 =========
 
+0.10.3 (2016-08-20)
+-------------------
+
+- Fixes #29. [Jonas Michel]
+
+  Reporting an error when the user's rate limit is exceeded causes
+  the script to terminate after resuming execution from a rate limit
+  sleep. Instead of generating an explicit error we just want to
+  inform the user that the script is going to sleep until their rate
+  limit count resets.
+
+
+- Fixes #29. [Jonas Michel]
+
+  The errors list was not being cleared out after resuming a backup
+  from a rate limit sleep. When the backup was resumed, the non-empty
+  errors list caused the backup to quit after the next `retrieve_data`
+  request.
+
+
+0.10.2 (2016-08-21)
+-------------------
+
+- Add a note regarding git version requirement. [Jose Diaz-Gonzalez]
+
+  Closes #37
+
+0.10.0 (2016-08-18)
+-------------------
+
+- Implement incremental updates. [Robert Bradshaw]
+
+  Guarded with an --incremental flag.
+
+  Stores the time of the last update and only downloads issue and
+  pull request data since this time.  All other data is relatively
+  small (likely fetched with a single request) and so is simply
+  re-populated from scratch as before.
+
+
+0.9.0 (2016-03-29)
+------------------
+
+- Fix cloning private repos with basic auth or token. [Kazuki Suda]
+
+0.8.0 (2016-02-14)
+------------------
+
+- Don't store issues which are actually pull requests. [Enrico Tröger]
+
+  This prevents storing pull requests twice since the Github API returns
+  pull requests also as issues. Those issues will be skipped but only if
+  retrieving pull requests is requested as well.
+  Closes #23.
+
+
