ckb 0.205.0 (b75a785 2026-03-17)

[doitian]

Highlights

CKB v0.205.0 adds a Terminal module for the new CKB-TUI, proxy protocol support, and cargo-binstall compatibility. It enhances the export/import subcommand with range and verifier selection, introduces RPC logs subscription, and upgrades the Rust toolchain to 1.92.0. On the maintenance side, the Docker base image moves from Ubuntu Bionic to Focal and a security fix addresses RUSTSEC-2026-0007 in the bytes crate.
