 ### Added
+- New funding and support details.
+- Custom issue templates. (#972)
 ### Changed
+- Use PSR-12 for code style.
+- Some general housekeeping. (#972)
+- [:exclamation:][unreleased-bc] Return an empty array for Entity properties with no items, instead of `null`. (#969)
 - `TelegramLog` now adheres to [PSR-3] `LoggerInterface` and allows custom logger implementations.
 ### Deprecated
 - Old logging that uses Monolog still works but will be removed in the near future. Use `TelegramLog::initialize($logger, $update_logger);` from now on.
 ### Removed
+- Botan.io integration completely removed.
 ### Fixed
+- `forward_date` is now correctly saved to the DB.
+- Broken `StickerSet::getStickers()` method.
 ### Security
+- Security disclosure managed by Tidelift.

 The easiest way to contribute is to work on a checkout of your own fork.
 When working on the `core` repository, it makes sense to rename your fork to `php-telegram-bot`.
 
-Before you contribute code, please make sure it conforms to the PSR-2 coding standard and that the unit tests still pass.
+Before you contribute code, please make sure it conforms to the PSR-12 coding standard and that the unit tests still pass.
 You can run the following commands to check if everything is ready to submit:
 
-    cd php-telegram-bot
-    composer install
-    composer check-code
+```bash
+cd php-telegram-bot
+composer install
+composer check-code
+```
 
 Which should give you no output, indicating that there are no coding standard errors.
 And then (remember to set up your test database!):
 
-    composer test
+```bash
+composer test
+```
 
 Which should give you no failures or errors. You can ignore any skipped tests as these are for external tools.
