Upgrading the Matrix services

This playbook not only installs the various Matrix services for you, but can also upgrade them as new versions are made available.

If you want to be notified when new versions of Synapse are released, you should join the Synapse Homeowners room: #homeowners:matrix.org.

To upgrade the services:

update your playbook directory (git pull), so you'd obtain everything new we've done
take a look at the changelog to see if there have been any backward-incomptabile changes that you need to take care of
re-run the playbook setup: ansible-playbook -i inventory/hosts setup.yml --tags=setup-all
restart the services: ansible-playbook -i inventory/hosts setup.yml --tags=start

Note: major version upgrades are not done to the internal PostgreSQL database. To upgrade that one, refer to the upgrading PostgreSQL document.
