1.7.x

[BenjaminHoegh]

PHP Version Updates:

• .travis.yml: Removed support for PHP versions 5.3 through 7.0 new range is from 7.1 through 8.4.
• composer.json: Updated the minimum PHP requirement from >=5.3.0 to >=7.1.0.

Dependency Updates:

• composer.json: Adjusted the phpunit/phpunit dependency to remove support for versions below ^7.5.

Code Modernization:

• Parsedown.php: Updated method signatures for blockSetextHeader and blockTable to use nullable type hints (?array) for the $Block parameter. fixing the issue Implicitly marking parameter as nullable is deprecated

This should be safe to release as a 1.8 or 1.7.1 as the only breaking change is the PHP version and people do not really use that old PHP anymore

Parsedown.php:715

• The docblock above this method should be updated to reflect the new nullable type, for example @param array|null $Block.

    protected function blockSetextHeader($Line, ?array $Block = null)

Parsedown.php:853

• Please update the docblock for this method to indicate @param array|null $Block to match the nullable signature.

    protected function blockTable($Line, ?array $Block = null)

composer.json:16

• [nitpick] Consider updating the project README or CHANGELOG to call out the new minimum PHP requirement (>=7.1.0) so users are aware of the breaking change.
