Lockfile update in the shape update.yml uses: nix flake update first, then cargo update. Both locks are coupled here — the nixpkgs input decides which rustc CI builds with.

flake.lock: Update

input	from → to
nixpkgs	2026-06-10 → 2026-10-20
rust-overlay	2026-06-12 → 2026-10-21
flake-utils	2024-11-13 → 2026-10-13
treefmt-nix	2026-05-31 → 2026-10-13
systems	2023-04-09 → 2026-10-05

The toolchain from that nixpkgs is rustc 1.99.0 (was 1.95.0).

Cargo update

Direct dependencies that moved:

crate	from → to
deadpool-sqlite	0.13.0 → 0.14.0
rusqlite	0.38.0 → 0.40.2
octocrab	0.51.0 → 0.54.5
cron	0.16.0 → 0.17.0
serde_regex	1.1.0 → 1.2.0
tokio	1.52.3 → 1.54.1
futures	0.3.32 → 0.3.34
clap	4.6.1 → 4.6.7
regex	1.12.3 → 1.13.1
serde / serde_json	1.0.228 → 1.0.229 / 1.0.150 → 1.0.154
chrono	0.4.44 → 0.4.45
log / thiserror / humantime	patch bumps

One source change was required: octocrab 0.54 made PullRequest::title an Option<String> (partial-response modelling). merged_pr_to_commit() now uses as_deref().unwrap_or_default(), so the generated commit comment starts with the configured comment when GitHub omits the title.

takecell stays at its bumped 0.1.2: it requires rustc 1.96, which the updated nixpkgs input now provides. (With the old flake it had to be pinned back to 0.1.1.)

Verified with the flake's own toolchain, rustc 1.99.0, i.e. what CI builds with: cargo check --all-targets, cargo test --all-targets (13 passed), cargo clippy --all-targets, cargo fmt --check.
