 # Changelog
 
+## Changes 5/8/2025 v1.3.3
+
+### Enhancements
+
+- **Admin API** (`updateConfig.php`):  
+  - Now merges incoming payload onto existing on-disk settings instead of overwriting blanks.  
+  - Preserves `clientId`, `clientSecret`, `providerUrl` and `redirectUri` when those fields are omitted or empty in the request.
+
+- **Admin API** (`getConfig.php`):  
+  - Returns only a safe subset of admin settings (omits `clientSecret`) to prevent accidental exposure of sensitive data.
+
+- **Frontend** (`auth.js`):  
+  - Update UI based on merged loginOptions from the server, ensuring blank or missing fields no longer revert your existing config.
+
+- **Auth API** (`auth.php`):  
+  - Added `$oidc->addScope(['openid','profile','email']);` to OIDC flow. (This should resolve authentik issue)
+
+---
+
+## Changes 5/8/2025 v1.3.2
+
+### config/config.php
+
+- Added a default `define('AUTH_BYPASS', false)` at the top so the constant always exists.
+- Removed the static `AUTH_HEADER` fallback; instead read the adminConfig.json at the end of the file and:
+  - Overwrote `AUTH_BYPASS` with the `loginOptions.authBypass` setting from disk.
+  - Defined `AUTH_HEADER` (normalized, e.g. `"X_REMOTE_USER"`) based on `loginOptions.authHeaderName`.
+- Inserted a **proxy-only auto-login** block *before* the usual session/auth checks:  
+  If `AUTH_BYPASS` is true and the trusted header (`$_SERVER['HTTP_' . AUTH_HEADER]`) is present, bump the session, mark the user authenticated/admin, load their permissions, and skip straight to JSON output.
+- Relax filename validation regex to allow broader Unicode and special chars
+
+### src/controllers/AdminController.php
+
+- Ensured the returned `loginOptions` object always contains:
+  - `authBypass` (boolean, default false)
+  - `authHeaderName` (string, default `"X-Remote-User"`)
+- Read `authBypass` and `authHeaderName` from the nested `loginOptions` in the request payload.
+- Validated them (`authBypass` → bool; `authHeaderName` → non-empty string, fallback to `"X-Remote-User"`).
+- Included them when building the `$configUpdate` array to pass to the model.
+
+### src/models/AdminModel.php
+
+- Normalized `loginOptions.authBypass` to a boolean (default false).
+- Validated/truncated `loginOptions.authHeaderName` to a non-empty trimmed string (default `"X-Remote-User"`).
+- JSON-encoded and encrypted the full config, now including the two new fields.
+- After decrypting & decoding, normalized the loaded `loginOptions` to always include:
+  - `authBypass` (bool)
+  - `authHeaderName` (string, default `"X-Remote-User"`)
+- Left all existing defaults & validations for the original flags intact.
+
+### public/js/adminPanel.js
+
+- **Login Options** section:
+  - Added a checkbox for **Disable All Built-in Logins (proxy only)** (`authBypass`).
+  - Added a text input for **Auth Header Name** (`authHeaderName`).
+- In `handleSave()`:
+  - Included the new `authBypass` and `authHeaderName` values in the payload sent to `updateConfig.php`.
+- In `openAdminPanel()`:
+  - Initialized those inputs from `config.loginOptions.authBypass` and `config.loginOptions.authHeaderName`.
+
+### public/js/auth.js
+
+- In `loadAdminConfigFunc()`:
+  - Stored `authBypass` and `authHeaderName` in `localStorage`.
+- In `checkAuthentication()`:
+  - After a successful login check, called a new helper (`applyProxyBypassUI()`) which reads `localStorage.authBypass` and conditionally hides the entire login form/UI.
+  - In the “not authenticated” branch, only shows the login form if `authBypass` is false.
+- No other core fetch/token logic changed; all existing flows remain intact.
+
+### Security
+
+- **Admin API**: `getConfig.php` now returns only a safe subset of admin settings (omits `clientSecret`) to prevent accidental exposure of sensitive data.
+
+---
+
+## Changes 5/4/2025 v1.3.1
+
+### Modals
+
+- **Added** a shared `.editor-close-btn` component for all modals:
+  - File Tags
+  - User Panel
+  - TOTP Login & Setup
+  - Change Password
+- **Truncated** long filenames in the File Tags modal header using CSS `text-overflow: ellipsis`.
+- **Resized** File Tags modal from 400px to 450px wide (with `max-width: 90vw` fallback).
+- **Capped** User Panel height at 381px and hidden scrollbars to eliminate layout jumps on hover.
+
+### HTML
+
+- **Moved** `<div id="loginForm">…</div>` out of `.main-wrapper` so the login form can show independently of the app shell.
+- **Added** `<div id="loadingOverlay"></div>` immediately inside `<body>` to cover the UI during auth checks.
+- **Inserted** inline `<style>` in `<head>` to:
+  - Hide `.main-wrapper` by default.
+  - Style `#loadingOverlay` as a full-viewport white overlay.
+
+- **Added** `addUserModal`, `removeUserModal` & `renameFileModal` modals to `style="display:none;"`
+
+### `main.js`
+
+- **Extracted** `initializeApp()` helper to centralize post-auth startup (tag search, file list, drag-and-drop, folder tree, upload, trash/restore, admin config).
+- **Updated** DOMContentLoaded `checkAuthentication()` flow to call `initializeApp()` when already authenticated.
+- **Extended** `updateAuthenticatedUI()` to call `initializeApp()` after a fresh login so all UI modules re-hydrate.
+- **Enhanced** setup-mode in `checkAuthentication()`:
+  - Show `#addUserModal` as a flex overlay (`style.display = 'flex'`).
+  - Keep `.main-wrapper` hidden until setup completes.
+- **Added** post-setup handler in the Add-User modal’s save button:
+  - Hide setup modal.
+  - Show login form.
+  - Keep app shell hidden.
+  - Pre-fill and focus the new username in the login inputs.
+
+### `auth.js` / Auth Logic
+
+- **Refactored** `checkAuthentication()` to handle three states:
+  1. **`data.setup`** remove overlay, hide main UI, show setup modal.  
+  2. **`data.authenticated`** remove overlay, call `updateAuthenticatedUI()`.  
+  3. **not authenticated** remove overlay, show login form, keep main UI hidden.
+- **Refined** `updateAuthenticatedUI()` to:
+  - Remove loading overlay.
+  - Show `.main-wrapper` and main operations.
+  - Hide `#loginForm`.
+  - Reveal header buttons.
+  - Initialize dynamic header buttons (restore, admin, user-panel).
+  - Call `initializeApp()` to load all modules after login.

+
+## Changes 5/3/2025 v1.3.0
+
+**Admin Panel Refactor & Enhancements**  
+
+### Moved from `authModals.js` to `adminPanel.js`
+
+- Extracted all admin-related UI and logic out of `authModals.js`
+- Created a standalone `adminPanel.js` module  
+- Initialized `openAdminPanel()` and `closeAdminPanel()` exports
+
+### Responsive, Collapsible Sections
+
+- Injected new CSS via JS (`adminPanelStyles`)  
+  - Default modal width: 50%  
+  - Small-screen override (`@media (max-width: 600px)`) to 90% width  
+- Introduced `.section-header` / `.section-content` pattern  
+  - Click header to expand/collapse its content  
+  - Animated arrow via Material Icons  
+  - Indented and padded expanded content  
+
+### “Manage Shared Links” Feature
+
+- Added new **Manage Shared Links** section to Admin Panel  
+- Endpoint **GET** `/api/admin/readMetadata.php?file=…`  
+  - Reads `share_folder_links.json` & `share_links.json` under `META_DIR`  
+- Endpoint **POST**  
+  - `/api/folder/deleteShareFolderLink.php`  
+  - `/api/file/deleteShareLink.php`  
+- `loadShareLinksSection()` AJAX loader  
+  - Displays folder & file shares, expiry dates, upload-allowed, and 🔒 if password-protected  
+  - “🗑️” delete buttons refresh the list on success  
+
+### Dark-Mode & Theming Fixes
+
+- Dark-mode CSS overrides for:
+  - Modal border  
+  - `.btn-primary`, `.btn-secondary`  
+  - `.form-control` backgrounds & placeholders  
+  - Section headers & icons  
+- Close button restyled to use shared **.editor-close-btn** look
+
+### API and Controller changes
+
+- Updated all endpoints to use correct controller casing  
+- Renamed controller files to PascalCase (e.g. `adminController.php` to `AdminController.php`, `fileController.php` to `FileController.php`, `folderController.php` to `FolderController.php`)  
+- Adjusted endpoint paths to match controller filenames
+- Fix FolderController readOnly create folder permission
+
+### Additional changes
+
+- Extend clean up expired shared entries
+
+---
+
 ## Changes 4/30/2025 v1.2.8
 
 - **Added** PDF preview in `filePreview.js` (the `extension === "pdf"` block): replaced in-modal `<embed>` with `window.open(urlWithTs, "_blank")` and closed the modal to avoid CSP `frame-ancestors 'none'` restrictions.
