file, together with the new `group` and `user` settings ([#2763]).
- Permissions on filter files are now `0o644` instead of `0o600` ([#3198]).
#### Configuration Changes
In this release, the schema version has changed from 10 to 12.
- Parameter `dns.querylog_interval`, which in schema versions 11 and earlier
used to be an integer number of days, is now a string with a human-readable
duration:
```yaml
# BEFORE:
'dns':
# …
'querylog_interval': 90
# AFTER:
'dns':
# …
'querylog_interval': '2160h'
```
To rollback this change, convert the parameter back into days and change the
`schema_version` back to `11`.
- Parameter `rlimit_nofile`, which in schema versions 10 and earlier used to be
on the top level, is now moved to the new `os` object:
```yaml
# BEFORE:
'rlimit_nofile': 42
# AFTER:
'os':
'group': ''
'rlimit_nofile': 42
'user': ''
```
To rollback this change, move the parameter on the top level and change the
`schema_version` back to `10`.
### Deprecated
- Go 1.16 support. v0.108.0 will require at least Go 1.17 to build.
