-## Release Note: TBEL Date Formatting Changes (Java 21+)
-
-### Summary
-
-When upgrading ThingsBoard to Java 21 or later, users may notice changes in locale-formatted date/time strings produced by the `TbDate` class in TBEL scripts. These changes are caused by updates to the Unicode CLDR (Common Locale Data Repository) in Java 21+.
-
-### What Changed
-
-| Format | Java 17 | Java 21+ |
-|--------|---------|----------|
-| Time with AM/PM | `9:04:05 PM` | `9:04:05 PM` (narrow no-break space before AM/PM) |
-| Full datetime (English) | `Tuesday, September 5, 2023 at 9:04:05 PM` | `Tuesday, September 5, 2023, 9:04:05 PM` |
-| Full datetime (Ukrainian) | `середа, 6 вересня 2023 р. о 04:04:05` | `середа, 6 вересня 2023 р., 04:04:05` |
-| Short datetime (Arabic) | `5/9/2023, 9:04:05 م` | `5/9/2023، 9:04:05 م` (Arabic comma) |
-| UTC timezone display | `Eastern European Time` | `Kyiv (+0)` |
-
-### Impact
-
-TBEL scripts that rely on exact string matching or parsing of locale-formatted dates may behave differently after upgrading. For example:
-
-```javascript
-// ⚠️ May break after upgrade - string comparison
-var dateStr = new Date(ts).toLocaleString("en-US", "America/New_York");
-if (dateStr == "9/5/23, 9:04:05 PM") {
-    // Will fail - invisible character difference
-}
-
-// ⚠️ May break after upgrade - string splitting
-var parts = new Date(ts).toLocaleTimeString("en-US", tz).split(" ");
-// "PM" now preceded by narrow no-break space (U+202F), not regular space
-```
-
-### Recommendations
-
-1. **Use ISO formats for comparisons and storage**
-   ```javascript
-   // ✅ Stable across Java versions
-   var dateStr = new Date(ts).toISOString();  // "2023-09-05T21:04:05Z"
-   var dateJson = new Date(ts).toJSON();      // "2023-09-05T21:04:05.000Z"
-   ```
-
-2. **Use explicit patterns for consistent formatting**
-   ```javascript
-   // ✅ Explicit pattern - stable output
-   var dateStr = new Date(ts).toLocaleString("en-US", '{"pattern": "M/d/yyyy, h:mm:ss a"}');
-   ```
-
-3. **Use numeric getters for comparisons**
-   ```javascript
-   // ✅ Compare numeric values instead of strings
-   var d = new Date(ts);
-   if (d.getHours() == 21 && d.getMinutes() == 4) { ... }
-   ```
-
-4. **Avoid string equality checks on formatted dates**
-   ```javascript
-   // ❌ Avoid
-   if (date.toLocaleString() == storedDateString) { ... }
-
-   // ✅ Prefer
-   if (date.getTime() == storedTimestamp) { ... }
-   ```
-
-### Affected Methods
-
-The following `TbDate` methods may produce different output:
-- `toLocaleString()`
-- `toLocaleDateString()`
-- `toLocaleTimeString()`
-- `toString()`
-- `toDateString()`
-- `toTimeString()`
-- `toUTCString()`
-
-### Unaffected Methods
-
-These methods produce consistent output across Java versions:
-- `toISOString()`
-- `toJSON()`
-- `getTime()` / `valueOf()`
-- All numeric getters (`getFullYear()`, `getMonth()`, `getDate()`, `getHours()`, etc.)
