#### UE address subnet
- Change default UE address subnet from 45.45.0.1/16 to 10.45.0.1/16 ([#369](https://github.com/open5gs/open5gs/pull/369)) -- [spencersevilla](https://github.com/spencersevilla)
#### New Features
###### Provide SGW GTP(S1) address to be advertised inside S1AP messages ([#367](https://github.com/open5gs/open5gs/pull/367)) -- [herlesupreeth](https://github.com/herlesupreeth)
This feature is useful in scenarios where SGW is run inside a container or openstack vm i.e. behind 1-to-1 mapping NAT. In docker/openstack environment, we often have 1-to-1 mapped NAT IP address in order for eNB to reach SGW. But, this 1-to-1 mapping NAT IP address is not seen on SGW host and hence non UDP socket bindable. Since SGW can only bind to IP address visible in it's host (usually a private IP beind a NAT), it advertises the same to UE in S1AP message resulting in eNB not able to reach SGW on Uplink. This commit solves this issue by providing a means to advertise a different IP address than the one SGW UDP socket is bound to.
###### Provide MTU size to be advertised in PCO options ([#376](https://github.com/open5gs/open5gs/pull/376)) -- [herlesupreeth](https://github.com/herlesupreeth)
This feature can be used for provisioning a limit on the size of the packets
sent by the MS to avoid packet fragmentation in the backbone network between
the MS and the GGSN/PGW and/or across the (S)Gi reference point) when some
of the backbone links does not support packets larger then 1500 octets
