Updating docs for http client
Update docs/languages/en/modules/zend.filter.alpha.rst

Noting that the 'intl' extension is required for the Alpha filter to work, as it relies on the i18n module.
Alpha requires the intl extension

Zend\Filter\Alpha uses I18n, and therefore the intl extension for PHP must be installed.
Zend\Filter\Alnum requires intl extension

The Alnum filter needs the intl extension to PHP to be installed.

Additions to Zend\Filter docs
Update docs/languages/en/modules/zend.authentication.adapter.ldap.rst

I believe that addFilter is part of the $writer not the $logger.  With the example, I get the following error:

Fatal error: Call to undefined method Zend\Log\Logger::addFilter()

Also, it seems the parameters have been reversed for $logger->log() with priority now first.  With the example, I get the following error:

Zend\Log\Exception\InvalidArgumentException
$priority must be an integer > 0 and < 8; received 'Ldap: message'
