+Checkmate changelog
+===================
+
+Version 0.2.0
+-------------
+
+Released on September 25, 2017.
+
+ -  Now `CHECK` comments in source codes can be multiline.  The following
+    patterns are supported:
+
+     -  ~~~ c
+        /*
+        CHECK Lorem ipsum dolor sit amet, per facilis reprimique ut,
+        ei agam invenire mel.
+
+        Tacimates nominati vix ut, ea iudicabit prodesset deseruisse duo.
+        */
+        ~~~
+
+     -  ~~~ c
+        // CHECK Lorem ipsum dolor sit amet, per facilis reprimique ut,
+        // ei agam invenire mel.
+        //
+        // Tacimates nominati vix ut, ea iudicabit prodesset deseruisse duo.
+        ~~~
+
+ -  `CHECK` keywords with a colon (i.e. `CHECK:`) became matched.
+
+
+Version 0.1.4
+-------------
+
+Released on September 21, 2017.
+
+ -  Fixed a broken build of `checkmate` binary on the download page.
+    It was crashed on Linux distros that glibc is unavailable.
+
+
+Version 0.1.3
+-------------
+
+Released on September 20, 2017.
+
+ -  Fixed a broken build of `checkmate` binary on the download page.
+
+
+Version 0.1.2
+-------------
+
+Released on September 20, 2017.
+
+ -  Fixed a broken build of `checkmate` binary on the download page.
+
+
+Version 0.1.1
+-------------
+
+Released on September 20, 2017.
+
+### Program
+
+ -  Checklist texts generated by `checkmate commonmark`, `checkmate gfm`, and
+    `checkmate github` became to have two levels of headings.  The top-level
+    heading is still the title of the checklist as it has been, and the
+    second-level heading is a corresponding file path of its following checks.
+
+### Library
+
+ -  Added `Checkmate.Renderer` module.
+
+
+Version 0.1.0
+-------------
+
+Initial release.  Released on September 20, 2017.
