The short version

What changed, and why it matters

This is a routine maintenance update for the electrs Bitcoin server. It raises the minimum Rust compiler version, switches the underlying database library from a custom fork (electrs-rocksdb) back to the upstream rust-rocksdb project, and updates the required RocksDB version from 7.8.3 to 9.10.0. The release notes explicitly warn that older electrs versions will not be able to read the new database format and will need to reindex. There is no direct evidence in the commit of a security vulnerability being fixed.

Recommended action

Treat as a standard dependency and infrastructure maintenance update. Operators upgrading should plan for a full reindex because the RocksDB format is incompatible with prior electrs versions. Review upstream rust-rocksdb and RocksDB 9.10.0 release notes for any security advisories, but no immediate security action is indicated by this commit alone.
