[xHeaven]

Changes that might be breaking

API changes

• Tempest\Core\Insight
  • Removed constants: Insight::ERROR, Insight::SUCCESS, Insight::NORMAL, Insight::WARNING.
  • Constructor now takes Tempest\Core\InsightType instead of a string constant.
• Tempest\Router\Exceptions\ConvertsToResponse
  • Now extends \Throwable.
  • Non-throwable implementations are no longer valid.
• Tempest\Auth\Authentication\DatabaseAuthenticatableResolver
  • Unused constructor with Database dependency was removed.
  • new DatabaseAuthenticatableResolver($database) no longer works.
• Tempest\Console\Exceptions\UnknownArgumentsException
  • Unused constructor parameter consoleCommand was removed.
• Tempest\Http\Session\Managers\FileSessionManager
  • Constructor dependency changed from SessionConfig to FileSessionConfig.
• Tempest\Reflection\EnumReflector
  • Constructor changed from string|object to string|UnitEnum|self|ReflectionEnum.
  • Passing arbitrary objects is no longer supported.
• Tempest\View\Elements\PhpDataElement
  • Class removed as it was entirely dead code.
• Tempest\View\ViewCachePool::getItem()
  • Return type changed from Symfony\Component\Cache\CacheItem to Psr\Cache\CacheItemInterface.

Positional argument changes

• Tempest\KeyValue\Redis\Config\RedisConfig
  • Added missing $persistentId before $timeout/$options parameters. If you are using named parameters, you are unaffected.
• Tempest\Log\Config\SlackLogConfig
  • Added missing $channels before $prefix and $tag. If you are using named parameters, you are unaffected.

Behavioral changes

• packages/mail/src/mail.config.php
  • Invalid MAIL_SMTP_SCHEME now throws InvalidArgumentException instead of silently defaulting.
• Tempest\DateTime\DateTime::fromParts() and Tempest\DateTime\create_intl_calendar_from_date_time()
  • Out-of-range years now consistently throw OverflowException.
• Tempest\Storage\Config\AzureStorageConfig::createAdapter()
  • Azure client wiring changed from BlobRestProxy to BlobServiceClient.

Ok we can merge all of these in 3.x without any issues. I consider all of these bug fixes for oversights, not proper breaking changes.

Also: for the config files, our documentation always shows the named argument approach, so those are fine as well.

@innocenzi can you double-check the pluralizer stuff?
