## Release 7.7 Upgrade Notes
**PR decoration below GitHub Enterprise 2.14 swapped for GitHub checks**
-This version adds support for GitHub Enterprise (GHE) checks, which were introduced in GHE 2.14, and drops support for PR decoration in GHE versions prior to 2.14. To use the new checks implementation, an application will need to be created in GHE, and further configuration will be required via the SonarQube UI. ([Details in the docs.](/instance-administration/github-application/).)

**ElasticSearch update requires index rebuild, potentially more filespace**
While it is generally possible to keep ElasticSearch indices in an upgrade (see [Configuring the Elasticsearch storage path](/setup/install-server/)), this version's upgrade of ElasticSearch will force all indices to be rebuilt. Additionally, more filespace may be required for this version's data ([SONAR-11826](https://jira.sonarsource.com/browse/SONAR-11826)).
