- The [services.caddy.acmeCA](#opt-services.caddy.acmeCA) option now defaults to `null` instead of `"https://acme-v02.api.letsencrypt.org/directory"`, to use all of Caddy's default ACME CAs and enable Caddy's automatic issuer fallback feature by default, as recommended by upstream.
- The default priorities of [`services.nextcloud.phpOptions`](#opt-services.nextcloud.phpOptions) have changed. This means that e.g.
`services.nextcloud.phpOptions."opcache.interned_strings_buffer" = "23";` doesn't discard all of the other defaults from this option
anymore. The attribute values of `phpOptions` are still defaults, these can be overridden as shown here.
To override all of the options (including including `upload_max_filesize`, `post_max_size`
and `memory_limit` which all point to [`services.nextcloud.maxUploadSize`](#opt-services.nextcloud.maxUploadSize)
by default) can be done like this:
```nix
{
services.nextcloud.phpOptions=lib.mkForce{
/* ... */
};
}
```
-`php80` is no longer supported due to upstream not supporting this version anymore.
