+## 2021-05-02
+
+This release brings a long overdue redesign of the workflow for
+editors and translators. My hope is that users won't need to change
+their bibliography databases, but I did need to change one example in
+the user guide, moving an editor name list from a child entry to its
+parent, where it belonged in the first place. In all, the changes
+greatly extend the control and flexibility that users have over the
+placement of editors and translators while allowing for simpler
+internals.
+
+* highlights pertaining to editors and translators:
+
+  - added support for the following editorial roles:
+
+    + expanded by...
+    + expanded and compiled by...
+    + expanded and edited by...
+    + expanded and revised by...
+    + expanded and translated by...
+    + expanded and updated by...
+    + compiled and expanded by...
+    + edited and expanded by...
+    + revised and expanded by...
+    + translated and expanded by...
+    + updated and expanded by...
+
+  - added support for translators of `issuetitle` and `series`, which
+    means you may assign translators to every title to which you may
+    assign editors
+  - editor and translator type fields now accept comma-separated
+    bibliography strings, making all editorial roles available for
+    `issuetitle`, `maintitle`, and `series` (e.g. if `editor` is the
+    reviser of `maintitle`, put `maintitle,reviser` or
+    `reviser,maintitle` in `editortype`)
+  - added `swaptrans:issuetitle`, `swaptrans:maintitle`, and
+    `swaptrans:series` entry options to swap positions of editors and
+    translators of `issuetitle`, `maintitle`, and `series`
+  - for special circumstances (explained in the user guide), added
+    three more entry options for swapping editors and translators:
+    `swaptrans:title`, `swaptrans:booktitle`, and
+    `swaptrans:bookbooktitle`
+  - added support for printing a second tier of editors after `title`,
+    `issuetitle`, `maintitle`, and `series` (e.g. "Edited by Jane Doe.
+    Revised and Expanded by John Smith")
+  - if the editors and translators of a work are the same, you can
+    control the assignment in several ways, including with just one
+    name list and its corresponding type field (e.g. if Jane Doe is
+    the compiler and translator of `title`, you can, among other
+    options, put `Doe, Jane` in `editor` and `comptrans` in
+    `editortype` or `Doe, Jane` in `translator` and `comptrans` in
+    `translatortype`)
+  - fixed several issues, at least, affecting the placement of
+    editors and translators, mainly the latter
+
+* added preamble option `shortafter` to print the same output as the
+  preamble option `short` but with long first citations
+* for works in certain collections, fixed punctuation after the
+  `edition` field
+
 ## 2021-01-30
 
 * added support for the `pubstate` field to indicate when a work is

 \subsection{Types of Editors and Translators}
-\label{edtransnames}
 
-For the most part, Windy City associates the \bibfield{editor} and
-\bibfield{translator} fields with the lowest level title within the
-scope of an entry. In most cases, then, you can assign editors and
-translators simply by adding the \bibfield{editor} and
-\bibfield{translator} fields to a database entry. The entry below is
-an example from \textit{CMOS} \ref{14.104}:
+Windy City has four name lists for editors (\bibfield{editor},
+\bibfield{editora}, \bibfield{editorb}, and \bibfield{editorc}) and
+three name lists for translators (\bibfield{translator},
+\bibfield{translatora}, and \bibfield{translatorb}). At points where
+it's prepared to print them, it cycles through one or both sets of
+lists, depending on the context, looking for names to print. The set
+of editors starts with \bibfield{editor}, followed by
+\bibfield{editora}, and so on. The set of translators starts with
+\bibfield{translator}, followed by \bibfield{translatora}, and so on.
+Editors precede translators, unless you reverse the order with a
+\opt{swaptrans} entry option (see section \ref{editors:swap}). Within
+each set, the style prints the first name list that meets its criteria
+for that context. Apart from exceptions discussed below, you can
+assign any editor or translator name list to any \bibfield{title},
+\bibfield{issuetitle}, \bibfield{maintitle}, or \bibfield{series}.
+
+\subsubsection{The Basics}
+\label{editors:basics}
+
+In most cases, you'll assign editors and translators to a
+\bibfield{title}. Since it's the default assignment, you can do this
+just by adding the \bibfield{editor} and \bibfield{translator} fields
+to a database entry. The entry below is an example from \textit{CMOS}

+For editors and translators with more than two roles per title, you
+need to print more than one name list, either an editor name list and
+a translator name list or two editor names lists (see the previous
+discussion of second tier editors). This allows for complex
+assignments such as ``Edited and Translated by Jane Doe. Revised and
+Updated by Jane Doe and John Smith.'' What's not allowed is listing
+three or more roles at once, as in ``Edited, Translated, and Revised
+by Jane Doe.''
+
+\subsubsection{Other Options and Titles}
+\label{editors:other}
+
+Windy City simplifies the assignments of editors and translators in
+several ways. For one, the default assignment of every editor name
+list is \textit{editor}, and the default assignment of every
+translator name list is \textit{translator}. As a result, you never
+need to use the values \textit{editor} or \textit{translator} in the
+type fields. It's strictly optional. The name fields alone set the
+correct assignment.
+
+Much the same holds when the editor and translator of a work are the
+same. The usual way to set this assignment is with identical name
+lists:
+
+\begin{verbatim}
+   editor = {Doe, Jane},
+   translator = {Doe, Jane},
+\end{verbatim}
+
+\noindent This gives a default assignment of \textit{editor and
+translator} (\textit{edtrans} from Table \ref{editors:table}), unless you
+use the appropriate \opt{swaptrans} entry option, which gives
+\textit{translator and editor} (\textit{transed} from Table
+\ref{editors:table}). No editor or translator type field is necessary.
+
+When type fields are required, Windy City offers flexibility over how
+you structure your bibliography entries: If you like, you can set the
+assignment with just one editor or translator type field and its
+corresponding name field, or with both name fields and one type field,
+or with both name fields and both type fields. To set Jane Doe as the
+compiler and translator of a \bibfield{title}, Windy City treats all
+five options below as equivalent:
+
+\begin{enumerate}[itemsep=0.2\baselineskip]
+
+\item
+
+\begin{verbatim}
+   editor = {Doe, Jane},
+   editortype = {comptrans},
+\end{verbatim}
+
+\item
+
+\begin{verbatim}
+   translator = {Doe, Jane},
+   translatortype = {comptrans},
+\end{verbatim}
+
+\item
+
+\begin{verbatim}
+   editor = {Doe, Jane},
+   translator = {Doe, Jane},
+   editortype = {comptrans},
+\end{verbatim}
+
+\item
+
+\begin{verbatim}
+   editor = {Doe, Jane},
+   translator = {Doe, Jane},
+   translatortype = {comptrans},
+\end{verbatim}
+
+\item
+
+\begin{verbatim}
+   editor = {Doe, Jane},
+   translator = {Doe, Jane},
+   editortype = {comptrans},
+   translatortype = {comptrans},
+\end{verbatim}
+
+\end{enumerate}
+
+The last option above raises the possibility that editor and
+translator type fields may conflict. What if the editor type is
+\textit{comptrans} and the translator type is something else, say,
+\textit{extrans}? If the editors and translators are the same, but the
+type fields differ, Windy City reads the editor type field and ignores
+the translator type field.
+
+Three more values for type fields allow you to assign editors and
+translators to \bibfield{issuetitle}, \bibfield{maintitle}, and
+\bibfield{series}. Here's an example from \textit{CMOS}
 \ref{14.123}:

-\noindent If there were no \bibfield{editortype} assigning the editor
-to the series, the output would list a book's editor. In short, for a
-title's compilers, revisers, and updaters and for any title at a
-higher level than \bibfield{title}, you need to use
-\bibfield{editortype}. Combined with Windy City's support for citing
-articles, chapters, books, and other works within books, this scheme
-allows for several sets of editors per work, although it does limit
-you to just one set of compilers, revisers, and updaters.
-
-What about translators? Unless a work's bibliography database entry
-has a \bibfield{translatortype} field with the value
-\textit{maintitle}, Windy City associates the names in
-\bibfield{translator} with the entry's lowest level title. (Recall
-``The Ascent of Mont Ventoux'' above.) You should rarely, and perhaps
-never, need more than one set of translators per work. But if you do,
-Windy City lets you assign as many as three---as long as you
-cross-reference a work with one set of translators to another with
-two.
-
-The style has three other name lists for editors: \bibfield{editora},
-\bibfield{editorb}, and \bibfield{editorc}. If a work has more than
-one set of editors, list editors of the lowest level title in
-\bibfield{editor}. Usually, those are editors of a \bibfield{title}.
-The next level up, as it were, is for \bibfield{editora}, followed by
-\bibfield{editorb}, then \bibfield{editorc}. Remember to include the
-appropriate \bibfield{type} field to indicate an editor's role. These
-fields are \bibfield{editortype} (for \bibfield{editor}),
-\bibfield{editoratype} (for \bibfield{editora}),
-\bibfield{editorbtype} (for \bibfield{editorb}), and
-\bibfield{editorctype} (for \bibfield{editorc}).
-
-As it happens, Windy City puts a lot of effort into sorting out where
-to print the names of editors and translators, so it's a bit more
-clever than the previous paragraph suggests. In particular, if you use
-\bibfield{editortype} to assign an \bibfield{editor} to a
-\bibfield{maintitle} or some other higher level title, and have an
-\bibfield{editora} with no corresponding \bibfield{editoratype}, Windy
-City will assume that \bibfield{editora} is the editor of the
-\bibfield{title}. Regardless, the best practice is to the follow the rule
-of thumb described above, reserving \bibfield{editor} for
-\bibfield{title} and working up from there.
+\noindent If there were no \bibfield{editortype} with the value
+\textit{series}, the style would have assigned \bibfield{editor} to
+\bibfield{title}. The same goes for \bibfield{issuetitle} and
+\bibfield{maintitle}: Assign editors and translators to them by
+putting \textit{issuetitle} and \textit{maintitle} in the relevant
+type fields.
+
+With the help of strings from Table \ref{editors:table}, all editor and
+translator types are available to \bibfield{issuetitle},
+\bibfield{maintitle}, and \bibfield{series}. Commas function as
+delimiters. To take the previous example, you could list Catharine
+Stimpson as the editor and compiler of the series by putting the
+values \textit{series,edcomp} or \textit{edcomp,series} in
+\bibfield{editortype}.
+
+Almost any entry that relies on cross-referencing can be written
+without it. Doing so, however, requires some fields in your
+bibliography database that are usually meant for the style's internal
+use. These fields include \bibfield{booktitle} (a cross-referenced
+\bibfield{title}) and \bibfield{bookbooktitle} (a double
+cross-referenced \bibfield{title}---a \bibfield{title}
+cross-referenced by a cross-referenced \bibfield{title}). To
+accommodate entries that don't use cross-referencing, the style
+accepts the values \textit{booktitle} and \textit{bookbooktitle} in
+editor and translator type fields. An example of double
+cross-referencing will set us up to use both:
+
+\begin{verbatim}
+   @InCollection{doe2018,
+     options = {swapvol},
+     author = {Doe, Jane},
+     title = {A Poem},

+
+\noindent The following alternative dispenses with \bibfield{crossref}
+but needs two editor type fields, plus two other fields that don't
+usually appear in bibliography databases: \bibfield{bookvolume} (a
+cross-referenced \bibfield{volume}) and \bibfield{bookyear} (a
+cross-referenced \bibfield{year}).

+
+In short, for a title's compilers, expanders, revisers, and updaters,
+and for any title other than \bibfield{title}, you need to put the
+correct value of the assignment in the editor or translator type field
+that corresponds with the editor or translator name list
+(\bibfield{editortype} for \bibfield{editor},
+\bibfield{translatortype} for \bibfield{translator}, and so on).
+Combined with Windy City's support for citing articles, chapters,
+books, and other works within books, this scheme allows for several
+sets of editors per work.
 
 \subsection{Switching Places and Roles}
-\label{edtranspos}
+\label{editors:swap}
+
+According to \textit{CMOS}, if a work has an editor and a translator,
+their names should appear in citations in the order in which they
+appear on the work's title page (see \textit{CMOS} \ref{14.104}). By
+default, the style lists editors first. To reverse the order, the
+style provides a suite of entry options that apply to the editors and
+translators of different titles. This means that if a work has
+multiple sets of editors and translators, you may swap positions of
+any set without affecting the others.
 
-Normally, Windy City lists editors first. But if translators are

+
+As often happens, cross-referencing raises some complications. The
+problem is that \opt{swaptrans} applies to the editors and translators
+of a \bibfield{title}, but cross-referenced works have more than one

+even a double cross-referenced \bibfield{title}). Three more entry
