I obtained an error when upgrading the application to that beta version.
bitnami@ip-172-31-2-51:/opt/bitnami/apps/discourse/htdocs$ sudo /opt/bitnami/ruby/bin/ruby bin/rake db:migrate RAILS_ENV=production

ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR: relation "group_category_notification_defaults" does not exist
LINE 8: WHERE a.attrelid = '"group_category_notification_defaults"'...
As it's a beta release, I understand the code can contain errors so I suggest you contact them to know if the upgrade process is already supported.
Regarding about what to do now, I suggest you these paths:
- If you created a backup of the instance previously, use it to recover it.
- If you didn't, move back to the previous version you had and install the gems again
git checkout Gemfile*
git checkout bin
git checkout tags/vYOUR_PREVIOUS_VERSION
git stash apply
gem install bundler -v BUNDLER-VERSION
bundle config default BUNDLER-VERSION
sudo bundle install --without development test sqlite --binstubs --deployment
sudo /opt/bitnami/ctlscript.sh start
The application should work now. I did that after getting the db:migrate error and everything is working as expected
