$Id: RELEASE,v 0.7 2007/12/09 14:52:00 lehman beta $ RELEASE NOTES FOR VERSION 0.7 The changelog of this release is the longest list of changes in any biblatex release so far. Skimming the full list in biblatex.pdf is highly recommended. In the following, I will focus on changes 'under the hood' which are not mentioned in the changelog, point out things which may break backwards compatibility, and comment on some improvements which may not be immediately obvious from looking at the changelog because they pertain to a set of changes rather than a single one. * Roadmap I will take a break from biblatex development until summer 2008. That's in part because my time budget for LaTeX hacking is severely restricted. And in part it's because the user and author interface of the package is considered stable now, so the current phase of development is a good opportunity for style authors to test the current feature set with some real-world applications before the final 1.0 release. If all goes according to plan, version 0.8 will mainly be a consolidation release with bug fixes and minor improvements. If any serious bugs come up in the meantime, I'll try to fix them right away. * User and author interface stable Starting with this release, the user and author interface of this package may be considered as stable. This means that I will try to refrain from making syntactically or functionally incompatible changes to the core package, unless I'm forced to do so because of a bug or because one of the most recently added features turns out to be really awkward. Essentially, citation and bibliography styles written for this version should work with biblatex 1.0 with no or at most minor modifications. Please note that this is a development aim, but there is no guarantee. Also note that the definitions in biblatex.def (mainly the formatting directives) are not guaranteed to be stable at this point. In other words: if you use the default definitions, your style will inherit possible improvements in future versions. If you use modified formatting directives, you may need to update them to integrate new functions. That should be fairly easy, though. * CTAN staging area for biblatex styles There's a new location for contributed biblatex styles, it's: macros/latex/exptl/biblatex-contrib/ Contributed styles should go into a subdirectory of the above location. E.g., a style called 'MLA' would go into: macros/latex/exptl/biblatex-contrib/mla/ Note that the exptl/ subtree is intended for experimental or beta code. As soon as biblatex hits 1.0 and moves out of exptl/ to macros/latex/biblatex/ there's be a corresponding biblatex-contrib. At this point, all contributed styles should be considered experimental because the core package is still in beta. * Removed biblatex.cbx and biblatex.bbx I've removed the files biblatex.cbx and biblatex.bbx from the distribution. The code formerly found in biblatex.cbx has been moved to biblatex.def. The code formerly found in biblatex.bbx has been split up. The most generic parts have been moved to biblatex.def. The less generic parts, which are closely tied to biblatex's standard bibliography style, are now part of standard.bbx. I've also rearranged some of the bibmacros formerly found in the above files and renamed some of them. If you have been using some of that code in a custom bibliography style, don't worry, all the code is still there, but parts of it may be arranged differently (e.g., a bibmacro may have been split up into two macros or two macro may have been merged into one) and the names of some bibmacros may have changed. Note that biblatex.def is always loaded, but standard.bbx is not. If you have been using code which is now part of standard.bbx in a custom bibliography style, you need to copy the relevant parts to your style. * New dependency on etoolbox.sty Some of the most generic parts of biblatex.sty have been moved to an independent package called 'etoolbox', which is now required. The package is available from CTAN and may also be useful for style authors. * Type-specific formatting directives All formatting directives may now be defined on a per-type basis; e.g.: \DeclareFieldFormat[article]{title}{\mkbibquote{#1}} would define the format of the 'title' field of @article entries only. The fallback mechanism for formats now works as follows. The command \printfield{title}, when used in an @article driver, would check for the following formats (in this order): title [article] title default This also applies to cases where a specific formatting directive is requested explicitly, i.e. \printfield[myformat]{title}, would check for these formats: myformat [article] myformat default The point is that you can override formats on a per-type basis without having to hack any drivers. * Truncation with 'and others' now supported by literal lists Truncating a list with 'and others' in the .bib file is now supported by both name lists and literal lists. This used to be specific to name lists. See \ifandothers and \ifmoreitems as well as \finallistdelim and \andmoredelim for details. * Introducing entry options and style-specific options This release introduces the concept of an entry option and a new 'options' field. The 'useprefix' field has been replaced by an entry option. Instead of: useprefix = {true} you now use options = {useprefix=true} There are two more predefined entry options called 'useauthor' and 'useeditor'. These options may still be used globally to set the default behavior. In addition to that, Bibliography and citation styles may define additional package and entry options. See \DeclareEntryOption and \DeclareBibliographyOption for details. * Introducing multicite commands This release introduces an entirely new class of citation commands called 'multicite' commands. The point of a multicite command is that its argument may be a fully qualified list of citations where each key has its own pre- and postnote. The syntax is straightforward. Instead of: \cite[See][55]{key1}; \cite[12]{key2}; \cite[93]{key3} you can now say: \cites[See][55]{key1}[12]{key2}[93]{key3} This is particularly useful with parenthetical citations and citations given in footnotes. It's also possible to assign a pre- and/or postnote to the entire list. These global notes are given in parentheses: \footcites(See)(and chapter 3)[55]{key1}[12]{key2}[93]{key3} See \cites, \parencites, \footcites, etc. in the manual. There is also an \autocites command (a multicite version of \autocite). Defining new multicite commands is very easy because they are based on the regular citation commands. See the documentation of \DeclareMultiCiteCommand for details. * Improved trackers and tracking control The 'trackers' provided by biblatex have been greatly improved and extended. This release also adds new trackers which correspond to the requirements of some common citation styles. See the package options 'pagetracker', 'citetracker', 'ibidtracker', 'opcittracker', and 'loccittracker' for all the gory details. Also see \ifciteibid, \ifopcit, and \ifloccit. It's possible to control tracking in the document, see \pagetrackertrue/false and \citetrackertrue/false for details. Note that text commands like \citetitle are now exluded from tracking by default. See also the point below. * Tracker reset support It's possible to reset trackers and citation styles and several different levels. For the built-in trackers, see the package option 'citereset' as well as the user-level command \citereset. For style-specific reset support, see \InitializeCitationStyle, \InitializeBibliographyStyle, \OnManualCitation, and the user-level command \mancite. * New entry types, more custom entry types This release adds the entry types 'periodical' and 'patent', which are fully supported by the standard styles. Several new custom types have also been added. The custom types are not supported by default, but they may be useful in custom styles. * New field/list subtype: key field/list I've introduced a new field/list data subtype called key field/key list. They may hold printable data or localization keys and work as follows: A test is performed to determine whether the value of the field is a known localization key. If so, the localized string is printed. If not, the value is printed as is. * Improved postnote handling, alternative pagination schemes The handling of page numbers in the 'pages' field and in the postnote argument to citation commands has been improved significantly. Biblatex does range detection now and recognizes Roman numerals as numbers. It also supports alternative 'pagination' schemes (columns, line or verse numbers, etc.). See the fields 'pagination' and 'bookpagination' and related pointers in the changelog. See also \mkpageprefix, \ppspace, \pno, \ppno, \nopp, \psq, \psqq. * Support for unique names in citations This release introduces support for unique names in citations. Some author-year and author-title citation styles require unambiguous names in citations. For example, with entries such as John Smith 1995 Edward Smith 1995 citations would be rendered as J. Smith 1995 E. Smith 1995 rather than Smith 1995a Smith 1995b See the package option 'uniquename' and the special counter 'uniquename' for details. Note that this feature is now enabled by default in the following styles: authoryear, authoryear-comp, authortitle-terse, authortitle-tcomp. * Improved support for numeric labels The 'defernums' package option addresses the problem of discontinuous numbering when using a numeric style in combination with bibliography filters. If this option is enabled, the numeric labels are assigned the first time an entry is printed in any bibliography. This is similar to the traditional algorithm used by LaTeX to assign numeric labels. * Alternative, non-inheriting cross-referencing mechanism This release introduces an alternative cross-referencing mechanism which does not inherit any data. It's useful in styles which format cross-referenced entries differently. See the description of the field 'xref' and related pointers in the manual. * Support for different encodings Biblatex is now capable of handling .bib files with an encoding which is different from the encoding of the .tex file. See the 'bibencoding' package option for details. * More robust handling of citation keys This release adds some normalization code which deals with special characters in citation keys. A typical example are keys which contain an underscore. This should be much more robust now. * Renamed fields The 'journal' field has been renamed to 'journaltitle' but the old name is still supported as an alias. There's also a 'journalsubtitle' field and fields for the title and the subtitle of a single issue. In other words, article entries now support a complete set of titles similar to inbook-like entry types: journaltitle/issuetitle/title essentially correspond to maintitle/booktitle/title. The field name 'id' turned out to be incompatible with JabRef. Apart from that, the name is a bit too generic for what this field holds anyway. It's called 'eid' now (electronic ID) and holds an article ID used by online journals or journals which are also available online. * 'labelctitle' replaced by 'singletitle' The 'labelctitle' field has removed in favor of a different mechanism using a test called \ifsingletitle. The package option 'labelctitle' has also been renamed to 'singletitle'. * Alphabetic label now configurable The alphabetic label provided in the 'labelalpha' field is now configurable to a certain extend. It is responsive to the global package options 'maxnames' and 'minnames'. It's also possible to influence the handling of truncated labels by redefining \labelalphaothers. * Name types This release introduces the concept of a name type. This is best explained by example. Suppose a book has a compiler rather than an editor. In previous versions of this package, there was no way to override the string 'editor' and 'edited by'. Starting with this release, you may specify 'compiler' as an editor type: @book{..., editor = {...}, editortype = {compiler}, Supported editor types are 'editor' (the default) and 'compiler'. Note that this mechanism is hooked up to bibliography strings hence it may be extended. See the fields 'authortype', 'editortype', and 'name[a-c]type' in the manual. * Consistent set of wrappers I've completed the generic wrapper commands provided by biblatex so that they form a complete set. Instead of using the solution in the left column of the following list, use the wrapper in the right column: (...) -> \mkbibparens{...} [...] -> \mkbibbrackets{...} \footnote{...} -> \mkbibfootnote{...} \textsuperscript{...} -> \mkbibsuperscript{...} \emph{...} -> \mkbibemph{...} \enquote{...} -> \mkbibquote{...} ``...'' -> \mkbibquote{...} The wrappers integrate much better with biblatex and they also provide additional features. * New citation styles, some styles renamed I've renamed all verbose citation styles from 'authortitle-*' to 'verbose-*' and added some new styles. See the changelog for details. * natbib compatibility style To facilitate the move from natbib to biblatex, this release adds a special natbib compatibility style which maps natbib's core citation commands to equivalent biblatex commands. See the package option 'natbib' for details. * All citation commands scan ahead for punctuation Starting with this release, all citation commands scan ahead for punctuation to avoid double punctuation at the end of a citation. This used to be a feature exclusive to \autocite. The 'autopunct' package option and the \DeclareAutoPunctuation command will now affect all citation commands, not only \autocite. * Support for font style adaptation of punctuation This release implements an alternative way of dealing with punctuation after a field printed in a different font (for example, a title printed in italics). The standard (La)TeX way of dealing with this problem is to add a small amount of space (the so-called italic correction) to avoid clashes between the final letter of a word in italics and the following (upright) punctuation mark. Biblatex is now capable of adapting the punctuation to the font of the preceeding field. See '\mkbibemph' and '\setpunctfont' for details. Note that this feature is experimental. It may very well have a few quirks. Also note that it is disabled by default. Use the 'punctfont' package option to enable it. * Extended language support: Norwegian, Danish This release comes with a norsk.lbx and a danish.lbx file. The translations were contributed by Johannes Wilm. RELEASE NOTES FOR VERSION 0.6 * Style-independent citations This release introduces a special command for style-independent citations. The idea behind the \autocite command is to provide higher-level citation markup which makes global switching from inline citations to citations given in footnotes (or as superscripts) possible. The \autocite command is built on top of lower-level commands like \parencite and \footcite. The citation style provides an \autocite definition by way of \DeclareAutoCiteCommand. This definition may be activated by way of the 'autocite' package option. See the documentation of \autocite in the manual for further details. * Forcing capitalized name prefixes One thing that's been on my personal wishlist for some time is an equivalent to natbib's \Citet command. This release finally introduces additional citation commands which force capitalized name prefixes (provided that there is a prefix and that it is to be printed as part of the citation, i.e. the 'useprefix' option is enabled). The new citation commands are defined as follows in biblatex.cbx: \newcommand*{\Cite}{\bibsentence\cite} \newcommand*{\Textcite}{\bibsentence\textcite} \newcommand*{\Parencite}{\bibsentence\parencite} \newcommand*{\Footcite}{\bibsentence\footcite} \newcommand*{\Citeauthor}{\bibsentence\citeauthor} Here's how it works. Biblatex's punctuation tracker is based on TeX's space factor. All the \bibsentence command does is setting the space factor to a special sentinel value which is detected by \bibstring. The name formatting directive used by all citation commands now incorporates the new \ifcapital test. This test is true if the punctuation tracker would capitalize a bibliography string at this point. If the formatting directive detects the sentinel value, it will capitalize the name prefix (if applicable). A handy side-effect of this approach is that a possible 'prenote' argument is taken into account automatically. For example: '\cite{vandoren}' prints 'van Doren 1995' and '\Cite{vandoren}' prints 'Van Doren 1995' but '\Cite[See]{vandoren}' prints 'See van Doren 1995'. This also works in conjunction with bibliography strings. For example, if the citation style replaces the standard citation by something like '\bibstring{ibid}', then '\cite{vandoren}' prints 'ibid.' but '\Cite{vandoren}' prints 'Ibid.'. In other words, unless the citation style is doing something very unusual, there is no need to define \Cite et al. explicitly with \DeclareCiteCommand. The default definitions should work fine in all normal cases. If the style doesn't print any names but rather numerical or alphabetic citations then nothing is capitalized, so that's no problem either. * Custom filters for \printbibliography See \defbibfilter and the 'filter' option of \printbibliography in the manual. * Support for unsorted bibliographies See the package option 'sorting=none'. * Automatic truncation of literal lists This release introduces the package options 'maxitems' and 'minitems' which are similar to 'maxnames' and 'minnames' but affect literal lists. There are also corresponding (local) options for \printbibliography, \printshorthands, and so on. * Improved support for corporate authors and editors There are two new name lists ('shortauthor' and 'shorteditor') which may be helpful when dealing with corporate authors and editors. Basically, 'author' and 'editor' are used in the bibliography whereas 'shortauthor' and 'shorteditor' are used in citations. The point is that you can give a short form of the name for use in citations. For example: @Type{key, author = {{National Aeronautics and Space Administration (NASA)}}, shortauthor = {NASA}, ... } This will print "NASA" in citations but "National Aeronautics and Space Administration (NASA)" in the bibliography. Note that 'shortauthor' and 'shorteditor' are name lists, not literal fields. This means that corporate names must be wrapped in an additional pair of curly braces. * Improved support for articles: journal series and electronic ID Journal series and article IDs are now catered for by the standard styles (entry type 'article'). Note that the 'articleid' field has been renamed to 'eid'. See the annotated bibliography in the 'examples' directory for examples. * DOI support The 'doi' field is now catered for by the standard styles (complete with hyperlinks). See the annotated bibliography in the 'examples' directory for examples. * Fine-grained control of title formatting Previous versions of this package provided two formatting directives for the title field: 'title' (for entry types like 'book', 'collection', etc.) and 'titlein' (for 'article', 'inbook', 'incollection', etc.). I've enhanced this scheme such that the format of the title may be defined on a per-type basis. In biblatex.def you'll find the following directives for the bibliography: \DeclareFieldFormat{title:book}{\emph{#1}\isdot} \DeclareFieldFormat{title:inbook}{\enquote{#1}\midsentence} ... as well as dedicated directives for the titles in citations: \DeclareFieldFormat{citetitle:book}{\emph{#1}\isdot} \DeclareFieldFormat{citetitle:inbook}{\enquote{#1}\midsentence} ... and in the list of shorthands: \DeclareFieldFormat{lostitle:book}{\emph{#1}\isdot} \DeclareFieldFormat{lostitle:inbook}{\enquote{#1}\midsentence} ... I've updated all generic definitions in biblatex.cbx, biblatex.bbx, and standard.bbx accordingly. Note that the 'title:type' directives are used for both the 'title' and the 'subtitle' field (which are wrapped in a \printtext command controlling the formatting, see the 'title+stitle' bibmacro in biblatex.bbx for an example of how it works). In other words: redefining the 'subtitle' field formatting directive has no effect. * Rearranged localization keys I've rearranged and extended the localization keys quite a bit. This also implies several changes in biblatex.bbx. * Support for KOMA-Script and Memoir The default definitions of the bibliography headings (as defined in biblatex.def) are now automatically adapted for the KOMA-Script classes and the Memoir class. * Improved Spanish support The Spanish localization module now handles the Spanish word 'and' properly ('y' or 'e', depending on the context). * Italian support This release comes with a new italian.lbx file. The translations were contributed by Enrico Gregorio. RELEASE NOTES FOR VERSION 0.5 My original plan for 0.5 was to make minor changes only and focus on fixing bugs. Since only a few issues turned up (memory issues in biblatex.bst), I ended up implementing new things from the wishlist. Please note that the wishlist is closed until after version 1.0. * New author-title citation styles I've added some verbose author-title styles which may be of interest for users in the humanities. The styles are called 'authortitle-verb' and 'authortitle-cverb'. The 'traditional style has been renamed to 'authortitle-trad' and there is an additional new style called 'authortitle-strad'. The styles support shorthands and are fully hyperlinked. The links point to the first, verbose citation instead of the bibliography so these styles may be used without a bibliography, if desired. I've also added a matching 'dummy' bibliography style for every citation style. The dummy style will simply load one of the more generic backend styles. For example, the 'authortitle-verb' style loads the 'authortitle' style. The point is that you may simply use the 'style' package option instead of 'citestyle' plus 'bibstyle'. * Conditional special fields, optimizations in biblatex.bst The special fields 'labelalpha', 'labelctitle', 'labelnumber', and 'labelyear' are conditional now. If a style requires one of those fields, it needs to request them by setting the corresponding package option. E.g., all numeric styles include the line \ExecuteBibliographyOptions{labelnumber} This will instruct biblatex to provide the 'labelnumber' field which is undefined by default now. Making these fields conditional allows for some memory-related optimizations in biblatex.bst. * Author-level support for full citations This version adds an author-level command which makes it possible to execute a bibliography driver in a citation command. See '\rundriver' in the manual. * Page tracker I've implemented a page tracker. The page tracker records the real page on which citations, entries in the bibliography, and entries in the list of shorthands end up. It can work on a per page basis or per double page spread. The page tracker is disabled by default. See the package option 'pagetracker' and the commands '\iffirstonpage' and '\ifsamepage' in the manual. * Unique indentification of reference instances Every 'instance' of a reference is now uniquely identified by a value of the 'citecount' counter. In other words: this counter is incremented for every key processed by any citation command, for every item in the bibliography and for every item in the list of shorthands. This is required by the page tracker but it's also useful if you need to generate a unique anchor name for hyperlinks. * Extended support for hyperlinks I've renamed '\bibhyperlink' to '\bibhyperref' and added generic '\bibhypertarget' and '\bibhyperlink' commands. '\bibhyperref' creates a link from a citation to the corresponding item in the bibliography. '\bibhypertarget' and '\bibhyperlink' are more generic and correspond to the '\hypertarget' and '\hyperlink' commands of the hyperref package. The point here is that you don't need an explicit '\ifhyperref' check. If hyperlinks are disabled, these wrappers will simply pass on their text argument. As an additional benefit, they also provide better anchor placement. The anchors created by '\hypertarget' seem to be located at the baseline, i.e. if you click on a link you get the impression that your PDF viewer jumps to the line of text just below the one you mean. * More name lists See the 'annotator', 'commentator', 'introduction', 'foreword', and 'afterword' lists in the annotated example. * Special fields for indexing See the 'indextitle' and 'indexsorttitle' fields in the annotated example and the indexing examples. * Spanish support This release comes with a preliminary spanish.lbx file. The translations were contributed by Ignacio Fern\'andez Galv\'an. Some advanced features are missing from this file because they are still under scrutiny but it should nevertheless be perfectly funtional. * Examples I've added a biblatex showcase with some example files in the 'examples' subdirectory. There's an example for every citation style and some generic examples demonstrating multiple bibliographies, split bibliographies, indexing, and so on. RELEASE NOTES FOR VERSION 0.4 * Wishlist closed As of this release, the wishlist is closed until after version 1.0. There are already more wishes in the pipeline than I can implement in time for 1.0... RELEASE NOTES FOR VERSION 0.3 The changelog for this release is shockingly long so I'll just point out the general developments behind the individual entries in the changelog. See the full changelog for all the gory details. Note that styles written for version 0.2 will not work with 0.3. * New data type: literal list This release introduces a new data type for literal lists. The point of a literal list is that the list is split up at the 'and' but the individual items are not dissected further. This is intended for fields such as 'location' and 'publisher' since they may contain a list of items but these items are not personal names. I have modified the macro names of the entire data interface for lists to match the change. All macros with the term 'list' in their name are renamed such that 'list' is replaced by 'name(s)'. For example, \printlist is now \printnames, \DeclareListFormat is \DeclareNameFormat, and so on. The old names are used for new macros which deal with literal lists. The complete list of affected macros is given in the changelog. Note that the names of the macros which dump the unformatted data have changes as well (\biblist -> \thename; \thelist (new); \bibfield -> \thefield). These changes will require updates to all custom citation and bibliography styles. However, the changes are only a matter of some search & replace commands. I'm sorry about the inconvenience but I think the new naming scheme is better than having macro names like \printliterallist. I've decided to go for it now since biblatex is still in beta. As part of these changes, the data type of the following fields has been changed from 'literal field' to 'literal list': location, origlocation, publisher, institution, organization. * Support for hyperref Hyperref support is available now. This means that citations may be transformed into links pointing to the bibliography. All standard citation styles support that out of the box, custom styles need to use the new hyperref interface. It works like this: the anchor (i.e. the target of the link) is set automatically by biblatex hence the bibliography style does not need to do anything special. The citation style is responsible for marking the link area. This is just a matter of passing the relevant part of the citation to a special macro or formatting directive doing the low-level work. See the changelog for pointers to the relevant sections of the manual. * Support for back references I've added support for back references. The page numbers are provided in the 'pageref' field which uses the new literal list data type. Printing them is just a matter of \printlist{pageref}. Note that you need to enable the 'backref' package option to get any back reference data. There is also a bibmacro called 'pageref' in biblatex.bbx which adds a label. Bibliography styles should print the list via \usebibmacro{pageref}. There are two related list formatting directives in biblatex.def. The default directive just prints the list as is, using a comma as a separator. The directive 'pageref:comp' prints a sequence of more than two consecutive pages as a range. The easiest way to try it out is: \DeclareListAlias{pageref}{pageref:comp}. The references are restricted to page numbers, back references to sections are not supported. This is a deliberate decision. I haven't bothered implementing back references to sections because LaTeX's referencing mechanism is notoriously unreliable in this respect. It essentially provides two pieces of information: the formatted value of the last counter incremented by way of \refstepcounter and the page number. The latter value is usually unambiguous but the former could refer to just about everything. The implications of this become obvious when you're using the backref package with its 'ref' option (rather than 'pageref') and put \cite commands in footnotes. The bibliography will then include something like 'sections 1, 2, 3', but these numbers do not refer to sections, these are footnote numbers! Getting back references to sections right would require reimplementing LaTeX's entire referencing mechanism (or interfacing with a package doing that) and I don't want to get into that business just yet. I may look into support for the zref package later, but that's something for a post-1.0 release of biblatex. * Rearranged author-title citation styles I've rearranged the author-title citation styles because most people seem to expect the behavior of the old 'authortitle-verb' style from the plain 'authortitle' style. So 'authortitle-verb' is the plain 'authortitle' style now. The style formerly known as 'authortitle' has been renamed to 'authortitle-terse', 'authortitle-comp' is 'authortitle-cterse' now. I've also added a new 'authortitle-comp' style to round off this subset of styles. * Handling of thebibliography/theshorthands streamlined The handling of thebibliography and theshorthands as well as some related facilities has been overhauled and streamlined. See the changelog and section 4.2.2 of the manual for details. * Handling of 'and others' simplified The way biblatex handles the string 'and others', which is used in bib files to truncate a list of names, has been overhauled and simplified. Essentially, I have removed 'moreauthor' and similar fields since biblatex handles this internally now. All style authors need to do is use \ifandothers and/or \ifmorenames. See the manual for details. * Improved \addtocategory \addtocategory now cycles its arguments through the aux file. This means that it may be used in the preamble and anywhere in the document body, even after \printbibliography. RELEASE NOTES FOR VERSION 0.2 * Internal changes in bibliography styles I have rearranged all bibliography styles. It should be more obvious now how many code is shared by the bibliography styles, namely all 'driver' code. The shared code has been moved to standard.bbx, so think of that as the biblatex standard style. This code is used by numeric.bbx, alphabetic.bbx, authortitle.bbx, and authoryear.bbx; standard.bbx is not meant to be used stand-alone. A few bibmacros have also been moved to biblatex.bbx. * Internal changes in citation styles There is only one change affecting the citation styles. The 'postnote' bibmacro in biblatex.cbx now automatically inserts a prefix like 'p.' or 'pp.' where applicable. * Optional argument for \printtext \printtext takes an optional argument now. The point is that you can use \printtext as a formatting hook. The advantage of this approach is that \printtext integrates with the punctuation tracking. I have revised biblatex.bbx to use this approach where applicable. * New fields There are several new fields, some of which are supported by the standard styles. This has lead to further changes in biblatex.bbx, including changes to the names of existing bibmacros.
