Platform has changed the way it accumulating logs when operating under subaccounts hierarchy.
Say you have account root with subaccount sub and it branched another subaccount subsub. Tree looks like this: root<=sub<=subsub.
Now imagine that you have log message for the subsub account, for example device was connected.
Before the update: logs both in realtime (subscribing to flespi/logs/#) and in history mode (accessible via REST) where placed by the system into an account subsub and all its parents: sub and root.
Thus when operating with large volumes we have quite a big storage size of root top-account basically multiplied by the number of subbaccounts it has.
After the update: the log message will be stored exactly and only at the account where it was generated. E.g if you have device or channel that belong to some subaccount you can access log messages for this entity only from its account. This is applied to both REST and MQTT.
Toolbox was modified accordingly and now has account selector whenever you have some flespi accounts to switch between.
