We recommend to update to the latest update of Kong (0.9.8) that ships with some significant bugfixes and performance improvements, especially if you are using Cassandra or Redis:
- Properly set the admin IP in the Serf script.
- Provide negative-caching for missed database entities. This should improve performance in some cases.
- Fix fault tolerancy logic and error reporting in rate-limiting plugins.
To update to the latest version, simply follow the installation instructions.
Upgrading from < 0.9.x
If you are migrating from an older version of Kong < 0.9.x, then follow the migration instructions in order to make your Kong cluster functioning after updating to 0.9.x.
