# * `ed25519-dalek = 2`: 3.0 is pre-release (`3.0.0-pre.6`). Move to 3 once stable.
# * `chacha20poly1305 = 0.10`: 0.11 is `rc`. Same story.
# * `sha2 = 0.10` / `hkdf = 0.12`: **pinned by `mainline`**, which in turn
#   hard-pins `digest = "=0.11.0-rc.9"`. Bumping sha2 or hkdf requires either
#   a mainline release that relaxes the pin, or a coordinated fork. Attempting
#   `sha2 = 0.11` / `hkdf = 0.13` fails cargo-outdated and `cargo check`.
# * `rand = 0.9`: 0.10 is coordinated with iroh + bridge; hold until iroh bumps.
