+### Configuration
 
-<!--
 - New feature `tier` - a group of instances with own replication factor.
   Tiers can span multiple failure domains and a single cluster can have
   multiple tiers. Going forward it will be possible to specify which
   tier a table belongs to.
 
-- Order of columns in `_pico_service_route` table has changed.
-
-- Default authentication method changed from `CHAP-SHA1` to `MD5` both for user creation and in connect CLI. This change affects new user creation and all system users (except the `pico_service` user), as a command-line interface of `picodata connect` and `picodata expel`. Also, default schema version at cluster boot is now `1`, not `0` as it was previously.
-Connection via `Pgproto` no longer requires additional manual step to change the authentication method. However if you use `iproto` the admin will have to manually change the authentication type.
-
-- New `picodata connect` and `picodata expel` argument `--timeout` for specifying
-the timeout for address resolving operation.

 - Support human numbers to configure memtx.memory, vinyl.memory and vinyl.cache parameters.
   Supported suffixes: K, M, G, T, 1K = 1024
   (e.g picodata run --memtx-memory 10G)
 
-- Replace the use of `localhost` with `127.0.0.1` in `picodata run --listen` default value and everywhere across documentation and examples to reduce ambiguity.
