Users coming from 6.7.5 must not upgrade to this version. Your license will be incompatible. Instead, if you seek an upgrade to an intermediate version before the next L.T.S. version, you must start from 7.3 or higher.
Pull Request Analysis
Pull Requests are now a first class citizen feature in SonarQube for Developer, Enterprise and Data Center Edition users.
If you are using GitHub, you need to be sure to NOT have the GitHub Plugin in your SONARQUBE_HOME/extensions/plugins directory.
New Edition Packaging
Commercial Editions are now distributed individually, so you directly get the features and functionalities that match your needs. This means that upgrade/downgrade from one edition to another is no longer possible within the SonarQube Marketplace. In order to use a different edition you must download its dedicated package, and have a license ready for using that edition.SonarSource
SonarQube 7.2 is the last version supporting PostgreSQL < 9.3. Starting from SonarQube 7.3 the minimal supported version of PostgreSQL will be 9.3: SONAR-10668
