+### Minor Changes
+
+- ae1e169: Large-room scale: the guest SDK now supports rooms of up to 1024 players.
+
+  - **Per-index frame baselines raised 16 → 1024, allocated lazily.** The SDK
+    used to silently drop `Send` for a roster index ≥ 16; the per-slot baseline
+    table is now sized for 1024 consumers but each ~45 KiB slot is allocated on
+    first commit, so guest linear memory tracks the ACTIVE roster, not the cap.
+    A broadcast (`Identical`) reconciles only allocated slots; a never-sent-to
+    slot recovers via its first send opening with a keyframe (unconditionally
+    accepted) — the same path as a roster change. No wire/ABI change.
+  - **Cross-callback roster cache.** The host re-sends the full member list in
+    every callback payload, but rosters change only on join/leave/index-shift.
+    The SDK now skims the member section's raw bytes (new additive
+    `wire.(*Rd).SkipStr`) and compares them to the previous callback's: on a
+    match the previously decoded `[]Player` is reused with zero allocation;
+    only a real roster change re-decodes. This replaces the roster fingerprint
+    hash (the byte compare is strictly stronger) and removes an O(members)
+    allocation from EVERY callback — which, under `-gc=leaking`, leaked the
+    roster at callback rate and OOM'd long-lived large rooms (~100 KB/callback
+    at 1000 players). Lifetime contract: the slice from `Room.Members()` is
+    valid for the duration of the callback; copy `Player` values you retain
+    (long-lived state should be keyed by `AccountID`, as before).
