On Friday, Google released a list of 86 changes it made to its search engine over June and July. Some of them were directly related to quality, some related to ranking, some related to mobile, some related to how it understands natural language, and others show a decreased dependency on keywords from Google's algorithms.
Many of the changes are related to the direct answer-style results Google provides for some types of queries. Each change on the list is accompanied by a related project, and the project codenamed "Answers," was the subject of 23 of the entries.
