# While the official synapse version is updated, the idea is to test the migration with the new version.
# If the migration pass we can update this next line with the new synapse package.
# For more information see comment : https://github.com/YunoHost-Apps/synapse_ynh/pull/40#pullrequestreview-108680051

# Actually this package use pythonvirtualenvironnement. The old package used the debian package. So if the app is not already migrated from the old package version we need to migrade the app from the debian package to a python virtualenvironnement. In the same time the package migrated from sqlite to postgresql for the database. So we do these both things in the same time.
