Dolphin 7.3.5 Released

The 7.3.5 is a service update, focusing on the most critical enhancements and fixes. Since most updates are minor this build is considered stable and recommended for all production sites.  Notably, the Dolphin 7.3.5 adds support of reCaptcha v2, which is critical due to reCaptcha v1 service being discontinued on the 1st of April by Google.
