \autodoc:parameter{depthadjust} option.
+
 \begin{autodoc:note}
 One caveat is that the size of the initials is calculated using the default linespacing mechanism.
 If you are using an alternative method from the \autodoc:package{linespacing} package, you might see strange results.

+\begin{document}
+
+From time to time, the default behavior of a function or value of a setting in SILE might change with a new release.
+If these changes are expected to cause document reflows they will be noted in release notes as breaking changes.
+That generally means old documents will have to be updated to keep rending the same way.
+On a best-effort basis (not a guarantee) this package tries to restore earlier default behaviors and settings.
+
+For settings this is relatively simple.
+You just set the old default value explicitly in your document or project.
+But first, knowing what those are requires a careful reading of the release notes.
+Then you have to chase down the incantations to set the old values.
+This package tries to restore as many previous setting values as possible to make old documents render like they would have in previous releases without changing the documents themselves (beyond loading this package).
+
+For functions things are a little more complex, but for as many cases as possible we'll try to allow swapping old versions of code.
+
+None of this is a guarantee that your old document will be stable in new versions of SILE.
+All of this is a danger zone.
+
+From inside a document, use \autodoc:command{\use[module=packages.retrograde,target=%s]} to load features from SILE %s.
+
+This can also be triggered from the command line with no changes to a document:
+
+\begin{autodoc:codeblock}
+$ sile -u 'packages.retrograde[target=%s]'
+\end{autodoc:codeblock}
+
