## Limiting Unscoped Traffic

The new `flood.max.unscoped` CLI config variable is specifically for limiting unscoped flood traffic. Like `flood.max`, it drops unscoped flood packets which have already had a given number of hops. By default it is 64, which is essentially _off_.

## Limiting Advert Traffic

The new `flood.max.advert` CLI config variable is specifically for limiting adverts. Like `flood.max`, it drops advert packets which have already had a given number of hops. By default it is **8**.

## New Preamble

When using the lower Spreading Factors, the radio has less time to _lock onto_ an incoming packet, so this change gives the faster SF’s a longer preamble, and thus decreasing the chance of the preamble being missed. For SF \<= 8, the preamble is now 32 symbols.

## Improved Region Discovery in Mobile App

The new companion firmware, and latest app, will be able to do ad-hoc requests to near by repeaters _without_ having to add them to contacts first. This will streamline both repeater discovery, and region discovery.

## New `region def` Command

Defining regions via the CLI is currently quite verbose, and the latest CLI handling introduces a new `region def...` command which has a short-hand notation for defining regions, especially ones which have deep nesting.

See the [CLI Command Reference](https://docs.meshcore.io/cli_commands/) for more details.

## Extended ACK Support

The latest firmwares introduce support for ‘extended ACKs’, which are 6 bytes instead of 4. The extra bytes contain an extended attempt number, and additional random byte. This is in preparation for a later app feature which will enable much more than 4 attempts for direct messages. For now, repeaters will have to be updated first.

## Companion Raw Packets

The latest companion firmwares now enable apps to compose the _full_ packet, ie. headers, path and payload. This can correspond with the existing RxLog ability, so app can do its own raw send and receive of packets.
