3.1.9 is a maintance release for 3.1. If you have not upgraded to any 3.1 Vault version, see http://support.sourcegear.com/viewtopic.php?t=4294 for more information.

The following changes are included in this release:

GUI Client Only
Get Latest will no longer delete local files if a repository folder was deleted and new folder of same name was later added and the Perform Repository Deletions option is not set to "Do not remove local copy"

Server and Client Changes
Rollback of a shared file to a version that is the same name as a different file in one of its linked folders no longer produces an "Object could not be found" message, which required a server restart to correct.

Visual Studio Client
Deleted files in web projects in Visual Studio 2005 no longer get added back to the project if the Get Latest is done on the project file.

Web project files are now retrieved after an Open From Source Control when the Vault working folder had already been set to a location that is different from the location specified in the Open From Source Control.

Client/Server Version Compatibility
It is always recommended that your client and server versions match exactly (e.g., a 3.0.1 client should be connecting to a 3.0.1 server). 3.1.x clients are able to communicate with any 3.0.x or 3.1.x server, but specific bug fixes will not work correctly if they required both client and server changes. 3.1.x clients and servers are not compatible with 1.x or 2.x clients and servers.

Upgrading From Previous Versions
It is recommended that you backup your Vault database prior to an upgrade. This can be done from either the Vault Admin tool, or the SQL Enterprise Manager tool.

To upgrade from a previous installation of Vault, simply invoke the new installer, and choose the same options that were selected when Vault was previously installed. Program files and configuration settings will be automatically updated to reflect the upgrade. Note that the server installation will not delete your database unless you explicitly tell it to.

You may also safely uninstall Vault first, and then install the upgrade. As with installation, an uninstall will not delete your database unless you explicitly tell it to.

Important: If you are upgrading from a pre 3.1 version of Vault, the server installation will take longer than normal because the database needs to be converted to a new format.

Also, the client install will upgrade client cache files to a new format if you are currently on a pre 3.1 release. This will not affect upgrade times, but also will not allow you to revert back to a pre 3.1 client without losing client state information.
