Client Retirement Plan 

Please note, the following version 1.x clients have too few users to justify
the effort to maintain these versions.
Therefore, these clients will be retired on or soon after the following
dates. We're sorry if one of these is your client version, but we do not
have the resources to continue to manage the porting of these clients.
