Changelog

0.5.0

Removed type and info fields from Message table and merged privacy field, previously into a separate table, into that table. In order to make the app work, when upgrading you should run the migrate_0_4_to_0_5.py script.
Added flask-login dependency. Now, user logins can be persistent up to 365 days.
Rewritten enrich filter, correcting a serious security flaw. The new filter uses a tokenizer and escapes all non-markup text. Plus, now the + of the mention is visible, but weakened; newlines are now visible in the message.
Now you can edit or change privacy to messages after they are published. After a message it's edited, the date and time of the message is changed.
Fixed a bug when uploading.
Moved the site name, previously hard-coded into templates, into config.py.

Adding quick mention. You can now create a message mentioning another user in one click.
Added mention notifications.
Adding an about section, footer, version number and license.
Improved repository with better README, CHANGELOG, requirements.txt and option to specify port on run_example.py
Split app config from app module.
Added the capability to specify post privacy. Now you can choose to post your message to the public, to friends (mutual followers) or only you.
Added the capability to log in specifying email instead of username.
Added the precise date of a message as a tooltip when hovering over the human-readable date.
Now Python 3 is enforced.

This version (and every version below) is not a true version, but was added later by repository owner in changelog only.
Added notifications (including count on top bar) and public timeline.
