  BTF-based pretty-printing is coming in a next release.
• libpcap-based filtering for XDP with --filter-track-xdp was fixed #603 #609 #635.
• pwru can filter based on sk_buff and xdp_buff fields #499. For example, you can use `skb->dev->ifindex == 42' to show traces of packets which are processed by a netdev with the interface index equal to 42.
• pwru was ported to run on RISC-V64 #604.
• Performance was improved for pwru trace outputting and process name resolution #634.
