We are declaring the future upgrade for filter expression form | flespi noc (eu)

We are declaring the future upgrade for filter expression format in various REST API calls. The most important and popular are the GET /devices/XXX/messages, GET /calcs/XXX/devices/YYY/intervals API calls. But also all calls for logs and statistics retrieval are affected as well as GET /channels/XXX/messages API call in serial mode together with containers and cdns in storage system. Take special care to the filter field in your API call. If you are using this field - you may be affected, if not - just be informed.

Once the whole upgrade is finished it will be possible to use extended expressions in requests with math functions, arithmetic operations, brackets for operations priority and so on. But so far we made simple compatibility mode that you need to adjust your requests to.
