# Which Problems Are Solved
The membership fields migration timed out in certain cases. It also
tried to migrate instances which were already removed.
# How the Problems Are Solved
Revert the previous fix that combined the repeatable step for multiple
fill triggers. The membeship migration is now single-run as it might
take a lot of time. It is not worth making it repeatable. Instance IDs
of removed instances are skipped.

# Which Problems Are Solved
Memberships did not have a fields table fill migration.
# How the Problems Are Solved
Add filling of membership fields to the repeatable steps.
# Additional Changes
- Use the same repeatable step for multiple fill fields handlers.
- Fix an error for PostgreSQL 15 where a subquery in a `FROM` clause
needs an alias ing the `permitted_orgs` function.

# Which Problems Are Solved
setup step 41 cannot handle downgrades at the moment. This step writes
the instance domain to the fields table. If there are new instances
created during the downgraded version is running there would be domain
missing in the fields afterwards.
# How the Problems Are Solved
Make step 41 repeatable for each version
# Which Problems Are Solved
Scheduled handlers use `eventstore.InstanceIDs` to get the all active
instances within a given timeframe. This function scrapes through all
events written within that time frame which can cause heavy load on the
database.
# How the Problems Are Solved
A new query cache `activeInstances` is introduced which caches the ids
of all instances queried by id or host within the configured timeframe.
# Additional Changes
- Changed `default.yaml`
- Removed `HandleActiveInstances` from custom handler configs
- Added `MaxActiveInstances` to define the maximal amount of cached
instance ids
- fixed start-from-init and start-from-setup to start auth and admin
projections twice
- fixed org cache invalidation to use correct index

# Which Problems Are Solved
Instance domains are only computed on read side. This can cause missing
domains if calls are executed shortly after a instance domain (or
instance) was added.
# How the Problems Are Solved
The instance domain is added to the fields table which is filled on
command side.
# Additional Changes
- added setup step to compute instance domains
- instance by host uses fields table instead of instance_domains table
