**Upgrade notes:**
This version makes revision files with bibliographies that had been broken due to an upgrade come back to life. Execute the following in the following order after upgrading:

1. Make a backup of your fidus writer folder and your database.

2. Transpile the JavaScript sources:


./manage.py transpile


3. If you are on a production machine, collect the static files:


./manage.py collectstatic


4. If you have a running Fidus Writer instance, restart it. The syntax depends on how you run it. If you run it using supervisor, the command is something like:


sudo supervisor restart fiduswriter


5. Migrate:


./manage.py migrate


6. Navigate to the document management screen at `https://YOUR_SERVER/admin/document/document/maintenance/` and click on the "Update all documents (DANGER)!" button. Wait until the upgrade is done.

7. Make sure that the document revision files have been upgraded correctly. Only then can you delete the folder `FIDUSWRITER_FOLDER/media/revision/` and `FIDUSWRITER_FOLDER/media/document-revisions-backup/`
