 - We can run startup integrity checks with lower memory use for healthy Vault files. Files that change between the size check and content reading no longer trigger an unnecessary repair warning when their actual sizes agree and there are no conflicts. (#1283)
 
+## 1.0.40
+
+24th October, 2026
+
+This has turned into a slightly larger set of changes overall, but I have finally been able to implement the features I felt we would need.
+
+### Synchronisation
+
+#### New Feature
+
+- We can choose **Review devices** in Remote Configuration, the command palette, or a version Notice to review participating devices.
+    - Our device appears first, with its lockout state. Other records show the platform, plug-in version, app version, and last recorded connection time when available.
+    - An advisory Notice identifies Self-hosted LiveSync and lists newer and older versions separately, with one shared recommendation and **Review devices** action. The dialogue explains possible storage costs and P2P compatibility limits.
+- We can forget records belonging to lost or retired devices while preserving the remote lock state and other devices.
+    - Forgetting a record does not delete Vault files or revoke credentials. A returning device can register again on an unlocked remote.
+
+#### Fixed
+
+- We can reuse unchanged content more reliably after edits with the V3 Rabin–Karp chunk splitter.
+    - Corrected rolling-window processing lets boundary detection recover after an insertion. Existing content remains readable, and installing this update does not trigger a full re-chunk of our Vaults.
+    - Chunk-size values 0 and 1 now use content-defined binary boundaries below their maximum lengths, improving reuse after an insertion instead of producing fixed-length pieces.
+    - Editing or explicitly rewriting a file, recreating its chunks, or rebuilding from our files can produce different chunk boundaries and additional chunks. Older and updated devices can retain different chunk layouts; this affects reuse and storage, not the file contents.
+- We can preserve all conflict branches, including deleted branches, during Fast Setup.
+    - A fresh, complete Fast Fetch can also hand its verified progress to ordinary synchronisation before file watching resumes, reducing the first subsequent identifier scan. Existing resume cursors and On Demand chunk retrieval retain their existing behaviour.
+
+#### Changed
+
+- New setup uses the same Chunk-size recommendation of 0 across remote types, and Setting Doctor no longer recommends increasing every self-hosted V3 configuration to 60.
+    - Setting Doctor no longer flags the saved **Enhance chunk size** value. When rebuilding with V3 Rabin–Karp, we recommend setting it to 0. This is now an efficient choice across all supported remote types.
+    - Existing explicit and agreed values are retained. Smaller Chunks favour reuse during editing, but increase document counts and can make first uploads and large rebuilds slower. Mostly immutable binary Vaults can still benefit from a larger explicit value.
+
+### Hidden File Sync
+
+#### Fixed
+
+- We can synchronise selected hidden files while the normal-file allow-list is set. (#1272)
+    - Normal-file exclusion patterns still apply to hidden files, and the Selector descriptions now explain their scope.
+
+### CLI
+
+- Unreadable or malformed device-local state now stops initialisation instead of being treated as empty. Existing valid state files keep their format.

-### Synchronisation
-
-#### Fixed
-
-- We can continue synchronising after rebuilding an encrypted CouchDB remote, including when Hidden File Sync and Customisation Sync are enabled. (#1234)
-    - This plug-in reads the rebuilt data without reusing HTTP responses encrypted with the previous Security Seed.
-
-### Customisation Sync
-
-#### Fixed
-
-- Customisation Sync now waits until this plug-in is ready before handling configuration file events, and applying settings while synchronisation is suspended no longer scans configuration files. (#1220)
-    - Resuming synchronisation scans once and restarts the periodic scan when enabled.
