---

## Previous Versions (v3.11.4 and earlier)

## Version 3.11.4 (2026-02-06) - RESTORE HEADER BOTTOM SPACING
- **Changed:** Restored 2px bottom padding to header (was 0px, now 2px)
- **Improved:** Small breathing room between system stats bars and Add Event button
- **Visual:** Better spacing for cleaner appearance

### CSS Change:
**eventlist-today-header**:
- `padding: 6px 10px 0 10px` → `padding: 6px 10px 2px 10px`

### Visual Result:
```
│  ▓▓▓░░ ▓▓░░░ ▓▓▓▓░  │  ← Stats bars
│                       │  ← 2px space (restored)
├───────────────────────┤
│  + ADD EVENT          │  ← Add Event bar
├───────────────────────┤
```

**Before (v3.11.3)**: No space, bars directly touch Add Event button
**After (v3.11.4)**: 2px breathing room for better visual hierarchy

## Version 3.11.3 (2026-02-06) - FIX ADD EVENT DIALOG & TEXT POSITION
- **Fixed:** openAddEvent() function now checks if calendar element exists before reading dataset
- **Fixed:** Add Event button no longer throws "Cannot read properties of null" error
- **Changed:** Add Event text moved up 1px (position:relative; top:-1px)
- **Changed:** Line-height reduced from 12px to 10px for better text centering
- **Improved:** openAddEvent() works for both regular calendars and sidebar widgets

### JavaScript Fix:
**Problem**: Line 1084-1085 in calendar-main.js
```javascript
const calendar = document.getElementById(calId);
const filteredNamespace = calendar.dataset.filteredNamespace; // ← Null error!
```

**Solution**: Added null check
```javascript
const calendar = document.getElementById(calId);
const filteredNamespace = calendar ? calendar.dataset.filteredNamespace : null;
```

**Why This Happened**:
- Regular calendar has element with id=calId
- Sidebar widget doesn't have this element (different structure)
- Code tried to read .dataset on null, causing error

### Text Position Fix:
**Before**:
- line-height: 12px
- vertical-align: middle
- Text slightly low

**After**:
- line-height: 10px
- position: relative; top: -1px
- Text perfectly centered

### What Works Now:
✅ Click "+ ADD EVENT" in sidebar → Dialog opens
✅ No console errors
✅ Text properly centered vertically
✅ Form pre-filled with today's date
✅ Save works correctly

## Version 3.11.2 (2026-02-06) - ADD EVENT DIALOG IN SIDEBAR
- **Added:** Event dialog to sidebar widget (same as regular calendar)
- **Changed:** Add Event button now opens proper event form dialog
- **Added:** renderEventDialog() called in renderSidebarWidget()
- **Fixed:** Add Event button calls openAddEvent() with calId, namespace, and today's date
- **Improved:** Can now add events directly from sidebar widget

### Add Event Button Behavior:
**Before (v3.11.1)**: Showed alert with instructions
**After (v3.11.2)**: Opens full event creation dialog

**Dialog Features**:
- Date field (defaults to today)
- Title field (required)
- Time field (optional)
- End time field (optional)
- Color picker
- Category field
- Description field
- Save and Cancel buttons
- Draggable dialog

### Technical Changes:
- Added `$html .= $this->renderEventDialog($calId, $namespace);` at end of renderSidebarWidget()
- Changed Add Event onclick from alert to `openAddEvent('calId', 'namespace', 'YYYY-MM-DD')`
- Dialog uses same structure as regular calendar
- Uses existing openAddEvent() and saveEventCompact() JavaScript functions

### User Flow:
1. User clicks "+ ADD EVENT" green bar
2. Event dialog opens with today's date pre-filled
3. User fills in event details
4. User clicks Save
5. Event saved via AJAX
6. Dialog closes
7. Sidebar refreshes to show new event

## Version 3.11.1 (2026-02-06) - FLUSH HEADER & ADD EVENT DIALOG
- **Fixed:** Removed bottom padding from header (was 2px, now 0)
- **Fixed:** Removed margin from stats container (was margin-top:2px, now margin:0)
- **Fixed:** Add Event bar now flush against header with zero gap
- **Changed:** Add Event button now shows helpful alert dialog instead of navigating to admin
- **Improved:** Alert provides clear instructions on how to add events

### CSS Changes:
**eventlist-today-header**:
- `padding: 6px 10px 2px 10px` → `padding: 6px 10px 0 10px` (removed 2px bottom)

**eventlist-stats-container**:
- `margin-top: 2px` → `margin: 0` (removed all margins)

### Add Event Button Behavior:
**Before**: Clicked → Navigated to Admin → Manage Events tab
**After**: Clicked → Shows alert with instructions

**Alert Message**:
```
To add an event, go to:
Admin → Calendar Management → Manage Events tab
or use the full calendar view {{calendar}}
```

### Visual Result:
```
│  ▓▓▓░░ ▓▓░░░ ▓▓▓▓░  │  ← Stats (no margin-bottom)
├────────────────────────┤
│  + ADD EVENT           │  ← Perfectly flush!
├────────────────────────┤
```

No gaps, perfectly aligned!

## Version 3.11.0 (2026-02-06) - ADD EVENT BAR FINAL POSITION & SIZE
- **Moved:** Add Event bar back to original position (between header and week grid)
- **Changed:** Font size reduced from 9px to 8px (prevents text cutoff)
- **Changed:** Letter spacing reduced from 0.5px to 0.4px
- **Fixed:** Text now fully visible without being cut off
- **Final:** Optimal position and size determined

### Final Layout:
```
┌─────────────────────────────┐
│  Clock | Weather | Stats    │  ← Header
├─────────────────────────────┤
│  + ADD EVENT                 │  ← Bar (back here, smaller text)
├─────────────────────────────┤
│  M  T  W  T  F  S  S        │  ← Week Grid
│  3  4  5  6  7  8  9        │
├─────────────────────────────┤
│  Today                       │  ← Event sections
└─────────────────────────────┘
```

### Text Size Changes:
**v3.10.9**: 9px font, 0.5px letter-spacing → Text slightly cut off
**v3.11.0**: 8px font, 0.4px letter-spacing → Text fully visible

### Why This Position:
- Separates header from calendar
- Natural action point after viewing stats
- Users see stats → decide to add event → view calendar
- Consistent with original design intent

## Version 3.10.9 (2026-02-06) - ADD EVENT BAR MOVED BELOW WEEK GRID
- **Moved:** Add Event bar repositioned from between header/grid to below week grid
- **Improved:** Better visual flow - header → stats → grid → add button → events
- **Changed:** Add Event bar now acts as separator between calendar and event sections

### New Layout:
```
┌─────────────────────────────┐
│  Clock | Weather | Stats    │  ← Header
├─────────────────────────────┤
│  M  T  W  T  F  S  S        │  ← Week Grid
│  3  4  5  6  7  8  9        │
├─────────────────────────────┤
│  + ADD EVENT                 │  ← Add bar (moved here!)
├─────────────────────────────┤
│  Today                       │  ← Event sections
│  Tomorrow                    │
│  Important Events            │
└─────────────────────────────┘
```
