√ 2. Check for PHP 8.3 compatibility
√ 3. Check for jQuery 4 compatibility
√ 4. Update core version requirements to include Drupal 11
√ 5. Drop Drupal 8 and 9 support
√ 6. Unit tests are updated to work with Drupal 11 (PHPUnit 10)
√ 7. Automated tests pass D11 compatibility

D11 tests passed. Automated phpunit testing against Drupal 10 returned the following errors, due to this change.

1) Drupal\Tests\feed_block\FunctionalJavascript\RssTypesTest::testRss
Drupal\Core\Config\Schema\SchemaIncompleteException: Schema errors for block_content.type.feed_block with the following errors: block_content.type.feed_block:revision variable type is boolean but applied schema class is Drupal\Core\TypedData\Plugin\DataType\IntegerData

2) Drupal\Tests\feed_block\FunctionalJavascript\RssTypesTest::testYouTube
Drupal\Core\Config\Schema\SchemaIncompleteException: Schema errors for block_content.type.feed_block with the following errors: block_content.type.feed_block:revision variable type is boolean but applied schema class is Drupal\Core\TypedData\Plugin\DataType\IntegerData

I tested the D11-compatible code on a stock D10 site. Feed block revisions remain enabled even with boolean config value true, rather than 1.

√ 8. Change version numbering to use semantic versioning
