This section documents changes in the configuration which may require manual migration by the administrator. Typically
this only occurs when a configuration key is renamed or moved to a more appropriate location.
## Format
The migrations are formatted in a table with the old key and the new key. Periods indicate a different section which can
be represented in [YAML] as a dictionary i.e. it's indented.
In our table `server.host` with a value of `0.0.0.0` is represented in [YAML] like this:
```yaml
server:
host: 0.0.0.0
```
## Policy
Our deprecation policy for configuration keys is 3 minor versions. For example if a configuration option is deprecated
in version 4.30.0, it will remain as a warning for 4.30.x, 4.31.x, and 4.32.x; then it will become a fatal error in
4.33.0+.
## Migrations
### 4.33.0
The options deprecated in version [4.30.0](#4300) have been fully removed as per our deprecation policy and warnings
logged for users.
### 4.30.0
The following changes occurred in 4.30.0:
| Previous Key | New Key |
|:-------------:|:----------------------:|
| host | server.host |
| port | server.port |
| tls_key | server.tls.key |
| tls_cert | server.tls.certificate |
| log_level | log.level |
| log_file_path | log.file_path |
| log_format | log.format |
*__Please Note:__ you can no longer define secrets for providers that you are not using. For example if you're using the
[filesystem notifier](../notifications/introduction.md) you must ensure that the `AUTHELIA_NOTIFIER_SMTP_PASSWORD_FILE`
environment variable or other environment variables set. This also applies to other providers like
[storage](../storage/introduction.md) and [authentication backend](../first-factor/introduction.md).*
#### Kubernetes 4.30.0
*__Please Note:__ if you're using Authelia with Kubernetes and are not using the provided
[helm chart](https://charts.authelia.com) you will be required to
[configure the enableServiceLinks](../../integration/kubernetes/introduction/index.md#enable-service-links) option.*
### 4.25.0
The following changes occurred in 4.25.0:
| Previous Key | New Key |
|:-----------------------------------------------:|:-----------------------------------------------:|
| authentication_backend.ldap.tls.skip_verify | authentication_backend.ldap.tls.skip_verify |
| authentication_backend.ldap.minimum_tls_version | authentication_backend.ldap.tls.minimum_version |
| notifier.smtp.disable_verify_cert | notifier.smtp.tls.skip_verify |
| notifier.smtp.trusted_cert | certificates_directory |
*__Please Note:__ `certificates_directory` is not a direct replacement for the `notifier.smtp.trusted_cert`, instead
of being the path to a specific file it is a path to a directory containing certificates trusted by Authelia. This
affects other services like LDAP as well.*
### 4.7.0
The following changes occurred in 4.7.0:
| Previous Key | New Key |
|:------------:|:---------:|
| logs_level | log_level |
| logs_file | log_file |
*__Please Note:__ The new keys also changed in [4.30.0](#4.30.0) so you will need to update them to the new values if you
are using [4.30.0](#4.30.0) or newer instead of the new keys listed here.*
