+  * Stripped out all JavaScript related code and documentation, moving
+    it to a separate repository (<https://github.com/jgm/commonmark.js>).
+  * Improved Makefile targets, so that `cmake` is run again only when
+    necessary (Nick Wellnhofer).
+  * Added `INSTALL_PREFIX` to the Makefile, allowing installation to a
+    location other than `/usr/local` without invoking `cmake`
+    manually (Nick Wellnhofer).
+  * `make test` now guarantees that the project will
+    be rebuilt before tests are run (Nick Wellnhofer).
+  * Prohibited overriding of some Makefile variables (Nick Wellnhofer).
+  * Provide version number and string, both as macros
+    (`CMARK_VERSION`, `CMARK_VERSION_STRING`) and as symbols
+    (`cmark_version`, `cmark_version_string`) (Nick Wellnhofer).  All of
+    these come from `cmark_version.h`, which is constructed from a
+    template `cmark_version.h.in` and data in `CMakeLists.txt`.
+  * Avoid calling `free` on null pointer.
+  * Added an accessor for an iterator's root node (`cmark_iter_get_root`).
+  * Added user data field for nodes (Nick Wellnhofer).  This is
+    intended mainly for use in bindings for dynamic languages, where
+    it could store a pointer to a target language object (#287).  But
+    it can be used for anything.
+  * Man renderer:  properly escape multiline strings.
+  * Added assertion to raise error if finalize is called on a closed block.
+  * Implemented the new spec rule for emphasis and strong emphasis with `_`.
+  * Moved the check for fence-close with the other checks for end-of-block.
+  * Fixed a bug with loose list detection with items containings
+    fenced code blocks (#285).
+  * Removed recursive algorithm in `ends_with_blank_line` (#286).
+  * Minor code reformatting: renamed parameters.
