   2016-01-XX Version 0.13.0 released
   ==================================
 
+  Once again we are proud to announce the latest release of the Nim compiler
+  and related tools. This release comes just 3 months after the last
+  release!
+
+  A new version of Nimble which depends on this release, has also been
+  released. See `this <http://forum.nim-lang.org/t/1912>`_ forum thread for
+  more information about the Nimble release.
+
+  This release of Nim includes over 116 bug fixes, many of which are related
+  to closures. The lambda lifting algorithm in the compiler has been completely
+  rewritten, and some changes have been made to the semantics of closures in
+  Nim as a result. These changes may affect backwards compatibility and are all
+  described in the section below.
+
+  With this release, we are one step closer to Nim version 1.0.
+  The 1.0 release will be a big milestone for Nim, because after that version
+  is released there will be no more breaking changes made to the language
+  or the standard library.
+
+  That being said, the next release will likely be Nim 0.14. It will focus on
+  improvements to the GC and concurrency. We will in particular be looking at
+  ways to add multi-core support to async await. Standard library improvements
+  are also on our roadmap but may not make it for Nim 0.14.
+
+  As always you can download the latest version of Nim from the
+  `download <download.html>`_ page.
+
+  Happy coding!
