 All notable code changes to **Markdown Viewer** are documented here.
 Non-code commits (documentation, planning, README-only updates) are excluded.
 
+## v3.9.5-beta.4
+
+- **Description:** Refined the Storage and Backup experience so storage status stays compact and secure-file choices appear only when they are needed.
+  - **Backup:** Opening Backup now presents a focused confirmation modal with the **Include secure workspace files** choice and encrypted-file recovery guidance.
+  - **Usage:** Shows only the workspace's actual local storage usage; the browser quota estimate is no longer displayed.
+  - **Recovery guidance:** Warns that clearing this site's browser data deletes locally stored web documents.
+  - **Performance:** The backup ZIP library remains lazy-loaded only after confirmation, so application startup and document-opening paths are unchanged.

+
+## v3.9.5-beta.3
+
+- **Description:** Restored the earlier compact Storage and Backup interface without reverting the new storage behavior.
+  - **Storage UI:** Returned to the simple status list, recovery note, and checkbox-with-helper-text layout while retaining Documents, Usage, web location, and read-only persistence information.
+  - **Behavior:** Kept unlimited document storage, ZIP backup/import, encrypted Secret Workspace handling, automatic best-effort browser storage, and the fixed desktop vault unchanged.
+  - **Responsive:** Prevented the status list from collapsing in short landscape windows so every row remains available through the modal's normal scrolling behavior.

+
+## v3.9.5-beta.2
+
+- **Description:** Simplified Storage and Backup and made the desktop vault location deterministic.
+  - **Storage UI:** Replaced total-file wording with separate normal and secret document counts, kept Usage visible, added a logical IndexedDB location on the web, and moved encrypted-backup inclusion into a full-width accessible option card.
+  - **Browser Storage:** Uses best-effort browser storage by default with read-only status; removed the persistence request button and shortened the site-data deletion warning.
+  - **Desktop Vault:** Removed vault relocation and its external locator file. App-managed workspace files now use the fixed `Documents/Markdown Viewer Vault` path, which replacement binaries check automatically.
+  - **Performance:** Storage measurements still run only when Storage and Backup is opened, so startup and document-opening paths are unchanged.

+## v3.9.5-beta.1
+
+- **Description:** Added complete workspace backup, encrypted restoration, and destructive reset workflows across the web and desktop applications.
+  - **Storage and Backup:** Renamed the settings module, fixed its missing icon, added exact workspace usage and total file counts, and added ZIP backup/import with folder-structure preservation.
+  - **Encrypted Backups:** Added an opt-in control that includes Secret Workspace files as their existing AES-GCM ciphertext. Backups never decrypt secure content, and restored content still requires the original access key.
+  - **Reset Safety:** Reset now permanently clears documents, folders, preferences, Secret Workspace data, history, and trash. The confirmation provides a direct Backup route, disables repeated submission, and uses the application loading spinner.
+  - **Performance:** The ZIP engine remains lazy-loaded, while documents continue to use per-document storage, on-demand content loading, and the bounded 20-document in-memory cache.
+  - **Desktop:** Added offline JSZip packaging, binary ZIP filesystem permissions, seven-platform preview builds, SHA-256 checksums, and prerelease publishing.

 ## v3.9.4
 
 - **Description:** Expanded Markdown Viewer with durable media workflows, stronger document organization, reliable two-document split previews, and broader deployment and documentation coverage.

+- **Workspace and documents:** organize as many documents as available device storage permits in nested folders; use Recent, Favorites, search, tabs, bulk actions, and an encrypted Secret Workspace.
 - **Editing and review:** switch among Editor, Split view, and Preview; use formatting tools, custom undo/redo, Find and Replace, LTR/RTL direction, comments, and suggestions.

 ## Important Limits
 
-- The Workspace limit is 50 documents, including locked Secret Workspace counts and temporary Share Snapshot or Live Share tabs.
+- Markdown Viewer does not impose a document-count limit. The practical limit is available browser or filesystem storage.
+- Browser documents use per-document IndexedDB records and load content on demand. Browser storage is best-effort by default; **Storage and Backup** reports usage and status, exports a complete ZIP backup, or restores one.
+- Desktop workspace documents live as ordinary `.md` files under the fixed `Documents/Markdown Viewer Vault` path. App upgrades and executable replacement do not remove that vault.
+- Workspace backup ZIPs preserve folders and can include Secret Workspace ciphertext. Secure files remain encrypted and require the original access key after import.
 - A local Markdown file larger than 10 MB is rejected.
 - The public GitHub importer shows at most 30 Markdown files for a repository or folder result.
 - Managed source media is limited to 25 MiB before processing; stored payload limits are 300 KiB for still images, 5 MiB for GIFs, and 10 MiB for videos.
