アップグレード ノート

Please read the following sections and take action where the note applies to your Crowd installation, before upgrading to the new release of Crowd.

Refer to the Crowd 2.1 Upgrade Notes

If you have not yet upgraded to Crowd 2.1, please read the Crowd 2.1 upgrade notes before upgrading to Crowd 2.2.

Automatic Database Upgrades Now Support Microsoft SQL Server

Microsoft SQL Server is now supported for automatic database upgrades, along with the existing support for PostgreSQL and MySQL.

Deprecation of Functionality -– Roles

This is an advance warning that Crowd 2.3 (a future release of Crowd) will no longer support roles. Roles are essentially groups with another name: they offer no functional benefit over groups. In Crowd 2.0, the namespace of groups and roles were merged so that it was not possible to have a group and role with the same name. Crowd 2.2 will support roles, but we encourage administrators to migrate the roles to groups as this feature will be removed entirely in the next major release.

Advance Notice of End of Support for Java Platform 5 (JDK/JRE 1.5)

This is an advance warning that Crowd 2.3 (a future release of Crowd) will no longer be supported on Java 5 (JDK/JRE 1.5). Crowd 2.2 will still run on Java 5. We encourage administrators to upgrade to Java 6 for Crowd 2.2 to ensure a smooth transition when upgrading to Crowd 2.3 in the future.


To upgrade to Crowd 2.2 from 2.1.x or earlier, please follow these upgrade instructions.
