+
+* Remove 'ical' subcommand in favor of 'topydo ls -f ical'
+* Remove options highlight_projects_colors in favor of colorscheme options. In case you wish to disable the project/context colors, assign an empty value in the configuration file:
+
+      [colorscheme]
+      project_color =
+      context_color =
+* `del`, `depri`, `do`, `pri`, `postpone` now support now expression like `ls`
+  does, using the `-e` flag (Jacek Sowiński, @mruwek).
+* Fix `ls` when searching for a certain key:value where value is a string.
+* Disable auto archive when the option archive_filename is empty.
+* Add option auto_creation_date to enable/disable the creation date being added
+  to new todo items.
+* Calculate relative dates correctly in long-running `prompt` sessions.
+* `pri` also accepts priorities in the form (A), [A] or any other bracket.
+* Add `listcontext` and `listcontexts` as aliases of `lscon`.
+* Highlight tags when the value is one character long.
+* Cleanups

 * This Github page defaults to the **stable** branch which is for **bug fixes
   only**. If you would like to add a new feature, make sure to make a Pull
   Request on the `master` branch.

+* Use descriptive commit messages.

+### Coding style

+* Please try to adhere to the coding style dictated by `pylint` as much
+  possible. I won't be very picky about long lines, but please try to avoid
+  them.
+* I strongly prefer simple and short functions, doing only one thing. I'll
+  request you to refactor functions with massive indentation or don't fit
+  otherwise on a screen.
