## AGDNS-2048 / Build 750
* The environment variables `RESEARCH_LOGS` and `RESEARCH_METRICS` have been
removed.
## AGDNS-2022 / Build 746
* The property `block_page_redirect` of objects within `server_groups` array
has been removed.
## AGDNS-1981 / Build 744
* The objects within `server_groups` array had a change in their
`block_page_redirect` configuration, it now supports arrays of IP addresses
in `ipv4` and `ipv6` fields.
* Profile's file cache version was incremented. In case of
`BlockingModeCustomIP` the `profile.blocking_mode` IPv4/IPv6 fields are now
arrays of IP addresses.
## AGDNS-2012 / Build 732
* The querylog now has a new field, `"rn"`, which is a 16-bit unsigned random
number. Field `"u"`, the unique request ID, is deprecated and may be
removed in the future.
## AGDNS-1879 / Build 729
* Profile's file cache version was incremented. The new field
`authentication` has been added to profile's device object.
## AGDNS-1934 / Build 728
* The object `filters` has new properties: `index_refresh_timeout`, and
`rule_list_refresh_timeout`. So replace this:
```yaml
filters:
# …
```
with this:
```yaml
filters:
# …
index_refresh_timeout: 1m
rule_list_refresh_timeout: 1m
```
* The objects `safe_browsing` and `adult_blocking` have a new property:
`refresh_timeout`. So replace this:
```yaml
safe_browsing:
# …

adult_blocking:
# …
```
with this:

## AGDNS-1954 / Build 726
* The object `web` has a new optional property, `general_blocking`. Its
format is the same as in `adult_blocking` and `safe_browsing`.
