Hello, two major changes were applied to avpops module in development branch (1.2.0): - avp_write() has been removed - same functionality is provided by assignment operator in routing blocks, together with latest commit of PV transformations - avp_aliases parameter has been removed from avpops module and introduced as core parameter. you can use it directly in core, in global parameters section in form of: avp_aliases="uuid=I:660;email=s:email_addr;fwd=i:753" The value is the same as it was for avpops parameter. Now the AVP aliases can be used directly in routing blocks. Cheers, Daniel
