This is a maintenance release with a number of fixes in RESTful APIs, OAuth for Twitter and facebook, and a number of improvements and cleanups in the core library. The only new features that we've added is in the Articles app. You can now upload a cover for a published article. You can see the change log for more details:
IMPORTANT NOTE: make a backup of your database before upgrading so if things went wrong, you would be able to recover.
Now run the following command in the root of your Anahita installation:
$ composer update
then run the database migration:
$ php anahita db:migrate:up
that should do it.
If you are using the master branch, you need to pull the code and then run the database migration.
