Nice To Have (Optional)

• feat(fuse): Expose MFS as FUSE mount point #10781
• boxo with feat(gateway): add cid copy button to directory listings  boxo#899
• config: Flag to disable Bitswap client and server #10717
• feat(config): expose ProviderSearchMaxResults #10773
• document docs: known issues with file/urlstores #10768
• Reprovide.Interval 0 seems ignored on staging? #10714
• TBD if we need gateway: range requests issue with big >5GiB files boxo#856
• feat(mfs): chroot command to change the root #8648 as fix for Ipfs daemon hangs when MFS root is not available locally #7183 (comment)
• Deployment plan for AutoNAT v2 #10091
  • AutoTLS: attempts to get cert when not publicly diallable #10570 (depends on autonatv2 client)
• Denylist support fixes and improvements
  • ipfs blockservice is incompatible with sessions ipfs-shipyard/nopfs#34 (NOfs content filtering is not applied to bitswap)
  • Support consuming https://badbits.dwebops.pub/badbits.deny rainbow#126 (same applies to Kubo)
    • denylist: ?format=car does not skip directly blocked CIDs #10361
    • HTTPSubscriber: detect when list is not append-only ipfs-shipyard/nopfs#39
    • HTTPSubscriber: check with If-None-Match or If-Modified-Since ipfs-shipyard/nopfs#38
• Update pubsub and add default validator #9684 + update to v0.12.0 with GossipSub v1.2 + 0.13.0
• TBD: turn Experimental.GatewayOverLibp2p=true into opt-in feature
  • this is "http over libp2p stream" instead of "http-only gateways + tls" – think about it as bitswap replacement, that can reuse HTTP client logic from HTTPSwap, but make requests over libp2p. the use case for this is to provide bitswap replacement for users who can't run http-only endpoint for some reason
  • we start rolling out server before client exists to ensure we can enable client in the future, and have working servers for testing
  • this is an opportunity to flesh out how Exchange.* will look like (with bitswap client|server, HTTPGatewayOverLibp2p server for now, and HTTPSwap client)
• feat(mfs): chroot command to change the root #8648
• datastore: metrics datastore configuration optional and off by default #10788
• bug: failed to establish port mapping: goupnp: error performing SOAP HTTP request after LAN (upnp) router restart #9759
• chore: use go-log/v2 #10801 (note: pushed to 0.36)
