+## [0.4.1] - 2026-09-10
+
+The MSRV floor becomes honest: `rust-version` raises from 1.85 to
+1.88. The 1.85 claim was already false at the dependency level — the
+lockfile pins `alkcall 0.7.x`, and alkcall 0.7.1 raised its MSRV floor
+to 1.88 (the ecosystem MSRV audit: noq's 1.88 matching the QUIC path;
+iroh sits above at 1.91), so no 1.85 toolchain could build 0.4.0
+regardless of what Cargo.toml declares. The raise breaks no downstream
+that could build the crate before. No API or wire-format change;
+downstreams on caret requirements pick this up on their next `cargo
+update`.
+
+### Changed
+
+- **`rust-version` 1.85 → 1.88.** Verified on a real 1.88 toolchain
+  (full test suite, clippy). alktty's own code is 1.85-clean —
+  `cargo check` under a 1.85 toolchain passes with the pre-bump
+  lockfile — so the raise is dependency-driven only and needed no
+  clippy fixes. Behavior-identical.
+- **`alkcall` requirement updated to `0.7.1`; lockfile bumped from
+  0.7.0 to 0.7.1.** Version-requirement-only (0.7.x is already the
+  resolved family); alkcall 0.7.1 changed no type alktty touches.
