 ## [0.2.2] - 2026-03-02
 
+Published: 2026-03-02T14:07:04Z
+
 ### Changed
 
 - Session storage key standardized to `"vex-session"`.
-- Login identity request now stores compact app info keys:
-  - `pi` (peer id), `na` (app name), `ic` (icon), `do` (origin), optional `auth` (cached proof).
-- Request method names standardized:
-  - `signRequest`, `signMessage`, `sharedSecret`.
+- Login identity payload compacted with standardized keys:
+  - `pi` (peer id)
+  - `na` (app name)
+  - `ic` (icon)
+  - `do` (origin)
+  - optional `auth` (cached identity proof)
+- RPC method names standardized:
+  - `signRequest`
+  - `signMessage`
+  - `sharedSecret`
 
 ### Added
 
-- `clearSession()` helper.
-- Session reuse:
-  - Reuses saved `peerID` and hints (`account@permission`) when present.
+- `clearSession()` helper for manual session reset.
+- Smart session reuse:
+  - Reuses stored `peerID`
+  - Reuses permission hints (`account@permission`) when available.
 
 ### Fixed
 
-- Safer session loading (auto-clears invalid or expired payloads).
-- Improved cleanup on disconnect (best-effort destroy/disconnect).
+- Hardened session loader:
+  - Automatically clears expired or malformed session payloads.
+- Improved disconnect cleanup:
+  - Safe destroy/disconnect (best-effort, non-throwing).
 
 ### Improved
 
-- Low-memory friendly behavior:
-  - Lightweight heartbeat/ping with jitter (best-effort).
-  - Minimal allocations on message routing.
+- Optimized for low-memory environments:
+  - Lightweight heartbeat with jitter
+  - Reduced message routing allocations
+  - Lower background CPU usage on mobile devices
