Google\Cloud\Translate\V3\TranslationServiceClient not found

[stAn47]

It seems the TranslationServiceClient namespace changed, while the documentation still uses both versions:
https://github.com/googleapis/google-cloud-php-translate

Original class (not working via autoload now):
Google\Cloud\Translate\V3\TranslationServiceClient

New class (working ok with autoload)
Google\Cloud\Translate\V3\Client\TranslationServiceClient

The bug is:

• documentation
• pls explain your policy - can there be expected more breaking changes like this on other APIs ? (random change of classname/namespace without documentation).

Thanks, best regards,
stAn
