[michaelklishin]

v0.54.0 (Sep 19, 2025)

Enhancements

• FederationUpstream and ``FederationUpstreamParams` no longer have a "fidelity gap," a difference between fields
  that had made it impossible to convert the former into the latter
• FederationUpstream now includes several missing (rarely used) fields such as bind_using_nowait, channel_use_mode`

Breaking Changes

• FederationUpstream#prefetch_count and FederationUpstream#reconnect_delay were bumped to u32
