+# RELEASE NOTES FOR VERSION 3.17
+- **INCOMPATIBLE CHANGE**
+  The behaviour of index-less granular xdata references to list fields has
+  changed. Before, a reference to an XDATA list field would select the
+  first element in the XDATA field list if no index was given but now this
+  will splice in all elements of the XDATA list field. To ensure the
+  previous behaviour, simply add "-1" (assuming the default value of "-"
+  for the biber 'xdatasep' option) to the end of all granaular list
+  XDATA references.
+- Added helper macros to enable calculations with non-ASCII numerals.
+  This is necessary to properly support languages like Marathi.
+  At the moment the 'translation' is very basic and uses a one-to-one
+  correspondence of US-ASCII (Arabic) digits and non-ASCII digits.
+  The translation also needs additional post-processing steps.
+  Use `\blx@defcomputableequivalent{<numeral digit>}{<ASCII digit>}` to
+  make `<numeral digit>` an equivalent of `<ASCII digit>`
+  (presumably this command will be used in `.lbx` files if the language
+  requires it).
+  `\hascomputableequivalent{<string>}` can be used to check if `<string>`
+  is a number that can be converted to a number with ASCII digits.
+  `\getcomputableequivalent{<string>}{<macro>}` does the conversion
+  and saves the number in `<macro>`.
+  There is `\ifiscomputable{<string>}` to check if a `<string>`
+  is an ASCII number OR has a computable equivalent.
+  There are analogous macros for fields instead of strings.
+- Added `\textouterlang` to select the last active language that
+  was not selected by `biblatex` itself.
+  This may help in multilingual setups where `biblatex` also changes the
+  language quite heavily.
+- Added `\DeclareBibstringSet`, `\DeclareBibstringSetFormat` etc.
+  to allow injecting additional formatting for a set of bibstrings.
+  Sets can be defined arbitrarily. These commands are primarily
+  intended for use in localisation modules.
+- Changed the definition of `\bibnamedelimi` to `\isdot\addnbspace`.
+  Previously the definition was just `\addnbspace`, which meant the `.`
+  would be treated as a period/full stop.
+- **BREAKING CHANGE**
+  `\DeclareDelimFormat` no longer accepts a list of names as argument.
+  It only accepts a single delimiter name.
+  A list of contexts is still supported.
+  Note that previously the optional argument would not work correctly
+  with a list of names.
+- **CRITICAL CHANGE**
+  `biblatex` no longer writes tracking and refsection initialisation code
+  to aux files.
+  Instead the `\...cite` commands are redefined locally to do that on demand.
+  This should keep the auxiliary files much cleaner of `biblatex`
+  intervention.
+- **CRITICAL CHANGE**
+  Generalised `season` date part to `yeardivision`. It can now also
+  hold quarter, quadrimester, semestral or seasons with hemisphere
+  designation.
+  Helper macros have been renamed accordingly. Limited backwards
+  compatibility is in place.
+- **(Possibly) CRITICAL CHANGE**
+  `\notecite` and friends no longer issue an explicit `\nocite`.
+  Since the commands are defined with `\DeclareCiteCommand`, they
+  already issue a normal cite request.
+  The additional `\nocite` from the loop code was superfluous
+  and would result in slightly instable `.bcf` files.

As a rule of thumb \bibfield{number} is the right field in most circumstances. In the standard styles \bibfield{number} modifies \bibfield{volume}, whereas \bibfield{issue} modifies the date (year) of the entry. Numeric identifiers and short designators that are not necessarily (entirely) numeric such as <A>, <S1>, <C2>, <Suppl.\ 3>, <4es> would go into the \bibfield{number} field, because they usually modify the \bibfield{volume}. The output of---especially longer---non-numeric input for \bibfield{number} should be checked since it could potentially look odd with some styles. The field \bibfield{issue} can be used for designations such as <Spring>, <Winter> or <Michaelmas term> if that is commonly used to refer to the journal.

 \subsubsection{Active Characters in Bibliography Headings}
 \label{use:cav:act}
 
-Packages using active characters, such as \sty{babel}, \sty{polyglossia}, \sty{csquotes}, or \sty{underscore}, usually do not make them active until the beginning of the document body to avoid interference with other packages. A typical example of such an active character is the Ascii quote |"|, which is used by various language modules of the \sty{babel}/\sty{polyglossia} packages. If shorthands such as |"<| and |"a| are used in the argument to \cmd{defbibheading} and the headings are defined in the document preamble, the non-active form of the characters is saved in the heading definition. When the heading is typeset, they do not function as a command but are simply printed literally. The most straightforward solution consists in moving \cmd{defbibheading} after |\begin{document}|. Alternatively, you may use \sty{babel}'s \cmd{shorthandon} and \cmd{shorthandoff} commands to temporarily make the shorthands active in the preamble. The above also applies to bibliography notes and the \cmd{defbibnote} command.

 The entry key of an item in the \file{bib} file. This is the string used by \biblatex and the backend to identify an entry in the \file{bib} file.
 
 Note that the set of characters allowed and usable in the string for \bibfield{entrykey} depends on the backend (\biber, \bibtex) as well as the \latex engine (\pdflatex, \lualatex, \xelatex).
-Generally, ASCII-letters (\texttt{a-z}, \texttt{A-Z}) and numbers (\texttt{0-9}) are safe, so are the punctuation characters full stop (\texttt{.}) and solidus (\texttt{/}). The punctuation characters \texttt{-\_:;!?} are also safe even if they are made active by \sty{babel}/\sty{polyglossia}. If a Unicode engine is used, non-ASCII characters are also acceptable.
+Generally, \acr{US-ASCII}-letters (\texttt{a-z}, \texttt{A-Z}) and numbers (\texttt{0-9}) are safe, so are the punctuation characters full stop (\texttt{.}) and solidus (\texttt{/}). The punctuation characters \texttt{-\_:;!?} are also safe even if they are made active by \sty{babel}/\sty{polyglossia}. If a Unicode engine is used, non-\acr{US-ASCII} characters are also acceptable.
 Curly braces (\texttt{\{\}}), commas, spaces, backslashes (\texttt{\textbackslash}), hashes (\texttt{\#}), percent characters (\texttt{\%}) and tildes (\texttt{\textasciitilde}) are always forbidden. \biber additionally forbids round brackets (\texttt{()}), quotation marks (\texttt{\textquotedbl}, \texttt{\textquotesingle}), and the equals sign (\texttt{=}).
 The \bibfield{entrykey} is case sensitive, but it is not recommended to exploit that fact too much by introducing two different entries whose key differs only in capitalisation (\eg\ \texttt{sigfridsson} and \texttt{Sigfridsson}).
-For full portability it is advisable to stick to a scheme of lowercase (and if so desired uppercase) ASCII-letters, numbers and a small set of acceptable punctuation characters, say \texttt{.:-}.

 Here, a clone of an entry from the specified data source will be created. The entry key of the clone will be the same as the original but prefixed by the value of the \texttt{entryclone} parameter. The cloned entry would still need to be cited in the document using its new entry key. This type of mapping step should be used with care as it may produce labelling problems in authoryear styles which use, for example, \opt{extradate}. One use case is for numeric styles which contain multiple bibliographies containing the same entry. In this case, you may need different bibliography number labeld for the same entry and this is very tricky when there is only one entry which needs different labels. Creating clones with different entry keys solves this problem.

The \prm{elements} are an undelimited list of \cmd{field}, \cmd{literal}, and \cmd{citeorder} commands which are evaluated in the order in which they are given. If an element is defined, it is added to the sort key and the sorting routine skips to the next \cmd{sort} directive. If it is undefined, the next element is evaluated.

+The \cmd{citecount} element has a special meaning. It requests a sort based on the number of times an item was cited. The standard \texttt{count} sorting template uses this to provide a sort in descending order of number of citations. Note that the option \opt{citecounter} must also be enabled for this to work. In addition, an additional \biber run is required in order to calculate the data for this option correctly and so the typical invocation sequence for this option is \emph{latex}$\rightarrow$\emph{biber}$\rightarrow$\emph{latex}$\rightarrow$\emph{latex}$\rightarrow$\emph{biber}$\rightarrow$\emph{latex}.

It is also better equipped to deal with non-\acr{US-ASCII} input and macros than the \opt{latex2e} implementation. \cmd{MakeSentenceCase} behaves as follows.
 \begin{itemize}\setlength{\labelsep}{1em}

-  
+
   Note that with the \opt{latex2e} code a pair of braces that starts with a control sequence will be treated as a single character for capitalisation purposes. This means that the entire argument of a command protected with a single pair of braces is capitalised.
   \item With the \opt{latex2e} code expandable commands are expanded before the case change, which means that the case change applies to the replacement text. Unexpandable commands are not touched.
-  
+
   \bibtex does not interpret macros and therefore passes commands through unchanged (this does not necessarily apply to the \emph{arguments} of those commands). The \opt{expl3} implementation also does not expand commands and only applies case change to the arguments.
   \item Text wrapped in one or more pairs of braces is protected from case change \emph{unless} it starts with a control sequence. This is the same behaviour as with \bibtex. Note that the braces could either be explicit groups or argument delimiters.
   \item Text in a single pair of braces that starts with a control sequence is not protected and will be subject to case changes. Note that this need not apply to braces that are argument delimiters, in fact the \opt{latex2e} implementation of \cmd{MakeSentenceCase} may in some cases produce an error or otherwise undesirable output if the argument of a command starts with a control sequence. \bibtex's case change function does not differentiate between argument delimiters and brace groups and always subjects text at brace level~1 to case change if it starts with a control sequence.

+Bibliography string sets can be useful to apply additional formatting to a number of bibliography strings at the same time. These commands are intended for use in language modules. For example in French typography it is customary to italicise Latin terms. The French language module can define a new bibliography string set called \texttt{latin} for all Latin strings and apply additional formatting only to these strings. It is not recommended to apply the formatting dierctly in the bibliography string definitions, since that can interfere with the capitalisation function.
