 Changelog
 =========
 
+0.11.0 (2016-10-26)
+-------------------
+
+- Support --token file:///home/user/token.txt (fixes gh-51) [Björn
+  Dahlgren]
+
+- Fix some linting. [Albert Wang]
+
+- Fix byte/string conversion for python 3. [Albert Wang]
+
+- Support python 3. [Albert Wang]
+
+- Encode special characters in password. [Remi Rampin]
+
+- Don't pretend program name is "Github Backup" [Remi Rampin]
+
+- Don't install over insecure connection. [Remi Rampin]
+
+  The git:// protocol is unauthenticated and unencrypted, and no longer advertised by GitHub. Using HTTPS shouldn't impact performance.
+
+0.10.3 (2016-08-21)
+-------------------
+
+- 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.
