 ## [Unreleased]
 
+## [0.3.1] - 2026-10-22
+
+The dependency-patch release: the alkcall substrate bumped 0.10.0 →
+0.10.1 (the adoption-window ordering fix) and the alktunnels sibling
+bumped 0.4.0 → 0.4.1 (its dependency-patch ride). No alksocks API
+change, no wire change; the fix surface is private upstream, so there
+is no change on this crate's paths. Patch rather than minor: both
+dependency bumps are semver-compatible (0.10.x → 0.10.1, 0.4.x →
+0.4.1), matching the alktunnels 0.4.0 → 0.4.1 ride.
+
+### Changed
+
+- **alkcall 0.10.0 → 0.10.1** (crates.io). The adoption-window
+  ordering fix (review 013, routed from alkgit's wave-2 gate): a
+  chunk routed by the channels demux inside the `adopt_channel`
+  install→drain window was delivered ahead of earlier-parked early
+  arrivals, inverting the channel's byte-stream order (observed
+  downstream as pkt-line desync in alkgit under multi-process load),
+  and a related loss variant (a chunk parked after the drain had
+  removed the queue, parked forever) is closed. The install and its
+  park-drain are one atomic section; no await runs inside it. Relevant
+  in principle to this crate's reverse-path adopt flow (the
+  bind-first establisher surfaces channels through the same adopt
+  path), though no change in this crate's own surfaces was needed —
+  the fix surface is private (`ChannelState`), the behavior only
+  strengthens. No API, wire-format, or documented-cap behavior change
+  upstream.
+- **alktunnels 0.4.0 → 0.4.1** (the dependency-patch ride on alkcall
+  0.10.1). No alktunnels API/wire change; the composed providers see
+  none of it.
+- **fuzz/shared harness pin** (the only file-level contacts are the
+  `Cargo.toml`s/`Cargo.lock` — plus the doc pins): the harness declares
+  its own `alkcall` pin (it constructs `ChannelOpenError` values for
+  the invariant functions), so the two pins must stay in lockstep —
+  bumped 0.10.0 → 0.10.1 with the substrate (a drifting pin produces a
+  duplicate-type compile failure, not silent drift).
