 [pending release 1.12]
 
+  * New `--filter/-F` option to make it easier to run "filters"
+    (Pandoc AST transformations that operate on JSON serializations).
+    Filters are always passed the name of the output format, so their
+    behavior can be tailored to it.  The repository
+    <https://github.com/jgm/pandoc-filters-python> contains
+    a python module for writing pandoc filters in python, with
+    a number of examples.
+
+  * Added `--print-default-data-file` option, which allows printing
+    of any of pandoc's data files. (For example,
+    `pandoc --print-default-data-file reference.odt` will print
+    `reference.odt`.)
+
   * `--toc-level` no longer implies `--toc`.
     Reason: EPUB users who don't want a visible TOC may still want
     to set the TOC level for in the book navigation.

     addition, there are better error messages when fetching a URL fails.
 
+  * citeproc support has been removed from core pandoc (API changes).
+  
+    + The `--bibliography`, `--csl`, and `--citation-abbreviation` 
+      options have been removed.
+    + Markdown and LaTeX citations as still parsed, but an external
+      filter, `pandoc-citeproc`, is now needed to process
+      them against a bibliography and CSL stylesheet.  The bibliography
+      and stylesheet should be specified in the document's YAML metadata
+      (`bibliography` and `csl` fields), and the filter called with
+      `pandoc --filter pandoc-citeproc`.
+    + The `Text.Pandoc.Biblio` module has been removed, and the Markdown
+      and LaTeX readers no longer process citations.  Users of the
+      pandoc library who want citation support will need to use
+      `Text.CSL.Pandoc` from `pandoc-citations`.
+    + All bibliography-related fields have been removed from
+      `ReaderOptions` and `WriterOptions`: `writerBiblioFiles`,
+      `readerReferences`, `readerCitationStyle`.
+    + Note that a Cite element is now created in parsing markdown whether
+      or not there is a matching reference (indeed, pandoc has no way of
+      knowing, since the `--bibliography` option has been removed).
+      By default citations will print as `???`.
+    + The `pandoc-citeproc` script will put the bibliography at the
+      end of the document, as before.  However, it will be put inside a Div
+      element with class "references", allowing users some control
+      over the styling of references.  A final header, if any, will
+      be included in the Div.
+    * The markdown writer will not print a bibliography if the
+      `citations` extension is enabled.  (If the citations are formatted
+      as markdown citations, it is redundant to have a bibliography,
+      since one will be generated automatically.)
+ 
   * All slide formats: Support incremental slide view for definition lists.
 
   * Added syntax for "pauses" in beamer or reaveljs slide shows.

       If many variables with the same name are set, a list is created.
 
+  * `Format` is now a newtype, not an alias for String.
+    Equality comparisons are case-insensitive.

+  * New generic block container (`Div`) and inline container
+    (`Span`) elements have been added. These can take attributes.
+    They will render in HTML, Textile, MediaWiki, Org, RST and
+    and Markdown (with `markdown_in_html` extension) as HTML `<div>`
+    and `<span>` elements; in other formats they will simply pass through

+
+  * Added `Text.Pandoc.Walk` (in `pandoc-types`), which exports
+    hand-written tree-walking functions that are orders of magnitude
+    faster than the SYB functions from `Text.Pandoc.Generic`.
+    These functions are now used where possible in pandoc's code.
+    Added `Tests.Walk` to verify that `walk` and `query` match
+    the generic traversals `bottomUp` and `queryWith`.
+    (API change.)
+
+  * Added `Text.Pandoc.Process`, exporting `pipeProcess`.
+    This is a souped-up version of `readProcessWithErrorcode` that
+    uses lazy bytestrings instead of strings and allows setting
+    environment variables.  (Used in `Text.Pandoc.PDF`.)
+
+  * Added `Text.Pandoc.Compat.Monoid`.
